Patent JP-S60220268-A (JP)
Title: Built-up packing
Inventor: UIRUHERUMU SHIYUMITSUTO
IPC: F16J15/3256
Filed: 1985-02-15
Abstract: A cartridge seal has concentric outer and inner rings which snap together relatively rotatably to form the cartridge. Each ring has a generally L-shaped, inner axial profile with generally axial and radial legs thereof oppositely disposed. A sealing lip on the radial leg of the outer ring sealingly bears against an abutment surface on the radial leg of the inner ring to accommodate radial excursions during relative rotation therebetween. At least the radial leg of the inner ring is made of a material, for example metal, which conducts heat well. Frictional heat of the sealing lip against the abutment upon relative rotation is thus conducted to the surface of the radial leg of the inner ring opposite the abutment surface for dissipation. Heat dissipation is further improved with depressions in the opposite surface for expanding its surface area and, if the depressions are radial grooves, circulating a fluid medium wetting the surface to carry away the dissipated heat.

Title: Constant current circuit
Inventor: OOGAWARA TOSHINORI
IPC: H03F3/34
Filed: 1982-02-24
Abstract: PURPOSE:To obtain a stable constant current circuit, by setting an emitter area of a transistor(TR) to which a constant current is applied from an FET constituting a constant current source nd a TR forming a current mirror circuit so as to eliminate temperature dependancy. CONSTITUTION:A constant current I1 flows to  a TRQ1 by a constant current circuit formed with a junction FETQ3. A current I2 flowing to the load is determined by an equation, VBE2+R.I2=VBE1, where VBE1, VBE2 are base-to-emitter voltages of two TRsQ1, Q2 forming the current mirror circuit and R is a resistor.  In obtaining the relation satisfying conditions (equationI)so that the temperature dependancy of an emitter current I2 is zero at ambient temperature T=T0 from the equation, equation II is obtained, where A1, A2 are the emitter effective areas of the TRs. The effect of temperature is eliminated by determining the emitter areas so as to satisfy equation II.

Title: Nuclear reaction inducing method
Inventor: IWAMURA YASUHIRO
IPC: G21B3/00
Filed: 1998-02-10
Abstract: PROBLEM TO BE SOLVED: To diffuse deuterium in a structure body so as to induce nuclear reaction by heightening deuterium pressure on one side of a hydrogen storage metal or alloy structure to store deuterium, and putting the other side in a vacuum or relatively low pressure state. SOLUTION: An electrolyte 11 is stored inside an electrolytic cell 13 of a nuclear reaction device 10, and a vacuum chamber 15 is partitioned in a vacuum container 17. A palladium electrode 21 is fitted to a partition plate 19 between the electrolytic cell 13 and vacuum container 17 and communicated with a negative terminal of a power source 23. Opposed to this, a positive electrode of platinum is provided in the electrolyte 11 and communicated with a positive terminal of the power source 23. When a current flows between the palladium electrode 21 and positive electrode 25 from the power source 23, heavy water is electrolyzed. When this current is increased, the diffusion quantity of deuterium is increased, and the deuterium gas quantity discharged from the palladium electrode 21 is increased to increase the pressure of the vacuum chamber 15.  The concentration gradient of deuterium of the palladium electrode 21 is therefore enlarged to induce nuclear reaction.

Title: Detection of rotating speed
Inventor: YOKOYAMA SHIYOUTAROU
IPC: G01P3/489
Filed: 1982-02-23
Abstract: PURPOSE:To improve the quick response of the detection by determining the sum of (n) sets of data which are memorized in a sequential time series for a specified time at an interval of 1/n rotation while each set of data memorized is updated in a sequential shift at an interval of 1/n rotation. CONSTITUTION:An example of n=8 is mentioned. A reference pulse P of a fixed frequency is counted with a counter 10 and the counts pm are sent to a register 11 with the falling of an output signal of a rotary sensor. Then, the counter is cleared, and the pm is time required of 1/n=1/8 rotation. Registers 11-17 are arranged in the number n-1=8-1=7 and include pm-1, pm-2...pm-7 which are shifted simultaneously at each falling of an output signal of the rotary sensor and transferred to the sybsequent stage. Simultaneously with the shift, the data pm, pm-1,...pm-7 are sent to an adder 19 to determine the sum Pm of the data. When the constant K is divided by the sum, the rotating speed N'=K/Pm is determined. Thus, the calculation of the speed can be done stably.

Filed: 1982-02-25
Abstract: PURPOSE:To enable to obtain a detector operated at a low voltage in a roome temperature by a method wherein a P type Si single crystal of superhigh specific resistance manufactured by a particular method is utilized for a semiconductor radiation detector. CONSTITUTION:On the upper surface of the P type Si substrate 1 of superhigh specific resistance at 10,000OMEGA cm or more manufactured of high purity monosilane purified by using a molecular sieve, an N region 3 is formed by the thermal diffusion of donor impurity with an oxide film 2 as a mask, and an electrode 4 is ohmic-joined thereon.

Title: Method of measuring crystal defect
Inventor: NISHIZAWA MASATO
IPC: H01L21/66
Filed: 1988-02-10
Abstract: PURPOSE:To detect depth of a region where crystal defects are present in a nondestructive manner, by forming a photodiode in a part of a semiconductor wafer, applying light thereto to test dependency of photoelectric current on optical wavelength and obtaining an optical wavelength at which a point of inflection is given in the characteristic line representing relation between optical wavelength and photoelectric current. CONSTITUTION:A photodiode 7 referred to as a PIN photodiode is produced and a reverse bias voltage of several tens volts is applied thereto. Thereby an intrinsic layer with a thickness of 50mum completely becomes a depletion layer. All the carriers generated in the depletion layer move by drift to define photoelectric current 12. Light 8 is applied to the P<+> layer side of the photodiode 7. The photodiode 7 is irradiated with monochromatic light with a certain intensity from a spectroscope. Current (i) flowing through the photodiode 7 on this occasion is measured. Since there is recombination center of carriers in a defective layer 10, any carrier generated within the defective layer is absorbed by the defects and photoelectric current is decreased. This decreasing effect becomes stronger as a wavelength is larger.
