Title: Receptacle type electrical contact
Inventor: GRUBBS JIMMY GLENN
IPC: H01R13/11
Filed: 1999-08-31
Abstract: PROBLEM TO BE SOLVED: To provide a receptacle type electrical contact of a fixed total length capable of having various spring forces in spite of use of a different plating material. SOLUTION: A receptacle type electrical contact 30 has asymmetric contact beams 46 facing to each other, between which a terminal reception part is partitioned. The asymmetric contact beams 46 facing to each other can have various widths to generate an appropriate spring force for a selected plating material with a total length of the receptacle type contact 30 kept the same total length as a contact manufactured by use of a different plating material. Although the receptacle type contact 30 allows a change of a spring force with its size limited, the receptacle type contact 30 hardly breaks during bending.

Filed: 1987-09-30
Abstract: PURPOSE:To keep the input power to the minimum required by providing a detecting means detecting the half-wave discharge of a discharge lamp and providing a control means controlling the discharge lamp at the dim lighting state in response to this detection output. CONSTITUTION:When a discharge lamp 3 is half-wave-discharged at the terminal stage of its life, the detection current through a serial circuit 13 is increased, the detection input level of the comparator 15 of a detecting means 4 rises, and the comparator 15 generates an output.

The input increase is suppressed, and a lighting device is prevented from being made large-sized. An abnormality of the discharge lamp 3 is reported at the time of the dim lighting state, the room is not made dark because of the dim lighting state, and the lamp can be easily replaced.

Filed: 1999-08-31
Abstract: PROBLEM TO BE SOLVED: To realize a high write throughput by repeating a write verify operation until writing to all memory cells corresponding to a data level of a predetermined number finishes. SOLUTION: A write bias is applied to write to a memory cell 1 which stores data of 2 bits per cell. Subsequently, the cell is verified with the use of data of a data hold circuit 6. A corresponding judge circuit 4 is first activated by selecting the memory cell 1 having a write target of a first state. Then, a word line WL of the memory cell is set to a first state verify level, and the verified result of the first state is held into the judge circuit 4 corresponding to the first state write memory cell 1. Connecting a bit line BL to the judge circuit 4 is carried out with the use of data of the data hold circuit 4. When the verified results from the first state through the third state are all obtained, batch judgment is carried out before writing to an insufficiently written memory cell.

Filed: 1998-09-01
Abstract: PROBLEM TO BE SOLVED: To obtain an ordinary color at the time of turning off, to obtain a pure functional color at the time of turning on, and to make the functional color to be seen from any direction. SOLUTION: At the time of turning off, an ordinary color of a chromatic color opaque part 8 inside of an inner lens 6 diffused by a diffusion action of a diffusion optical element group 7 outside of the inner lens 6 can be obtained. At the time of turning on, a colored light from a light source bulb 4, which reflects on a reflection surface 5 and passes through a color cap 11, diffuses and transmits the inner lens 6, thereby obtaining a red functional color of the color cap 11. Of all colored lights, the lights which have reached the chromatic color opaque part 8 are not emitted from the inner lens 6, and the lights which have reached a part having no chromatic color opaque part 8 are emitted from the inner lens 6, so that only colored lights which have diffuse and transmitted the inner lens 6 are obtained as the functional color, and a pure functional color can be obtained.  By changing the size of the plural chromatic color opaque parts 8 and the focal length of the diffusion optical element group 7, the functional color is allowed to be seen from any direction.

Title: Constant voltage driving circuit
Inventor: YAMAZAKI TADANORI
IPC: H03F3/347
Filed: 1987-09-29
Abstract: PURPOSE:To eliminate a reference voltage source, to reduce the chip area and to obtain a circuit to be suitable for monolithic construction by using a differential amplifier having an offset in a circuit for detecting load fluctuations. CONSTITUTION:This circuit equips a differential amplifier 1 to be connected to a voltage follower to execute a constant voltage driving and a differential amplifier 2 to have the off-set in an input characteristic. In this constitution, when a load is small, a large current is passed from an output terminal out 1 and an electric potential VA' of an A' point is kept to be equal to an electric potential VIN4 to be added to an input terminal. Thus, when the value of the current passed from the terminal out 1 IL, the electric potential VA at a point A becomes as given by the equation (shown in the figure). The differential amplifier 2 outputs a high level at VA-VA'>Vof and a low level at VA-VA'< Vof to an output terminal out 2.

IPC: B41N3/00
Filed: 1990-09-19
Abstract: PURPOSE:To stabilize a surface treatment process by monitoring and controlling the operation of an electrodialytic cell in order to hold the concn. of the acid in a waste solution to a predetermined value or more. CONSTITUTION:A regeneration solution from which an aluminum ion is removed is mixed with supplied fresh water and a supplied raw treatment solution in a supply tank and the resulting solution mixture is returned to a treatment solution tank 7 through piping 22 by a pump 12 or refluxed to an electrodialytic cell through piping 14. By this method, the concn. of the aluminum ion of the circulating treatment solution in the treatment solution tank 7 is lowered and controlled to constant predetermined concn. to supply the treatment solution to a header 4 by a pump 5. The concn. of nitric acid on the side of a waste solution is measured by a conductivity meter 23. When the concn. of nitric acid approaches zero, aluminum hydroxide is precipitated to be bonded to an ion exchange membrane. In order to prevent this phenomenon, the conductivity meter 23 is monitored and a conductivity value is fed back to a rectifier 24 and an automatic valve 25 to perform control so as not to bring the concn. of nitric acid to zero.

Filed: 1994-09-14
Abstract: PURPOSE: To keep the balance quickly in response to the displacement of a load by providing a sensor valve for sensing the movement of a piston of an air cylinder caused by a little displacement of load to be balanced. CONSTITUTION: When a load supported on a wire 13 is lifted up, a piston 4 is moved to the right, that is, in the direction of an arrow A through a ball screw 1 so that a valve 17b of a sensor valve 17 is still closed, and a valve 17a is opened. At that time, the valve 17a is opened by a slight movement in the direction of the arrow A, for example, the movement of 0.1mm, so that pressurized air from a pressure source P is introduced into the inside of an air cylinder 2. The pressurized air adjusted by a regulator 10 is introduced into the air cylinder 2 through the valve 17b or through another route by a pipe 8a. While the piston 4 is moved, the state that one valve of the sensor valve is opened can be kept.

Title: Dc stabilized power supply circuit
Inventor: FUWA HIROMASA
IPC: H02M3/155
Filed: 1992-09-17
Abstract: PURPOSE:To reduce the number of components by simplifying the configuration of a DC stabilized power supply circuit. CONSTITUTION:The output voltage applied to a load 10 is detected as the middle-point voltage of two resistors 20 by a signal 100. An output voltage detection circuit 30 feeds an oscillation drive signal 106 to an oscillation circuit 32 when the potential indicated by the signal 100 is reduced. The oscillation operation of the oscillation circuit 32 is directly controlled by the oscillation drive signal 106 and an oscillation signal 104 is directly given to a switching transistor 18. When the switching transistor 18 performs switching operation, an output voltage is boosted. When the output voltage exceeds a certain voltage, oscillation stops and the operation of the switching transistor 18 also stops.
