Title: Supersonic motor
Inventor: KUWABARA SHIGEO
IPC: H02N2/00
Filed: 1990-03-22
Abstract: PURPOSE:To obtain left and right rotation which can be operated easily and is stable by supplying power to one of two piezoelectric elements and interrupting power supply to the other. CONSTITUTION:In a drive unit 1, two piezoelectric elements 1-a which expand and contract are paired such that one for forward rotation is placed at side A while the other for backward rotation is placed at side B, each independent drive body 1-b is placed at its one edge, and one U-shaped inertia body 1-c is attached to the other edge so that two piezoelectric elements 1-a are connected. When a pulse-shaped high-frequency voltage is applied only to the side A, the piezoelectric element 1-a at the side A expands in upper and lower directions and is displaced. This displacement is propagated to the drive body 1-b as a wave and advances in lower direction as Y, Y' longitudinal waves. The longitudinal wave Y' which advances toward a tip surface 1-b'' of the drive body 1-b crosses vibration at right angle and are synthesized, thus enabling the vibration to be in circular motion with vector velocity (X). Since a rotary circular plate 2 is pressed against a tip surface 1-b''', the rotary circular plate 2 moves from right to left due to the friction force, namely rotates to the left.

IPC: H01S5/00
Filed: 1994-03-15
Abstract: PURPOSE:To prevent deterioration of laser characteristics and temperature characteristics, by hanging the carrier concentration of a P-type buried layer in a current blocking layer which comes directly into contact with the side surface of an active layer, in the inside region and the outside region. CONSTITUTION:Clad layers 21 and 25 are formed below and above an active layer 23, respectively. Current blocking layers 26, 27 are formed on both sides of the active layer 23.

IPC: B21D37/20
Filed: 1981-05-12
Abstract: PURPOSE:To obtain a pressure die inexpensively without expansion of a melt- sprayed layer, by using a slurry hardened material, where water glass is applied on the surface, as a melt-sprayed model in the production method for the pressure die where the melt-sprayed model molded from a basic model is used. CONSTITUTION:A basic model 2 consisting of plaster is stored in a frame 3, and a core 4 is provided, and a slurry 5 is flowed between the core 4 and the model 2 and is solidified. The slurry 5 consists of the mixture between A2O3.ZrO2.SiO2 powder and ethyl silicate as a tackifier or the like. The solidified slurry 5 is sintered in a furnace, and a water glass 8 is applied on the surface and is allowed to permeate, and the slurry is hardened in CO2, thus obtaining a melt- sprayed model 6 consisting of a ceramic part 7. By this glass 8, the difficulty of formation of a thick melt-sprayed layer due to the roughness of the part 7 is eliminated, and the fragility of the part 9 is covered. A hard metal is melt- sprayed to a surface 9 of the glass 8 to form a layer 10; and in this case, water of crystallization and matters of thermal decomposition are not scattered from the model at a high temperature. After the layer 10 is backed with a backing material 12, and the model 6 is removed by destruction, thus obtaining a pressure die having the layer 10.

Title: Speed reduction control device of internal-combustion engine for vehicle
Inventor: NOYORI TAKAHIRO
IPC: F02M3/045
Filed: 1982-04-28
Abstract: PURPOSE:To prevent an excessively lean air-fuel ratio and to improve an operating characteristic, by providing a speed reduction control device adapted to cut supplies not only of a fuel but also of an air-fuel ratio feedback controlling air in a predetermined speed reduction operating range. CONSTITUTION:When a speed reduction is effected, a control unit 32 is judged to fall within a fuel cut range upon finding that an engine speed N is great as detected by a rotation sensor 30 and a throttle angle theta is lower than a preset level as detected by an idling switch 32. In this manner, an electromagnetic valve (not shown) is caused to close and a throw fuel passage is interrupted, thereby cutting a supply of a throw fuel. At the same time, a step motor actuator 36 provided in bleed air passages 40 and 42 is caused to fully close and a supply of bleed air to a carburetor 4 is cut off. Thus it is possible to prevent an air-fuel ratio from becoming excessively lean at the time of speed reduction and an engine stall which would otherwise take place in releasing a fuel supply cut.

Title: Charge transfer device
Inventor: SHIRAKI HIROMITSU
IPC: H01L29/772
Filed: 1984-04-09
Abstract: PURPOSE:To enable charge transfer at high speed by small power consumption by forming a thin layer having a conduction type reverse to a semiconductor substrate having one conduction type on the upper surface of the substrate and providing a means completely depleting the thin layer and shaping a charge transfer elctrode on an insulating film formed on the thin layer. CONSTITUTION:When voltages are applied in three-phase pulses of phi1=phi3=0 and phi2= positive and there are signal charges under a phi2 electrode, reverse bias voltage 303 is increased sufficiently, and P type semiconductor thin layer 302 is depleted completely. A series capacitance of the capacitance of SiO2 102, the capacitance of the depleted P type thin layer and the capacitance of a depleted N substrate is obtained at that time. Since the capacitance of the depleted N substrate can be designed arbitrarily in a small value when donor concentration is lowered, a capacitance viewed from the electrode can also be reduced arbitrarily. The capacitance of potential in the depth direction under phi1, phi3 electrodes can be minimized arbitrarily when the donor concentration of the N substrate is lowered similarly. Signal charges transfer under the phi3 electrode on the right side of the phi2 electrode when phi1=phi2=0 and phi3 is brought to positive potential, and signal charges transfer under the phi1 electrode on the right side of the phi3 electrode when phi2=phi3=0 and phi1 is brought to positive potential.
