Title: Method for controlling common use of task
Inventor: OTOSHI NAOYUKI
IPC: G06F9/46
Filed: 1989-06-21
Abstract: PURPOSE:To obtain a control method capable of rapid processing by means of simple constitution by providing a task with a supervisory flag to be turned on/off synchronously with a task formation/deletion request generated from a master program and supervising the flag. CONSTITUTION:When a task formation request is generated from the master program 4, an operating system 1 checks the existence of the task concerned, and when the task is not formed, forms the task and turns on a bit corresponding to the program 4 in the supervisory flag of the task synchronously with the formation of the task to set up the flag. Task deletion is similarly executed and the corresponding bit is turned off to delete the flag. Since the supervisoty flag is supervised, the task common use control method capable of executing rapid processing can be obtained by the simple constitution.

Title: Driver for thermal head
Inventor: YODA SEI
IPC: H04N1/23
Filed: 1983-08-30
Abstract: PURPOSE:To obtain a high quality image without varying in the color formation density with difference in the pattern by driving an auxiliary heat generating resistor of a thermal head according to the results of counting the number of heat generating resistors to control the color forming density. CONSTITUTION:When a pixel pattern is latched with a latch circuit 2, the discrete number of drive heat generating bodies with a counting circuit 4 simultaneously and counted up with an adder/subtractor 5. Then, the signal latched with the latch circuit 2 is outputted to a heat generating body driving circuit 3 according to the output of a timing generation circuit 10 at each driving pitch to perform a recording according to the pixel pattern. On the other hand, a down counting circuit 8 provides a signal to the subtraction input of the adder/subtractor 5 at each driving pitch to reduce the value therefrom and the results are outputted to an auxiliary heat generating resistor driving circuit 7 via a D/A converter 6 to maintain the temperature of the heat generating resistor constant by varying the power source current of the power source 11. Thus, the color formation density of a recording medium can be kept constant to obtain a high quality recording image.

Title: Band saw blade
Inventor: NAKAHARA KATSUMI
IPC: B23D61/12
Filed: 1992-06-18
Abstract: PURPOSE:To cool chips produced from the cutting point of an addendum and to guide the chips to an inner chip guiding surface by a method wherein a straight-line part having a length of 2.0mm or less from the addendum is formed on the face side of the acute angular addendum of each saw tooth. CONSTITUTION:Chips produced at the cutting point of an addendum 13 flow along a first straight-line part 15. Since the chips are apt to curl owing to generated heat but the chips are difficult to curl when the straight-line part 15 is too long, the straight-line part 15 is set to a value lower than 2.0mm. The chips are guided to a chip induction surface 17 forming a guide for curling. The chip induction surface 17 connected to the straight-line part 15 is formed in a recessed arcuate shape with a radius of 0.5-3.0mm and the inner end of the chip induction surface is protruded frontward in a cutting direction from the addendum 13 by a distance of 1/2 or less of the radius. The chips fed from the straight-line part 15 are guided in a manner to arcurately roll them in not by material quality but by a recessed arcuate surface to effectively generate a curl. This constitution causes effective production of chips most of which are curled during processing of chips.

Title: Driving method for liquid crystal display device
Inventor: OOTA MASAHIKO
IPC: G02F1/133
Filed: 1986-07-07
Abstract: PURPOSE:To prevent a flicker phenomenon and shortening the life by constituting the titled device so that the width of a selecting pulse of an address signal applied to every line is made variable by the polarity of an image signal, and an applied voltage to both ends of a liquid crystal goes to equal in case of a positive pole and a negative pole. CONSTITUTION:The pulse width of an address signal 1 is varied in accordance with the time when a data signal 2 is a positive pole and a negative pole, against a common potential 3, so that a substantial applied voltage to both ends of a liquid crystal becomes the same. As for the data signal of the positive pole against the common potential 3, a voltage shift in the beginning of write of a selecting pulse works on write advantageously, a voltage VS1 being comparatively near a data signal voltage VD is written. Also, the data signal of the negative pole against the common potential 3 works disadvantageously, on the contrary, therefore, write is not enough and a voltage VS2 being smaller than VS1 is held by a picture element. In such a way, a display failure such as a flicker, etc. is reduced, and a display state which makes a good show, and also causes no time aging deterioration extending over a long period of time can be maintained.
