Title: Lamp signal generating method, lamp signal generator, liquid crystal driving device and liquid crystal display device
Inventor: TSUCHIDA SUSUMU
IPC: G09G3/36
Filed: 1995-02-28
Abstract: PURPOSE: To eliminate unnecessary radiation by generating a lamp signal whose amplitude is changed according to a count value by performing a switch so as to increase the changed mount of the amplitude for the count value when a count-down is performed in an amplitude amount conversion process. CONSTITUTION: When the frequency of a clock count signal is made 7.5MHz, for instance, in a lamp signal generator 7, the count time for 128 clock count signals when a count-up is performed is 17μs. The time for 32 clock count signals when a count-down is performed is 4μs and the discharging time of a liquid crystal driving device 5 becomes the time which is the quarter of charging time or below. In the generator 7, the frequency of the clock signal to be supplied to an UP/DOWN count when the count-down is performed is made the same low frequency as the one at the time of up count. Therefore, the generator is inexpensively formed by a normal semiconductor process with a few processes. Unnecessary radiation is not generated and the image quality of a liquid crystal display device is made high image quality.

Title: Gun type burner
Inventor: NAKASHIMA AKIHIKO
IPC: F23D11/24
Filed: 1981-03-20
Abstract: PURPOSE:To provide a gun type burner having superior characteristics of combustion by a method wherein a primary and secondary air volume is controlled in such a manner as a balance may be adjusted between a volume of combustion and an injection by nozzle when the combustion volume is varied so as to perform a superior mixing and stabilizing the flame over a range from a low combustion volume to a high combustion volume. CONSTITUTION:As combustion is changed from its low combustion to a high combustion, the primary air is swirled and mixed over the flame holding unit 22 so as to form a negative pressure area as well as to keep the held flame, and the secondary air which is made to a swirling flow at a swirling blade 13 is throttled at the orifice part 29 by the secondary flame holding plate 28 arranged at the leading end of an outer cylinder 12, a strong or high negative pressure area is generated at the back surface of a secondary flame holding plate 28 so as to retract the unburnt gas. Since the secondary air is supplied under its eddy current for the non-combustioned gas, the mixing is promoted at the secondary flame holding plate 28, resulting in providing a stable and superior combustion ranging from a low combustion to a high combustion.

Title: Liquid level controller
Inventor: KOSAKA SHIGEO
IPC: G05D9/12
Filed: 1988-02-24
Abstract: PURPOSE:To easily change the variation range of the water tank pondage and the water retaining time by using a timer circuit which works in response to the output signal of a liquid level detecting circuit to forcibly invert said output signal after a fixed time and at the same time releases its own working before the output signal of the liquid level detecting circuit is inverted next. CONSTITUTION:A timer circuit 5 works in response to the signal of a liquid level detecting circuit 3 to forcibly invert the output signal of the circuit 3 after a fixed time and at the same time releases its own working before the output signal of the circuit 3 is inverted next. Thus it is possible to stop the drive of a pump 4 by the function of the circuit 5 after a fixed time without waiting for detection of one of high and low liquid levels even in case the pump 4 is actuated by the circuit 3 after one of both liquid levels is once detected. As a result, the pondage variance range of a water tank 1 and the water stay time can be easily controlled in accordance with the situation with no control of a liquid level detecting means 2.

Abstract: PURPOSE:To efficiently measure displacement by constituting the titled converter so that displacement transmitted from the outside is detected as receiving pressure by a semiconductor pressure sensor through a diaphragm sealed with a liquid. CONSTITUTION:Seal liquid 18, 19 are respectively equal in a volume and the volumetric change constants of bellows 13 and a seal diaphragm 15 are equal to minimize the effect of a standard state to a semiconductor pressure sensor 14 due to the expansion of the seal liquids to the change in circumferential temp. The chamber in the side of the seal diaphragm 15 and the seal liquid 19 is set to atmospheric pressure through an opening part 24 and brought to the same atmospheric pressure condition as that in the side of belows 12, 13 to be prevented from receiving the effect of the change in atmospheric pressure. A connection metal fitting 25 is fixed to a support metal fitting 10 and connected to matter 28 through a spring 27. A leaf spring 11 limits the movement of the bellows 13 only to the movement of the matter 28 to prevent the generation of an error caused by the movement of the bellows 13 to an arbitrary direction by impact and vibration.
