Title: Ink jet recorder
Inventor: MORIGUCHI HARUHIKO
IPC: B41J2/05
Filed: 1990-02-02
Abstract: PURPOSE:To make a recorded image uniform and obtain a high-quality image at high speed by controlling variably the waveform of an electric energy applied to a thermal resistor according to the ink discharge properties of each discharge aperture. CONSTITUTION:A recording signal is transferred to a shift register. If the recording signal is such as requiring an ink discharge, the shift register 1 causes pulse generators 2, 3, 4 to generate a trigger signal individually and subsequently, a pulse of specific width is generated in thermal resistors 8, 9, 10 of discharge apertures A, B, C beforehand so that the ink discharge amount becomes equal to a specified value in accordance with the discharge properties. Then switches 5, 6, 7 are turned ON. Thus pulses of different set widths run through the thermal resistors 8, 9, 10 at specified voltage and a fixed amount of ink droplets are discharged and splashed from the discharge apertures A, B, C. Therefore, a uniform image can always be obtained on the medium for recording.

Title: Stirling freezer
Inventor: OKUDAIRA TOSHIAKI
IPC: F25B9/14
Filed: 1992-02-10
Abstract: PURPOSE:To maintain maximum freezing efficiency by keeping a phase difference between a compressor and a displacer both constituting a freezer with respect to a pressure loss change caused by the long term operation of a free piston type stirling freezer. CONSTITUTION:A compressor 1 provides a pressure change to operation gas 7 by reciprocating motion of a piston 2. A driver 8 sets the number of repetition of the reciprocating motion of the piston 2, i.e., driving frequency. The operation gas 1 to which the pressure change is imparted forces a displacer 4 of a cold head 3 to be rendered to a reciprocation motion. The displacer 4 includes an orifice 6 mounted thereon and is fixed to a casing of the cold head 3 through a spring 5. A temperature sensor 10 obtains cooling temperature information from the cold head 3 and supplies it to a driving frequency control part 11, and the driving frequency control part 11 keeps a phase difference between the displacer 4 and the piston 2 at an optimum value correspondingly to the cooling temperature information of the driving frequency by a driver 8.

Filed: 1982-02-16
Abstract: PURPOSE:To eliminate the recompensation after an operation and therefore to shorten the arithmetic processing time, by always obtaining a binary coded decimal in the form of absolute value through the same cycle operation regardless of the fact that the decimal operation is substantially an addition or a subtraction. CONSTITUTION:An addition or subtraction is carried out between two binary coded decimals to obtain an arithmetic result of binary coded decimal. In this system, the arithmetic result output of an adder 4 is selected in case an output having no compensation is delivered from the 1st deciding circuit 6 that decides whether a complement of arithmetic result is obtained or not. Then the output  of the 2nd deciding circuit 5 feeds the arithmetic result output as it is to the digit having a carry in an arithmetic mode. The arithmetic result output is added with the compensating value before it is fed to the digit having no carry.  When an output having compensation is delivered from the circuit 6, the complement output of (1) is selected for the arithmetic result of the adder 4. This complement of (1) is added with the compensating value before it is delivered to the digit having a carry. While the complement of (1) is delivered as it is to the digit having no carry.
