Title: Compound semiconductor element and manufacture thereof
Inventor: WATANABE KOJI
IPC: H01L31/107
Filed: 1986-06-27
Abstract: PURPOSE:To boost the avalanche breakdown voltage up to high level by a method wherein the carrier concentration difference between a first layer comprising the first conductivity type InP and a second conductivity type impurity diffused layer in the first layer is relieved while the depth of diffused layer is made shallower. CONSTITUTION:The first layer 12 comprising the first conductivity type InP, the second layer 13 comprising the first conductivity type InxGa1-xAs1-y and the third layer 14 comprising the first conductivity type InGaAs taking mesa shape together with the second layer 13 are successively laminated on a semiinsulating InP substrate 11. The second conductivity type impurity diffused layer 15 is formed on the overall surface including the sides of mesa shape taken by the second 13 and the third layer 14 as well as on the surface of the first layer 12 around the mesa shape. At this time, the impurity concentration of a P<+>type InP layer of diffused layer 17 in the highest electron concentration is lowered since the P<+>type InP layer with a curvature part is nearest to the N<->type InP of the first layer 12, layers and the junction of the two is shallow, so that avalanche break down hardly takes place in case of inverse bias.

Title: Current limit control system for dc motor
Inventor: NOJIRI YUKO
IPC: H02P7/288
Filed: 1990-06-11
Abstract: PURPOSE:To protect transistors or the like against breakdown by performing current limitation based on a third reference voltage and elongating duration of output from a monostable oscillator when abnormal interruption and reset of power supply are repeated and sustained for a predetermined time or longer. CONSTITUTION:Resistance of a resistor 20 is selected such that a reference voltage, to be set by resistors 8, 9, 17, 20, will be sufficiently lower than a second reference voltage. Even if the resistance of the resistor 20 is set at 0OMEGA, a current corresponding to collector and emitter voltage flows repeatedly to increase heat generated in a transistor 5 which thereby may be broken down. Consequently, output from a detector 23 is fed through a resistor 26 to a transistor 24 which thereby is turned ON to connect a capacitor 25 in parallel with a capacitor 12 determining the duration of output from a monostable oscillator 11 thus elongating the duration of output from the monostable oscillator 11. According to the arrangement, switching loss per unit time of the transistor 5 is reduced, generation of heat is suppressed and the transistor 5 is protected against breakdown.

Abstract: PURPOSE:To obtain an electromagnetic flow meter excellent in linearity and having high sensitivity, constituted so that the structure of a flow passage is set to a U-shape wherein a fluid reciprocates in the same magnetic field and the strains of magneic fields in forward and rearward passages are set off to preserve a uniform magnetic field not dependent on a flow speed. CONSTITUTION:An electromagnetic flow meter is constituted of a U-shape flow passage 11 comprising a round pipe, a magnet 12 comprising a permanent magnet or an electromagnet and electrodes 13a-13c provided at right angles to the U-shape flow passage 11. A liquid metal 14a is flowed in the U-shape flow passage 11 from one end thereof as a stream F1 and the liquid metal 14b is flowed out as a stream F2 after turned back, and the inflow and outflow amounts are set so as to be made equal. The phenomenon of magnetic field strain is pushed away to the downstream side with respect to the stream F1 to be brought to magnetic flux distribution B1 and pushed away to the upstream side with respect to the stream F2 to act so as to be brought to magnetic flux distribution B2 but, because the flow passage dimension of forward and rearward passages of the U-shape flow passage 11 are equal, both magnetic field strains are set off to hold magnetic flux distribution having the same shape as stationary magnetic flux distribution B0.

Patent JP-H0443377-A (JP)
Title: Developing device
Inventor: IWATA NAOTAKA
IPC: G03G15/08
Filed: 1990-06-09
Abstract: PURPOSE:To prevent the quality of a visible image from being deteriorated by using a toner carrier which carries toner by attracting electrostatically charged toner by a closed electric field and providing a vibration generating means for giving vibration to a toner layer thickness regulating member. CONSTITUTION:The toner is strongly triboelectrified by the friction of a toner supply roller 6 and a developing roller 5 and held on the surface of the roller 5 by the strong action of the fine closed electric field. Therefore, a large quantity of toner having high charge is carried on the roller 5. When the layer thickness of toner carried by the roller 5 is regulated by a doctor blade 8, the toner which is fully electrostatically charged is strongly held on the surface of the roller 5 by the fine closed electric field and only the toner which has a large quantity of electrostatic charging is carried to a developing area 9 more than in a conventional manner to visualize an electrostatic latent image. By impressing alternating voltage, namely, bias voltage periodically changed on the doctor blade 8 by a power source 50, the blade 8 vibrates with fine amplitude. Thus, the visible image of desired density is obtained, and unevenness is prevented from being formed in the image.
