Title: Improvements in Methods of Generating the Teeth of Helical Gear Wheels.
Inventor: BRADNER HOSEA TOWNSEND
IPC: B23F5/22
Filed: 1918-01-15
Abstract: 112,779. Bradner, H. T., (Assignees of Schurr, C. H.). Jan. 15,1917, [Convention date]. Gear-cutting.-Relates to cutting helical gears by means of a rotary hob and comprises a method in which definite ratios are established between the rotation of the blank, the rotation of the hob, and a relative feed movement with reference to a third rotating member, so that two of such ratios can be varied independently of the other. A machine for carrying out this method is shown to some extent diagrammatically. It is driven by a pulley 1 which, through gear shown, drives a helical wheel 5 in gear with two wheels 6, 7. The wheel 6 is on a shaft 8 and through the index change-gear 9, a shaft 10 bevel gear and spur gear including changewheels 15, 16 drives a shaft 22 carrying a worm 23 by which a worm wheel on a table carrying the blank 25 is driven. The shaft 10 through worm gear 59, 40, a clutch 41, spur gear 44, 45, 46 and other worm gear 48, 49 also drives a shaft 50 which is geared to a spindle 64 carrying a worm. This spindle can be swung to place the worm in gear with a worm wheel 66 on the screw 61 which moves the table to and from the hob 36 for instance when a worm-wheel is to cut. The screw can also be rotated by the hand-wheel 60. The shaft 50 is also bevel-geared to a vertical spindle 53 which, as shown in Fig. 2, is bevel geared to' a feed-screw 59 for the cutter slide. The cutter spindle 35 is carried in a head 37 which can be swiveted on the slide and is secured in position by bolts. The wheel 7 is mounted on a vertical shaft 26, which, through two sets of bevel-gear and a short shaft 29, drives a spindle carrying a long pinion 33 in gear with a pinion on the cutterspindle. The various change gears are ascertained partly by calculation from formula given in the Specification and partly from charts or diagrams, examples of which are given also in the Specification.

Abstract: 1,254,171. Grain dryers. LITOVSKY NAUCHNO - ISSLEDOVATELSKY INSTITUT MEKHANIZATSII I ELEKTROFIKATSII SELSKOGO KHOZYAISTVA. 7 Jan., 1969, No. 905/69. Heading F4G. An apparatus for forced air grain drying comprises a number of heating elements which are switched successively in dependence on temperature difference between inlet and outlet air, the temperature sensors being connected in a bridge circuit controlling a reversible stepping switch connecting the heating elements on unbalance of the bridge circuit. When the drying has reached the required value, the drying is discontinued. Inlet and outlet air temperature sensors 4, 5 and a switchable ambient temperature sensor 11 are connected into a bridge circuit 13. The circuit is put into operation by moving a switch 34 into position B and momentarily closing a manual switch 29 also switches 32 which energize heaters (not shown) through relay coils 10. When the air temperature has stabilized, as indicated by a micro ammeter (not shown) switch 34 is moved manually to the reverse position A. The bridge is connected to an amplifier 35 which closes contacts 36 energizing a relay 37, 38 causing stepping switch 16 to move to the left thus energizing contact 20 and consequently making one heater operative. A time delay relay 9 is also actuated concurrently which temporarily prevents further operation of the stepping switch 16. At the end of the delay if the bridge still has an output a further heater is energized. When the moisture absorbing capacity of the arrangement reaches 1À1 g./kg., unbalance of the bridge causes contacts 39 to close energizing a relay 40, 41 moving the bridge 16 successively to the right hence disconnecting contacts 18, 19, 20 in turn thus de-energizing the heating elements successively, and at the same time making on contacts 24, 25 thus operating relay 28 which opens contacts 42 thus preventing further movement of bridge 16 and stopping the drying procedure. Relay 27 is also deenergized through contacts 22, which opens contacts 43. Contact 21 may energize a fan motor (not shown) through a relay 26.

