Title: Laser light source device
Inventor: TERAISHI KATSUHIRO
IPC: H01S5/00
Filed: 1987-06-01
Abstract: PURPOSE:To facilitate avoiding inclined light emission and emitting a light to the direction parallel to the upper surface or the lower surface of a single crystal by a method wherein the direction of the normal of the light emitting end surface of the single crystal is so controlled as to be inclined against the longitudinal direction of the light waveguide in the single crystal. CONSTITUTION:In a device employing the 2nd harmonic of a semiconductor laser as a light source, the crystal orientations 11 and 12 of a single crystal plate 1 are so controlled as to make the edge face 4 of the single crystal inclined by an angle 8 against the direction 7 perpendicular to a reference plane 6. In other words, by utilizing a refractive effect created when an inclined emitted light passes through the final single crystal plate edge surface, the highly interfering light parallel to the upper face or the lower surface of a package as a whole can be obtained and a laser light source of a relatively short wavelength range can be obtained.

Filed: 1998-05-20
Abstract: PROBLEM TO BE SOLVED: To prevent a filter cloth from being broken in about the middle and to surely remove the stuck dust, etc. SOLUTION: This method for regenerating a filter cloth consists in vertically extending and contracting a bag filter 13 directed downward to release the dust, etc., stuck to the inside. In this case, the bag filter 13 is contracted downward while sending air into it. The filter cloth for a dry filter-type dust collector is formed into a bag and contains the bag filter 13 for collecting dust, etc., and a woven fabric 15 formed by weaving the year 15A into a scrim and set outside the bag filter 13. The yarn 15A of the woven fabric 15 can be inclined at an angle of 45 deg. to the expanding direction of the filter medium. A filter cloth 21 can be arranged in the horizontal direction. The filter cloth 21 consists of a horizontally arranged bag filter 23 and a woven fabric 25A covering the bag filter 23. The yarn 25A of the filter cloth 25 is inclined to horizontal.

IPC: H01J35/08
Filed: 1983-07-28
Abstract: PURPOSE:To produce various primary X-rays having different wavelengths by installing plural different target element on a circular area of an anticathode installed in a sealed tubular bulb and using a driving mechanism for rotating the anticathode. CONSTITUTION:In the sealed tubular bulb 1 of an X-ray generator, a disk-like anticathode 21 having plural different target elements 21a-21h arranged in a circular form on its surface is installed facing a cathode 2 which discharges an electron beam 7.

Title: Quartz oscillating system
Inventor: HOSHI HIDEO
IPC: H03B5/32
Filed: 1979-10-26
Abstract: PURPOSE:To enable to cause stable oscillation simultaneously in different frequencies, by providing two sets of electrodes at the center of long and short sides of a quartz chip and oscillating it with two sets of oscillation circuits. CONSTITUTION:Oscillating electrodes 6a, 6b for short side longitudinal oscillation are located along the center line in parallel with a long side, and oscillation electrodes 6c, 6d for lond side oscillation are located along the center line in parallel with a short side. The reason of the location along the center line is to increase the efficiency since the stress at oscillation is greater at the center. Further, since two electrodes are located on one plane, the center part of each electrode is made narrower. By the ratio of short and long sides, the difference of two oscillation frequencies can considerably be made free. Thus, the temperature characteristics can be made flat over a broader range by logical operation to two types of signals obtained.

IPC: G11B11/105
Filed: 1995-05-12
Abstract: PURPOSE:To prevent the power of a main beam for recording/reproduction from becoming unstable by a return light from a magneto-optical disk and thereby to enable accurate detection of the power, by detecting that power. CONSTITUTION:A laser light transmitted through a beam splitter 13 is led to a sensor 12 through a microlens 14 and detected. A drive current of a laser diode 11 is regulated by a current based on an output signal of the sensor 12 so that the power of the emitted light of the diode 11 being detected be a set value. The laser light reflected on a slant 13a of the splitter 13 is converged on a magneto-optical disk 17 through an objective lens 16. When a laser beam of a recording power is applied to the disk 17, information is recorded on the disk 17 or erased therefrom, since a magnetic field is impressed on the disk 17 by a magnetic coil. When a laser beam of a reproducing power is applied, recorded information of the disk 17 is read out. According to this constitution, construction of the optical system for detection is simplified.

A light 5 emitted from the diode 2 is reflected on the alkali-etched surface 1a of the wafer 1 having an oblique crystalline angle to become a reflected light 6, which is received by the phototransistor 3, opto-electrically converted to a signal. This signal is sent to the processor 4 which discriminates the front or rear of the wafer from the state of the detected light amount. That is, if the wafer has a normal surface orientation, it is reflected toward a direction of an orientation flat part 1b, while in the case of reverse wafer, it is reflected reversely.

Abstract: PURPOSE:To prevent the deterioration of a lubricating oil and a refrigerant, by a method wherein in a high temperature-refrigeration circuit, a refrigerant suction pipe line from a cascade condenser is connected to the suction port of a compressor through an oil cooler for another compressor in a low temperature refrigeration circuit. CONSTITUTION:The title arrangement has a high temperature-refrigerant circuit A and a low temperature-refrigerant circuit B.

After that, the water in the refrigerant is removed in a drier 9, and the refrigerant is expanded by an expansion mechanism 8 and led to a cascade condenser 5, and discharged from the condenser 5, following which the whole of the refrigerant is passed through an oil cooler 21 for a compressor 2 in a low temperature refrigerant circuit B and is returned to the compressor 1 again, and in such a way, the refrigerant is circulated. On the other hand, the low temperature refrigerant circuit B is composed so that another refrigerant is circulated therein. As the result of it, in the high temperature refrigerant circuit A, the compressor 1 can be fully cooled, and in the low temperature refrigerant circuit B, the lubricating oil for compressor 2 can be lowered in temperature, and thus the temperature rise of both the refrigerant and the compressor-lubricating oil is prevented, and the deterioration thereof can be prevented.

Abstract: PROBLEM TO BE SOLVED: To prevent the excessive reduction of pressure without using an acceleration sensor nor pressure reduction sensor by setting a pressure-reduction time in response to a ratio of the time, during which a differential value of the detecting signal of a wheel speed sensor at the predetermined value or less is detected, within a range retroactive to the predetermined time. SOLUTION: In a brake liquid pressure control device, a differential value of the wheel speed becomes unstable at a stage before the slip ratio exceeds a lock judgment reference value, and as this unstable time is longer, the brake liquid pressure control device shows the tendency of lock. A controller 65 sets the pressure-reduction time in response to the ratio of the time, during which the differential value of the detecting signal of wheel speed sensors 64b, 64d at the predetermined value or less is detected, within a range retroactive to the predetermined time. Normally closed solenoid valves 24b, 24d of a liquid pressure control unit 63 are driven during the set pressure-reduction time so as to reduce the brake liquid pressure of wheel cylinders 4b, 4d of rear wheels with the normally closed solenoid valves 24b, 24d and flow valves 9b, 9d.
