Inventor: KASHIWAGI TAKASHI
IPC: H04L27/233
Filed: 1990-09-07
Abstract: PURPOSE:To eliminate the limit on a pulse width of a reset pulse by allowing each of integration circuits to integrate alternately each one symbol of a discriminator output for an integration time being a time equivalent to one symbol or over and less than two symbols and short-circuiting an output of the discriminator with a reset pulse in which the sum of its pulse width and the integration time is within two symbols. CONSTITUTION:Integration circuits 51, 52 integrate respectively one symbol of an output of a discriminator 3 being a pi/4 shift QPSK pi/4 shift phase modulation signal alternately for an integration time equivalent to one symbol or over and less than two symbols and short-circuits an output of the discriminator by using a reset pulse in which the sum of its pulse width and the integration time is within two symbols from reset pulse generating circuits 61, 62 for a 2-symbol period. A selection circuit 10 selects alternately one symbol each of a transmission data recovered from code recovery circuits 81, 82 corresponding to a phase change based on the result of comparison between an output of each integration circuit and a prescribed threshold level so as to eliminate the limit on the pulse width of the reset pulse.

Abstract: PROBLEM TO BE SOLVED: To enhance car security against theft in simple structure by laying out an actuator on the lower side of a bulged area into which a striker intrudes and providing a sub-plate which covers this actuator. SOLUTION: When a car is key-operated and locked during parking time, if someone tries to break mischievously a lock device 1 by inserting some tool from outside a door, an actuator 23 is substantially covered with a back plate and a sub-plate 52, which does not allow the access of other tools except for only part of an open lever 30 and part of a key lever 35, the tip of the other end of a ratchet lever 24 and an inner lever 46. Even when the open lever is turned with some tool, it will be impossible to unlock in a locked state. Even if the key lever is turned with the tool, nothing but for a key lever will be operable even if the key lever is turned. Even if the ratchet lever or the inner lever is forced to turn with the tool, the tool may be guided to the projection in a riser area of the back plate and a rib so that it may be escaped.  Even if the ratchet or a ratchet lever is turned with the tool from outside. It will be impossible to push downward or turn, since their upper part and the outside area are surrounded with the wall.

Title: Motor drive control circuit
Inventor: HAYASHI KAZUOKU
IPC: H02P3/08
Filed: 1997-09-03
Abstract: PROBLEM TO BE SOLVED: To provide a motor drive control circuit which can surely control the drive of a motor. SOLUTION: In a motor drive control circuit, a PTC element 4 provided with heating radiating bodies (heat radiating plates 5 and solder) is used as a breaking means. Since the heat radiating bodies 5 absorb and discharge the internal temperature of the main body 40 of the PTC element 4 through lead wires 41, the internal temperature of the main body 40 of the element 4 can be lowered quickly and sufficiently. Therefore, the drive of the motor can be controlled surely even when the motor is continuously driven.

Title: Memory circuit
Inventor: YAMAZAKI TAKASHI
IPC: G06F12/16
Filed: 1987-09-22
Abstract: PURPOSE:To secure the normal processing until the next trouble occurs by changing the polarity of a memory cell and loading a program again in case the memory cell has a bit stack fault. CONSTITUTION:The input is supplied to a memory through an input terminal containing no inverter of a double input selecting AND-OR circuit 19 containing a single side inverter before a fuse 21 is fused. At the same time, the output is delivered from the memory through an input terminal containing no inverter of a double input selecting AND-OR circuit 20 containing single side inverter. In case the memory has a bit stack fault, the fuse 21 is externally fused. Thus the input and the output of the memory are carried out via the input terminals containing inverters of both circuits 19 and 20. Under such conditions, a program is loaded again so that the bit stack fault can be masked in terms of the processing.

Title: Diaphragm device
Inventor: KAI FUTOSHI
IPC: G03B9/02
Filed: 1992-09-08
Abstract: PURPOSE:To accurately control the position of a stop blade by changing the speed of a stepping motor in accordance with the opening of the stop blade. CONSTITUTION:The stepping motor for driving the stop blade is provided, and variable speed driving where the stepping motor is driven in a state where the speed from the time of opening the stop blade to the time of closing it is not set to constant speed but to speed in accordance with a stop value is performed. Namely, whether the stop blade is moved in an opening direction or a closing direction is discriminated based on a present light quantity. Then, according to the stop value, the stepping motor is driven by lectangular wave voltage within the opening range equal to or above a certain stop value, and driven by sinusoidal microstep-waveform driving voltage within the opening range equal to or under the stop value. That is, in the case of shifting to a minimum aperture state, the stepping motor is controlled to execute microstepping action finer than ordinary stepping action. Therefore, resolution in the case of the minimum aperture is improved.
