Title: Automatic control device for gramophones
IPC: G11B19/14
Filed: 1943-01-08
Abstract: 557,284. Automatic gramophones. INDUSTRIAKTIEBOLAGET LUXOR. Jan. 8, 1943, No. 376. Convention date, Jan. 16, 1942, [Class 40 (ii)] Relates to devices automatically controlled at the end of the playing of a gramophone record to start a record-changing operation with return tone-arm, or to stop the gramophone. The device is of the kind comprising a blocking member 12 adapted to be moved in one direction by the tone-arm through an arm 21 frictionally coupled to the tone-arm and in the opposite direction by the oscillations of a member 6 under the influence of a spring 10 and a cam 5 driven by gearing 2, 3 from the turntable spindle 1, the arrangement being such that the oscillations of the member 6 about its pivot 7 causes its end 18 to engage the end 14 of the blocking member 12 and thereby deflect it out of blocking position, but the normal playing movement of the tone-arm returns the member 12 to blocking position, whereas when a concentric groove is at the end of a record, the cessation of the movement of the tone-arm leaves the member 12 in non-blocking position, whereupon the member 6 when allowed by the cam 5 is able to reach and operate a member 11 to perform the desired operation. According to the invention, the member 12 is arranged to have two non-blocking positions one on each side of the blocking position, so that the desired operation will be caused whether the tone-arm movement is stopped by a concentric groove or speeded up by a quick pitch groove. This is obtained by making the members 6 and 12 with teeth 19 and 15 facing each other, so that the tooth 19 will be unblocked whether the tooth 15 is displaced to the left or to the right of the tooth 19.

Wireless tuning-apparatus, adjustment devices for.-In two-speed adjusting-knobs for electrical instruments, the speed of the instrument spindle is determined by the engagement of a centrallymounted clutch-plate with either a stationary part or a part secured to the spindle. The instrument spindle B is driven from a knob T either directly, when a clutch member J is depressed into engagement with a disc R, or through a reducing-train K - - N, when the member J is forced by a spring Q against the top of a stationary housing H. The part J and a sleeve S carrying the knob T and gear-wheel K bear on a sleeve C, which carries or is integral with the gear-wheel N and is provided with a long internal thread to adapt it to varying lengths of instrument spindle, being locked thereon by a small screw D. The member J, which may be of metal or ebonite, preferably has facings 0, P of cork, rubber, or other friction material. It may have conical or toothed engaging-surfaces. The housing H, which may be gapped for a pointer W on the disc R, is bolted to a base E, which is pressed by a stiff spring F against the panel A so as to allow zero adjustment, rubber, cork, resin, &c. being interposed to increase the friction. In order to avoid the back-lash between the pinions K, L during direct drive, the clutch may be arranged between the members S, J or S, C. In a modification, the normal drive is direct, the slow speed being abtained by depressing or raising the' knob T.

Abstract: 553,009. Conveyers. WILSON, G. D., and BAKER PERKINS, Ltd. Jan. 12, 1942, No. 441. [Class 78 (i)] Means for preventing a canvas or like stretchable conveyer belt 1 from lateral movement comprise frictional or braking means 8, 14 located adjacent the belt-driving pulley, which, when the belt tends to wander to either side, automatically engage the corresponding edge of the belt and retard it, so that the driving pulley stretches or distorts the edge of the belt and exerts a pull thereon one component of this pull being transverse to the belt and opposite to the direction of displacement. The nearer the braking device is to the driving pulley the greater is the transverse component of the pull. In the construction shown in Fig. 3 the lower or return run of the belt passes over a round bar 6 mounted on springs 11 on rods 10 fixed to a bar 2 secured to the conveyer frame 4. Friction pads 8 are secured to the bar 6 and other friction pads 14 are secured to the bar 2, the opening between the friction pads being wedge-shaped so that if the belt 1 moves laterally from the central position shown it is braked by one or other pair of pads. The pads 14 are adjustable laterally on the bar 2 by means of slots 16, and the bar 2 is adjustable laterally of the conveyer on the frame 4. The brake pads may be disc shaped and may be carried entirely by the upper bar 2 or by a corresponding plate. In the construction shown in Fig. 8 the brake is provided by means of rollers 22, 23 which may themselves be braked or which may be driven through gearing 29, 26 at a slower rate than the belt or in the opposite direction. The braking devices may be brought into action by electrical relays when the belt is displaced laterally.

Title: Automatic tensioning apparatus in culm raising apparatus
Inventor: KITAKAZE KOICHI
IPC: F16H7/12
Filed: 1996-01-05
Abstract: PROBLEM TO BE SOLVED: To enabling the simplification of the structure and cost down in the subject apparatus. SOLUTION: In this automatic tensioning apparatus, a pulling-up chain 11 is supported by a pulling-up case 14 in a freely rotatably manner so as to move a pulling-up tine 10 along a pulling up path. The apparatus is provided with a tensioning sprocket 16 for imparting tension to the pulling-up chain 11 and a spring 17 which elastically moves the tensioning sprocket 16 in a direction to give tension to the pulling-up chain 11. An engaging member 26 is elastically engaged with plural stopping tines 25 formed on a controlling member 24 with spaces in the moving direction of the controlling member 24. This engaging mechanism prevents the motion of the sprocket in the direction opposite to give tension, in a state where the motion of a controlling member 24 in the direction giving tension is allowed.  In order to construct the controlling means, the controlling member 24 is attached on the pulling-up case 14 in a freely swingable manner around a rotary shaft center X2 of the tensioning sprocket 16, and the stopping tines 25 and the engaging member 26 are placed so as to engage and disengage with each other by the swing of the controlling member 24. A spring 16 is placed in such a state so as to generate a component force to swing the controlling member 24 in a direction to engage the stopping tines 25 with the engaging member 26.

