Title: Pinion clutch mechanism for starter
Inventor: KAWASE OSAMU
IPC: F02N15/06
Filed: 1981-07-28
Abstract: PURPOSE:To enable to bring a pinion into and out of gear engagement smoothly, by selecting the axial thickness of a damper member for a starter clutch to be smaller than the value of the interstice between inner surface of an outer clutch member and a stopper minus the thickness value of a splined tube at its flange portion. CONSTITUTION:In the state that a damper member 9 is not compressed between a splined tube 7 and an outer clutch member 6, a gap g of about 1.5mm. exists between the splined tube 7 and the damper member 9. With starting of an engine or the like, a pinion clutch mechanism applies a thrust to a pinion 5 by the function of its inertia and helical spline 4 and compresses a return spring 12, so that the pinion 5 is brought into mesh with a ring gear 14 and the engine is cranked. However, when the engine speed is raised subsequently, the pinion 5 comes out of engagement with the ring gear 14 and is brought back to its original position. Here, since the gap g is formed to locate on the right or the left side of the flange portion of the splined tube 7, it is enabled to absorb engine pulsation, so that the pinion 5 can be brought into or out of engagement with the ring gear 14 in a reliable manner.

Title: Blow mold and molding method thereof
Inventor: TAKATORI HIROYUKI
IPC: B29C49/48
Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To effectively reuse a burr portion without pre-forming by a method wherein projected outside mating surfaces are provided and, at the same time, space parts are provided. SOLUTION: A pre-blowing is performed in a parison and then molds are clamped together and, at the same time, a blowing pressure is applied both in space parts P and in the parison. In this case, the blow air pressure in the space part P may well be lower than the blowing pressure. On the other hand, the air interposing between the parison and a skin material T and a mold cavity surface is naturally exhausted or forcibly sucked with a suction fan or a vacuum pump through vent holes provided on the mold. Thus, the surface properties are improved. After the completion of cooling is confirmed, a molding is taken out.  By taking out of the molding obtained by performing a near conventional laminating blow molding, the resin at burr portion is pressed against a mold surface by means of air or/and needle-like projections S, resulting in cooling and solidifying under the condition being held at the state separated from the skin material T, no bonding with the skin material is present.

Abstract: PURPOSE:To make a threshold voltage Vth be 0.1 [V], while suppressing the increase of the thickness of an InAlAs layer to a slight extent, by laying the p-type InAlAs layer between a channel layer and a layer for feeding electrons. CONSTITUTION:A buffer layer 22, a channel layer 23, a p-type In0.52Al0.48As layer 24, a layer 25 for feeding electrons are formed on a substrate 21 in the order described. Devices are isolated from each other, and Si ions are implanted in between a source and gate and in between the gate and a drain, and further, n<+>-type impurity diffusion regions 26 are formed. A source electrode 27, a drain electrode 28 and a gate electrode 29 are formed. The p-type In0.52Al0.48As layer 24 is 55 [Angstrom ] in thickness and is 2X10<18> [cm<-3>] in impurity concentration. As shown in a diagram, in order to obtain Vth=0.1 [V], the thickness of the p-type InAlAs layer needs dp=55 [Angstrom ] in the case of the impurity concentration NA=2X10<18> [cm<-3>]. Thereby, the increase of the film thickness can be suppressed to a slight extent in comparison with 290 [Angstrom ] obtained in prior arts.

Title: Head feeder
Inventor: HORI KOJI
IPC: G11B21/02
Filed: 1990-05-10
Abstract: PURPOSE:To improve the response at high speed head feeding by detecting a motor speed by means of the detection of a counter electromotive force of a drive motor and forming a feedback loop for the speed servo automatic control. CONSTITUTION:A drive motor 4 drives a head feed mechanism 3 with at least two stages of feeding speed selection such as the normal speed feeding and the high speed feeding. Then an access pulse is selected by a changeover switch 8, amplified by a drive amplifier 7 and fed to the drive motor 4, and a counter electromotive force produced in a coil of the motor 4 in this case is detected by using a bridge circuit 5 and a differential amplifier 6 as a rotating speed of the drive motor 4. The counter electromotive force in response to the motor drive speed is fed to an inverting input terminal of the motor drive amplifier 7, resulting in being fed back to the motor 4, then a closed loop circuit as to the speed servo is formed thereby enabling steep rising (acceleration) and falling (deceleration) to be realized. Thus, the response at the high speed head feeding is enhanced.
