Title: Focusing system of zoom lens by all-system movement
Inventor: MIYAMAE HIROSHI
IPC: G02B15/22
Filed: 1982-03-04
Abstract: PURPOSE:To reduce variation in aberration, to decrease the diameter of a front lens, and to simplify a cam mechanism, by moving in one body the whole zoom  lens system for focusing. CONSTITUTION:The 2nd and the 1st group lenses are moved in one body to perform focusing. Consequently, there is not any relative shift in arrangement among lens groups in the zoom lens system, so variation in aberration is reduced. Further, the 2nd group is also moved together with the 1st group, so the slanting angle of a main light beam is reduced with constant image height and its height from an optical axis when it passes through the 1st group is decreased to reduce the external diameter of the front lens. In addition, this is applicable to all types of zoom lenses and its flexibility is increased greatly. Further, they are moved in one body, so the cam mechanism is simplified.

IPC: H01S3/038
Filed: 1986-02-19
Abstract: PURPOSE:To prevent glow discharge and to obtain a laser generating unit with minimized capacitance of a power supply, by dividing one of glow discharge electrodes in an optical resonator into a plurality of electrode sections by means of ballast resistors, further separating them into a group of electrode sections for preliminary discharge and a group for main discharge and providing power supply devices respectively for the two groups of electrode sections. CONSTITUTION:A main power supply device 4, which supplies low-voltage and high- current power to discharge electrodes 1, is connected through ballast resistances (r) for anode electrodes 1-2, integrated and grounded through a switching circuit 6 and a current transformer 7. A control circuit 8 detects current from the current transformer 7 and constant-current controls so as to regulate the current supplied by the main power supply 4 for control the intensity of glow discharge 10. Further, the control circuit 8 provides a mode command to open or close the switching circuit 6 continuously or in pulsing manner. A voltage of Vs=Vg+Vb is applied between a cathode electrode 1-1 and a trigger power supply 1-3 for starting and maintaining glow discharge 10-2. This preliminary glow discharge 10-2 is for helping ignition of the main glow discharge 10-2 and may be such a weak one that (r)<<R for that purpose. In this manner, the capacitance of each power supply can be minimized and the size can be reduced.

Inventor: TANAKA MAKOTO
IPC: H01L21/66
Filed: 1982-03-01
Abstract: PURPOSE:To eliminate working error by previously determining a number of continuous chips per die on the same wafer, wafer test is carried out at a time for each die and a marker for scribe is provided at the desired area when all chips has passed the test. CONSTITUTION:In case of continuously forming chips 3 on the same semiconductor wafer, these chips are grouped along the boundary 1 which will become the scribe line.

Filed: 1990-02-14
Abstract: PURPOSE:To release undesired synchronization lock or to prevent mis-locking by revising a threshold level of a synchronization acquisition circuit optionally and automatically in response to a reception state or a noise level of a signal. CONSTITUTION:A BPF 20 receives a reception signal and outputs only a signal of a spread spectrum signal band to a multiplier 22. A correlation output is outputted from the multiplier 22 receiving a PN code from a pseudo noise generator 28. An LPF 24 gives only a component of a data band to an integration device 26, which applies integration processing to the correlation output for one period of the PN code and the integration output is fed to a peak hold circuit 36 and an average value calculation circuit 38. The circuit 36 receiving the correlation value holds a maximum correlation value C2 as rMAX and the circuit 38 divides the integration device output by bit number of the PN code for each period of the PN code to calculate and output the correlation output rN, per bit unit. A threshold level decision circuit 34 decides a threshold level rTH based on the inputted value and one period signal from a search control circuit 40.

Abstract: PURPOSE:To maintain the accurate operation of a clutch by providing a ball holder rotatable integrally with a drive shaft and axially slidable between a press board and a driven rotor. CONSTITUTION:A driven rotor 6 is rotatably provided on a drive shaft 3.

Title: Total optical image signal processing device
Inventor: OTANI HIROYUKI
IPC: G01S3/782
Filed: 1988-02-16
Abstract: PURPOSE:To preserve the coherent characteristic and incident direction of incident light so that the light can be utilized by spacially changing the amplification factor by exciting a gain medium by pumping light and projecting input light on the excited gain medium, thereby generating a stimulated emission. CONSTITUTION:The gain medium 15 of an amplifier 1 consists of the dye 4-(N, N-diethylamino)-4'-nitrostilbene doped into a thin polycarbonate film. The excited molecules execute the heat release and attain the state of a level 2 when the dye is excited from the level 1 of the ground state to a level 3 by the pumping light. The gain medium activated in such a manner generates the stimulated emission by the incident light of the energy difference between the level 1 and the level 2, thus amplifying the incident light. The incident light and the amplified light have the same wavelength and phase and the coherent property is maintained before and after the amplification. Since the level 2 has a certain width, the amplification of the prescribed wavelength region is possible.

Title: Enclosed type rotary compressor
Inventor: SUDOU MASAYASU
IPC: F04C27/00
Filed: 1982-03-05
Abstract: PURPOSE:To prevent leakage of high-pressure gas into a cylinder chamber, by applying a high pressure of discharge gas to the back surface of a retainer plate disposed between a cylinder and an upper bearing or a lower bearing, and thereby urging the retainer plate onto the end face of a roller. CONSTITUTION:Discharge pressure in a case is carried into a pressurizing groove 20 from a communicating port 21 so that it is applied as a back pressure to the upper surface of a retainer plate 18. Resultantly, the retainer plate 18 located on the side of a suction chamber 14 of a cylinder 5 is urged downward by the differential pressure of the back pressure and the suction pressure. On the side of a compression chamber 13, on the other hand, the retainer plate 18 is depressed also downward by the differential pressure of the back pressure and the pressure in the compression chamber 13 since pressure in the compression chamber 13 is lower than the back pressure until it is raised to the discharge pressure. Therefore, the retainer plate 18 is deflected to a position where it is held in contact with the end face of a roller as shown by the dotted line in the drawing, so that the clearance C at the end face of the roller can be reduced.

Abstract: PURPOSE:To evade a lacking of an output picture or a trouble outputting the same picture data to plural sheets of output paper by executing reduced variable magnifying processing for picture data when paper size is small, and then outputting the processed data to a picture output device. CONSTITUTION:When an output request for optional picture data is generated in a host computer 10, the computer 10 inquires paper size to be outputted to an I/O control part 1 in a laser beam printer 12. Whether paper size answered from the printer 12 is larger than the size of picture data requesting at its output at present or not, i.e., whether the data can be outputted or not, is judged. At the time of judging the disablement of output, known reduced variable magnifying processing such as thinning is executed so as to include the data in the paper size and the reduced picture data are transferred to the control part 1 in the printer 12 through a cable 13. In the printer 12, necessary picture converting processing is applied to the received picture data and the processed data are printed out from an image forming part 8.
