Filed: 1981-07-08
Abstract: PURPOSE:To exclude the resistance for control of voltage and to collect the unnecessary loss of electric power to utilize it effectively to other devices, by connecting a constant voltage circuit in series to a light emitting element driving part to control the light emitting element driving voltage. CONSTITUTION:A driving circuit consists of a light emitting element driving part including a light emitting element LD, a transistor Q1, a resistance R2, a diode D, a transistor TRQ2, a resistance R4 and an inverter I and a parallel control stabilized power supply P.C,P.S. The power supply P.C,P.S is connected to the return circuits of the element LD and the diode D to produce the voltage VO. As a result, the sum current (i) of the current i1 flowing to a TRQ1 and the element LD and the current i2 flowing to the TRQ2 and the diode D flows to the power supply P.C,P.S. Thus the electric power P=VO.i is produced to be utilized effectively as a power supply for other circuits. In such way, the electric power is collected.

Title: Image forming device
Inventor: OZEKI YUKIHIRO
IPC: G03G15/16
Filed: 1989-04-28
Abstract: PURPOSE:To always stably perform transfer to a transfer material in every size regardless of environment by performing constant-voltage control at newly set voltage in accordance with a detected current in the case that a transfer part is an image area. CONSTITUTION:A CPU 8 transmits a transfer-on signal to a power source 4, so that the constant-voltage control is performed by the power source 4. At the time of performing the constant-voltage control, a current detection circuit 9 detects the current at such a time and inputs the signal in the CPU 8. The CPU 8 which receives the signal converts the signal into an appropriate transfer voltage value by a voltage-current corresponding table previously held. The signal is transmitted to the power source 4, which newly starts the constant- voltage control at this voltage value. Thus, excellent transferring ability is always stably obtained regardless of the size of the transfer material in every environment.

Filed: 1990-04-25
Abstract: PURPOSE:To improve contrast without narrowing down the angle of visibility by setting a relation between the dimension of the diagonal of a screen and a dimension from the screen to a first mirror and the converging distance of a Fresnel lens to specified values. CONSTITUTION:When the diagonal of a screen 6 is set to S inches and a dimension A from the screen 6 to a first mirror 5 is set within 200+(S-40)X10mm, the converging distance of the Fresnel lens 7 is set within 4m in the range of 300mm from the center of the screen 6. In the case of satisfying this relation, the emission angle of unnecessary light reflected by the Fresnel lens 7 is made downward and gets out of the view. Therefore, the unnecessary light is reflected by the mirror 5 and the contrast is prevented from being lowered by emitting the light from the Fresnel lens 7 and making it incident on eyes.

Title: Exhaust gas heat exchanging method
Inventor: KASHIWAGI HIROSHI
IPC: F28F21/08
Filed: 1986-05-12
Abstract: PURPOSE:To enable stable recovery of heat from high temperature corrosive atmosphere exhaust gas, containing sodium sulfate and sodium carbonate, or potassium sulfate in a sodium recovery boiler for a long time, by a method wherein heat transfer tubes made of Ti or a heat transfer tubes made of a Ti based alloy, e.g., Ti-Pd, are used. CONSTITUTION:Exhaust gas, e.g., SOX, H2S and HCl, produced resulting from analysis of black liquid and partial combustion and containing sodium sulfate and sodium carbonate, or dust, e.g., potassium sulfate, is introduced to a heat exchanger 4. A heat transfer tube bundle 9, spanned between two headers 10 and 11 of a heat exchanger, is formed with heat transfer tubes, made of Ti or a Ti radical alloy, e.g., Ti-Pd, and this constitution results in remarkable prevention of the occurrence of usual corrosion by SOX and H2S through the presence of sodium sulfate and sodium carbonate or potassium sulfate, and in the possibility to use the heat transfer tube for a long time. Further, this constitution can reduce gap corrosion, occurring at a gap between the tubes and the two headers 10, 11 or a support plate 12 when steam is condensed on the surface of the heat transfer tube on the low temperature side, corrosion, occurring as a result of condensate producing an HCl solution, and corrosion on the high temperature side due to the use of a heat transfer tube made of Ti based alloy, e.g., Ti-Pd, and permits decrease of a rise in a price.

Abstract: PURPOSE: To increase not only the velocity but the efficiency of the character reading, by detecting the rectangular window frame through which the character information on the reading subject is read and then deciding the line direction of the character in accordance with the result of the above detection.  
     CONSTITUTION: The postal matter P is conveyed in the a-direction to receive the read scanning at the position of the reading part 1, and this output is supplied to the deciding part 20. At the part 20, the horizontal and vertical projections A and B are obtained for the window frame W of the matter P with a comparison given between the lengths of A and B. And in case B is longer than A, it is decided that the matter P is parallel to the longer direction of the frame W. On the other hand, a read scanning is given to the matter P arrived at the reading part 11, and this output is supplied to the recognizing part 30. At the part 30, the read character, i.e., the postal zone number N in this instance, is recognized by the outputs of the parts 20 and 11. Accordingly, the frame W is detected with its shape decided, and thus the describing direction of the number N can be decided. As a result, not only the reading velocity but the reading efficiency can be increased for the character.
