Patent JP-S58214821-A (JP)
Title: Semiconductor photodetector
Inventor: KAMAZAKI KEIJI
IPC: G01J1/44
Filed: 1982-06-07
Abstract: PURPOSE:To achieve a higher speed of a switching response by connecting the series connection of a photo diode reversely biased and a resistor to a gate of an FET. CONSTITUTION:When light irradiates a photo diode (PD) 12 reversely biased, light current flows through a series circuit of the PD 12 and a resistor 13. At this point, as the gate voltage of an FET 11 rises with a voltage drop in the resistor 13 an exceeds the threshold voltage, a load current flows through the FET 11. Light current of the PD 12 is almost proportional to the quantity of incident light of the PD 12 and the gate voltage varies. The load current flowing through the FET 11 is controlled with the gate voltage and then with an incident light of the PD 12.

Title: Control of fuel-battery voltage
Inventor: MACHIDA TAKEHIKO
IPC: H02J3/38
Filed: 1979-07-31
Abstract: PURPOSE:To avoid an inrush current during the starting of separately-excited magnet inverter by means of a simple equipment, by changing the inert-gas concentration in a battery through the adjustment of purge-gas flow rate, and thus controlling the voltage. CONSTITUTION:The drive of a motor 16 changes the opening degree of a damper 15, which determines the flow rate of purge gas. A part of air rich in an inert gas, which is ejected from a battery, and fresh air are mixed and supplied into the battery. For example, if the opening degree of the damper 15 is reduced to lower the flow rate of the purge gas, the amount of air in a pipe 12 is increased, and therefore, the inert-gas concentration in the battery is increased. As a resutl, the ratio of output voltage to a given output current is increased. Consequently, an inrush current during the starting of a inverter 2 can be avoided and an efficient operation can be achieved, when an alternating-current system, and a fuel-cell generation- system which is a combination of the fuel cell 1 and the separately-excited magnet inverter 2, are put into a parallel operation.

Abstract: PROBLEM TO BE SOLVED: To easily calibrate a particle measuring device using a laser Doppler current meter for measuring the shape of a particle. SOLUTION: A laser beam passing through the first cross region M1 which is a measurement region is again crossed by condensing lenses 21, 22 to form the second cross region M2. The cross region M2 is expanded by a magnifying lens 23. An optical fiber 24 is moved nearby from afar and is set at the position where no AC component is generated. The size of the incidence section of the optical fiber 24 can be equivalently matched with the interval of interference fringes, and the absolute value of the shape of a particle can be obtained.

Title: Small x-ray source
Inventor: KOYANAGI KEIJI
IPC: H01J35/16
Filed: 1995-03-31
Abstract: PURPOSE: To prevent infection by body fluids when using a small X-ray source for a plurality of patients, while securing economy and maintainability, by designing a power supply means and a vacuum container so that they are freely connected to and disconnected from each other both mechanically and electrically. CONSTITUTION: A power supply means (consisting of a power supply 31 and a housing 2 having a female connector 22a) and a vacuum container 1 are designed to be freely connected to and disconnected from each other, both mechanically and electrically. The container 1 can then be separated from and connected to the housing 2 readily. Therefore the portion of the vacuum container 1 (capillary 14) for insertion into the body of a patient can be made one exclusively for use with the specific patient. Also, even for the specific patient the size of a target 15 sometimes need be varied depending on the shape and size of a subject 6 for treatment. For a large subject for treatment, for example, a large target 15 is used, and for a small subject for treatment a small target 15 is used. Even in that case the power supply device 31 and the housing 2 (power supply means) need not be varied.

Filed: 1992-04-17
Abstract: PURPOSE:To comparatively low inhibit production cost and to diminish heat evolution and contamination by repeating a crushing stage at a plurality of times by a pressure roller device and there after and grinding the flaky raw material produced in the crushing stage by a flake breaker to pulverize the same. CONSTITUTION:A raw material crushed by a pair of pressure rollers 6A, 6B is compressed and becomes a corrugated flaky shape and then is discharged to a tank 1 of the raw material. A crushing stage is repeated at a plurality of times. At a point of time when the raw material is sufficiently crushed, the compressed flaky raw material is supplied to a flake breaker 7 and crushed by the blades rotated at high velocity to produce fine powder. The pulverized raw material is sieved by a screening device 8 and required fine powder is discharged from an outlet 10. Thereby fine powder is produced at comparatively low cost without necessitating freeze grinding and a freeze drying stage. Further heat evolution and contamination are diminished and good-quality fine powder is obtained.

Title: Optical information reader
Inventor: TOUFUKU ISAO
IPC: H04N1/028
Filed: 1979-07-30
Abstract: PURPOSE:To prevent destruction of a filter and remove needless infrared rays, by dispersing the heat capacity absorbed by each filter so that the heat capacity may be the heat allowable value or less of each filter by combining plural filters different in absorptivity in the infrared region. CONSTITUTION:Three heat ray absorbing filters 2, 3 and 4 are arranged in order from the side of illumination light source 1, and form 5 is arranged as a read object in back of them. When absorption coefficients alpha2, alpha3, and alpha4 of filters 2, 3, and 4 are denoted as 3/10, 3/7, and 3/4 respectively, the overall infrared dose reaching form 5 becomes the 1/10 of the incident overall infrared dose, and the rest 9/10 of the overall infrared dose are absorbed by filters 2, 3 and 4. The infrared dose absorbed by each of filters 2, 3 and 4 becomes the 3/10 of the incident overall infrared dose, and as the result, the incident infrared dose is dispersed and absorbed equally, and infrared rays can be shielded approximately uniformly.

Title: Positioning control system for magnetic head
Inventor: NAKAMURA MASAO
IPC: G11B21/08
Filed: 1987-04-21
Abstract: PURPOSE:To improve settling characteristics at the time of positioning of a magnetic head by controlling speed mode following an optimum curve out of plural speed profile curves selected in accordance with measured traffic volume. CONSTITUTION:When there is no offtrack, the center line CL of the magnetic head 3 is positioned on a position coincident with the end point A0 of a reference profile curve (PL) A. When a cylinder of a magnetic disk 2 is shifted from a reference position to the inside at the time of offtrack, the head 3 is positioned on a position shifted from the end point A0 by a distance (f), so that speed mode control operation can be allowed to follow a 1st correcting PLB. Consequently, the moving distance of the head 3 is a distance (e) from the end point B0 of a curve B to the center line CL. Since e<f is formed, the settling time can be shortened. When the cylinder is shifted from the reference position to the outside, control following a 2nd correcting PLC is executed and a moving distance (g) at the time of correction is smaller than a distance (h) between the end point A0 and the center line CL.
