IPC: G06F3/048
Filed: 1996-06-24
Abstract: PROBLEM TO BE SOLVED: To protect a display unit not to be operated from malfunctioning by setting an identification code for each display unit and setting only the identification code of a display unit to be operated among the identification codes of the respective display units. SOLUTION: Each display unit 20 has a display part 21 and a reception part 22; and (1) is set as an identification code 26 for a display unit 20-1 and (2) is set as an identification code 26 for a display unit 20-2. When an operation signal A is outputted from an input terminal 10 to the display units 20-1 and 20-2, only the display unit 20-1 whose identification code (1) is set receives the operation signal A from the input terminal 10 since (1) is set as the identification in the input terminal 10. In this case, the operation signal A from the input terminal 10 is not received by the display unit 20-2 whose identification code (2) is set and the unit is not operated.

Title: Printer, control method and gradation control method therefor
Inventor: SHIBATA RETSU
IPC: H04N1/23
Filed: 1997-06-19
Abstract: PROBLEM TO BE SOLVED: To provide a serial printer printing a high quality image by suppressing a pattern appearing on a printed image. SOLUTION: An input image data is stored in an image memory 201 and sorted, according to a sorting table, into data being printed with a high density ink and a low density ink. The images are binarized through respective binarization circuits 203, 204 and delivered to heads D1, D2 jetting respective inks. The heads D1, D2 are arranged side by side while being shifted from each other by specified number of dots. Printing is performed such that the images are overlapped through continuous main scanning. Since one line of the image to be printed is recorded a plurality of times by means of different recording elements, pattern due to fluctuation of the recording elements is eliminated. Furthermore, since the image is sorted into two, gradation is decreased at the time of binarizing respective images and deterioration of the image due to granulation can be suppressed.

IPC: B41J2/175
Filed: 1998-06-11
Abstract: PROBLEM TO BE SOLVED: To provide an ink jet recording apparatus capable of efficiently discharging fine bubbles attached to the inner surface of the ink supply passage of a manifold by purge treatment.

Title: Modification of latex rubber
Inventor: YOSHII FUMIO
IPC: C08J3/28
Filed: 1984-08-02
Abstract: PURPOSE:To increase the tensile strength of a rubber greatly by an extremely simple operation, by immersing the rubber previously vulcanized by irradiation of its latex with light or an ionizing radiation in a solution of an aldehyde. CONSTITUTION:A latex of natural rubber or a synthetic rubber is mixed with CCl4 or a polyfunctional monomer and irradiated with light or an ionizing radiation to vulcanize the rubber. The vulcanized latex is formed into a natural or synthetic rubber sheet by a method such as dipping or casting. This sheet is immersed in a solution of an aldehyde (e.g., a 1-20% solution of glutaraldehyde or formaldehyde) at normal temperature and, after drying in air, it is dried in a dryer at about 70-100 deg.C. This extremely simple operation serves to greatly, increase the tensile strength of the rubber so that it is extremely advantageous as compared with kneading. This operation is not effective for a rubber vulcanized with sulfur and decreases its strength unfavorably.

Title: Pll device
Inventor: NAGAHARA YOSHIHARU
IPC: H03L7/20
Filed: 1983-09-05
Abstract: PURPOSE:To make it possible to make a device small-sized and reduce the variance of a frequency near a stable frequency by using an analog sampling circuit instead of a low-pass filter, a phase comparator, and a frequency divider in a PLL oscillator. CONSTITUTION:The analog sampling circuit (AS)13 samples the analog value of an input f2 to a data input terminal D when an input f1 to a clock input terminal C rises, and the AS13 latches data till a next sampling time and outputs it from an output terminal Q. When the input f2 is raised relatively, a sampling point is changed from a point (a) to a point (b), and therefore, the oscillation frequency of a voltage control oscillator VCO14 is lowered, and the frequency and the phase are converged to a prescribed value. Thus, the device can be made small-sized, and the variance of the frequency of the VCO is reduced according as the frequency of the VCO approaches the stable frequency.

Title: Failure detector of analog circuit
Inventor: IDE MIKIO
IPC: H02H3/05
Filed: 1983-09-06
Abstract: PURPOSE:To detect oscillation and to apply the titled detector to a control device especially requiring reliability to prevent previously the generation of a trouble by adding a digital circuit when an analog circuit is failed and oscillated. CONSTITUTION:To detect the oscillation of the analog circuit 1, the digital circuit 2 is added. A comparator 4 compares the output of an HPF3 with a fixed voltage value, and when the output is a voltage value more than the set value, outputs a pulse. A counter 5 counts up the output, and when counting up pulses more than a fixed number, outputs an output signal and an FF inputs the counted output as a set signal and outputs an output signal. Consequently, the oscillation due to the failure of the analog circuit can be detected and the generation of a trouble can be prevented previously.

Title: Method for drawing resin core
Inventor: SHIRAKAWA HIROICHI
IPC: B22C9/10
Filed: 1995-06-29
Abstract: PURPOSE: To easily draw a core resin while this core resin is in a molten state and to prevent a resin from remaining in a cast product, unlike a molten resin, by previously providing a resin core with separating parts, separating the core at these separating parts and drawing the cores at the time of drawing the core from the cast product. CONSTITUTION: The resin core 1 consisting of a thermoplastic resin having the separating parts 3 to be separated when tensile force is applied thereon is prepd. The resin core 1 is softened by heat after the casting and the tensile force is applied on the resin core 1 to separate the core at the separating parts 3 and to divide the core to plural parts. The respective parts are deformed and drawn from the corresponding holes 4 of the product. The resin core 1 is separated to the plural part and is drawn and, therefore, the taking of the core out of the product is possible. Since the resin core 1 is drawn in the half hard molten state before melting, the resin core 1 itself is capable of transmitting the pulling force and does not remain in the form of liquid in the product. The drawing of the entire part of the separated cores is thus possible.  Since the core is in the softened state, the resin core 1 is deformed and easily passable through the holes 4.
