Title: Electrode for battery and manufacture thereof
Inventor: MATSUMURA JUN
IPC: H01M50/536
Filed: 1995-10-09
Abstract: PROBLEM TO BE SOLVED: To lessen unevenness of filled quantity of an active material of an electrode for a battery by filling a porous metal body having three-dimensional communicated spaces with the active material from one side so as not to fill from the other side. SOLUTION: While a strip-like porous metal body 1 having three-dimensional communicated spaces is moved, an active material is ejected through a nozzle 3 to fill the porous body 1 with the active material to form an electrode 4 for a battery. At that time, the porous body 1 is not filled with the active material from one side but the other side by adjusting the moving speed of the porous body 1 and an electrode 4 with scarce uneveness of the filled quantity of the active material is obtained. As a result, batteries with uniform capacity can be manufactured using the electrode 4.

IPC: H04L69/40
Filed: 1999-09-16
Abstract: PROBLEM TO BE SOLVED: To prevent peripheral equipment from becoming a hung state by checking data flow between a client and the peripheral equipment and transmitting an unlock sequence to the peripheral equipment. SOLUTION: A system buffer is judged whether it is usable or not when the number of idle-count becomes equal to six, i.e., 2.5 seconds elapse without by the server 10 itself while a server 10 does not receive the data from the scanner. When the buffer is not usable, usability of the buffer is periodically checked and the system buffer is judged whether it is usable or not by the server 10. When the system buffer becomes usable, the 'unlock sequence' of a scanner is transmitted to the peripheral equipment 14 by using a scanner control language(SCL) by the server 10. And after two seconds elapse, a close channel request buffer is transmitted to the peripheral equipment 14 so as to close a channel between the server 10 and the peripheral equipment 14 by the server 10.

The cylindrical stator core 1 is secured by means of through bolts 14 through washers with the outer circumferential face thereof contacting with the inside face of a core supporting rib 12 projecting from the central section. When the stator core 1 is excited in the circumferential direction, the intermediate supporting board 10, the auxiliary rib 11, and the core supporting rib 12 are deformed thus absorbing vibration of the stator core 1. By such arrangement, transmission of vibration from the stator core 1 to the stator frame 2 can be restricted.

Title: Pwm modulator
Inventor: SAWADA YASUYOSHI
IPC: H03K7/08
Filed: 1990-10-02
Abstract: PURPOSE:To control an output duty ratio accurately without applying feedback by changing the amplitude without changing the frequency of a triangular wave used for modulation to make the amplitude of the triangular wave equal to a difference between the peak level and the lowest level of an input signal. CONSTITUTION:A peak level VH of an input signal is fed to a series circuit comprising a diode D1, a resistor R1 and a diode D2. A connecting point between the diode D1 and the resistor R1 is connected to a noninverting input of an operational amplifier OP and an inverting input is connected to a connecting point between a constant current source I1 and a resistor RT. Then the level of the connecting point between the constant current source I1 and the resistor RT is set to a voltage V. A constant current flowing to constant current sources I2, I3 is controlled by the operational amplifier OP and changes with a change in the peak level VH of the input signal. A triangle wave is generated by changing/discharging a capacitor CT by the constant current I. The oscillation amplitude Va of the triangular wave oscillation circuit is expressed as VH-VBE, where VH is the peak level of the input signal VF and VBE is the lowest level of the input signal VF, then the oscillation amplitude Va of the triangular wave is made equal to a difference between the peak level and the lowest level of the signal VF.

Title: Receiver provided with clock oscillation circuit
Inventor: AMANO KAZUYUKI
IPC: H04B1/10
Filed: 1994-10-03
Abstract: PURPOSE: To evade a trouble that an output from a clock oscillation circuit becomes an interfering wave to a receiver by changing the frequency of an output from the clock oscillation circuit when integer times the frequency of the output from the clock oscillation circuit coincide with the received frequency. CONSTITUTION: A frequency measuring circuit 4 measures the frequency of a system clock signal from a system clock oscillation circuit 1 by the use of an accurately adjusted data reference clock held by the receiver 5 as a data clock and judges whether integer times the measured system clock signal frequency coincide with the received channel frequency or not. When both the frequency bands coincide with each other, the interference of an output from the circuit 1 to the receiver 5 is judged, an output is generated from the circuit 4 and supplied to a control voltage generating part 3. The generating part 3 changes the oscillation frequency of the oscillation circuit 1 by slightly changing voltage to be applied to a variable capacity diode D1 in the circuit 1.

Title: Control device for automatic welding machine
Inventor: NAKANO TOMIJIROU
IPC: B23K9/127
Filed: 1995-10-11
Abstract: PROBLEM TO BE SOLVED: To perform welding, with leg surely secured, even for a joint with a gap by repeating computation and compensation for welding conditions until the quantity of a gap filling weld metal is constricted. SOLUTION: A means 41 for setting initial conditions sets welding conditions consisting of electric current and voltage from a welding power source 3 and of a welding speed WS, on the basis of the input information of basic specifications. If a joint has a gap, the initially set welding conditions are initially compensated in the weld metal quantity for an increment proportionate to the gap by a means 44 for computing and compensating conditions; the further added and increased quantity of a gap filling weld metal is supplemented by this initial compensation, with the recompensation repeated for the welding conditions so that the added part may be constricted into nearly zero. As a result, welding is made possible for filling a weld metal in the gap until a leg is secured, assuring the strength of a joint having a gap.

Title: Light source device for exposure
Inventor: MASUDA MIYOJI
IPC: H01J9/227
Filed: 1993-10-21
Abstract: PURPOSE:To prevent an irregularly reflected light as much as possible and improve the precision of exposure by constituting an irregular reflection preventing body arranged on the lower side of an inner casing from a triangle pole having a surface for reflecting light sideways. CONSTITUTION:An inner casing 36 is installed to the inner part of an outer casing 34, and an extra-high pressure mercury lamp 35 as a linear light source is built in its inner part. An irregular reflection preventing body 41 is arranged on the lower surface of the casing 36, and the body 41 is formed from a triangle pole-shaped carbon. Since the body 41 is constituted from the carbon triangle pole having a surface for reflecting the light leaked to the lower part sideways, the light leaked to the lower side from the light source is almost absorbed by the body 41. A part of the light not absorbed is reflected sideways. Thus, since the irregularly reflected light of the light leaked to the lower side is never included in the exposing light and has no bad effect on ultraviolet ray distribution of exposure, exposure precision is improved. Particularly, the body 41 is formed from carbon, whereby absorbing characteristic of light is improved, and the preventing effect of irregular reflection can be improved.
