Patent JP-H02186523-A (JP)
Title: Operating handle
Inventor: TAKEUCHI KAGEHARU
IPC: H01H73/02
Filed: 1989-01-13
Abstract: PURPOSE:To improve workability of assembly by making it unnecessary to mount a spring in a streched-out condition with a torsion spring as a spring for energizing a turning force (or a restoring force) of an operating lever. CONSTITUTION:The linear arm of a torsion spring 52 is applied to a shaft-like projection 51 of a boss integrally formed with an operating lever 50 to receive an energizing force of the torsion spring. A spring holding means 53a consists of a pin set on a base plate 53 like a tree, a bend made by bending a part of the base plate 53 or a boss integrally formed with a base member, and the spiral coil of the torsion spring 52 is fitted to the spring holding means 53 such that the torsion spring 52 can be held. The torsion spring 52 is, therefore, mounted by fitting the spiral coil of the torsion spring 52 to the holding means 53a and applying the two linear arms to the projection of the operating lever 50, respectively. Thereby, it becomes unnecessary to mount the spring 52 in such a condition as it is stretched out with the result that the assembly workability can be improved.

Title: Fluidic flowmeter
Inventor: IECHI HIROYUKI
IPC: G01F1/20
Filed: 1999-01-14
Abstract: PROBLEM TO BE SOLVED: To measure flow rate from a flow rate of zero to a high range of flow rates. SOLUTION: In this fluidic flowmeter 11, a fluid to be ejected is ejected from the orifice of a nozzle 15 and a part of a jet which is the flow of the fluid to be ejected is reversed along a return flow passage R within a fluidic vibrating element 16 and converted to a return flow, which imparts energy to a jet that is newly ejected form the nozzle 15; flow rate is calculated on the basis of the frequency of fluid vibration caused thereby. The shape of the focus of a radial function is used as the shape of the return flow passage R. Such a return flow passage R allows fluid to flow smoothly enough to prevent the separation of a boundary layer and thus avoid generation of unnecessary vortices. This prevents noises from being generated by pressure waves caused by fluidic vibrations and measuring accuracy from decreasing as the result of energy losses.

Title: Gain control circuit
Inventor: NAKAMURA NORIO
IPC: G11B20/10
Filed: 1987-01-19
Abstract: PURPOSE:To eliminate the information for automatic gain control circuit which is included in the servo information of a magnetic disk by providing a means to detect the gain to an automatic gain control circuit. CONSTITUTION:A switcher 92 selects the fixed gain mode/automatic gain mode in which the amplitude of a read signal read from a disk by a variable gain device 90 is compared with the amplitude of a prescribed set voltage in an amplitude detector 91 and a difference signal is supplied, and a gain in the selected mode is converted to a voltage or a current is outputted from the switcher 92. This output is supplied to a control voltage generator 93 where a gain setting voltage is generated and it is supplied to a gain device 90 and a gain detector 94. In the mean time, the detector 94 detects the gain in the gain device 90 by means of equalization, and the detected output is supplied to the generator 93. Thus the gain of the gain device 90 is stably controlled based on the difference between its own gain and the set gain. As a result, the information to control the stability of an automatic gain control circuit included in a servo information of a magnetic disk is made unnecessary, hence the storage capacity of a magnetic disk device can virtually be enhanced.

Title: Semiconductor memory device
Inventor: ANAMI KENJI
IPC: H01L27/10
Filed: 1986-01-16
Abstract: PURPOSE:To reduce the power consumption of a memory cell by turning on and access transistor (TR) of a unit memory cell intermittently in the unit of row or plural rows of the memory matrix cell when an address signal changes. CONSTITUTION:An address counter 23 generates a row address signal independently of external row address signal X0-Xn by using a word line control signal phiX as a clock. Since a selector 24 fetches an output of a row address buffer 11 while a new data representing the cycle start is read, the address data designated by the signals X0-Xn is outputted and when the signal phiX rises, the output of the counter 23 is fetched and the signal on a word line goes to '1' for the row designated by the counter 23 and only one row of access TRs 5a, 5b is made conductive. Then every time the signal phiX enters as a clock, the output of the counter 23 is increased so as to make all rows conductive sequentially. Thus, the supplement of the electric charge from bit lines 3a, 3b is for one row only so as to reduce the power consumption.

Filed: 1978-01-31
Abstract: PURPOSE: To eliminate an operational malfunction of the negative pressure on-off valve for return flow of the exhaust gas, by releasing a phenomenon of the sticking status of the negative pressure on-off valve when starting the engine.  
     CONSTITUTION: A big negative pressure port 11, provided in an air intake pipe 10 afterward from a throttle valve 7, is linked to a negative pressure chamber 3 of the negative pressure on-off valve 2 through a solenoid on-off valve 12. And to the solenoid on-off valve 12, are being connected a starter switch 13 and a timer relay 14. And for starting the engine, with the starter switch 13 closed, a current flows in the solenoid on-off valve 12 for a period of several seconds by the timer relay 14, to open the solenoid on-off valve 12. During this period, a big negative pressure, at the big negative pressure port 11, works to the negative pressure chamber 3 of the negative pressure on-off valve 2, to lift up a valve 4 by a strong force,  releasing the sticking phenomenon caused during not in operation of the engine.  Thus if once released the sticking phenomenon, a smoothness is provided in the  movement thereafter, accordingly, a control of the negative pressure on-off valve  2 comes to be capable by even a weak negative pressure at a negative pressure port 8.
