Title: Integrated circuit with protecting circuit
Inventor: ADACHI KAZUNOBU
IPC: H01L27/04
Filed: 1980-11-28
Abstract: PURPOSE:To prevent the damage of a logic circuit part of an IC even if erroneously inserted and connected by sealing a unidirectional conductive element in the package of the IC together with a logic circuit IC chip. CONSTITUTION:When the positive and negative of the polarity of a voltage to be applied to an IC is erroneously applied to a terminal 3 with negative voltage and to a terminal 8 with positive voltage, the junction between the emitter and base of the transistor 6 of a protecting circuit 2 is reversely biased, causing the transistor 6 to be cut off, with the result that the current flowing between the emitter and the collector of the transistor becomes zero. Therefore, reverse po- larity is not applied between the lines A and B at both ends of the logic circuit 1, and many transistors of the logic circuit 1 can be avoided from being damaged.

Title: Heat treatment for steel
Inventor: ISOTANI TAKESHI
IPC: C23C8/32
Filed: 1996-06-27
Abstract: PROBLEM TO BE SOLVED: To exceedingly refine the grain size of a steel and to improve its fatigue strength, pitting strength and impact strength by executing a secondary quenching process of increasing the temp. of a steel up an austenitic region after carbo-nitriding and quenching processes. SOLUTION: In treatment T1, carburizing is executed in an atmosphere contg. carbon to diffuse carbon over the surface of a steel. Next, in treatment T2, the temp. of the steel is increased in an atmosphere contg. ammonia, and nitriding is executed. Then, after oil quenching, treatment T3 is executed. The T3 is a secondary quenching stage, and ordinarily, the temp. of the steel is increased in a protective atmosphere of a reducing gas such as a carburizing gas to soak the steel, and quenching is executed. Next, treatment T4 is a tempering stage executed mainly for preventing quenching cracks in the steel. By the carbo-nitriding and quenching stages in the T1 and T2, the steel transforms from austenite to martensite to increase the dislocation density in the surface of the steel and also to increase carbon nitrides.  By the stages of T3 and T4, the dislocation density of the surface increases, and the grain size is refined.

Title: Semiconductor laser diode for standardized light source
Inventor: TORIKAI MASAHIRO
IPC: H01S5/00
Filed: 1996-06-07
Abstract: PROBLEM TO BE SOLVED: To enable a semiconductor laser diode to be improved in accuracy of chip position and signal detection and lessened in measurement error by a method wherein the laser diode is so constituted as to project laser rays from both its sides. SOLUTION: Laser rays emitted from an LD chip through its front side are projected outside passing through a glass window 1 as they are, laser rays emitted through its rear side are divided in half by a beam splitter 2, half of them are made to impinge on a monitoring PD 6 to serve as a feedback for APC. The other half are projected outside passing through a glass window 1' the same as the laser rays emitted from the front side. By this setup, both laser rays emitted from the front and rear of the LD chip can be effectively used. When an LD chip of this constitution is applied to a positioning light source, the positioning light source can be composed of only a single LD chip, and positioning can be accurately carried out. An LD chip lessened in size, weight, and manufacturing cost can be realized.

Title: Recording device
Inventor: IKEDA KOICHI
IPC: B41J2/485
Filed: 1990-06-28
Abstract: PURPOSE:To prevent decline of throughput in operation under high-speed recording mode with processing load for a processor reduced by a method wherein a thinning-out control circuit is provided 46 that the recording head is made effective therewith alternately for dots on odd-number lines and dots on even- number lines whenever pulses that drive driving elements are outputted. CONSTITUTION:In high-speed recording mode, HP1-HP4 are outputted in series with a signal HT outputted. As PH1 is at 'L', MP1 and MP3 are not outputted. On the other hand, as PH2 is at 'H', MP2 and MP4 are outputted. In the high-speed recording mode, thinning-out of data to be recorded with a recording head 3 can be made by making transistors driving the recording head 3 driven alternately for odd-number lines and even-number lines, namely by making outputting of heat pulses effective alternately. Load to a power source 9 is lightened by making the driving of the recording head 3 made with its dots divided up to four parts. When the number of dots of the recording head 3 increases, it may be possible to divide it into more parts. In the case where there is no need for the division because the capacity of the power source 9 is sufficient, a thinning-out control circuit 11 and a head driving circuit 2 may be used.

Title: Electromagnetic spring clutch
Inventor: SUZUKI KAZUYOSHI
IPC: F16D13/08
Filed: 1983-09-12
Abstract: PURPOSE:To greatly reduce the impact torque when the clutches are connected, by winding the coil spring linked to the armature and the output hub, from the winding surface of the output hub. CONSTITUTION:A spring cover 270 is fixed to an output hub by a bolt 110, whereas a coil spring 206 is arranged on the winding surface 1a which is the cylindrical projecting part of an input pulley 1, and also on the winding surface 4a which is the cylindrical peripheral surface of an output hub 4. Since the coil spring starts winding as soon as an armature 250 rotates, the torque is transmitted rotating the output hub 4 and thus the torque transmission of the clutch with an impact is avoided.

Title: Laser beam machine
Inventor: SANO NAOTO
IPC: B23K26/06
Filed: 1985-08-01
Abstract: PURPOSE:To make the machining highly speedy and accurate by irradiating a laser beam with its scanning by giving the function to perform a double curve movement to the condensing lens of the laser beam. CONSTITUTION:A condensing lens 27 is subjected to a circular motion via a timing belt 30, outer gear 20, etc. by driving the motor 28 of the first condensing lens unit 17. The beam having passed through the first condensing lens is then made incident on the second condensing lens rotating by fitting to the inner gear 31 of the second condensing lens unit 18. Consequently the beam trace becomes the shape combining a circle and circle when the obtaining beam is irradiated on the body to be worked. The laser beam can virtually be scanned accordingly. Consequently the machining can be performed at high speed without any defect and the laser beam machine as well can be made simple and inexpensive.

Title: Method and device for automatically changing speed of bulldozer
Inventor: MATSUSHITA SHIGENORI
IPC: F16H59/66
Filed: 1991-06-13
Abstract: PURPOSE:To prevent the generation of overload in a transmission even when starting is conducted at the neutral position of the transmission on a slope and a speed change lever is set at first speed position when car speed is accelerated in the automatic speed change gear of a bulldozer. CONSTITUTION:The longitudinal inclination detector 5 of a car body is installed to an automatic speed change gear with a forward and backing lever 3, a speed- step select lever 4, a car speed detector 6 and a controller 7. When the speed- step select lever 4 is set to first speed position during a time when a bulldozer travels at speed or more determined at the neutral position of a transmission, the direction of rotation of the output shaft of the transmission is estimated from the inclination of the car body. A speed change step is engaged at third speed when the direction of rotation is the same as the direction selected by the speed-step select lever 4, and engaged at first speed when the direction of rotation is reverse, the difference of the number of revolution on the drive side and the driven side is reduced, and a shock at the time of engaging is diminished, thus preventing the generation of overload.
