Title: Production of fiber-reinforced aluminum alloy
Inventor: TSUKAMOTO KENJI
IPC: C22C47/20
Filed: 1982-05-21
Abstract: PURPOSE:To form a composite product having high strength and elasticity, by laminating reinforcing fibers having good wettability with Al and foil of a low m.p. Al alloy corresponding to an Al brazing alloy alternately, and heating the same under pressure in a nonoxidative atmosphere thereby combining both materials.

Title: Envelope feeder
Inventor: SHIMOKAWARA JUN
IPC: B65H3/04
Filed: 1988-04-08
Abstract: PURPOSE:To enable alternating use of envelopes stacked in an envelope feeder and paper other than envelope without concern about a head gap by providing a movable section which moves in accordance with whether a printing medium to be supplied is an envelope, then allowing the movable section to be engaged with a guide shaft and adjusting the head gap. CONSTITUTION:When an envelope feeder is used, the movable section of the feeder is moved forward by operation of a keeping solenoid, and a gap lever 37 is caused to swing by a lever catch 22 at the tip of a link supported by the movable section. This swing action results in the rotation of a guide shaft 34 and the subsequent separation of a platen 32 from a printing head 31. Thus the gap between the printing head 31 and a platen 32 is widened and envelopes 10 stacked in the envelope feeder are fed. After this, when the use of the envelope feeder is finished, the movable section of the keeping solenoid is retracted to narrow the gap between the printing head 31 and the platen 32 and the envelope feeder is set ready for feeding paper other than the envelope.

Title: Thermal head
Inventor: MIKAMI IZUMI
IPC: B41J2/335
Filed: 1984-04-27
Abstract: PURPOSE:To make the execution of the accurate positional control of a recording paper to be set up possible, by a method wherein the sensor detecting a fixed portion of recording paper is established on the insulating substrate on which a heating resistor row is formed. CONSTITUTION:When the initial color is printed, the mark provided at the tip of recording paper 5 is, at first, detected with the optical sensor provided on the insulating substrate 2 of a thermal head 1 and while the recording paper 5 has been established at a fixed position is recognized with its output, then, a required portion of the heating resistor row 3 is made to generate heat and the printing is carried out. When the next color is printed, the recording paper 5 is returned reversely and the mark is detected again with the sensor 7. Then, the subsequent printing is carried out. Color printing is carried out by repeating this operation. In that case, because the sensor 7 is arranged in the same row as that of heating resistor row 3, the positional precision can be more raised being not subjected to the effect by the tension, slackening, etc. generated when the recording paper 5 returns, and the positional precision can be more raised.

IPC: G06F11/30
Filed: 1989-04-07
Abstract: PURPOSE:To reduce overhead by setting up limit time generated first of all as check time, and only when the current time the check time, executing the time-over processing of a process whose limit time is less than the current time. CONSTITUTION:Without controlling time up to time-over in each process, the limit time determining time-over is controlled in each process, the first limit time out of respective limit times is set up as the check time 5213 and the current time 5212 is compared with the check time 5213 at a fixed period. When the current time 5212 exceeds the check time 5213, the time-over processing for an unended process whose limit time is smaller than the current time 5212 is executed. Since the time-over processing is executed in accordance with the limit time of the process proposed to be ended at first without executing time-over processing in each fixed period, useless time-over processing is not generated.

Title: Mechanism of clamping distributor to engine
Inventor: KUNIMITSU TOSHIYUKI
IPC: F02P7/02
Filed: 1981-06-05
Abstract: PURPOSE:To provide a mechanism of clamping a distributor to an engine which is capable of setting the distributor only at a correct position, by at first drilling an unthreaded hole in a plate-like support section by use of a drill bolt having a drill at its top, at the same time cutting thread in said hole, and then fixing a distributor to the support section. CONSTITUTION:In clamping a distributor 1 to an engine 2, a cylindrical part 1c of the distributor 1 is at first inserted into a hole 2b formed in a clamping boss 2a until its clamping flange 11a comes into contact with a plate-like support section 12, and then the distributor 1 is turned to a position where a standard ignition timing can be obtained. Thereafter, a drill bolt 13 is inserted into a through-hole 11b formed in the flange 11a and an unthreaded hole is formed in  the support section 12 by a drill part 13a of the bolt 13, utilizing the through- hole as a guide. At the same time, thread is cut in the hole and formed in the  section 12, and then the bolt 13 is tightened with a sufficient torque. Here, since  arrangement is such that the length l1 of the drill part 13a is greater than the thickness l2 of the section 12, thread cutting is not disabled by cuttings. By thus clamping a distributor to an engine by use of a drill bolt, the distributor is not set at a wrong position, so that correct ignition timing can be obtained.

Title: Variable balanced circuit network
Inventor: SHIMIZU HIROSHI
IPC: H03H19/00
Filed: 1978-07-18
Abstract: PURPOSE:To eliminate the limitation for the number of switches by giving control to the switches connected in series to the resistance and capacitor of the variable balanced circuit used for the hybrid via the frequency higher than the signal frequency and with every switch. CONSTITUTION:The circuit network comprises switches 19-22, resistances 23 and 24 plus capacitors 26-30 each. Switches 19-22 are controlled by switch control circuit 31. In this case, switches 19-22 are opened and closed with the frequency higher enough than the signal frequency applied between terminals 7 and 8. And this switch rate is varied by changing continuously or dispersively the impedance to the signal component between terminals 7 and 8. Thus the degree of freedom more than the square of the number of switches is secured by controlling the switch rate of the switches, thus increasing the variable flexibility.

IPC: F02P3/08
Filed: 1994-03-31
Abstract: PURPOSE:To shorten the converter stopping time to prolong the charging time, and thereby improve the ignition performance by keeping impedance between the gate and the cathode or the earth of a thyristor lower for the period of time from the trigger signal terminated time of the thyristor up to the converter stopping signal terminated time, and thereby increasing the holding current of the thyristor. CONSTITUTION:When a switch 1 is closed, a transistor 5 is turned ON/OFF, and a capacitor 8 is charged. At this time, when the output of a pulser coil 10 is inputted to a trigger circuit 11, a thyristor 12 is triggered to a set ignition timing to ignite a fuel-air mixture. In this case, a transistor 22 is turned ON only for the period of time from the trigger signal terminated time up to the converter stopping signal terminated time, namely only when the output of the trigger circuit 11 is L by a gate circuit 21, and the output of a converter stopping circuit 17 is H. Thus, a resistance 23 is inserted between the gate and the cathode of the thyristor 12 to decrease impedance between the gate and the cathode.
