Title: Vibration control device for rotor
Inventor: OKUNO HITOKI
IPC: G03G15/00
Filed: 1998-09-11
Abstract: PROBLEM TO BE SOLVED: To provide a vibration control device for rotor, which will not generate a drive loss in the constant speed rotating condition and can certainly suppress eventual variation in the rotating speed.

Title: Controller for dc motor
Inventor: YAGUCHI OSAMU
IPC: H02P7/288
Filed: 1987-10-13
Abstract: PURPOSE:To eliminate a restriction current at the restriction stopping position of a motor by connecting a driving transistor of a rotation detecting transistor which is turned ON by the induced electromotive force of a DC motor. CONSTITUTION:When a motor M is rotated in a normal direction by an external force, a positive voltage is generated at the terminal T1 of the motor M, and a negative voltage is generated at the terminal T2. A rotation detecting MOSFET transistor Q1 is turned ON by the induced electromotive force, and a driving MOSFET Q2 is also turned ON, so that the motor M continues its normal rotation. A negative pulse is periodically generated in the induced electromotive force during the rotation of the motor M, and the transistor Q1 is periodically turned OFF. In this case, when the motor M is restricted, the transistor Q1 is no longer turned ON. Thus, the power supply current interruption at the time of the restriction can be effectively performed.

Inventor: TAKEMASA KEIZO
IPC: H01S5/00
Filed: 1998-09-11
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device suited to high-temperature operation in which the efficiency of carrier injection is improved and its manufacturing method. SOLUTION: A semiconductor laser 100 is provided with an optical waveguide 120. The optical waveguide 120 is formed by piling up in order a lower clad layer 130 made of n-InP, a core layer 140 and an upper clad layer 150 made of p-InP. The core layer 140 is formed by piling up in order a lower SCH layer 141 made of InGaAsP, a Hall stop layer, an active layer 145 made of AlInGaAs, an electron stop layer 147, and an upper SCH layer 149 made of InGaAs from the side of the lower clad layer 130. In this semiconductor laser 100, the optical loss in the core layer 140 can be reduced by forming the SHC layer (optical confinement layer) of InGaAsP which absorbs less light than AlInGaAs. Further, the efficiency of carrier injection to the active layer 145 can be improved by providing both Hall stop layer 143 and electron stop layer 147.

Title: Magneto-optical disk device
Inventor: SUZUKI HARUYUKI
IPC: G11B11/10
Filed: 1988-10-13
Abstract: PURPOSE:To eliminate the influence of the in-phase noises and to obtain a reproduction information signal by securing the difference between the output signals of two variable gain amplifiers which receive the output signals from two photoelectric transducers and are controlled by the 1st and 2nd feedback loops. CONSTITUTION:The reflected light of a medium which records the information in the form of the change of the magnetizing direction is divided into two beams by a polarized beam splitter and supplied to the photoelectric transducers 1 and 2. The photoelectric transducer outputs are amplified by the variable gain amplifiers 3a and 4 and reproduced after the differential amplification undergone via a differential amplifier 5. In this case, the output signal of the amplifier 5 is integrated by an integrator 6 via a 1st feedback loop, and the amplifier 4 is controlled via an adder 7. While the output signals of both amplifiers 3a and 4 are compared with the reference voltage by a subtractor 9 via an adder 8 and a 2nd feedback loop. At the same time, the amplifiers 3a and 4 are controlled via an integrator 10 and the adder 7 respectively. Thus it is possible to eliminate the offset and the in-phase noises to the amplitude.

Title: Transmitting part structure for walking type agricultural work machine
Inventor: SAGATA MAKOTO
IPC: F16H15/52
Filed: 1987-10-14
Abstract: PURPOSE:To obtain space, rotatably supporting a wheel, in the bottom end while facilitating assembly and disassembly of a transmitting part by connecting an engine output shaft to an input shaft being associated between an engine and a friction type continuously variable transmission and a transmitting shaft, transmitted by reduction from the input shaft, to a transmitting shaft of a chain transmission mechanism being associated through a bevel gear. CONSTITUTION:An engine output shaft 22 is connected to an input shaft 1 being associated between an engine E and a friction type continuously variable transmission A, and a transmitting shaft 9, transmitted in a reduction condition from the input shaft 1, is connected to a transmitting shaft 10 of a chain transmission mechanism B being associated through a bevel gear mechanism 11. As the result, enabling a cover to be omitted or simplified, assembly and disassembly of a transmitting part can be easier performed than in the past. While parallelly arranging the transmitting shaft 9 in the bottom lateral side part of the input shaft 1, a height difference is decreased while a distance, enough for transmitting power to the transmitting shaft 9, is ensured. That is, a vertical length of the chain transmission mechanism B of narrow lateral width is increased by the amount of suppressing a vertical length of the friction type continuously variable transmission A of wide lateral width. Accordingly, sufficient space for rotatably supporting a wheel can be obtained in the bottom end.

Title: Steel member excellent in piping resistance and fatigue strength and its production
Inventor: HANAKAWA KATSUNORI
IPC: C22C38/18
Filed: 1992-09-29
Abstract: PURPOSE:To obtain a steel member excellent in pitting resistance and fatigue strength in which sufficient pitting resistance and spalling resistance can be secured even in a steel member applied with a high bearing pressure. CONSTITUTION:Steel stock contg., as essential components, 0.7 to 1.0% C, 0.9 to 1.5% Si and 1.0 to 3.5% Cr is subjected to a high carbon carburizing treatment to dispersedly form carbides on the surface part of the steel stock, and after that, the steel stock is subjected to austempering treatment. By the high carbon carburizing treatment, the hardening of the surface part is attained to improve its pitting resistance. Moreover, by the austempering treatment, its toughness and fatigue strength are improved over the surface part and the inner part to improve its spalling resistance. Since this steel stock contains C, Si and Cr by the same prescribed amounts, by the hardness of carbides, bainite and martensite and compressive residual stress generated by the martensitization owing to the strain induced transformation of retained austenite, its fatigue strength can be improved.
