Title: Ink jet recording device, ink jet recording head, ink jet unit, and pressure recovery method for ink jet recording device
Inventor: MORIYAMA JIRO
IPC: B41J2/19
Filed: 1993-03-10
Abstract: PURPOSE:To prevent defective discharge of ink caused by bubbles in the ink of an ink jet record head and remove the bubbles efficiently at recovery of discharge. CONSTITUTION:When a filter 1 is provided in an ink feed passage, a valve 7 is not adhered to the filter l by ink flow to be generated by ink discharge at recording, but the valve 7 is adhered to the filter 1 when the speed of the ink flow is increased in operation for recovering discharge so as to cover a part of the filter 1. Thus, a sectional area of a flow passage in the filter 1 decreases, so that a pressure difference above a predetermined quantity is generated in front and back of the filter 1. As a result, the bubbles which can not pass the filter 1 at recording can pass it at recovery of discharge.

Title: Servo motor and position detecting method therefor
Inventor: HASEGAWA YUKIHISA
IPC: G05D3/12
Filed: 1998-03-02
Abstract: PROBLEM TO BE SOLVED: To provide a servo motor equipped with a means for accurately detecting a rotating position while using the encoder signal of low resolution and a position detecting method therefor. SOLUTION: Each time an original position signal En is inputted from an encoder 3 of low resolution, a storage circuit 9 stores that time as position data. When the position data for one rotation are stored, the spline interpolation of the position data is performed at an interpolating position data generating circuit 10, and the interpolating position data of curved line approximate are generated. Corresponding to the required resolution, a precise position data generating circuit 11 extracts data from the interpolating position data and generates precise position data. A position signal generating circuit 12 always compares the value of a timer provided inside with the precise position data and at the time of coincidence, a position signal Qn is outputted. When a Z signal is inputted from the encoder 3, the timer is cleared to '0'.

Filed: 1992-03-06
Abstract: PURPOSE:To measure the CN ratio of a signal from the satellite of a satellite broadcast or the like by a simple and low-cost circuit configuration regardless of the difference of a transmission system or a scramble system. CONSTITUTION:A channel tuning converter 1 selects a channel at which the CN ratio is measured from an inputted BS-IF signal or CS-IF signal. The level of the signal of the channel is adjusted by an electronic attenuator 2, outputted through an intermediate frequency amplifier 3, and an amplitude detector 4, and displayed at a CN ratio, display meter 5. The adjustment of a signal level by the electronic attenuator 2 is operated so that the CN ratio display meter 5 can indicate the specific signal level while a satellite broadcasting wave is not received by a receiving antenna (not indicated). Afterwards, the CN ratio of the signal can be displayed at the CN ratio display meter 5 by correctly directing the antenna to the direction of the satellite broadcasting wave.

Title: Contactless igniter
Inventor: KIYOUGORA YOSHITO
IPC: F02P5/155
Filed: 1980-04-17
Abstract: PURPOSE:To obtain a wide variety of ignition timing with a low cost apparatus by varying the standard angle pulse for lead angle setting by means of angle pulse and a counter and according to a driving parameter. CONSTITUTION:Control is performed with two standard angle pulses P1 and P2, and a counter which counts crank angle sensor output. A triangular wave 3 is reset when a counter output is n=i, whereby being charged with a constant current  and the wave is set to a constant value after a P1 is generated. When a time elapsed  after generation of said P1 for a period corresponding to an operation parameter, a  waveform 4 is triggered. Accordingly, ignition timing is delayed by a crank angle  which corresponds to the period from the generation of the said P1 until said waveform 4 was triggered. By this mechanism the ignition timing can be widely varied  with a low cost apparatus.

Title: Layout design device for integrated circuit, transistor size deciding device, circuit characteristic evaluating method and transistor size deciding method
Inventor: TANAKA MASAKAZU
IPC: H01L21/822
Filed: 1998-03-03
Abstract: PROBLEM TO BE SOLVED: To more precisely optimize a transistor size in a time shorter than that of a conventional case in the layout design of an integrated circuit. SOLUTION: A diffusion sharing estimating means 11 estimates a place, where diffusion is shared in the layout of the integrated circuit, based on circuit data 31. A circuit characteristic evaluating means 12 estimates and evaluates a characteristic, namely, area, delay and power consumption in the integrated circuit by using information on the diffusion sharing place, which is designated by the diffusion sharing estimating means 11. A transistor optimizing means 13 sets the various sizes of respective transistors in the integrated circuit, gives them to the diffusion sharing estimating means 11 and the circuit characteristic evaluating means 12, and selects the optimum transistor size from transistor size candidates which have been set, based on an estimation evaluation result by the circuit characteristic evaluation means 12.  Thus, the transistor size can be decided by considering diffusion sharing, and it is not necessary that transistor decision and compacting be repeated as in a conventional case.
