Title: Production of helical gear
Inventor: HOGUCHI TETSUYA
IPC: B21J5/12
Filed: 1998-04-20
Abstract: PROBLEM TO BE SOLVED: To make it possible to produce a gear having high accuracy by upsetting a blank with a die having a tooth profile for tooth profile formation which is broader than the tooth thickness size of the tooth profile to be produced and has a helix angle small in a pressurization direction, then shaping the tooth surface with a die having the tooth profile for tooth profile shaping meeting in the tooth thickness size and helix angle identical with each other. SOLUTION: The blank is first set in the first die and is pressurized by a first punch. The blank is then guided to the slope of the tooth profile and while the blank is rotated, the blank is pushed into a cavity. Accompanying this pushing action, a helical tooth profile 12 bulges at the circumference of the blank and a performed molding is formed. The helical tooth profile 12 is formed wider than the tooth thickness size of the tooth profile to be produced and larger in the helix angle of the tooth surface 13. Under fills 13 are generated at the front end of the surface pressed to the tooth profile and the rear end of the opposite surface thereof. When the performed molding is set in the second die and is pressurized by a second punch, the tooth profile surface is shaped and the finished product having the tooth profile extremely faithful to the desired shape is obtd.

Title: Method of regulating deflection of leaf spring in electromagnetic system fuel injection valve of internal combustion engine
Inventor: SHIMIZU KEIZOU
IPC: F02M61/16
Filed: 1983-06-21
Abstract: PURPOSE:To stabilize the movement of a valve body to eliminate the fluctuation of flow by regulating the distance between a position in which a holder is supported and a position in which the valve body bears against a leaf spring to set the deflection of the leaf spring larger than the lift of the valve body. CONSTITUTION:Fuel is adapted to flow through a gap between a valve body 2 and valve seat 4 of a fuel injection valve. By plastically transforming a holder 14 in the subassembly is set the distance X0 between a position of a projection 6a end of a planer mover 6 against which bears a leaf spring 1 and a position of a planer portion 14a of the holder 14 for supporting the peripheral edge of the leaf spring 1 to coincide approximately with a desired one. Thus, the deflection amount of the leaf spring 1 when the valve is closed becomes a set value exceeding the lift of the valve body 2. Thus, while the valve body 2 is lifted, it receives the reaction of the leaf spring 1 so that the movement of the valve body 2 is stabilized to eliminate the fluctuation of flow.

CONSTITUTION:N type InP thin film crystal layers 4, 8, a P type InP thin film crystal layer 6  and InGaAsP thin film crystal layers 5, 7 are made to grow in order on an InP substrate 9 using  the epitaxial growth technique to form a wafer consisted of a quanternary crystal of InGaAsP.  After a part of the wafer is removed by etching up to the InP crystal layer 6, electrodes 1, 2, 3  are formed respectively at both ends of the wafer and on the surface of the InP crystal layer 6. At  this time, band gap energy of the crystal layer 5 is set larger than that of the crystal layer 7.  Radiation from the crystal layer 5 making the P-N junction between the electrodes 1, 3 as the source of light is made to be absorbed in the crystal layer 7, and a photo current is made to flow  between the electrodes 2 3 to perform monitoring of the source of light. Accordingly because the  effective light receiving area of the photodetector is expanded and the distance between the source  of light is reduced, coupling efficiency of both can be improved to enable to enhance monitoring  efficiency of the photodetector.

Filed: 1990-04-27
Abstract: PURPOSE: To bring the forms of sparks to be suitable for a specific analysis to perform by measuring the current passing through the sparks by a resistor and a comparator and making the amplitudes of the various parts of the sparks independently changeable. CONSTITUTION: A spark generator contains a DC supply, crosses a spark gap between an electrode 3 and a sample 4 and is connected via a transistor switch 22, an inductance 23 and an initiator 24.

A comparison between the measured current and the reference current is performed every 10 microseconds, and the transistor switch 22 is opened or closed by a driver 28 depending on whether the measured current is larger or smaller than the reference current. It is thus possible to bring the forms of the sparks to be suitable for a specific analysis.

Abstract: PURPOSE:To decide the idling condition reliably and to perform deceleration cut control accurately by providing means for deciding such condition where the output from a water temperature sensor is below predetermined level while the output from a throttle valve sensor or an injection pulse width is below predetermined level. CONSTITUTION:Under operation of car, the throttle opening TH and the water temperature Tw to be detected through a throttle sensor 20 and a water temperature sensor 46 are taken into a control circuit 54 to decide at first whether the water temperature Tw is below predetermined level T.

If the rotation is higher than predetermined level, it is decided to be deceleration thus to perform fuel cut. While if Tw>=T, the operating condition of an idle switch in the throttle sensor 20 is decided to set an idle flug if it is turned on.

Title: File recovery system for decentralized processing system
Inventor: WATANABE YOSHIO
IPC: G06F12/00
Filed: 1984-06-01
Abstract: PURPOSE:To attain a function-based file copy system suited to a decentralized system by selecting a function module of the copy side equal to a function module among the function modules forming the entire decentralized system. CONSTITUTION:The function modules are classified into three types A, B and C. An A function module of a CPU7 transmits en bloc the copy request annoucement of the A function. This annoucement is received by CPU6, 8 and 10 of other modules of the same function A. Thus the unique CPU numbers allocated to own CPU are transmitted en bloc in reply together with the request reception announcement. In case the CPU8 is selected as the one at the copy side, the start request of the A function module is shunted and preserved until the copy is over. Furthermore, the file contens controlled by a module itself are sent en bloc after conversion into a fixed transmission format. At the side to be copied, the copy file data is received for file recovery. When the copy is over, the A function module executes the start request processing for the shunted A function module and is reset to a steady state.

Title: Solid high molecular electrolyte fuel cell
Inventor: KAMATA HIROYUKI
IPC: H01M8/10
Filed: 1996-04-09
Abstract: PROBLEM TO BE SOLVED: To prevent the deterioration of cell performance. SOLUTION: Fluororesin 8 such as PTFE and the like having water repellent effect is mixed into the electrode layer of an oxygen electrode 2 or a carbon paper board constituting a cell 7. Mixing amounts of the fluororesin 8 are arranged so as to change on a gas inlet side I and on a gas outlet side O. Since the water amount produced by an electrode reaction on the gas inlet side I is small, the amount of the fluororesin 8 is set to be small. Thereby, since the fluororesin not contributing the electrode reaction is little on the inlet side I, the effective area of the electrode are not allowed to be small so that cell performance is not caused to deteriorate. Since the mixing amount of the fluororein 8 is large on the outlet side O where the amount of produced water is large, water repellence is conducted so that the electrode reaction is not hindered.
