Title: Tracking servo pull-in device
Inventor: FUJIWARA YASUHIDE
IPC: G11B7/085
Filed: 1990-05-17
Abstract: PURPOSE:To suppress the displacement of a lens for optical pickup at a low level and to improve the accuracy of tracking control more than ever by detecting relative speed between an irradiation beam of light and a track, and performing the tracking control at the maximum relative speed. CONSTITUTION:A pulse shape on-track signal (a) representing the fact that an optical pickup part is located in the center of the track 1 is detected from a tracking error signal Tr by an on-track pulse detection circuit 2. A detected signal (a) is F/V-converted by an F/V converter 3, and a relative speed signal (b) representing the traverse speed of the optical pickup part on the track 1 can be obtained. An on-track signal output means 4 detects the peak value of the signal (b), and sets a voltage less by a constant value than the peak value as reference, and compares it with the signal (b), and binarizes it, then, a window signal (c) opened at the maximum traverse speed on the track 1 is generated. A tracking control start timing signal (d) at the maximum speed traversing the track 1 can be obtained. The driving control of a tracking control mechanism is started at the timing of the signal (d).

Title: Suprecooling control valve and refrigeration cycle
Inventor: IRITANI KUNIO
IPC: F25B41/06
Filed: 1994-06-09
Abstract: PURPOSE:To achieve the optimum supercooling in order to attain a nearly maximal cycle efficiency by a method wherein the degree of valve opening is controlled based on the difference between the inner pressure of one pressure chamber which varies according to the change of the temp. of the air sucked into a room condenser and the inner pressure of the other pressure chamber which varies according to the change of the temp. of the refrigerant at the outlet. CONSTITUTION:A valve body 225 is disposed downstream of a throttling hole 231 in the inner space of a valve housing 220 and a displacement is transmitted to a diaphragm 224 via a stopper 237 and a rod 239 connected thereto. A spring 226 is disposed between the valve body 225 and an adjusting screw 227 and acts to bias the valve body 225 in the direction of decrease of the opening degree of the throttling hole 231, i.e., the valve opening degree. Therefore, the valve body 225 is shifted into a position in which is attained a balance between the inner pressure of one pressure chamber 235 acting in the direction of increase of the opening degree of the throttling hole 231, the inner pressure of the other pressure chamber 236 acting in the direction of decrease of the opening degree of the throttling hole 231 and the biasing force of the spring 226.

Title: Data transmission equipment
Inventor: TSUCHIYA HIROSHI
IPC: H04L13/00
Filed: 1985-06-14
Abstract: PURPOSE:To attain data transfer with excellent efficiency even when a transmit ter not outputting a data of word unit is used by allowing a block number counter to detect a data block number stored in an FIFO memory according to an input side block end signal and an output block end signal. CONSTITUTION:The block number stored in the FIFO memory 11 stored in a block number counter 12 is managed by incrementing or decrementing the value by +1 or -1. When the block number is below the block accommodated number N, the input side 2-wire hand-shake signal line 5 is made effective by AND gates 14, 15. When the block number is over the block accommodated enable number zero, the output side 2-wire hand-shake signal line 7 is made effective by using AND gates 16, 17 and the data transmission between a receiver 3 and the FIFO memory 11 is attained. On the other hand, when the content of the result of incrementation by +1 reaches the block accommodated number N, the input side hand-shake signal 5 is made ineffective ty using the AND gates 14, 15.

Inventor: OOTA YUKINORI
IPC: H04M19/00
Filed: 1985-06-14
Abstract: PURPOSE:To detect grounding and inter-line contact with simple constitution by comparing an output voltage of a current voltage conversion means with two present threshold voltages. CONSTITUTION:A window type voltage comparator CMP having two different reference voltage sources Vref1, Vref2 is provided. If a terminal 4 is grounded, no current flows to a resistor R1b and a transistor (TR)Q3b is cut off.

IPC: G01R31/28
Filed: 1990-05-18
Abstract: PURPOSE:To eliminate the need for a special circuit such as a fault detection circuit by monitoring whether or not a consumed current caused when each moving device of the phased array antenna with a specific control signal is driven is deviated from a measured value in advance so as to detect the presence or absence of a fault of each phase shifter.

Then in the actual operation, a phase shift angle phi of the phase shifters 5a-5n is set to the specific phase shift angle by varying each phase shift control signal outputted periodically from the controller 1 so as to check whether or not the consumed current of each phase shifter is the specific consumed current and when the current is deviated from the specific consumed current, it is decided that the concerned phase shifter is abnormal, and a switch 8 of a switch circuit corresponding to the abnormal phase shifter is activated to terminate a distribution coupler 3 by a termination resistor 9.
