Title: Extrusion molding equipment
Inventor: TSUCHIYA SHIROU
IPC: B29C51/00
Filed: 1980-08-29
Abstract: PURPOSE: To prevent possible slackening of a sheet during conveyance by temporarily storing it with a moving frame between a extruder for continuously extruding the sheet and an intermittently working molding machine.  
     CONSTITUTION: While a molding machine 7 is under the die clamping, a moving frame 6 initially positioned as indicated by the two-dot chain line is moved to the left and an auxiliary moving frame 11 downward so that a sheet M extruded continuously from an extruder 1 is inserted between a sheet guide belt 8 and a sheet conveying device 9 for temporary storage. Then, when upper and lower dies 14 and 15 of molding machine 7 are opened, a mobile belt conveyor 20 is moved to the left to retain a molding m (n) with a clip 21. As soon as the conveyor 20 is shifted to the right, the frame 6 is moved to the right (the frame 11 is moved upward) to carry the sheet M into the molding machine 7. Thus, the operation is shifted to the subsequent molding cycle.

Title: Image reader
Inventor: ITO YASUO
IPC: H04N1/04
Filed: 1988-05-19
Abstract: PURPOSE:To suppress irregularity on an original image, to perform reading smoothly, and to perform position control with high accuracy by controlling the carrying speed of an original or the travel speed of an optical system at a time when a read stoppage signal is detected even in case of inputting the read stoppage signal from an external device. CONSTITUTION:Since the scanning length of the optical system is decided uniquely by the number of pulses driving a stepping motor by a CPU208, the CPU208 judges the completion of the reading of the original at a time when the required number of pulses is outputted to the stepping motor, and performs the turn OFF of a lamp and the inversion control of the stepping motor, and also, outputs an original reading completion signal to the external device. An original illumination unit 24 advances in a direction of an arrow C by the inversion control of the stepping motor by the CPU208, and stops at a time when arrival to an initial position is detected by a reference position sensor at the time of reading a (book mode). When no next original reading start command is inputted from the external device, the unit completes a series of operations staying at the initial position.

Filed: 1983-06-30
Abstract: PURPOSE:To obtain a signal recording medium prevented from reproducing with time shift or allowed to reduce considerably the time shift by recording signals by shifting the signals relatively from a simultaneously read position by a prescribed distance corresponding to the difference between delay time values generated in respective reproducing while considering these delay time. CONSTITUTION:A video signal to be delayed is inputted from a terminal 9 and inputted to an A/D converter 11. Usually, the A/D converter 11 samples an 8-bit signal at 3fsc sampling frequency and A/D converts the sampled signal. The fsc is a color subcarrier frequency. The output of the A/D converter 11 is inputted to a velocity converter 12 and velocity converted contents are stored in a memory 13 constituted by an RAM. After delaying the data stored in the memory 13 by 3 fields, a velocity converter 14 reads out the delayed data. A D/A converter 15 converts the read data into an analog signal and outputs the analog signal to a terminal 10 as a delayed video signal.

Abstract: PROBLEM TO BE SOLVED: To obtain a liquid container for ink jet recorder in which the ink can be supplied stably by sectioning the upper side of a communication passage as a first region contributive to move the atmosphere to the liquid containing chamber side and the lower side as a second region contributive to move a liquid to the negative pressure generating member containing chamber side. SOLUTION: When an apparatus is operated, an ink 9 is fed from an ink containing section 6 to an ink jet recording head through a gap 8 communicating an ink containing section 6 and a negative pressure generating member containing section 4 between the end B of rib and the bottom 11 of an ink cartridge and a negative pressure generating member 3. Consequently, the inner pressure of the ink containing section 6 drops and the pressure difference from the negative pressure generating member containing section 4 increases as the recording is continued but since the negative pressure generating member containing section 4 is opened to the atmosphere through an atmosphere communication hole 13, the air passes through the negative pressure generating member 3 and enters into the ink containing section 6 through the gap 8.  At that moment of time, pressure difference is eliminated between the ink containing section 6 and the negative pressure generating member containing section 4.

Abstract: PURPOSE:To suppress by-production of higher silane and improve the yield of monosilane, by reacting magnesium silicide with an ammonium salt in the presence of liquid ammonia while suppressing the water-content of the reaction system below a specific level. CONSTITUTION:Magnesium silicide is reacted with an ammonium salt (e.g. ammonium chloride) in the presence of liquid ammonia suppressing the water- content of the reaction system to <=0.5pts.wt. per 100pts.wt. of magnesium silicide.

Title: Fluorescent lamp lighting device
Inventor: KUGO MASARU
IPC: G08B21/00
Filed: 1988-05-20
Abstract: PURPOSE:To aim at improvement of reliability coupled with a reduction of power consumption by giving the alarm for a disconnection of a filament through a judgement based on the discrimination of the number of high frequency if it is the value obtained when a filament of a fluorescent lamp works normally or is the one obtained when it is disconnected. CONSTITUTION:Oscillating frequency of a high-frequency inverter circuit 1 is small when a fluorescent lamp 2 is burnt normally, whereas it becomes large in the anomalous case where a filament is disconnected. By discriminating a difference in frequency, a means of discrimination 5 judges whether the fluorescent lamp 2 is burning normally or not and outputs the signal that is an index of the discrimination to a means of annunciation 6. The means of annunciation 6 executes a burning or a putting off of a lamp or works as a display according to the input signal, in order to announce a disconnection of a filament of the fluorescent lamp 2. Thus an improvement of reliability and a reduction of superfluous power consumption are achieved at the same time.
