Title: Liquid crystal driving device
Inventor: DATE YOSHITO
IPC: G09G3/20
Filed: 1998-03-04
Abstract: PROBLEM TO BE SOLVED: To reduce a bias current in a differential, input part held at a stand-by state and the power consumption of a display system by operating only a bias current for a selected liquid crytal driving device. SOLUTION: A bias current operation control signal 101 is generated from an RS flip flop(FF) to be set up by the first latch signal 1 out of latch signals 1, 2,..., m generated from a shift control part 103 and reset by the final latch signal (m). The control signal 101 is generated from the shift control signals simultaneously with valid data and controls bias current operation so that a bias current is allowed to flow only in the input period of the valid data.  Although the operation of a bias current in a comparator is generally unstable immediately after its start, there is no trouble even when bias current operation is controlled simultaneously with the valid data in accoradance with the input timing of the vaid data, an operation clock period and the operation speed of the comparator, so that the operation of a bias power supply is started simultaneously with the input of the valid data and the bias current is stopped simultaneously with the completion of input of the valid data.

Title: Improving method for signal converter, dynamic range and output signal level fixing device
Inventor: ABETA AKIRA
IPC: H03M1/08
Filed: 1989-03-06
Abstract: PURPOSE:To obtain a high dynamic range by providing an output signal level fixing a signal level after conversion to a specific value till a signal to be converted is inputted when the signal to be converted is not inputted for a prescribed time or over. CONSTITUTION:An analog level detector 5 outputs a detection signal when an amplitude level of an analog input signal is a prescribed level or below. A controller 7 switches a changeover switch 9 to an output of a digital signal generator 8 so long as the detection signal of the analog level detector 5 is inputted continuously for a prescribed time or over and an output signal of a digital signal generator 8 is outputted from a digital output terminal 4. When an analog signal with a prescribed level or over is inputted to an analog input terminal 2, the controller 7 selects the changeover switch 9 immediately to output the output of the A/D converter 3 from the digital output terminal 4. Thus, the deterioration in the dynamic range does not take place.

Title: Exhaust pipe of burner
Inventor: KATO HARUO
IPC: F23J13/04
Filed: 1986-03-10
Abstract: PURPOSE:To prevent a fixed cylinder and a slide cylinder from slipping off during normal expanding and extracting operations by bringing the end portion of a guide groove of the fixed cylinder into contact with the projection of the slide cylinder at a maximum expanding time by the expansion and contraction of the fixed cylinder and the slide cylinder, and bringing the stopper part of the slide cylinder into contact with the opening end of the fixed cylinder at a maximum contracting time. CONSTITUTION:The connection of a fixed cylinder 4 to a slide cylinder 13 is carried out in such a manner that the slide cylinder 13 is inserted into the fixed cylinder 4 while inwardly pressing the elastic portion 16 of the slide cylinder 13 by the parts of slits 14 and 15 to narrow the same. Upon this occasion, the projection 17 of the slide cylinder 13 is required to fit into the guide groove 6 within the fixed cylinder 4. After fitting, when the slide cylinder 13 is pressed into the fixed cylinder 4, a stopper portion 21 makes contact with the peripheral edge of an opening 4A and the slide is stopped and limited, and this position is set as a maximum accommodating position. Next, when the slide cylinder 13 is pulled upward, the projection 17 moves in a guide groove 6. Then, the projection 17 makes contact with the terminal end of the guide groove 6 thereby to define the movement of the slide cylinder 13. This defined position becomes a maximum pull-out position. Thus, the fixed cylinder 4 and the slide cylinder 13 accomplish the function as elongated pipes, and are safe because they are expansible and contractible and are not easily slipped off.

Abstract: PURPOSE:To facilitate removal of parts out of order and to prevent effect of an unevenly loaded developer by driving only a developing device for a prescribed time before driving an image forming device divided into 2 components of upper and lower machine parts. CONSTITUTION:An upper machine body 1 provided with a photosensitive body 3, a developing device 4, etc. and a lower machine body 2 provided with a conveying device and a fixing device 6 are combined with a hinge 7.

Title: Technique for calculating characteristic of semiconductor element
IPC: G06F17/50
Filed: 1992-03-12
Abstract: PURPOSE:To calculate an element characteristic having a negative resistance by using an electric current as the parameter of a boundary condition given from the electrode of an element. CONSTITUTION:At the time of calculating the S-type element characteristic of a thyristor or such a characteristic as the latch-up phenomenon of an IGBT containing a negative resistance part, a voltage becomes a one-valued function when a the current is considered as a variable. Therefore, in this calculating method, a voltage value is found by changing the value of a current after designating the value as a boundary condition given from an electrode. When this calculating method is used, the characteristic of a semiconductor element can be calculated when the characteristic contains a negative resistance part or when the current generally becomes a many-valued function against the voltage, since the current is used as the parameter of the boundary condition given from the electrode of the element. In addition, since the voltage becomes a one-valued function against the current, no jump occurs in the extrapolating value used as the initial value of the calculation during the course of calculating the characteristic by sweeping the parameter and the convergence of calculation can be smoothly obtained. Therefore, the characteristic of the semiconductor element can be smoothly calculated.
