Title: Service interruption processing system of device using absolute position feedback system
Inventor: TORII NOBUTOSHI
IPC: G06F12/16
Filed: 1983-04-19
Abstract: PURPOSE:To restart the working that is performed before the generation of service interruption when power supply is restarted by deciding whether the discontinuation of power supply is due to the break of a switch or service interruption and therefore saves the contents of a register which stores the relevant data in a service interruption mode while the DC voltage of a device is kept at a workable power supply voltage level. CONSTITUTION:When the voltage of a DC power supply reaches an intermedium level M before a switch OFF signal is supplied from a power supply unit 11, service interruption is decided and an interruption flag equal to 1 is set to a bubble memory 14 through a control part 15. Then the data required for a working program of a device to be controlled which is stored in a data register 16 is stored to the memory 14 via the part 15 and then saved. When the power supply is restarted, it is decided whether the stored service interruption flag is ''1'' or not. If the flag is not ''1'', it is judged that the service interruption is due to the break of a power supply switch. Thus the power supply is turned on again. If the service interruption flag is ''1'', it is judged whether thesevice interruption processing end flag that is stored next is ''1'' or not. If the end flag is not ''1'', an alarm is given to the operator. If the end flag is ''1'', it is judged that the device can be energized. Then the working step is reset.

Title: Manufacture of plasma display panel
Inventor: YAMADA HIROE
IPC: H01J9/02
Filed: 1997-03-21
Abstract: PROBLEM TO BE SOLVED: To facilitate bulkhead forming with thin line width and provide a high-precision plasma display by setting a ratio of a line width L1 of a photo mask within a specific range with respect to a line width L2 of a bulkhead pattern before burning when the bulkhead of a plasma display panel is manufactured. SOLUTION: After applying a photosensitive glass paste containing a light reactive organic component and a glass powder onto a glass substrate, this display is manufactured through each of exposure, developing, and burning processes using a photo mask. If a line width of a bulkhead is thinned for high precision, thickening of patterns due to light scattering cannot be ignored. To solve this problem, a line width L1 of the photo mask meets an equation: L2/L1=1.1 to 5 with respect to a line width L2 of bulkhead patterns after developing and before burning, thereby making it possible to manufacture the bulkhead for a plasma display panel of its desired line width. Hereby L2 denotes a half value width with respect to a height of the bulkhead.

Abstract: PROBLEM TO BE SOLVED: To heat the air sucked in a diesel engine by a novel method. SOLUTION: An air intake valve 11 to connect/disconnect a combustion chamber 6 to/from an air intake port 8 is arranged in an engine 1, and the opening/closing timing of the air intake valve 11 is adjusted by a valve driving mechanism 20.

The air intake characteristic by the air intake valve 11 is delayed to generate the vacuum pressure in the combustion chamber 6 as a piston 4 is lowered. The energy (the pump loss) in generating the vacuum pressure is transferred to the fresh air as the heat energy.  As a result, the temperature of the in-cylinder gas in the compression stroke following the intake stroke rises, the ignition property of the fuel is improved, and the combustion condition is also improved.

When the top surface of the document 12 is read by the top-surface read part 20 and reverse-surface read part 21, the scanning lines of the top-surface read part 20 and reverse-surface read part 21 have deviation and the image signal outputted from the reverse-surface read part 21 is delayed, but the image data of the precedent top-surface read part 20 are delayed by a timing adjustment part to match their positions. The document is read by using the two read parts, so the time is shortened and the modes are diversified.

Title: Efficient combustion method for pitch water slurry
Inventor: MATSUO ITARU
IPC: F23D99/00
Filed: 1986-03-27
Abstract: PURPOSE:To prevent a non-stable condition of flame caused by a delay in ignition by a method wherein a part of combustion air fed into a combustion chamber from a circumference of a burner is fed into as an annular circulation flow, the remaining flow is fed as an annular straight flow flowing around the circulation flow. CONSTITUTION:Pitch water slurry is injected or atomized into a combustion chamber A from an extremely end of a burner 1 together with injection mixing medium and in turn combustion air passes through a circulation unit 3 from an air chamber 5 and is injected into the combustion chamber A, and then ignited there. In this case, a part of the combustion air passes through a circulation vane part 10 with a twisting angle of 35-45 deg. of a circulation unit 3 and is injected into the combustion chamber A as an annular circulation flow, which the remaining combustion air passes through a straight forwarding annular clearance 11 of the circulation unit 3 and then is injected into the combustion chamber A as an annular straight flow. A high stable flame is formed by the combustion of pitch water slurry within the combustion chamber A. A ratio between the annular circulation flow of combustion air and the annular straight flow is in a range of 6:4-8:2. In order to stabilize the flame within the combustion chamber A, a part of all air volume is supplied to a flame position within the combustion chamber independent from that being fed from the circumference of the burner.
