Title: Power transmission device for automobile
Inventor: SUGINO MASARU
IPC: B60K17/30
Filed: 1986-09-25
Abstract: PURPOSE:To prevent pull-in of torque generated during gear shift of an automatic transmission and to reduce the generation of gear shift shock, by a method wherein the spring constant of the shaft of a gear following and after a gear, being increased an inverse number-fold as large as a square of an apparent final gear ratio, is decreased. CONSTITUTION:When a fluctuation in torque during gear shift of an automatic transmission is produced, the fluctuation in torque is transmitted to a support member 3 and a flange part 5 through a drive shaft 1. Meanwhile, rotation torque from a drive wheel is applied on a second flange cover 8, and relative twist angle displacement responding to a difference between the two torques occurs between a flange part 5 and a second flange cover 8. Since twist angle displacement is changed according to the magnitude of the resilient force of a coil spring 6 and a fluctuation in torque, a fluctuation in torque is absorbed by the coil spring 6.

Title: Backup roll material having crack resistance
Inventor: GOTOU HIROSHI
IPC: C22C38/00
Filed: 1982-12-27
Abstract: PURPOSE:To provide a titled roll material having excellent resistance to crack propagation by specifying the compsn. of a Cr-Mo-V steel contg. C, Si, Mn, etc. CONSTITUTION:A backup roll having crack resistance consists essentially of 0.50-0.60wt% C, <=1.00% Si, <=1.00% Mn, 4.60-5.50% Cr, 0.40-0.50% Mo, 0.10-0.30% V, and the balance incidental impurity elements and Fe. C among the above-mentioned component elements decreases an abrasion loss but the content at the upper limit or above is undesirable as a fracture toughness value decreases sharply. Si is added as a deoxidizing agent and increases the depth of hardness but is not required to be added at the upper limit or above. Mn improves the depth of hardening but if it is added too much, the sensitivity to hardening crack is increased. Cr improves the desired characteristic and fracture toughness. Mo improves wear resistance and tempering characteristic. V improves the fracture toughness value, and improves crack resisting characteristic, thereby improving the characteristic of avoiding fracture even if a crack is generated.

Title: Detecting device for meandering of running medium
Inventor: KIKUCHI TORU
IPC: B65H23/032
Filed: 1984-10-29
Abstract: PURPOSE:To detect whether a form meanders or not by providing a form presence/absence sensor which detects whether there is a form between the light emission part and photodetection part of a sensor. CONSTITUTION:A microswitch 6 operates by contacting the form 10 directly to detect whether or not there is the form between the light emitting part 3 and photodetection part 4 of the meandering sensor. When the switch 6 detects no form between the light emitting part 3 and photodetection part 4, a signal indicating the absence of a form is obtained from the meandering sensor as long as the sensor is normal and if a signal indicating the presence of a form is obtained from the meandering sensor, it is judged that the sensor is abnormal. Thus, the output is checked when there is no form between the light emitting part 3 and photodetection part 4 to confirm whether the meandering sensor is normal or not, thereby preventing an error in the detection of form meandering.

SOLUTION: After etching, displacement from diluted hydrofluoric acid liquid 110 to pure water 109 is performed. A wafer 101 is washed for a specified time. At this time, isopropyl alcohol(IPA) vapor 111 is supplied from the upper part of a processing tank 107. The IPA vapor 111 is cooled on the surface of the pure water 109 and liquified. A thin film is formed on the water surface. The surface tension of the pure water 109 is weakened, and the pure water is made easy to flow. The particles removed from the surface of the wafer 101 are discharged together with the pure water 109. After the end of washing, the supply of pure water 109 is stopped. After the elapse of the specified time, the wafer 101 is lifted up. Thus, even very minute particles remaining on the surface of the pure water can thereby be removed.

IPC: F16B3/00
Filed: 1982-12-28
Abstract: PURPOSE:To contrive an improvement in durability by so constituting that the effect of concentration of stress becomes minimum, by a method wherein a fitting part provided within a specific angle range centering around a line connecting the center of rotation of a movable component with an impressing point of stress and a fitting part on a rotary shaft are connected by a stationary component with each other. CONSTITUTION:A pin hole is provided on a movable arm 4 so that the center of the pin hole 14 is positioned within an angle range of 1/+ or -sin(1/alpha) to a neutral shaft in case a coefficient of concentration of stress in the pin hole 14' is given as alpha and the movable arm 4 and its rotary shaft 4' are secured by driving a pin into the pin hole 14'. When the above-mentioned device is compared with a conventional case wherein the movable arm 4 and its rotary shaft 4' are secured so that the pin hole 14' meets at right angles with the neutral shaft, distribution of impact bending stress to be generated at the time of interrupting action is different from that of the foregoing device, through which influence of concentration f stress due to the pin hole 14' is small. Even the maximum stress due to the concentration of the stress at a part of the pin hole 14' does not exceed the maximum bending stress of the external circumferential part of the shaft. Then it does not happen that the pin hole 14' becomes a generating point of fatigue crack of the rotary shaft 4'.

IPC: H01L21/20
Filed: 1982-12-27
Abstract: PURPOSE:To enhance the grade of a single crystal silicon formed on a single crystal insulator by once dissolving a single crystal silicon layer formed on a single crystal insulator, and then solidifying and single-crystallizing it again. CONSTITUTION:After a single crystal layer 2, for example, consisting of magnesia spinnel is formed on a silicon single crystal substrate 1, a silicon (Si) single crystal layer 3 is formed thereon by the chemical vapor epitaxial growth method. The surface of silicon single crystal layer 3 is scanned by the laser beam spot and thereby the crystal is sequentially melted. Namely, only the region 4 indicated by the hatched portion dissolves by the irradiation of laser beam. Thereafter the substrate 1 is cooled naturally and the dissolved region 4 is solidified. Thereby, recrytallization of region 4 progresses with the region in contact with the region 4 of silicon layer working as the nucleus of growth. As a result, a high grade silicon single crystal can be obtained.
