Title: Optical scanner
Inventor: ITABASHI AKIHISA
IPC: G02B26/12
Filed: 1989-03-10
Abstract: PURPOSE:To effectively eliminate ununiformity of the diameter of a light spot in the sub- scanning direction which remains behind after eliminating a curvature of image and to execute a high density optical scan by controlling a very small oscillation of a cylindrical lens executed by an oscillating means by a second control means, and equalizing the diameter in the sub-scanning direction of the light spot by synchronizing with an optical scan executed by a deflection luminous flux. CONSTITUTION:A relation of an image forming position in the main scanning direction and the diameter of a light spot in the sub-scanning direction by a residual fluctuation is checked in advance, and an aperture, etc. are designed so that the maximum light spot diameter in the sub-scanning direction in the residual fluctuation becomes a target spot diameter 2W3. In this state, a cylindrical lens 2 is brought to very small oscillation by an oscillating means 9 so as to eliminate a fluctuation of the light spot diameter in the sub-scanning direction caused by the residual fluctuation. The oscillation quantity is related in advance to a synchronizing clock and stored in advance in a second control means 11, and the residual fluctuation is eliminated by controlling the oscillation of the cylindrical lens 2 by synchronizing with an optical scan by the oscillating means 9 in accordance with its storage contents. In such a way, since the light spot diameter in the sub-scanning direction can be equalized with high accuracy, the optical scan of a good quality can be executed.

Title: Loop detecting circuit
Inventor: KUWANO MASAYA
IPC: H04M11/00
Filed: 1986-03-19
Abstract: PURPOSE:To lower the price and reduce the size by leading a loop detection output out of the light reception part of a photocoupler and reducing the current based on a light emitting diode. CONSTITUTION:An electronic sink circuit 4 flows a DC current, but does not flow an AC current. When a loop is closed, a smoothed voltage generated at a point D drives a transistor (TR) Q1. At the same time, this smoothed voltage drives a TR Q2 as well. When the TR Q2 operates, a current flows to the light emitting diode of the photocoupler PC4 and the TR side of the photocoupler P4 turns on, so that the loop detection output appearing a terminal OUT is held at LOW (0 V). Thus, the smoothed voltage is used as a loop detection voltage. At this time, the constant of a resistance R6 is so determined that a current flowing through the resistance R6 is much smaller than a current flowing through a resistance R6 and then there is no influence upon various characteristics of the electronic sink circuit 4. Further, the current capacity based on the light emitting diode of the photocoupler may be small.

Title: Photoelectric object detecting device
Inventor: IGARI MOTOO
IPC: G01B11/00
Filed: 1985-03-25
Abstract: PURPOSE:To reduce an error of distance measurement by slanting the light receiving face of a light spot position detecting element not face the photodetecting lens of a condensing device rightly, and at the same time, providing a trapping device of light reflected by the light receiving face of the light spot position detecting element on the inner face of a housing. CONSTITUTION:The light receiving face of a semiconductor position detecting element 4 (PSD) belonging to PIN type photodiode is slanted not to face the light receiving lens of a condensing device 3, and at the same time, a trapping device 8 of light reflected by the photodetecting face of PSD 4 is provided on the inner face of a housing 7. Thus, light reflected by the light receiving face of PSD 4 does not enter the photodetecting lens of the condensing device 3. Accordingly, light reflected by PSD 4 is not received again by PSD 4, and returning of light reflected by PSD 4 to PSD 4 is prevented by the trapping device 8. Thus, an error of distance measurement is reduced, and object detection can be made at high accuracy.

Title: Interruption control system
Inventor: TANZAWA YASUSHI
IPC: G06F13/24
Filed: 1989-03-13
Abstract: PURPOSE:To surely apply an interruption to a CPU from an I/O adaptor by inhibiting the interruptions given to the CPU before an access is given to a register contained in an adaptor of the CPU after the I/O adaptor is reset. CONSTITUTION:An I/O adaptor 2 is cleared in its reset (initialization) state, and an access flag 2e outputs an interruption inhibiting signal to an interruption control circuit 2. Therefore no interruption is produced to a CPU 1 under such conditions even if an interruption request is supplied to an interruption control circuit 2d with some interruption factor. If the CPU 1 gives an access to a register 2a, the flag 2e decodes the corresponding address signal to know that the flag 2e itself received an access and applies an interruption grant signal to the circuit 2d. Then an interruption can be supplied to the CPU 1. Thus a sure interruption is always supplied to the CPU 1 after the pre-processing of the CPU 1 is finished and after a jump table is produced in an interruption state.

Abstract: The display in a diffusion type electrochromic display device is turned off with high response by applying an A.C. input voltage having a frequency of one to ten times as high as the cut-off frequency. The diffusion type electrochromic display device is an EC display device which uses an EC composition consisting of an EC compound coloring in a reduced state and a solvent in which the solubility of the compound to the solvent is 10-2 mol/(100 g solvent) or more in a reduced state and 10-1 mol/(100 g solvent) or more in an oxidized state. The cut-off frequency is a critical frequency at a freqency higher than which the oxidization or reduction of the EC compound cannot follow the change in the input voltage, which is normally 20 to 50 Hz.

Then, the 3-line comb line filter decreases to half in dot disturbance and vertical color bleeding compared with a 2-line comb line filter. Thus, the high performance bomb line filter can be obtained.

Then heat conductive gas is introduced to the rear surface of the wafer 18 and, when the wafer 18 is cooled to a desired temperature, plasma is generated by electrically floating the elastic member 25 to treat the wafer 18 with the plasma. When the plasma treatment is completed, the generation of the plasma and supply of the heat conductive gas are stopped and the elastic member 25 is again set to the grounding potential. Then the wafer 18 is carried from the stage 11 after a positive voltage is applied to the stage 11 for a certain period of time.

Title: Room heater
Inventor: OKUNO MASAHARU
IPC: F24H7/04
Filed: 1988-03-15
Abstract: PURPOSE:To prevent accidents due to high temperature exhaust gas caused by faulty rotation of a rotor, or troubles of a draft fan, by shutting down operation of a combustion device when a temperature detected by a thermo-sensor exceeds a specified temperature during operation of the combustion device. CONSTITUTION:A forced draft fan 51 sucks the room air through an air inlet 12 into a combustion device 10, that causes the fuel gas coming out from a gas burner 20 to incinerate in the combustion device 10 in order to gain combustion heat. The contaminated air after combustion is exhaust outside the room from an exhaust port 11 connected to the combustion device 10 with a rotor 30. A thermo-sensor 15 is installed upstream of the exhaust port 11 located on the non-combustion side of the rotor 30 in the combustion device 10 to detect the exhaust gas temperature after heat-exchanging. For example, in case the temperature detected by the thermo-sensor 15 exceeds 100 deg.C, it is recognized as a fact that normal heat-exchanged does not take place, and the whole operation of a room heating device is shut down to prevent an accident such as a fire.

Abstract: PURPOSE: To stabilize the driving displacement of an objective lens by driving movable parts in the direction parallel with the optical axis of the objective lens by the cooperative action between a focusing coil and the magnets constituting a magnetic circuit part. CONSTITUTION: Respective coil parts and respective coil parts 32, 33 constituting a focusing coil 31 and a tracking coil 34 are constituted by forming rectangular coil patterns while etching copper foil stuck on a coil fitting plate 28 made of glass epoxy resin.
