Title: Improvements in and relating to dynamic braking control systems for electric motors
Inventor: SIMONS DAVID SPENCER
IPC: H02P3/24
Filed: 1955-01-11
Abstract: 787,652. Control of A.C. motors. BRITISH THOMSON-HOUSTON CO., Ltd. Jan. 4,1956 [Jan. 11, 1955], No. 875/55. Class 38 (3). An induction motor has its stator winding supplied with direct-current for braking an overhauling load and the rotor resistance is automatically reduced as the braking operation proceeds, means being provided for automatically decreasing the rate of reduction of the resistance when such operation would cause reduction of the flux in the machine below a predetermined value. The rotor resistance may be of the liquid type operated by an hydraulic servo device having two different rates of travel, the change-over from the higher to the lower rate being initiated by an electrically-operated hydraulic valve. The valve is actuated in dependence upon a saturable detector having a current-voltage characteristic similar to that of the device used in conjunction with the system of Specification 666,561 and being connected across one phase of the rotor windings in series with the coil of a relay for operating the hydraulic valve. Alternatively, the output of the saturable device is applied to a control coil through a potentiometer, Figs. 1, 2 (not shown). In another arrangement, the rotor resistance is controlled by a number of contactors and a pre-determined degree of energization of the relay coil prevents further reduction of the resistance despite progression of the master controller, Fig. 3 (not shown). As shown, an electric servomotor SM controls the rotor resistance and is supplied from amplidyne A, the field winding F of which is energized in accordance with the difference between the voltage generated by a tachometer generator T, driven by the motor under control, and a reference voltage V. When a voltage derived from a saturable device 2 and potentiometer P exceeds a reference voltage at RR, field winding CF is excited and the servo operation is modified to prevent undesired reduction of the rotor resistance. The servo device may be of the hydraulic type controlled in response to speed deviation, the detector device controlling a valve to check the reduction of rotor resistance. In another arrangement, the rotor resistance is both increased and decreased to maintain the flux in the induction motor constant when its speed varies. The output from a detector 2 supplies one field winding of the amplidyne which has another opposing winding excited from a source of constant direct-current. Variations in the current output of the detector control the amplidyne and servomotor in both senses.

Title: Tracking device of optical disk track
Inventor: YONEZAWA SEIJI
IPC: G11B7/12
Filed: 1982-01-06
Abstract: PURPOSE:To increase tracking sensitivity and at the same time to reduce offset errors, by obtaining a tracking signal by performing the synchronous rectification at a pit edge after setting the accuracy of the synchronizing time at <=10% the time required to cross the pit. CONSTITUTION:The pits on an optical disk are shown by 40-48 in a figure, and a spot locus is shown by 7 for the laser which irradiated the pit. A sum signal (RF signal) is minimum at the center of each information groove; while a difference signal (DF signal) has the maximum or minimum value at the edge of each information groove. In terms of time series, the signal DF has a phase delay of 90 deg. to the signal RF at one side of a track and at the same time has a phase advance of 90 deg. at the other side of the track. A tracking signal is obtained from these RF and DF signals by setting the timing of the synchronous rectification at a pit edge with accuracy equivalent to <=10% the time required for a light spot to cross a recording pit. This process ensures the stable reading of information for both an audio disk and a video disk.

Title: Optical filter and optical shutter
Inventor: FUKUSHIMA SHO
IPC: G02B5/28
Filed: 1999-01-05
Abstract: PROBLEM TO BE SOLVED: To obtain a filter capable of largely shifting the wavelength area of fetched light by providing an actuator changing a distance between 1st and 2nd substrates and shifting the wavelength area of emitted light. SOLUTION: Plural PZTs 15 are arranged as the actuator between the substrates 11 and 12. By applying voltage to the PZT 15 from a driving circuit 16 by a control circuit 17, the PZT 15 is extended toward both ends by an amount in accordance with the voltage, so that a distance D between the substrates 11 and 12 is changed. Incident light beams made parallel beams are given to the filter 1 from an oblique direction so as to obtain a specified incident angle θwith respect to reflection films 13 and 14, and the light beams having the various number of reflecting times are included in the light beams transmitted through the film 14, whereby the light beams interfere with each other. By such interference, in what wavelength the phases of the light beams coincide depends on the distance D between the substrates 11 and 12.  Therefore, when the distance D between the substrates 11 and 12 is changed, a wavelength region where the intensity of the emitted light beam is high is shifted.

Title: Oscillator
Inventor: TSUNASHIMA KENICHI
IPC: H03B5/32
Filed: 1982-01-05
Abstract: PURPOSE:To select an oscillating element, by connecting the oscillating element to each of a plurality of emitter followers and flowing a current to the emitter follower selectively. CONSTITUTION:When a switch 36 is selected to the position of contact (a), a transistor (TR)37 is nonconductive and a TR38 is conductive. Then, a TR28 is conductive. As a result, since the base-to-emitter junction of a TR26 forming the emitter follower circuit is biased reversely by a resistor 39, no signal is transmitted. A TR40 is nonconductive, a TR29 is conductive and a TR27 acts like the emitter follower. The oscillating output is given to a crystal 35 through the TR27 and is oscillated in the oscillation frequency determined by a crystal 35. Thus, in using one set of voltage controlled oscillator for a color synchronized circuit of PAL and NTSC system, the oscillating circuit is simplified.

Title: Manufacture of molded coal for manufacture of coke for blast furnace
Inventor: ISOZAKI HIDEO
IPC: C10B53/08
Filed: 1980-01-10
Abstract: PURPOSE: To obtain a molded coal of a high density simply in a high yield with less pulverizing rate by a method in which a molded coal for charging in a coke oven, containing a weakly caking coal, is molded using a water-soluble powdery binder at ordinary temperature by means of a molding machine installed on the ground.  
     CONSTITUTION: A molded coal for charging in coke oven, containing a weakly caking coal, is mixed with a water-soluble powdery binder in an proportion of 0.1W2pts.wt. on the basis of 100pts.wt. the molded coal and then made into molded coal at the ordinary temperature for the manufacture of coke for blast furnace by means of a molding machine installed on the ground. Thus, the bulk density of the molded coal is increased because of partial breakdown while being passed through the junctions of belt conveyer and chute during the transfer to the coke oven. Also, the water-soluble powdery binder to be added is easy to handle, and also the molding operation is easy because the molding machine installed on the ground is used. Accordingly, a molded coal having a high bulk density and less sulfur content as well as a high flexible respondence to more or less increased moisture can be obtained with a lessened pulverizing rate in a high yield even for mlding coal of a grain size of 25mm or more.
