Title: Swing check valve
Inventor: OKURA RYOICHI
IPC: F16K15/03
Filed: 1996-04-12
Abstract: PROBLEM TO BE SOLVED: To prevent repetition of intermittent opening and closing of a valve element even when a flow rate passing through a valve is low by preventing the valve element and a valve seat from making contact with each other and providing a flow passage to intercouple a spot situated upper stream from a valve and a spot situated downstream therefrom. SOLUTION: A valve element 2 is attached to an arm 3 and connected to a valve casing 1 through a hinge pin 5. Thus, a valve element 2 and the arm 3 are movable around the hinge pin 5 serving as a fulcrum. An angle α, between a straight line passing through the center of gravity point of the valve element 2, containing the arm 3, formed during closing of a valve having the valve element adhered to a valve seat 4 and a straight line passing through the support point of the hinge pin 5 to support the arm 3 is formed in a spot situated upper stream of a flow of fluid along a vertical straight line passing through the support point of the hinge 5 to support the arm 3. Thus, even when a flow does not occur to fluid in a valve, the valve element 2 and the valve seat 4 are not adhered to each other and the valve is not closed.

Abstract: PURPOSE:To detect and correct positional deviation between alignment marks by a method wherein an alignment mark on a wafer and another on a mask are so patterned that their width is larger at a point farther from their centers and that the pattern on the wafer and that on the mask are so positioned that they cross each other. CONSTITUTION:Alignment marks are constituted of a pattern 11 on a wafer and a pattern 12 on a mask. Between the patterns 11 and 12, there is an overlap 13. The area of the overlap 13 registers its minimum when the center of the pattern 11 on the wafer and the center of the pattern 12 on the mask coincide. The area of the overlap 13 increases when the patterns 11 and 12 change their relative positions. The area that the overlap 13 occupies is detected by a detecting device, the pattern 12 on the mask is caused to move, for the minimization of the area the overlap 13 occupies for the correction of their positional difference.

Title: Data generating method and data generating device
Inventor: NOUZEN CHOSAKU
IPC: G11B20/12
Filed: 1998-04-03
Abstract: PROBLEM TO BE SOLVED: To enhance a random error correcting capability without lowering a format efficiency by reducing the number of synchronous patterns per unit data while enlarging a unit block to which a synchronous pattern is to be added and asssigning areas equivalent to the reduced number of synchronous patterns to additional check paritys. SOLUTION: Paritys are added to data blocks with 172 rows × 192 columns by applying Reed-Solomon product encodings to them. At first, 16-byte paritys are generated as outer sign paritys with respect to 192-byte data of respective columns. After encodings of outer signs are performed to all columns, 12-byte paritys are generated as inner sign paritys by performing encodings of respective row direction with respect to the data blocks and the outer signs. Thus, error correcting blocks with 184 rows × 208 columns are generated. Moreover, one synchronous block is generated by adding a 2-byte synchronous pattern at the leading of 184 bytes equivalent to one row. Error corrections being 6 symbols at the maximum is made possible by the 12-byte inner sign parity.

Title: Light reception circuit
Inventor: GOTO MASAHIRO
IPC: H03K17/78
Filed: 1988-04-15
Abstract: PURPOSE:To increase the maximum allowable quantity of light input by displacing the emitter resistor 7 of an emitter follower circuit in a light reception circuit by a constant current source 8 and keeping the collector current of the emitter follower circuit constant. CONSTITUTION:The emitter follower circuit is constituted without using the constant current source. And the cathode of a photodetector 1 is connected to the base input terminal of an emitter grounding circuit. Thereby, the output voltage V0 of the reception circuit is increased by light input. When the potential of the output of the the reception circuit is increased by the light input, the collector current IC4 and the base current IB4 of the emitter follower circuit as a buffer stage are increased, and the collector current IC3 which flows in the emitter grounding circuit as an amplifier stage is decreased. Therefore, in the light reception circuit, the emitter resistor of the emitter follower circuit is displaced by the constant current source 8, thereby, the collector current IC1 of the emitter follower circuit can be kept at a constant value I0. In such a way, in a range where the relation of equation is satisfied under an operating condition IC3>=0, the maximum value of the current Is of the photodetector 1 goes to a value larger than that in a circuit in Fig. 5, then, the maximum input current can be expanded.