IPC: G11B7/24073
Filed: 1990-01-08
Abstract: PURPOSE:To obtain the reproducing waveforms faithful for recording signals and to lessen the recording left without being erased as well as to improve a recording sensitivity by forming this member in such a manner that the front surface of the recording film in land parts exists upper than the rear surface of the reflecting layer in grooves and exists in a range up to 50nm on the front surface but the rear surface of the recording film in the land parts exists lower than the front surface of the reflecting layer in the groove parts and in the range up to 50nm of the rear surface. CONSTITUTION:The member is so formed that the front surface of the recording film 3 in the land parts exists upper than the rear surface of the reflecting layer 5 in the grooves and exists in the range up to 50nm on the front surface but the rear surface of the recording film 3 in the land parts exists lower than the front surface of the reflecting layer 5 in the groove parts and in the range up to 50nm of the rear surface. The film thicknesses of the respective layers on the side faces are reduced by steepening the inclination of the side faces in contact with the lands and the grooves. The heat generated in the thin film 3 for recording is hardly diffused in this way even if the irradiation with a beam for recording is received. The laser power necessary for recording is decreased and the sensitivity of the recording member is enhanced.

Title: Method for adjusting resonance frequency of high frequency resonator
Inventor: ISHIKAWA YOHEI
IPC: H01P3/18
Filed: 1995-01-06
Abstract: PURPOSE: To precisely adjust resonance frequency in a practical manufacturing process without increasing the mounting area of a circuit. CONSTITUTION: This resonance frequency adjusting system is provided with a 1st transmission line LN10 and 2nd transmission lines LN1 to LN4 set up at least to one TEM mode which are costituted of alternately laminating thin film conductors and thin film dielectrics. The film thickness and dielectric constants of respective thin film dielectrics are set up so that the phase speed of electromagnetic waves propagated through the 1st and 2nd transmission lines LN10, LN1 to LN4 practically coincide with each other. The film thickness of thin film conductors other than the uppermost layer one is set up to a value thinner than the surface depth of applied frequency and the electromagnetic fields of the 1st and 2nd transmission lines LN10, LN1 to LN4 are set up so as to be connected.  Thus the resonance frequency of a high frequency resonator provided with high frequency transmission lines with prescribed size can be adjusted by changing the thickness of thin film conductors.

Title: Liquid fuel combustion device
Inventor: OGINO TOSHIRO
IPC: F23D5/04
Filed: 1987-01-06
Abstract: PURPOSE:To reduce the size of an evaporating chamber and to shorten a rise time, by a method wherein a combustion chamber is formed with a gap between a burner port cylinder and a heat collecting cylinder, a disc-like partition, having an opening part, is situated to the heat collecting cylinder, and an evaporating chamber is formed with a gap between an evaporating surface and the partition disc. CONSTITUTION:Fuel fed to an evaporating chamber 6a is evaporated by an evaporating surface heated by an electric heater 2, and the evaporated fuel, mixed with a small amount of air fed to the evaporating chamber 6a, flows through an opening part 3a of a partition disc 3 to a combustion chamber 6. The air-fuel mixture is burnt while it is mixed with air fed to the combustion chamber 6 through bores 4a of a burner port cylinder 4 and is diffused. In this case, particles of fuel mixed in evaporated gas are brought into contact with the partition disc 3 and is evaporated, and all fuel becomes evaporated gas to effect excellent blue flame combustion. Flame is formed in a direction extending from the pores 4a of the burner port cylinder 4 to an internal periphery to heat a heat collecting cylinder 1 erected at the inside. Thus, since the temperature of an evaporating surface 1a and the partition disc 3 is raised by means of heat conducted from the heat collecting cylinder, evaporation and combustion are continued by means of a self-heat. Further, since flame is formed in an internal direction, the diameter of the flame is reduced, and the diameter of a combustion chamber on the downstream side of the combustion chamber 6 can be reduced.

Title: Detector of electromagnetic flowmeter
Inventor: KAWAMATA ISAMU
IPC: G01F1/58
Filed: 1985-01-09
Abstract: PURPOSE:To enable the min. suppression of the change in the output of a detec tor due to offset flow by making the magnetic flux distribution in the detector non-uniform inclusive of a cross-section containing an electrode and a pipe axial direction, by providing a means for reducing a weighing function to the electrode output of an electrode peripheral part. CONSTITUTION:When the change in a flow speed is generated in the vicinity of electrodes 3, 4, the change in detected electromotive force becomes large as compared with other area and, in order to obtain electromotive force accurately proportional to a flow speed even with respect to offset flow, it is necessary to reduce the value of the weighing function. Therefore, notches 11 are provided to upper and lower magnetic electrodes 7, 8 for supplying magnetic flux to the vicinities of the electrodes 3, 4 and, by these notches 11, magnetic flux density is rapidly reduced outside the right angle plane of a pipe axis including the mount surface of the electrodes 3, 4 but increased in the axial direction before and behind said right angle plane and, by this effect, the values of the weighing function are lowered both in the pipe cross-section and pipe axial direction of a conduit 1.
