Patent JP-S62278072-A (JP)
Title: Printing position signal generator
Inventor: ARAGAKI TAKAHIKO
IPC: B41J19/18
Filed: 1986-05-26
Abstract: PURPOSE:To enable printing position signals corresponding respectively to a plurality of printing pitches to be accurately obtained through a simple circuitry, by setting a common multiple of the printing pitches to be a minimum unit of carrier moving distance and additionally providing a bidirectional counter and a read-only memory (P-ROM). CONSTITUTION:Position signals A and B are clock signals with a 90 deg. phase difference therebetween, and a carrier moving distance per one pulse of the signals is equivalent to a common multiple of a plurality of printing pitches. A bidirectional counter 5 counts up when a carrier is moved forward, counts down when the carrier is moved backward, and outputs address signals A0-A14. A P-ROM 6 is so constructed that a logical value '1' is outputted every 12 addresse as a 0-th bit output D0, and a logical value '1' is outputted every 9 addresses as a first bit output D1. When printing at a 1/120-in pitch, an output signal is generated as a printing position signal when the output D0 of the P-ROM 6 becomes '1'. When printing at a l/160-in pitch, the output signal is generated as the printing position signal when the output D1 becomes '1'. Accordingly, a plurality of printing position signals can be generated based on the same position signals A and B.

Filed: 1992-05-14
Abstract: PURPOSE:To accurately extract the moving vector of a moving object without being affected by the area-extracted result by excluding the unexact result with statistical processing based on the directional angle and size of optical flow. CONSTITUTION:The digital image of the moving object inputted to an image input part 302 is processed with an arbitrary threshold value by an area extraction part 303 and the area, where the objective moving body exists, is extracted. An optical flow extraction part 304 calculates the optical flow for the respective picture elements of the image of the moving object. A statistical processing part 305 excludes the optical flow, which is estimated as error in one area, with the statistical processing based on the directional angle and size of the optical flow. A moving vector decision part 306 averages the remaining optical flow and calculates the direction and size of the moving vector of the objective moving body are calculated. Further, the center of gravity of the start point of the optical flow is calculated, and the start point of the moving vector is calculated.

Title: Memory access controller and its method
Inventor: KATO MIHARU
IPC: G06F13/00
Filed: 1999-04-28
Abstract: PROBLEM TO BE SOLVED: To sharply reduce the frequency of memory access such as picture printing processing. SOLUTION: When a CPU 100 reads picture data from a buffer block in which any data are never written, a memory controller 12 returns preliminarily stored initial data without reading any picture data from a picture buffer 140.

Inventor: ITOU KATSUHIKO
IPC: F24C15/20
Filed: 1983-07-04
Abstract: PURPOSE:To improve the operability and safety of a cooking unit by a method wherein if the lower atmosphere temperature in the cooking unit to be mounted in an upper space such as the cooking unit is reached to the prescribed temperature, the lower atmosphere is discharged and further if the temperature is abnormally high, the discharging operation is stopped. CONSTITUTION:A gas cooking unit 2 is used, thereby the surrounding atmosphere contains gas of foodstuff and is heated to a high temperature, e.g. 70 deg.C, a change-over contact of the first thermostat switch 13 is changed over, resulting in that a discharging motor is operated so as to discharge the air around the gas cooking unit 2 out of the room. When the atmosphere temperature is reached to an abnormal hot temperature, e.g. 90 deg.C due to scorching of foodstuff during operation of the gas cooking unit 2, a second thermostat switch 14 is also changed over in its contact switch. Thereby, the discharging motor is stopped to terminate the discharging operation. Therefore, it is possible to improve an operability and safety of the unit.

Title: Fan heater
Inventor: KAWAGUCHI SEIJI
IPC: F04D29/28
Filed: 1984-06-14
Abstract: PURPOSE:To prevent blades from breaking down due to thermal expansion and at the same time enable to ensure the energizing between heat generating body and its holding member by a structure wherein the blades of a rotary fan are made of the heat generating body and at the same time fan frames are axially pushed by elastic pushers. CONSTITUTION:When the temperature of blades 2 made of heat generating body or of a heat generating body 21 arranged near the blades 2 rises and consequently the blades 2 and the heat generating body expand thermally, fan frames 3 shift in the direction of a shaft 1 against the pushing force of elastic pushers, resulting in absorbing the axial thermal expansion of the blades 2 and the heat generating body 21. Because the heat generaing body 21 is pushed to the blades 2 or to the members 3a pinchingly holding the heat generating body 21 at all times with the proper contact pressure, which is determined by the pushing force of the elastic pushers, the energizing property between the members 3a and the blades 2 or the heat generating body 21 can be held favorably.

Title: Radio wave anechoic chamber
Inventor: OKAWA HIROSHI
IPC: G01R29/10
Filed: 1989-05-18
Abstract: PURPOSE:To decelerate propagation of a radio wave and to relatively shorten a wavelength by forming a radio wave anechoic chamber of a metal material, arranging many conical radio wave absorbers inside at least one wall of a floor wall, four sidewalls and a ceiling wall, and providing a layer which covers the absorbers inside the wall and has larger permittivity than the air occupying a containing space. CONSTITUTION:Radio wave absorbers 20 are arranged on the inner faces of front, rear, left and right sidewalls 12-15, and the outer surfaces of the respective absorbers 20 are inclined. Thus, electromagnetic waves arriving at the surfaces are partly reflected and residually transmitted. The reflected wave is not reflected toward a reception antenna 19 as it is since the surfaces of the absorbers 20 are inclined, but reflected toward the faces of any wall. Thus, the primarily reflected wave does not reach the antenna 19, and the transmitted wave is converted at its electric energy into thermal energy via the absorbers 20 to be attenuated. On the other hand, since the wave is passed through a high permittivity layer 21 until it arrives at the absorber 20, its propagating speed is decelerated with the result that its wavelength is shortened.

Title: Hold-down foot lifter for sewing machine
Inventor: FUKUSHIMA MASAHIRO
IPC: D05B29/02
Filed: 1999-04-28
Abstract: PROBLEM TO BE SOLVED: To enable a hold-down foot to switch over between one location in which the hold-down foot presses a workpiece and another location in which the hold-down foot is lifted away from the workpiece, by a very simple assembly, and decrease an energy consumption consumed by an electromagnetic solenoid. SOLUTION: This sewing machine M makes a stopper member S mounted on a lever L transfer as an electromagnetic solenoid D is driven, thereafter a hold-down foot 3 can be lifted away from a workpiece. Even after the electromagnetic solenoid D is undriven, a holding member H keeps the stopper member S. Thereby, the hold-down foot 3 is kept away from the workpiece. When the electromagnetic solenoid D is driven again while the holding member H keeps the stopper member S, the state of the hold-down foot 3 is switched from keeping away from the workpiece to holding the workpiece down.
