Title: Timing specification verification system for logic circuit
Inventor: KAWACHI TOSHIHIKO
IPC: G01R31/319
Filed: 1991-07-12
Abstract: PURPOSE:To ease the restriction on usage by setting the direction of the change of a logic value to be propagated to the input terminal of a function block, retrieving a propagation path, obtaining the delay value of the propagation path while accumulating the delay time of each block, and setting the logic value of the external input terminal so as to propagate the delay time of each block. CONSTITUTION:When a code 'R' in the change direction of the logic value is set to a T22 for clock input, a logic value change code of the output terminal of a HAND gate A4 becomes 'R'. Accordingly, the logic value change code of the output terminal of the HAND gate A4 becomes 'R'. For this purpose, L13 or L14 may be the code 'F'. When a code 'F' is set to a signal line L13, the logic value of the signal line L14 becomes '1' so as to propagate the change of the signal to the output terminal of the HAND gate A4. The delay value takes the output rise delay time 3ns of the NAND gate A4, to be stored for the calculation for the propagation path delay value. The propagation path retrieval reaches terminals T5 and T6 for external input, and the delay of the propagation path becomes 3ns stored in advance.

Title: Liquid crystal electro-optical device
Inventor: YAZAKI MINORU
IPC: G02F1/1337
Filed: 1993-07-12
Abstract: PURPOSE:To improve orientation characteristics by applying rubbing treatment only to one of substrates, regarding a liquid crystal electro-optical device where an orientation film is formed on electrodes on the inner sides of two opposite substrates, and smetic liquid crystal is clamped between the two substrates. CONSTITUTION:A transparent electrode 22 is formed on the inner side of an upper glass substrate 20, and an orientation treated layer 23 coated with polyvinyl alcohol is applied to the electrode 22 at a rubbing process. Also, another transparent electrode 22 formed on the inner side of a lower glass substrate 21 is coated with a vertical treatment material of fluorocarbon cation, thereby forming an orientation treated layer 24. Then, the upper and lower glass substrates 20 and 21 are pasted top each other at the prescribed gap via a spacer 25, and smectic liquid crystal is sealed into the gap, thereby forming a liquid crystal layer 26. In this case, the thickness of the layer 23 should preferably be between 200 A and 10,000 A. According to this construction, the orientation treatment method is different between the opposite substrates 20 and 21, and only one substrate is subjected to the rubbing treatment, thereby eliminating improper orientation and ensuring quick switching operation.

Title: Complementary metal oxide semiconductor integrated circuit device
Inventor: HARA HIROSHI
IPC: H01L27/08
Filed: 1982-09-30
Abstract: PURPOSE:To prevent a latch-up phenomenon effectively by diffusing and forming high impurity concentration layers of the same conduction type as each substrate region, in which CMOS transistors are formed, to each substrate region up to sections deeper than sources while the high impurity concentration layers are brought into contact with the sources. CONSTITUTION:The p<+> layer 20 is formed brought into contact with the source 18 of the n channel MOS transistor in diffusion depth sufficiently deeper than the source 18. The p<+> layer 20 is connected to VSS in common with the source 18. The n<+> layer 16 is also formed brought into contact with the source 14 on the p channel MOS transistor side in diffusion depth sufficiently deeper than the source 14. The n<+> layer 16 is connected to VDD in common with the source 14. Consequently, even when hole currents are generated by an intense field effect in the vicinity of the drain of the n channel MOS transistor in a p well 12, the hole currents are extracted effectively to the outside by the p<+> layer 20. Electronic currents generated in the substrate are also extracted effectively to the outside by the n<+> layer 16 in the same manner on the p channel MOS transistor side. Accordingly, a parasitic bipolar transistor is not turned ON, and the latch-up phenomenon is prevented positively.

Title: Controller for brushless motor
Inventor: OI SHINICHI
IPC: H02P6/12
Filed: 1992-06-05
Abstract: PURPOSE:To provide a controller for operating a brushless motor at low noise while preventing overheat positively. CONSTITUTION:A temperature-sensitive element 65 is built in a current supply circuit 6 for Hall elements H1-H3. Resistance of the temperature-sensitive element 65 increases as the temperature of a brushless motor 1 rises. Consequently, base voltage of a transistor 61 increases thus increasing current supply to the Hall elements H1-H3. Rising point of time of the outputs from control circuits CP1-CP3 is thereby advanced thus advancing conduction timing of stator coils L1-L3 through a conduction timing control means 3. As a result, power efficiency is enhanced although noise is increased and the brushless motor is protected against overheat. When the temperature of the brushless motor drops, conduction timing is delayed due to function of the temperature-sensitive element and low noise operation takes place again. The temperature-sensitive element may be built in a threshold voltage generating circuit 5.

Title: Winch for elevator
Inventor: IIDA YASUMASA
IPC: B66D1/22
Filed: 1989-07-04
Abstract: PURPOSE:To reduce the size of a joining member and prevent oil leakage by employing a holding section formed integrally with a lower gear box at a contact portion either on a drive rope wheel side of a gear box or on the opposite side according to the direction in which a suspending weight is exerted, and disposing a shaft passing through the holding section. CONSTITUTION:A shaft 2 of an elevator winch passes through a holding section 11 of a lower gear box 4 and extends outside. Therefore, a force F1 caused with a suspending weight W is borne with the holding section 11 and is not exerted to an upper gear box 5. Therefore, bolt 6 and nut 7 need not be made stronger and larger. No gap is produced between the top and bottom surfaces 4a, 5a of the lower end upper gear boxes 4, 5, eliminating the possibility of oil leakage. Because the upper gear box 5 is not a strength member, weight reduction is possible.
