Title: Led print head
Inventor: SHINAHAMA MASAFUMI
IPC: B41J2/45
Filed: 1993-02-03
Abstract: PURPOSE:To realize a small-size LED print head by connecting LED driver ICs by inter-chip direct wire bonding. CONSTITUTION:LED driver IC chips 22 forming an LED print head require at least 8 input-side wirings 25 for every chip. A signal line of an electric current amount as small as several microamperes out of the 8 lines is connected by inter-chip direct wire bonding 6. In this manner, a circuit for connecting the LED driver IC chips 22 to each other can be eliminated from on a printed wiring board 23. An LED print head made of a small-width printed wiring board can be obtained. Therefore, a single-side printed wiring board of a small width and a low cost can be used by connecting the signal line by the inter-chip direct wire bonding 6. Thus, an LED print head can be reduced in size and lowered in cost.

Title: Method for reversing passive moving direction of double spin spaceship
Inventor: HAABAATO ESU FUONGU
IPC: G05D1/08
Filed: 1991-02-07
Abstract: PURPOSE: To provide a method for passively changing and inverting the orientation of a dual spin spacecraft provided with a supporting structure with respect to a gyro rotation rotor and a despun platform rotatably connected through a despin motor. CONSTITUTION: The rotational speed of a despun platform 20 is increased and the rotational speed of a rotor 16 is decreased. Thus, a despin motor is controlled to generate a transverse torque vertical to a spin axis by the product of inertia coupling. The produced transverse torque temporarily makes a spacecraft 10 unstable to make precession in the orientation of a horizontal rotation axis to make a spacecraft spin axis 12 to be the maximum moment of the inertia of the spacecraft. The spin axis makes precession toward a final inverted orientation passing through the orientation of the horizontal spin axis by additionally continuing the control.

Abstract: PURPOSE:To uniformly and quickly cool a pipe to be cooled at a low cost and to stop cooling at a prescribed temp., by pressurizing a cooling liquid with the gas in a tank and passing the cooling liquid then the pressurized gas through a quickly operating stop valve at a high velocity into the pipe to be cooled. CONSTITUTION:After the cooling liquid is introduced through a cooling liquid injection port 6 into the pressurized tank 1, the pressurized gas is introduced through a gas supply port 9 into the tank 1 to pressurize the inside of the tank to about 2-7kg/cm<2>G. The pipe 18 to be cooled such as seamless steel pipe is connected to the lower part of the tank 1 via a connecting pipe 2, the quickly operating stop valve 3 of a ball type, etc., a auxiliary running pipe 4 and a clamping jig 5. The above-mentioned valve 3 is then quickly opened. The cooling liquid is thereby passed in the pipe at a high flow rate of about >=10m/sec by which the pipe 18 is uniformly and quickly cooled in both the circumferential and axial directions thereof. The cooling liquid in the pipe 18 is thereafter discharged by the residual pressure of the pressurized gas in the tank 1 to drain the pipe inside, by which the cooling is stopped midway and the heat is restored with high efficiency.

Continuously, a clamper 16 is closed by working an air cylinder 18. Consequently, the final position of the dresser grinding wheel 2 in the abrasive cloth thickness direction is fixed by firmly constraining an elevation shaft 8 by the clamper 16.

Abstract: PURPOSE:To sort assuredly postage print surface through the mechanical processing by coating a rectangular detection mark on the postage print surface with a prescribed space and in parallel to each other. CONSTITUTION:A postal matter 3 is carried in the carrying direction 10, and a detection mark 5 on a postage stamp 4 passing above a detection window 11 is excited for the emission of light by an exciting light source 12. This emitted light is made incident to a detection part 14 through a lens 13 and converted into an electric signal corresponding to the quantity of the incident light. This electric signal is amplified by an amplifier 16 and delivered. The analog signal, i.e., the output of the amplifier 16 is sliced by a slice level circuit 18 at a prescribed slice level. Thus the binary coded bar code information is obtained in the form of the output of a comparator 17. This output of the comparator 17 actuates a clock synchronizing circuit 19, and said bar code information is fetched to a register 20 by the clock of the circuit 19. The fetched contents are decoded by the output of a decoder 21. The output of the decoder 21 decides various types of postal matters such as an ordinary mail an express mail etc.

Abstract: PROBLEM TO BE SOLVED: To restrain a slip between rolls and stock to a minimum by providing another driving unit besides a main roll driving unit on the output shaft of a differential gear connected to driving systems of A group and B group in a drum type roll. SOLUTION: The differential gear 3 is connected to driving shafts 2 and 1 of respective distributors 6 and 7 of A group 4 and B group 5 in the drum type roll having different roll diameters. The differential gear 3 is driven with a main motor 9 via a reduction gear 8. After stock is bitten into rolls 4 and 5, the differential gear 3 is operated to make the peripheral speed of A group 4 and B group 5 of rolls tune. The number of revolution of input shafts 1 and 2 is measured with revolution number detectors 12 and 13. The number of revolution at the time of biting stock and tuning to the differential gear 3 is stored in a sequence controller. Before a succeeding stock to be straightened is bitten, the difference in the rotary speed of rolls is corrected with a peripheral steed tuning motor 14 based on this value. Then, the peripheral speed of rolls is always allowed to tune.  Wear of rolls 4 and 5 is reduced and the generation of defects in the stock is prevented.
