Title: Hydraulic speed change operating device for running vehicle
Inventor: KITAO YUICHI
IPC: B60K17/06
Filed: 1993-11-17
Abstract: PURPOSE:To enable a vehicle to travel at a condition of demagnetization by letting the direction switch-over valve of the hydraulic speed change operating device for a running vehicle be so constituted as to be furnished with a neutral position N, and also as to be capable of being manually operated at the time of demagnetization, and concurrently letting either one of a proportioning valve or the switch-over vale of a main speed change mechanism act as a reverse characteristic valve which feeds pressure oil at the time of demagnetization. CONSTITUTION:An electromagnetic direction switch-over valve 6 and a proportioning valve 7 are connected to the hydraulic clutches 19F and 19R of the forward/reverse switch-over mechanism 17 of a tractor, The direction switch-over valve 6 is furnished with a neutral position N, can make switch-over for feeding pressure oil to the hydraulic clutches when the valve is magnetized, the valve is returned to a neutral position N when it is de-magnetized, and switch-over can be manually made. The proportioning valve 7 can be conditioned to a state of clutch coupling with slipping, so that the aforesaid valve can be made use of as a main clutch. Four hydraulic (clutches for a main speed change mechanism are connected to an electromagnetic switch-over valve and the aforesaid valve acts as a reverse characteristic valve which allows hydraulic oil to be fed only for a first forward speed when it is demagnetized. When the electric system of the tractor fails, if the direction switch-over valve 6 is operated to either way of forward or reverse speed, pressure oil is fed to the hydraulic clutches 19F or 19R, so that the tractor can thereby travel.

Title: High-speed clutch
Inventor: TANIGUCHI KATSUHIKO
IPC: F16D13/46
Filed: 1987-11-17
Abstract: PURPOSE:To perform connection/disconnection of a clutch at a high speed in response to ON/OFF of electric power applied to a piezoelectric element by fixing one end of the piezoelectric element, on whose other end a clutch disk connectable/disconnectable to/from an input shaft side disk is provided, to an output shaft side disk. CONSTITUTION:One end of a piezoelectric element 5 is fixed to an output shaft side disk 4 fixed to one end of an output shaft 3, while the other end thereof is fixed to a clutch disk 6 opposing to an input shaft side disk 2 fixed to an input shaft 1. A plurality of springs 7 are installed between the clutch disk 6 and the output shaft side disk 4 to secure clutch action. When a voltage is applied to the piezoelectric element 5, the element 5 extends much while when it is not applied, the element shrinks. The piezoelectric element 5 extends/ shrinks in a short time by switching the applied voltage ON and OFF, while the clutch disk 6 can connect/disconnect in a short time to/from the input shaft side disk 2. Clutch operation can be carried out with high speed, accordingly.

Title: Coriolis mass flowmeter
Inventor: OSAWA NORIKAZU
IPC: G01F15/00
Filed: 1995-11-07
Abstract: PROBLEM TO BE SOLVED: To realize highly accurate stabilized measurement of flow rate and density by employing finely collected channels in a measuring tube thereby oscillating a fluid at a constant amplitude even when the mixing rate of bubble is high. SOLUTION: A partition 11 is provided in a measuring tube 1 to provide fine collected channels 12 in the tube. Since a bubble mixed in a fluid fully occupies the cross-sectional direction of channel 12 at high possibility to block each fine channel, collision, annexation and separation of bubble are retarded. Consequently, oscillation noise is reduced and fluctuation of output is suppressed even for a liquid having high bubble mixing rate thus reducing error in the measurement. Furthermore, resonant state can be sustained stably because the measuring tube 1 is sectioned finely to prevent useless collision or annexation of bubble. According to the invention, even a measuring liquid having high bubble mixing rate can be oscillated with a constant amplitude and highly accurate stabilized measurement of flow rate and density can be realized.

IPC: G11C17/00
Filed: 1990-10-26
Abstract: PURPOSE:To increase working speed by installing a circuit for switching currents flowing through P and N channel transistors at a sense amplifier output stage ON-OFF based on presence/absence of fine currents flowing through a memory cell to the sense amplifier output stage and equalizing current for outputting a high level and current for an output a low level. CONSTITUTION:A P channel transistor 22 added at the output stage of a sense amplifier uses the source of a P channel transistor 5 as a drain, employs supply voltage as a source, uses the drain of an N channel transistor 4 as a gate, and employs a node S6 as the gate of an N channel transistor 6 as the gate. The mutual conductance gm (P5) of the P channel transistor 5 is equalized to the mutual conductance gm (P15) of a P channel transistor 15 by the P channel transistor 22. Accordingly, a problem, in which the delay of a data output at a time when a memory cell is turned OFF results in the delay of a sense amplifier output, is solved, thus accelerating a data output time.
