Patent JP-S59132687-A (JP)
Title: Semiconductor photo detecting element
Inventor: TORIKAI TOSHITAKA
IPC: H01L31/0352
Filed: 1983-01-20
Abstract: PURPOSE:To obtain an APD of low noise wherein the rate of ionization is increased sufficiently by a method wherein the first semiconductor layer having a thickness less than a specific value and the second conductor layer having a forbidden band width larger than the thickness and a thickness less than a specific value are laminated alternately by double layer and more respectively. CONSTITUTION:When the thicknesses of GaAs layers 1 and Al0.5Ca0.5As layers 2 which have forbidden band widths Eg1 and Eg2 respectively and are laminated alternately are 300Angstrom  or less and 200Angstrom  or less respectively, the thickness of each layer 1 and 2 becomes approximately equal to the de Broglie wavelength of the electron. Electrons concentrated to a GaAs potential well layer 1 come to permeate through the Al0.5Ga0.5As layer 2 by tunnel effect, and accordingly quantized electron energy bands 3 and 4 are formed over each layer 1 and 2. The band doscontinuity on the side of a valence band is sufficiently small, and the interval of the energy band of formed holes is very small, therefore the interval can be approximated to the valence band of a bulk. Besides, this constitution makes the rate of electron ionization become much smaller than the rate of hole ionization.

Title: Separator for lead storage battery
Inventor: TAKAHASHI JIYUNJI
IPC: H01M50/414
Filed: 1982-01-20
Abstract: PURPOSE:To obtain a lead storage battery having a high initial performance and an excellent life performance by making ion exchange resins having grain diameters within the range of 0.1-1mum to be contained in a separator used for the battery. CONSTITUTION:Equal amounts of a strongly basic anion exchange resin (styrene system) and a strongly acidic cation exchange resin having grain diameters within the range of 0.1-1mum are mixed. Next, a separator plate for a lead storage battery is impregnated with the mixture to the extent of 0.3-5g per separator (corresponding to the surface area of 2dm<2>) of the solid part of the mixture. After such an impregnation work, drying work is performed at 50 deg.C so as to obtain a separator. By interposing the separator obtained in such a manner  as above between a positive plate and a negative plate, a lead battery with a high initial performance can be obtained.

Title: Light emitting diode firing circuit
Inventor: NAKANISHI KUNIMITSU
IPC: H05B44/00
Filed: 1985-01-18
Abstract: PURPOSE:To fire a light emitting diode with a power source voltage of 1.5V with a simple electronic circuit by supplying a discharging voltage together with a power source voltage to the diode when a switching circuit is closed. CONSTITUTION:When a power source 1 is turned ON and the base of a transistor 8 is set to LOW state by the time constant determined by a differentiator of a capacitor 7 and a resistor 5, the transistor 8 is turned ON, a transistor 9 is turned ON, the charged voltages of capacitors 6, 7 are discharged through the transistor 8. Thus, the voltage high than 1.7V applied with the discharging voltages of the capacitors 6, 7 to the voltage 1.5V of the power source 1 is supplied to a light emitting diode 2, thereby firing the diode 2.

Title: Lightweight rubber grip of multilayered structure and its production
Inventor: OKABE NAKAO
IPC: A63B60/06
Filed: 1994-01-28
Abstract: PURPOSE:To prevent cavities and chipping by foaming gases by providing the central part of a mandrel with fine pores and sucking away the gases generated in the inside through these fine pores. CONSTITUTION:The mandrel 4 is formed with a hole 16 of about 3 to 5mm diameter from the end on the side communicating with the outside near to its front end in its longitudinal direction and is bored with the plural fine pores 5 of about 0.5 to 1.0mm diameter penetrating to the surface of the mandrel 4. The hole 16 of the mandrel 4 is connected to a vacuum pump to suck the air in the case of formation of a sponge rubber layer 2 on the outer periphery of the mandrel 4 by metal molds. As a result, the foaming gases generated at the time of molding are vacuum sucked and expelled through the fine pores 5 and the hole 16. A sponge layer 2 free from the cavities and partial chipping is thereby formed.

Title: Combustion chamber for prechamber-installed internal combustion engine
Inventor: NOHIRA HIDETAKA
IPC: F02B23/00
Filed: 1978-01-30
Abstract: PURPOSE: To hasten a speed of combustion with a mixture made effectively stirring in bottom  of the combustion chamber, by providing a jet nozzle between the precombustion chamber and  the combustion chamber, so as to produce a jet stream, circumferentially swirling in the combustion chamber, and a jet stream, flowing axially downward along inner walls of the combustion  chamber.  
     CONSTITUTION: A jet stream A, from a first jet nozzle 49a, scavenges a spark plug electrode  27a to make an improvement of ignition, flowing downward to top surfaces of a low-positioned  piston 7 along inner wall surfaces of a combustion chamber 5, and colliding against top surfaces  of the piston to get turbulent. And a jet stream B, produced from a second jet nozzle 49b, causes  a turbulence in a top position of the combustion chamber 5. As the piston 7 goes upward, the  turbulency due to the jet stream A is propagated upward in the combustion chamber, with the  mixture made effectively stirring in the combustion chamber. Subsequently, with a spark discharged in a spark plug 27, a combustion is operated of the mixture, having a turbulence, in the combustion chamber. The jet streams A, B are both jetted from a precombustion chamber 47, with  a turbulence of the jet stream made remaining in the combustion chamber, thus causing an operation to hasten the combustion speed.

Title: Active device
Inventor: HATTA ATSUSHI
IPC: G02F1/1365
Filed: 1993-01-21
Abstract: PURPOSE:To prevent the peeling at the active part of an active device and to improve the durability and reliability thereof by making electrodes of the active part of the active drive thinner. CONSTITUTION:The third electrode 5 is provided so that the second electrode 4 is connected with the third electrode 5 and that a part of the first electrode 2 and a part of the third electrode 5 overlap each other via a ferroelectric substance 3.

That is, when the third electrode 5 having a thin film is provided only right above the active part while other parts are connected with the second electrode 4 having a thick film, the overall wiring resistance is almost the same as in the conventional structure, thereby arbitrarily making the third electrode 5 thinner. Then, the electrode sufficient in adhesion condition is formed on the upper part of the ferroelectric substance 3, thereby preventing the peeling which is caused by vibration.
