Title: Toner replenishing device
Inventor: WAKITA AKIKO
IPC: G03G15/08
Filed: 1992-04-21
Abstract: PURPOSE:To form the wall of toner supplied from the upstream side in a rotational direction, and to prevent the back flow of the toner supplied from the downstream side in the rotational direction to a toner storage part caused by pressure in the rotational direction and reduction in the supplying quantity of the toner by setting the toner supplying quantity of a toner replenishing member on the upstream side in the rotational direction larger than that of the toner replenishing member on the downstream side in the rotational direction with respect to a toner replenishing port. CONSTITUTION:The toner storage parts 32 and 33 are formed on both sides of the toner replenishing member 30. Stirring blades 35a and 35b and scraping up blades 36a and 36b are provided on respective toner storage parts 32 and 33. The width of the scooping part 42a of the scraping up blade 36a on the upstream side in the rotational direction of the toner replenishing member 30 is set larger than that of the scooping part 42b of the stirring blade 35b on the downstream side. The scraping up blades 36a and 36b are vertically moved by the rotation of the stirring blades 35a and 35b, and the scooping parts 42a and 42b scoop the toner. The wall of the toner can be made on the upstream side in the rotational direction of the toner replenishing member 31. The toner supplied from the scooping part 42b of an opposite side hits on the wall. The toner supplied from the upstream side can be never pushed back by the toner supplied from the downstream side.

Title: Manufacture of semiconductor substrate
Inventor: HAYAFUJI AKIO
IPC: H01L21/02
Filed: 1990-04-16
Abstract: PURPOSE:To manufacture a GaAs-on-Si substrate which does not cause a warp and a crack by a method wherein SiO2 is deposited, at room temperature, on the rear of the GaAs-on-Si substrate, this assembly is heat-treated and then cooled down to room temperature and the SiO2 is removed. CONSTITUTION:A GaAs layer 2 is grown on an Si substrate 1; a GaAs-on-Si substrate is obtained. Then, SiO2 3 is deposited on the rear of the substrate at 350 deg.C or lower, e.g. at room temperature; this assembly is heat-treated at 350 deg.C, e.g. at 360 deg.C, and, after that, is cooled down to room temperature; the SiO2 3 on the rear is removed. Since the coefficient of thermal expansion of the SiO2 3 is smaller than the coefficient of thermal expansion of Si in this case, the Si substrate is set to an inverse warp state at a heat treatment at 600 deg.C. When this assembly is cooled down to room temperature, a tensile stress decided by the difference in a coefficient of thermal expansion between GaAs and Si and by the difference in a room temperature between 350 deg.C and room temperature is left at the layer 2. However, since the layer 2 is plastic- deformed in the reverse warp state, a warp amount at room temperature is reduced as compared with a case where the SiO2 is not used, and it is not changed even when the SiO2 3 is removed. Consequently, it is possible to obtain a semiconductor substrate which does not contain a warp and a crack.

Title: Integrated light detecting/emitting device
Inventor: KARAUCHI ICHIROU
IPC: H01L23/48
Filed: 1990-04-16
Abstract: PURPOSE:To prevent any crosstalk caused by coupling among wirings from being produced by providing an electrode at a location adjoining to light detecting/emitting regions of a plurality of semiconductor devices formed into a straight line on a semiconductor substrate and oppositely to another electrode with respect to a straight line connecting central portions of the light detecting/emitting regions. CONSTITUTION:For integrated light detecting devices on a semiconductor substrate 1, electrodes 3 provided adjacent oppositely alternately with respect to a straight line connecting the central portions of the regions 2. Wirings from the electrodes 3 are connected to external wirings 5 around the light detecting device using a gold wire, and detection of photocurrents at a second location from the left and at the right end allows a ribbon fiber to be connected and displacement of the same to be formed. Thus, correction of the displacement is facilitated and a center adjustment can be performed with high accuracy. Further, wirings from the electrode 3 to the wiring 5 are taken from an adjacent region 2 one region apart and hence spatial redundancy is ensured to permit them to be laid substantially perpendicularly to each other. Hereby, electric capacities and coupling coefficients among the wirings are reduced and hence any crosstalk in a high frequency region can be reduced.

Title: Thermal transfer printer
Inventor: HORI YASUROU
IPC: B41J2/36
Filed: 1983-06-09
Abstract: PURPOSE:To make it possible to reduce an image printing time to 20-50%, by providing a means which detects whether divided currents having time amplitudes are flowed to at least one of heat generating elements in a thermal head or not and, when there is no heat generating element through which the current is flowed, stops the supply of the current having said time amplitude. CONSTITUTION:Flip-flop 12 and an AND element 13 are assembled between an address counter 2, a comparator 3, a time amplitude generator 5 and a shift register 8 to detect an ON signal relating to the supply of a current to each heat generating element 11 in a thermal head 10. When there is even one signal for turning the heat generating element, the rising of the signal enters CLK of the flip-flop 12 and the level (low level) of D is sent to Q to be converted to a low level while Q comes to a high level state. When Q is under the high level state, that is, there is no signal for turning the heat generating element ON, the AND element 13 outputs a high level and, therefore, the time amplitude generator 5 is stopped by this high level signal to complete recording corresponding to one line. As a result, a residual time to max. concn. can be shortened.

IPC: B60L15/20
Filed: 1980-07-24
Abstract: PURPOSE: To make it possibe to control the speed of a self-operating track, by simply accelerating or decelerating manually by means of storing the present speed signal of the track when it conforms to a certain relation with the previously stored speed signal.  
     CONSTITUTION: When a main switch SW 1  is closed, a predetermined speed A is stored in a memory 8, and the cart runs at said speed. A memory 4 memorizes a speed signal of the track given by a counter 3 and at the same time transmits the speed signal memorized previous time to a comparator 6 every time a clock pulse CL 1  is given. The comparator 6 stores the present speed signal in the memory 8 when said signal is larger than the signal transmitted by the memory 4. Thus, the track runs at the speed stored in the memory 8. When a decelerating switch SW 2  is closed, the initial speed A is stored in the memory 8.
