Title: Cell stack of fuel cell
Inventor: OOSHITA IKUTO
IPC: H01M8/24
Filed: 1982-03-25
Abstract: PURPOSE:To improve the output characteristics by inserting cushion members between rigid plates and bipolar plates at both ends of a cell laminated body so as to absorb a slight camber of the bipolar plates and to unify the surface pressure applied to each unit cell. CONSTITUTION:Cushion members 5 made of a compound material of carbon powder and paper or fiber mat are inserted between bipolar plates 2 and cooling plates 4 at upper and lower ends of a cell laminated body 3. The bipolar plates 2 and rigid plates such as the cooling plates 4 arranged at upper and lower ends can be tightened and assembled in complete contact with each other even if a slight camber is present on the sintered mold of the bipolar plates 2. The distribution of surface pressures applied to electrodes of individual unit cells 1 is widely improved by tightening the cell stack.

IPC: B23Q35/48
Filed: 1987-03-03
Abstract: PURPOSE:To put pick feed into practice with certainly, by dividing the whole circumference into two areas with a straight line connecting the specified turning angle position and the turning center of a model, and performing no pick feed at the time of admission from the first to the second area of a stylus, but performing it at the time of the admission from the second to the first area the other way. CONSTITUTION:The whole circumference of a model MDL is divided into two parts, or both areas AI and AII by a straight line connecting a limit line LL' being specified by the specified turning angle thetaL, that is, a point PL of the angle thetaL to a turning center OM of the model MDL, and an area where a stylus ST exists in the initial stage at time of starting of rotor copying is set down to the first area AI. And, when the stylus ST is relatively rotated to the model MDL by the rotor copying, no pick feed takes place when the stylus ST advances into the second area AII from the first area AI, but the pick feed is performed when the stylus advances into the first area AI from the second area AII. Thus, the pick feed can be done per rotation surely.

Filed: 1979-04-19
Abstract: PURPOSE:To improve the signal discrimination characteristic and stability of the output for switching, by operating a switching matrix circuit by the output of a reed filter and the output signal of an LPF. CONSTITUTION:The switching signal applied to input terminal 1 is detected by AM detector 2, and one is input to comparator 4a through reed filter 9, and the level of the output signal is compared with a reference signal; and the other is input to level comparator 4b through LPF10 and is compared with a reference level. Switching matrix circuit 5 is operated by outputs of comparators 4a and 4b, so that prescribed mode switching can be performed. That is, the output mode is discriminated by combination of presence and absence of two filter outputs. Here, since response of the LPF is superior in comparison with the reed filter, stability of the output for switching to the monaural mode is improved. By the simple circuit constitution like this, characteistic of signal discrimination and stability of the output for mode switching can be improved.

IPC: G11B19/00
Filed: 1986-03-06
Abstract: PURPOSE:To reduce power consumption by providing a function which receives a motor start signal, transmits the signal to a step motor according to a preset sequence and returns a magnetic head to a reference position. CONSTITUTION:If the current position of the magnetic head is not a reference once, it is recognized to be outer than the reference position.

If the current position is inner, one pulse is transmitted to move the magnetic head outside. By repeating such recognition and transmission of pulses, the magnetic head can be returned to the reference position. Thus the function which causes a magnetic head drive part 2 to receive the motor start signal Son, to transmit the signal to a step motor STM 21 according to the preset sequence and to return the magnetic head to the reference position is added, whereby the drive power source of the STM can be cut at the time of standing by an input signal, and power that the STM consumes can be reduced.

Title: Data processor having pipe line processing mechanism
Inventor: MATSUO MASAHITO
IPC: G06F9/42
Filed: 1988-03-01
Abstract: PURPOSE:To attain a leading branching processing for a return destination address in the initial stage of a pipe line processing by providing a stack memory (PC stack) dedicated to a program counter, which stores only the return address of a subroutine call instruction. CONSTITUTION:The PC stack 46 which stores only the return destination address at the time of subroutine call is provided. When the subroutine call instruction is executed, the return destination address from a subroutine is pushed by the PC stack 46 in an E (execution) stage. When the subroutine return instruction is decoded, the leading branching processing (pre-return) is executed to an address in a stack top of the PC stack 46 in a D (decode) stage. In the D stage being the initial stage of the pipe line, the disturbance of the pipe line due to the execution of the subroutine return instruction can be reduced for executing the branching processing. Thus, the branching processing of the subroutine return instruction can be executed prior to the processing in the instruction execution stage, and the overhead of the pipe line processing by the execution of the subroutine instruction is reduced.
