Title: Dry planographic continuous printing method and apparatus
Inventor: TAKEUCHI SATOSHI
IPC: B41F7/00
Filed: 1988-04-18
Abstract: PURPOSE:To dispense with the control of an ink thickness and a drying process after printing while achieving miniaturization and wt. reduction, by superposing the ink layer of an ink film on the surface of a plate to transfer the same only to the oleophylic part being the printing image part on the surface of the plate. CONSTITUTION:An ink layer 2 is not flowable at ambient temp. and develops adhesiveness by heating and/or pressurization. A plate material is prepared by forming an oil repellent layer 5 to the surface of a support 3 through a conductive layer 4 and the oil repellent layer 5 is destructed and removed by a discharge needle 6 to form a printing image part 7 being an oleophylic part. An ink film is superposed on the surface of a plate and heated and/or pressurized to allow the ink layer 2 to develop adhesiveness and, when the support 1 is released, the ink layer is transferred to the surface of the plate while the ink layer of a non-printing image area 5 is not transferred to be left on the support 1 as a residual ink layer 8 and an ink image 9 is formed on the surface of the plate. Continuously, a material 10 to be printed is superposed on the surface of the plate and heated and/or pressurized to transfer the ink image 9 to the material 10 to be printed to complete printing.
Patent JP-S60235995-A (JP)
Title: Heat exchanger
Inventor: KIDO OSAO
IPC: F28F1/32
Filed: 1984-05-10
Abstract: PURPOSE:To contrive a higher heat exchanger performance without reducing a turbulent flow accelerating effect produced by a refrigerant pipe, by a construction wherein the cutting and raising direction of cut-and-raised pieces provided on plate form fins is set to accord with the stream line direction of air flow in the vicinity of a refrigerant pipe. CONSTITUTION:Since the plate form fins 5 are divided by the cut-and-raised pieces 7, enhancement of the coefficient of heat transfer can be contrived through a boundary-layer leading edge effect, and since the stream line direction 8 of air flow accords with the direction of the cut-and-raised piece 7 at the position of each of the pieces 7, the direction of the stream line 8 is not changed by the pieces 7, and the turbulence of air flows generated by the refrigerant pipes 6 is maintained, so that the turbulence accelerating effect is not reduced. Accordingly, the coefficient heat transfer is markedly enhanced by the boundary- layer leading edge effect produced by providing the fins 5 with the pieces 7, and the turbulent flow accelerating effect is not reduced through straightening of the turbulence of the air flows generated by the refrigerant pipes 6, so that a marked increase in coefficient of heat transfer can be contrived.

Abstract: PURPOSE:To allow the inching control easily by reading the regulating data of the oil pressure power responding to the engine rotation frequency to the accelerator operation amount from a memory device, and regulating and controlling a releasing capacity regulating device depending on the regulating data. CONSTITUTION:A controller 29 calculates the operation amount of an accelerator pedal 10 from the signal of an accelerator operation amount sensor 28, and at the same time, a regulating data of the oil pressure power responding to the rotation frequency of an engine 1 to the operation amount is red from a memory device, depending on which, the releasing amount of a charge pump 4 is controlled through a motor 17b for regulation, an inching lever 20, and a reducing valve 17, so that the generation of the oil pressure responding to the engine rotation frequency is transferred to the higher engine rotation side as the accelerator operation amount is increased. And when the accelator pedal 10 is not operated, the charge pump 4 is regulated and controlled to generate the oil pressure power at the higher engine rotation area. In such a way, an inching running can be carried out easily, and a stable stopping operation can be guaranteed by preventing an error starting.

Abstract: PURPOSE:To easily permit adjustment of the sensitivity current even in an assembled state and to allow electromagnetic devices with different sensitivity currents to be composed of the same parts by a construction wherein the resilient force of a spring acts on a movable yoke such that the free end of the movable yoke is pressed to come into contact with one of upper and lower yokes. CONSTITUTION:When current passes through a coil 13, this current produces the magnetic flux through a path comprising an upper fork 2, side yoke 4, lower yoke 3, fixed core 10, space including return spring 11 and a movable core 6, and a path comprising the upper yoke 2, depending piece 15, gap caused by adjusting screw 19, movable yoke 14, lower yoke 3, fixed core 10, space including return spring 11 and the movable core 6. The magnetic flux thus produced attracts the movable core 6 toward the fixed core 10. When the attraction force with the magnetic flux overcomes the resilient force of the return spring 11, the movable core 6 moves downwards. Also, the sensitivity current of this electromagnetic device is variable by changing the gap caused by the adjusting screw 19 to vary magnetic resistance of the path producing the magnetic flux.

Filed: 1995-04-20
Abstract: PURPOSE: To provide a structure of a light transmission body which is a light transmission body used for illumination, is formable to arbitrary shapes and allows the reduction of light loss and a process for producing the same. CONSTITUTION: This light transmission body is produced by previously providing the inside wall surfaces 3 of an upper mold 1 and a lower mold 2 with fine ruggedness and loading a hollow resin tube 4 formed by using a synthetic resin having a low refractive index to a small thickness into these metal molds, then injecting a synthetic resin 6 having the refractive index higher than the refractive index of the this tube into the resin tube 4 under pressurization.

Title: Controller for ac motor
Inventor: KAWADA KOZO
IPC: H02P27/06
Filed: 1990-04-12
Abstract: PURPOSE:To effect torque up in a short period of time with a small-sized device by a method wherein the driving current of an AC motor, connected to the AC side of an inverter, is constituted of square waves or trapezoidal waves, in which positive and negative peak current values are equal and inverted at a predetermined period. CONSTITUTION:DC current, obtained by rectifying and smoothing an AC power supply 1 by a rectifier 2 and a smoothing circuit 3, is put ON/OFF by a switch 18 and an AC motor 5 is operated by VVVF generated by driving an inverter 4. The speed of the AC motor 5 is detected by a detector 6 to input it into a speed control means 7 while a difference between the detected speed and a set speed is obtained to input it into an inverter control circuit 8 and control the inverter 4 so as to nullify the difference. The output of a position detector 10 is inputted into the ROMs 11, 14 of the inverter control circuit 8. The sinc wave pattern of the ROM 11 is multiplied by the output of the speed control means 7 by a multiplier 12 normally, however, the square wave (or trapezoidal wave) of the ROM 14 is multiplied by the output of the speed control means 7 in the multiplier 12 when torque-up in a short period of time is effected. According to this method, an effective value can be increased without increasing the peak value of the current.
