Title: Combustion chamber of internal-combustion engine
Inventor: SAITOU KAZUYUKI
IPC: F02B31/02
Filed: 1982-03-05
Abstract: PURPOSE:To suppress the occurrence of knocking and reduce a fuel consumption, by a method wherein depressed lengths of valve sheet rings located to ports away from and in the vicinity of an ignition plug are set to a specified relation. CONSTITUTION:An internal-combustion engine has a main suction port 11, an auxiliary suction port 12, an exhaust port, etc. The depressed length l1 of the valve sheet ring 19 of the auxiliary suction port 12 located to a squash area 8a part positioned away from an ignition plug 14 and having a large area is set to a value being longer than the depressed length l2 of a valve sheet ring 18 of the port 11 located to a position nearer to the ignition plug 14. The auxiliary suction port 12, formed in the squash area 8a where end gas is susceptible to occur, has a smaller diameter compared with that of the main suction port 11. This enables suppressing of a rise in temperature of a wall surface to a narrow range, which results in suppressing the occurrence of knocking and reducing fuel consumption.

Title: Liquid crystal display device
Inventor: NAKAZAWA YOSHIO
IPC: G02F1/1339
Filed: 1989-02-14
Abstract: PURPOSE:To obtain the liquid crystal display device with high quality and at high yield which is adjustable in the depth of liquid crystal layer after the device is assembled and has no partial coloring in the display screen by using a piezoelectric body as a means which holds or controls liquid crystal cell thickness. CONSTITUTION:The piezoelectric body 4 is used as the means which holds or controls the thickness (cell thickness) of a liquid crystal layer 3. Namely, when a voltage is applied to the piezoelectric body 4, the piezoelectric body 4 extends or contracts by electrostrictive effect to adjust the cell thickness. Further, the cell thickness is adjusted in matching the temperature characteristics of the liquid crystal cell to compensate the temperature. Consequently, the liquid crystal layer thickness can be adjusted after the liquid crystal display device is assembled and the liquid crystal display device of high quality which has no coloring, etc., in its display screen is obtained at high yield.

IPC: B21D3/04
Filed: 1981-03-12
Abstract: PURPOSE:To prevent partial wear of rolls of a central and outlet correcting rolling device by making the rotation speed of correcting rolls high when the upset part larger in diameter than the intermediate part of a tube passes, and thereby eliminating slipping of the rolls.

Abstract: PURPOSE:To discriminate a level of an input signal with a simple operation stably with high accuracy by devising the device such that a square wave test signal is outputted to a line driver from a selection circuit when a test request signal is entered from a test switch. CONSTITUTION:With a test switch 23 closed, a test request signal is outputted from an output terminal b1 of an input/output port 20 with a command from a CPU 1 and the signal is inputted to a selection terminal SEL of a multiplexer 21 as a selection signal. Thus, the multiplexer 21 outputs a square wave test signal inputted to an input terminal B1 and the square wave test signal is inputted to a line driver 3. When the line driver 3 is operated normally in this state and no fault takes place in the circuit part, the square wave signal whose voltage changes between -12V and +12V, whose period is almost one minute and whose duty factor is 50% is outputted at an output terminal of the line driver 3. Thus, it is possible to discriminate that a level of the input signal to a MODEM 6 is a prescribed level with a simple operation.