Title: Switching power supply
Inventor: KOMATSU AKIYUKI
IPC: H02H3/24
Filed: 1995-01-05
Abstract: PURPOSE: To eliminate such conventional circuit as a comparator and to simplify circuit configuration for preventing the overdischarge of a battery when the battery is used as an input power supply and for protecting an internal circuit when the output side is short-circuited. CONSTITUTION: When starting up an input power supply 1, a PWM control circuit 2 is allowed to oscillate and outputs a pulse-width-modulated alternating current by a pulse from a start signal generation circuit 3 and a switching power supply continuously operates. When an I/O voltage decreases, the PWM control circuit 2 performs control so that the outputted on pulse width can be extended. When the input voltage approaches the output voltage or a load 6 is heavy, the pulse wave outputted from the PWM control circuit 2 becomes DC, thus causing an I/O protection circuit 4 to break the feedback to the PWM control circuit 2 and to stop the switching power supply.

Title: Analysis reagent
Inventor: SAKAINO YOSHIKO
IPC: G01N21/78
Filed: 1998-01-05
Abstract: PROBLEM TO BE SOLVED: To simply and rapidly analyze a harmful substance such as an organic chlorine compound and benzene at a field requiring a measurement, by containing an imidazole host compound expressed by an expression. SOLUTION: An imidazole host compound is, for example, 4,5-bis(4-1- methoxyphenyl)-2-(2-nitrophenyl)imidazole or the like. A harmful substance to be analyzed may be one causing a color tone by allowing a host compound to include, for example dichloromethane and chloroform. An inclusion reaction is made by a non-solvent reaction or a reaction in a solvent. In the case of the non-solvent reaction, the host compound is directly mixed and dissolved at a proper ratio. For example, reaction temperature and reaction time should sufficiently be 10-50 deg.C and 0.1-24 hours, respectively. In the case of the reaction in a solvent, a solution where the host compound is dissolved in a solvent such as methanol and chloroform is reacted with a guest compound, thus making solid an included compound for depositing and hence filtering and separation.

Title: Method for sensing wear of road surface
Inventor: FUKUCHI KEISUKE
IPC: G01K3/00
Filed: 1993-01-06
Abstract: PURPOSE:To automatically and effectively sense the wear of a road surface as a variation in a temperature distribution under the road surface without manual operation by using an optical fiber temperature distribution detecting sensor. CONSTITUTION:First, optical fibers 21, 22, 23, are laid in the same depths under a flat road surface 11. However, ruts 2, 2 are formed in the surface 11 above the fibers 22, 23 due to the wear of the surface 11. Then, the fibers 22, 23 of the worn part of the surface are easily affected by thermal influence from the surface 11 as compared with the fiber 21 of a non-worn part of the surface. Thus, diurnal temperature change 31, 32, 33 of the fibers 21, 22, 23 are different, and the worn state of the surface 11 can be sensed by the temperature changes.

Title: Image stabilizing device
Inventor: YAMAGISHI AKIRA
IPC: G02B27/64
Filed: 1987-01-07
Abstract: PURPOSE:To simplify the constitution of an image stabilizing device and reduce its size, and to facilitate its incorporation in an existent video camera by controlling the positions of plural wedge type prisms which are used in combination individually through a gyroscope. CONSTITUTION:The attitude of the video camera is detected by the gyroscope 8 and the two wedge type prisms 5 and 6 which are provided on the image side of the optical system of the camera and rotatable around an optical axis are rotated independently by drivers and motors 27 and 22, and 28 and 23. Consequently, the deflection angles of the prisms 5 and 6 to subject light vary to correct a shift in image formation focal plane due to the hand shake vibration of a long-distance subject, thereby attaining image stabilization. This simple, small-sized constitution allows the image stabilizing device to be easily incorporated in the existent camera.

Title: Adaptive digital filter system
Inventor: KOBAYASHI MASAKI
IPC: H03H17/00
Filed: 1987-01-07
Abstract: PURPOSE:To estimate an unknown system correctly by connecting plural adaptive digital filters in cascade and using a signal being the result of sequential addition of outputs of a linear noncyclic type digital filter of each basic section as an output of the adaptive digital filter so as to prevent the deterioration in the convergence characteristic of the variable multiplication coefficient. CONSTITUTION:The pole of multiplication coefficients am, bm of the secondary cyclic type digital filter is arranged near the unit circle on the (z) plane and input signals to variable coefficient multipliers of the linear noncyclic digital filter are made orthogonal. Moreover, variable multiplication coefficient Cm, Dm are selected so as to make the square mean values of the input signals equal to each other. Thus, even if the input signal has a color, the variable multiplication coefficients Cm, Dm are converged at a high speed. Furthermore, the output of the unknown system passes through the cyclic digital filter and the output of the adaptive digital filter is subtracted from the output of the filter. Then, the subtracted signal is formed to be the output of the system via the noncyclic digital filter having an inverse transfer function of the cyclic digital filter, then the unknown system is estimated correctly.
