Title: Driving method for recording head of ink jet printer and driving circuit thereof
Inventor: MIZUNO TSUNEO
IPC: B41J2/015
Filed: 1981-09-30
Abstract: PURPOSE:To obtain clear printing by a method wherein the rise time of a driving voltage waveform is set to be longer than the fall time thereof and thereby the velocities of ink particles from a plurality of nozzles are adjusted to be uniform. CONSTITUTION:In the driving circuit of a recording head, a charge is given from an emitter follower Q2 to a piezoelectric element C0 via a resistor R4 and an output voltage rising at a prescribed time constant appears at an output terminal I2 in a period T2 when a switching transistor Q1 is OFF. When the transistor Q1 is turned ON, the charge of the piezoelectric element C0 is rapidly released through a diode D2 and the transistor Q1. Accordingly, a waveform having a sharp fall can be obtained, a stable drive of ink particles having a small diameter can be performed, a time constant can be varied since a resistance R4 is variable, and thus a particle velocity from each nozzle can be made equal. Moreover, no air bubbles penetrate into nozzles and thereby excellent printing is enabled, since the fall is sharp.

Abstract: PURPOSE:To obtain the light with high color rendering property at a high color temperature by making the line connecting the bulb seal side end of the filament of a halogen lamp and the outer edge of an effective reflection section on the seal end side of a reflecting mirror 60 deg. or above against an optical axis, or providing a film absorbing or reflecting the visible light on the bulb top section, and making the line connecting the film periphery and the side end of the filament top section 60 deg. or above against the bulb axis. CONSTITUTION:When a halogen lamp 1 is fitted to the preset position of a reflecting mirror 10, the line connecting the bulb seal side end section of the filament 5 of the lamp 1 and the outer edge of the back opening section 13 of the reflecting mirror 10, i.e., the back side outer edge of the effective reflection section, is set to 60 deg. or above against the optical axis O2 (i.e., bulb axis O1). When the lamp 1 is lighted, the filament 5 emits light, light enters a light interference film 8, part of it is reflected, the filament 5 is re-heated by the reflected light, and the luminous efficiency is improved with little power consumption. Since the back opening 13 of the reflecting mirror 10 has a large area, the light with a low color temperature from the seal end 3 of a bulb 2 is not reflected to the front, the color temperature on the radiation face is increased, and the color irregularity is reduced.

Abstract: PURPOSE:To finely pulverize quality-deteriorated residual fuel oil without using an emulsifier, by mixing quality-deteriorated residual fuel oil such as molten plastic and high temp. water in an atomizing chip and bumping overheated water droplets under reduced pressure accompanied by the injection from an atomizer. CONSTITUTION:Preheated quality-deteriorated fuel oil 1 and high temp. water 4 are made to coaxially flow through a burner gun and the injection pressure Pw of water is made higher than the injection pressure Pf of fuel oil to blow high temp. and high pressure water into the fuel oil in an atomizing chip 3 to prepare a water in oil type emulsion. Water is heated to saturation temp. or more corresponding to atmospheric pressure after injection and generates abrupt bumping under reduced pressure generated during the passage through a jet orifice 7 and springs out circumferential oil to form mist. The heating temp. of water is set to one reducing the viscosity of the fuel oil to 1,000 poise or less and the upper limit temp. thereof is set to the saturation temp. of water corresponding to the injection pressure of the fuel oil. By this method, because good spraying is obtained, the concn. of soot can be markedly reduced without increasing NOX or SOX and black smoke preventing effect at the time of the starting of a boiler is also attained.

Abstract: PURPOSE:To reduce the testing process and time by respectively providing joining sections to testers to the boxes of a high-, normal-, and low-constant temperature ovens so that the high-, normal-, and low-temperature tests of an IC can be carried out by one process. CONSTITUTION:An IC to be tested is loaded from a loader section 3 and mounted on an IC socket 2a on a rotary board 1.

The socket 2a is moved into the box 6a of a high-temperature oven 6a through a position 2c and a high-temperature test is carried out by bringing the socket 2a into contact with the test head 7a of a tester at a position 2d. The tested IC is turned to a position 2d where the IC is rejected by means of an unloader section 4a when the IC is not accepted. When the IC is accepted, the IC is brought to a position 2f in the box 6b of the high-temperature oven of the next process for the next test.

Title: Web thickness detecting device
Inventor: ISHIKAWA JIYUNICHI
IPC: G01B21/08
Filed: 1981-09-30
Abstract: PURPOSE:To perform highly accurate measurement, which well follows the change in the apparent thickness in the direction of the diameter, by adding an exponential mean circuit to a conventional arithmetic mean circuit for web thickness. CONSTITUTION:A pulse generator PG1 detects the number of rotation of an unwinding roll 1, and a PG2 detects the amount of passage of the web 4. The web thickness is computed by a well known computing circuit 11 for every N turns of the unwinding roll. In the meantime, since the apparent thickness becomes uneven in the direction of the diameter during the pattern control of the winding tension and the control of the winding firmness, the mean thickness for the entire range cannot be simply obtained. Therefore the exponential mean value TK at the Kth time is obtained by the expression TK=alpha.-TK+betaTK-1, from the computed result -tK at the Kth time, a coefficient alpha(0<2<1), and the result TK-1 at the previous time. Said value TK is the exponential mean of the arithmetic mean -tK at the Kth time. What part of the past series should be emphasized is determined by the coefficient alpha.
