Title: Static type ram
Inventor: IDE AKIRA
IPC: G11C11/34
Filed: 1985-02-20
Abstract: PURPOSE:To make the high-speed application of the information read operation, by detecting a back edge of a write pulse and recovering a write signal given to a common complementary data line. CONSTITUTION:A write pulse -(WE.CS) is reverted and delayed through the CMOS inverter circuits IV4-IV10, and this delay signal and the write pulse are input into a CMOS NAND gate circuit constituted by the FETQ40-43. In a back edge when the write pulse is changed from 'L' to 'H' by this, only in the portion of the delay time set a detection signal phi that possesses a pulse width of 'H' is formed, transmitted to the switches Q35 and Q36 through a CMOS circuit and an output circuit composed of a bipolar transistor, and a voltage VCD from a power circuit is transmitted to the common complementary data lines CD1 and -CD1. Therefore, each complementary data line is recovered to a bias voltage VCD at high speed, and a data line of 'L' is quickly made to 'H'.

Abstract: PURPOSE:To improve the throughput by maintaining the compatibility of an object. CONSTITUTION:When a system call is made by the object, it is decided whether or not the object is an old object (step S10). When so, an OS starts stack operation for emulation on the main memory (step S11). After the stack operation, a return to a user mode is made (step S12) and in the user mode, emulation by an old system call is performed (step S13). After the emulation, an interruption initiation code which is put in a user stack in advance is executed to initiate an interruption, and a supervisor mode is entered again to perform stack operation (step S14).

Title: Power drive/regenerative switching controlling method of commutatorless motor
Inventor: OKADA YASUHIKO
IPC: H02P6/08
Filed: 1983-02-28
Abstract: PURPOSE:To shorten the noncontrolled state period of a motor by shifting the set control lead angle at the timing corresponding to the 60 deg. of an electric angle of the motor when switching the motor from the power drive to regenerative or vice versa. CONSTITUTION:When a motor is shifted from power drive to regenerative or vice versa, a current throttle signal SIO is risen at the time when an operating mode switching command signal SCH falls to suppress the motor current SMI to zero. After the SIO is applied, 60 deg. interval signal SMN of electric angle is used as the switching signal of a power conversion element, the set control lead signal is shifted at a plurality of timings as a shifting line SB in response to the timing of 60 deg. to transfer from power drive to regenerative or vice versa, and the current throttle signal is falled after the completion. Accordingly, the noncontrolled state period of the motor is shortened, thereby switching without danger due to overcurrent.

Thereby, the N type and P type fused liquids 6, 7 are placed in contact with a substrate 4, sequentially. After liquid phae growth, the seal 18 is extended moving the rod to the right 8 and the boat can be pulled. According to this structure, when an apparatus is once set, the air does not leak into the quartz reaction tube 2 even while the quartz rods 8, 9 are moving and the rod moves smoothly since there is no sliding portion and thereby a motor can also be driven.

IPC: G01M3/04
Filed: 1984-02-21
Abstract: PURPOSE:To prevent the generation of dummy leakage, by emitting an alarm when leakage is generated in a lining container. CONSTITUTION:When leakage is generated from a lining plate 3, a leaked liquid is flowed into a gap 5 and subsequently flowed into a drain tank from piping 9 through leakage detecting piping 7 and a visual observation box 23. When inflow is succeeded and a liquid level rises to reach the detection level of a level switch 21, the level switch 21 is operated to emit an alarm toward a central control chamber and a solenoid value 14A is operated to open a pipeline to enable the overflow of water in the drain tank 10. When inflow is further succeeded and a liquid level rises to reach an overflow level, a liquid is thereafter overflowed in an amount corresponding to an inflow amount and, therefore, a liquid level becomes stable and overflow succeeds. The liquid in the drain tank 10 is discharged by manually opening a usually closed valve 13A as a part of leakage post-treatment.

Title: Fast accessing system for optical disk device
Inventor: WACHI SHIGEAKI
IPC: G11B7/085
Filed: 1987-02-16
Abstract: PURPOSE:To enable a tracking servo circuit to be closed at a time when speed goes to zero in relative travel speed, by providing a speed detecting means capable of detecting the relative speed between a track and an optical spot at the time of traversing in a state where almost no time delay is generated. CONSTITUTION:A signal CT-N from a comparator 11 is decreased according to the travel of an optical head 13 to which a jump command signal CT is inputted, and addressing to a targeted track can be obtained if the tracking servo can be closed at the time when it goes to zero. However, eccentricity >=100mum exists in a disk generally, and it is difficult to apply tracking servo at this time. Hereupon, the motion of a head 13 is controlled by returning a speed signal detected by a speed detection circuit 15 at the time when the displacement error signal CT-N outputted from the comparator 11 is decreased to the optical head 13 via a distributor 12, a coefficient circuit K1, and an adder 17. Thus, the switch SW of the circuit 10 is turned ON at the time when the speed signal goes to zero, and the tracking servo is locked immediately, then, fast access can be obtained.
