Title: Laser scanner unit for laser printer
Inventor: ICHIKAWA TOSHIYUKI
IPC: H04N1/113
Filed: 1989-07-28
Abstract: PURPOSE:To accurately detect a printing starting position by receiving reflected light obtained by reflecting light output from a light emitting element by a polygon mirror by means of a photodetector when a laser beam arrives at a starting position and detecting the printing starting position based on the output from the photodetector. CONSTITUTION:The output obtained when the reflected light is received by the photodetector 148 which receives the reflected light obtained by reflecting the light output from the light emitting element 147 by the polygon mirror 144 is supplied to a laser diode control circuit 142. When the output from the photodetector 148 is inputted, the laser diode control circuit 142 outputs a print ing starting signal to an I/O port. Therefore, even when the intensity of the laser beam which is made to scan by changing the output level of the laser light of a laser diode 141 is changed, the light emitting element 147 is kept constant regardless of the change of the output level of the laser light. Thus, the photodetector 148 always surely receives the reflected light in such timing that the laser beam arrives at the set starting position for deciding the printing starting position and the printing starting position is detected.

Inventor: MOORISU GURUNIE
IPC: F25J3/00
Filed: 1990-07-26
Abstract: PURPOSE: To economically restart the operation of a main heat exchanger, by positioning the heat exchanger in such a way that the exchanger is at least partially dipped in a liquid when the operation of an air distillation double column is stopped and, at the same time, providing an auxiliary heat exchanger suitable for only guaranteeing the vaporization of the liquid. CONSTITUTION: When the operation of a facility is stopped, a liquid rises to a level N1 and a heat exchanger 7 is dipped in the liquid. When the operation is restarted, a pump 15 raises the liquid to an upper liquid receiver 25A, because a valve 26B is closed and another valve 26A is opened. Part of the flow rate is vaporized and the liquid gradually descends in the liquid reservoir of a low-pressure column. When the liquid nearly returns to a level N, the heat exchanger 7 is newly actuated. When the operation is restarted, in addition, a valve 27B is closed and the pump 15 raises the liquid in a supply box 27. As a result, an overpressure is generated in the box 27 and allows the oxygen vaporized in an auxiliary heat exchanger 20B to exceed the pressure of an underlying liquid bath.  The liquid gradually descends in the liquid reservoir of the low-pressure column together with the pressure in the supply box 27 and, when the liquid nearly returns to the level N, the heat exchanger 7 is restarted and the valve 27B is opened.

Abstract: PURPOSE:To shorten analysis time by providing a time chart memory in order to analyze a unit consisting of plural samples and setting the same at the longest time in the analysis items within said unit without setting the same at the longest time of all the items. CONSTITUTION:Even if there are; for example, 32 items, in the entire analysis items of an analyzing apparatus, the four items among the same are analyzed as one unit. The operation time of the analysis process is preset in the time chart memory 3 at the analysis time of the shortest analysis time of said analyzing apparatus. Clocks are generated from a reference signal generator 4 and a signal is fed through a comparator 6 and a control system 2 to a unit system 1 to operate the respective units of sample distribution 1a, reagent supply 1b, liquid feed 1c and reaction 1d. The operation of; for example, 1d of the unit is delayed at this time according to the content of a delay time table 11 so as to meet the longest time (T*) among the analysis items within the unit. Since the analysis is made in compliance with the longest time (T*) within the unit not in compliance with the longest time (T0) of the entire analysis items in the above-mentioned manner, the total analysis time is shortened.

Abstract: PROBLEM TO BE SOLVED: To obtain an electrically stable ground by preventing a displacement current from flowing to the ground by providing a conductive layer having a potential which is different from the ground potential in an insulating substrate or on the surface of the substrate on which no semiconductor element is mounted. SOLUTION: Since an emitter circuit 502 contained in a package is electrically connected to an inner-layer emitter circuit 510 and an insulating substrate 505 is interposed between the circuit 510 and a ground surface 506 connected to a ground 509, the circuit 510 is connected to a ground 607 through an inner emitter-to-ground capacitance 603. In addition, since the emitter circuit 510 has the insulating substrate 505 between a collector circuit 503 contained in the package and the ground surface 506, the circuit has a collector-to-inner layer emitter capacity 602 between the circuits 503 and 510. Therefore, such an inverter device that has no possibility of malfunctioning a controller having another electronic circuit commonly using the ground 509 can be obtained, because no displacement current flows.

Abstract: PURPOSE:To simultaneously execute an access to a two-dimensional data on a memory space by constituting the titled circuit so that rite of a data or read- out of a data can be executed to and from all memory elements that have been addressed by the first and the second address means, by an input/output means. CONSTITUTION:16-bit data iO00-iO33 from a memory array, which have been addressed and read out are inputted to a tri-state buffer 103 with a rotation. As for S1 and S0 inputs of the buffer 103, Ay is the lower 2 bits (1) of Ay, and in the same way, Ax is the lower 2 bits (11) of Ax, therefore, for instance, iO00 which has been inputted to A0 of the buffer 103 is outputted to B2, inputted to A0 of a buffer 103' and outputted to B1(da9). At present, if a THRU signals 116 is '0', it is outputted to a bit of a data bus of a CPU through a buffer 109. Accordingly, by setting a write signal, the inverse of WR117 to '0', a matrix data of 4X4 can be written simultaneously to a memory array 110.
