Title: Manufacture of circuit board with thin-film capacitor
Inventor: HAYAKAWA TOSHITAKA
IPC: H01G4/33
Filed: 1998-05-15
Abstract: PROBLEM TO BE SOLVED: To obtain good characteristics in respective capacitance ranges with a few number of steps by conducting a metal thin-film forming step for anodizing by specific number of times, and individually executing the steps of anodizing the metal film to form a dielectric layer at least specific type or more of large and small capacitance by respective capacitance ranges. SOLUTION: This method for manufacturing a circuit board with a thin film capacitor comprises the steps of forming a lower electrode 12 for a large capacitance capacitor and a lower electrode 15 for a small capacitance capacitor, then sputtering tantalum on exposed parts of the electrodes 12, 15 and a titanium thin film layer 3 to form tantalum thin film layer 16, thereafter anodizing the layer 16 to form a dielectric layer 21 for the large capacitance capacitor, and then anodizing a dielectric layer 26 for the large capacitance capacitor to form it. According to the method, since suitable anodizing voltages are sequentially applied individually at the capacitance ranges of two or more types of at least large and small capacitance and anodized, the respective capacitance ranges can be formed accurately.  Furthermore, the number of sputtering times is reduced to once, thereby reducing the number of the steps.

Title: Flat type fuel cell
Inventor: MURATA ATSUSHI
IPC: H01M8/12
Filed: 1999-05-13
Abstract: PROBLEM TO BE SOLVED: To promote an electrochemical reaction by extending and opening each termination part used as an oxidizer gas introduction port of an oxidizer gas passage channel so as to tilt toward the circumferential surface of a separator. SOLUTION: A termination part 30A of each forward passage 30a used as an oxidizer gas introduction port of an oxidizer gas passage channel 30 is so extended and opened as to tilt toward the circumferential surface 31a of a separator 31. That is, the termination part 30A does not have any discontinuous point such as a bent position bent at a right angle, but forms a passage gradually approaching the circumferential surface 31a of the separator 31 by continuing to the main part of the forward passage 30a so as to easily introduce the oxidizer gas from the circumference. The oblique line part of the separator 31 comes into surface contact with an electrolyte plate, so that the separator forms a closed cross-section together with it to compose the oxidizer gas passage channel 30.  By virtue of this structure, the introduction of the oxidizer gas around a layered product is facilitated and thereby, the flow rate of the oxidizer gas flowing in the oxidizer gas passage channel 30 can be increased.

Title: Running power transmission gear for tractor
Inventor: KATAYAMA NOZOMI
IPC: B60K23/08
Filed: 1989-05-26
Abstract: PURPOSE:To facilitate turning as well as to concurrently enable a four wheel drive condition to be maintained at all times by providing a control mechanism which controls an automatic switch-over means automatically engaging/disengaging power transmission to a front wheel power transmission shaft based on the running speed of rear wheels, to be in an engaged condition. CONSTITUTION:Power is transmitted to a driven body 37 from the trailing end power transmission shaft 29 of a charge gear mechanism via the spline shaft 30 of an outer package, the sliding cam 39 of a drive body 41, the sliding cam 39 of a slider 40 and both of clutch pawls 36, and is transmitted to a front wheel input shaft via a driven shaft 35. When the braking operation of one side rear wheel forces the ground running speed of the other side rear wheel to be doubled at the time of turning a tractor, front wheels are pushed so as to be advanced, this thereby permits a gap to be made between the driven surface of the sliding cam 39 of the slider 40 and the drive surface of the sliding cam 39 of the drive body 41, and the clutch pawl 36 of the slider 40 comes off from the clutch pawl 36 of the driven body 37 with the slider 40 slid so that the front wheels are conditioned to no power transmission. When an arm 51 is locked at an afterward rotating position, the slider 40 can not be slid in a state that both of the clutch pawls 36 are meshed with each other, a four wheel drive condition can thereby be maintained at all times.

Title: Clutch device
Inventor: SATOU HIRONOBU
IPC: F16D13/20
Filed: 1982-08-02
Abstract: PURPOSE:To contrive simplification of assembly and reduction of a number of parts and to prevent a function of a clutch from deteriorating, by so constituting that a second component made of synthetic resin is pinched elastically in an elastic beam part formed, together with a first component in a body, of synthetic resin. CONSTITUTION:Four elastic beam parts 11 are formed of synthetic resin on the inner face of a driven gear 6 in a body and the elastic beam parts are made to possess a spring function. A zoom ring 4 is mounted on the driven gear 6 by making the zoom ring 4 hold by pinching by the elastic beam part 11 through repulsive force of the elastic beam part 11. As the driven gear 6 and the spring beam part 11 are formed in a body like this, a reduction of a number of parts and simplification of assembly can be realised. The external circumferential surface of the zoom ring is not scraped off by the spring beam part and preciseness of a function of a clutch does not deteriorate as both the spring beam part 11 and the zoom ring 4 are formed of synthetic resin.

Title: Write protecting system for asynchronous double buffer
Inventor: BABA AKIRA
IPC: G06F5/16
Filed: 1988-05-30
Abstract: PURPOSE:To output only settled data by providing a certain fixed delay time between write and read, and preventing the data in an unsettled condition from being written. CONSTITUTION:A first buffer register 1 stores the data to be inputted under the control of a write signal A. A second buffer 2 is serially connected to the register 1, controls the data stored into the register 1 by a write signal B, and stores and outputs them. An extending circuit 3 supervises data volume written into the register 1, and with the use of a generated EMPTY signal, outputs the signal which extends the fall of the EMPTY signal for the period of the fixed time. When the write signal A and the write signal B approach, a second AND 6 instructs the output stop of the data written into the register 2 by the output generated by means of the circuit 3. Thus, the data in the unsettled condition can be prevented from being written, and only the settled data can be outputted.

IPC: B60T8/20
Filed: 1979-10-18
Abstract: PURPOSE: To complement the shortage of the braking force of the whole car by a mechanism wherein the control of a slow rise at a bending point of the hydraulic pressure of a rear wheel brake hydraulic pressure system is released when the hydraulic pressure of another independent system causes failure.  
     CONSTITUTION: When a brake functions, a differential pressure switch 10 is turned ON when a brake hydraulic pressure system at the front wheel side expires, and an electromagnetic change-over valve 107 is excited regarldless of the deceleration of wheels. Thus, since a confining liquid chamber a 3  of a hydraulic pressure controller 9 is communicated with an input liquid chamber a 1  at all times and a controlling spring 104 is continuously increased in proportion to hydraulic pressure, a slow rise at a bending point of the hydraulic pressure of rear wheel brakes 6, 7 is not controlled.
