Patent JP-H07240227-A (JP)
Title: Sealed lead-acid battery
Inventor: TERADA MASAYUKI
IPC: H01M10/06
Filed: 1994-02-25
Abstract: PURPOSE:To suppress the occurrence of heat loss without lowering the highly efficiently discharging property by setting the specific surface area of a positive electrode active material per weight and the weight ratio of a negative electrode active material to the weight of the positive electrode active material within prescribed ranges. CONSTITUTION:When the specific surface area of a positive electrode active material per weight is set to be a relatively high range, at 10-15 m<2>/g, the current density of the positive electrode plate becomes small. Due to that, overvoltage of the positive electrode plate during charging becomes low and oxygen gas generation from the positive electrode plate is suppressed. When the weight ratio of a negative electrode active material to the weight of the positive electrode active material is set to be a relatively low, at 0.5-0.7, the current density of the negative electrode plate to the positive electrode plate becomes high and load overvoltage becomes high. Due to that, the potential of the positive electrode plate lowers and oxygen gas generation from the positive electrode plate is suppressed.

Abstract: PURPOSE:To produce a large signal output by using a light source having a low luminance by providing a means for amplifying a signal output from an optoelectric transducer on an insulating substrate. CONSTITUTION:A gate oxide film 11 is formed on a polycrystalline silicon film (poly-Si) on an insulating substrate 1, and a gate electrode 2 is formed thereon. Then, the resistance of the electrode 12 is reduced, the upper poly-Si is patterned in the shape of the electrode 12, B<+> ions are implanted into a channel 10 in this state thereby to form a P-channel 20. Thereafter, the P- channel 2 is masked, P<+> ions are implanted thereto, thereby forming an N- channel. Thus, a signal amplifying thin film transistor 3 from an optoelectric transducer 6 is formed on the substrate 1. Thus, a large signal output can be obtained by employing the light source having a weak radiating light intensity.

Title: Processing method of silicon nitride ceramics
Inventor: HARANO KATSUKO
IPC: B23K26/00
Filed: 1995-02-16
Abstract: PURPOSE:To cut silicon nitride ceramics as a work piece with a high accuracy, smooth the surfaces thereof without exerting body influencing the material itself and raise the processing speed. CONSTITUTION:The surface of the silicon nitride ceramics 5 is processed by irradiating the surface with a later beam 2 having a wavelength in a range of 190 to 360nm. The adequate processing is executed by regulating the energy density to a range of 10<5> to 10<10>W/cm<2> in the case of continuous light and regulating the energy density per l pulse to a range of 10J/cm<2> to 10<3>J/cm<2> in the case of impulsive laser beams. The laser beam 2 is condensed by cylindrical lenses 3, 4 or a cylindrical mirror. As a result, the application range of the silicon nitride ceramics is widened to a field of structural materials to which the application of the silicon nitride ceramics is heretofore not possible for its difficulty in processing and high cost.

Title: Thermo-module
Inventor: KAWARADA ATSUSHI
IPC: H01L35/32
Filed: 1996-02-16
Abstract: PROBLEM TO BE SOLVED: To facilitate the attachments of small thermoelectric elements to a board, by using as the board disposed on one of the heat radiating and absorbing sides of a thermo-module a monoblock board covering the whole surface of the thermo-module, and by using as the board disposed on the other side a plurality of divided boards. SOLUTION: P-type and N-type thermoelectric elements 3 are arranged alternately at a fixed space on a divided board 1. For example, to every one divided board 1, the 18 pairs of thermoelectric elements 3, i.e., the 36 thermoelectric elements 3 are attached. In this case, since there are the 16 divided boards 1 in a thermo-module, the total number of the attached thermoelectric elements 3 is equal to 36×16=576. The faulty thermoelectric elements 3 are checked in the case of their attachments to each divided board 1. Aligning the 16 divided boards 1 having the arranged thermoelectric elements 3 thereon with another monoblock board 2 oppositely to each other, the divided boards 1 are soldered integrally with each other, attaching leading wires 4 to the elements 3.  Since there are arranged many very small thermoelectric elements 3, the thermal efficiency of the thermo-module is improved, and since each thermoelectric element 3 may be attached satisfatorily to each divided board 1, its attachment can be facilitated.

Abstract: PURPOSE:To discharge the heat of oil-pressure pilot valve to inside and outside of a driver room by selecting whether cooling air taken by a fan is taken from the outside or inside of driver room by opening or closing a wind plate and also selecting outlet ports likewise. CONSTITUTION:When the atmospheric temperature is high, a fan 9 is turned to introduce cooling air through a suction port 25 from outside of a driver room 1 into an air vent path 23. An oil-pressure pilot valve 7 and a stand 5 are cooled by the air, and the air is discharged from an outlet port 28 to the outside of the room 1.
