Filed: 1979-07-30
Abstract: PURPOSE: To perform jam handling of read originals easily, smoothly and properly by releasing the roller pressure of original feed rollers and pressure rollers according to jam detection.  
     CONSTITUTION: When the jam of an original is detected by a counter which counts the pulses synchronized to original conveying according to the presence or absence detecting output of the original and generates an output when the count value reaches predetermined value and a detector which detects the arrival of the leading end of the original at predetermined position at that time, a solenoid 11 is energized. As a result, a cam plate 10 vibratively turns and causes the pressure rollers 2A, 2B provided to a cooperatively oscillating arm to space from feed rollers 1A, 1B, thus the press-contact forces of the rollers 2A, 2B by the elastic force of a spring 8 against the rollers 1A, 1B are released. Hence, the jam original is drawn out by the easy operation; the reader is reset automatically by the detecting output for absence of the original; the reading of the next original is resumed automatically, and the jam handling of the read original is accomplished easily, smoothly and properly.

Title: Controlling device for direction of flow
Inventor: NAWA MOTOYUKI
IPC: F24F13/08
Filed: 1979-07-30
Abstract: PURPOSE:To enable a deflection with a wide angle without producing a remarkable flow resistance by a method wherein an upper stream end of a rotatable vane is positioned at a down stream of a step of an upper side wall. CONSTITUTION:An upper stream end of a rotatable vane 11 is positioned at a down stream of a step 6 of an upper side wall 5. According to this arrangement, when the vane 11 is directed downwardly from a horizontal line by an angle theta1, an upper stream C2 of the vane 11 tries to adhere to an aft wall 7 after it is separated from the step 6, however, an effect of adhering to the vane 11 caused by the stream C2 and an inducing effect due to a stream B2 are bigger than a negative pressure effect causing a rolling stream E, therefore, the stream C2 will not be adhered to the wall 7 and is deflected downwardly. Accordingly, the deflection with a wide angle may be effected without causing a remarkable flow resistance.

Title: Printing head drive controller
Inventor: KOZAI FUMIO
IPC: B41J2/32
Filed: 1986-04-25
Abstract: PURPOSE:To generate a low noise of the titled controller, by driving a DC motor by pulse energization. CONSTITUTION:If a positive pulse energization is applied to a DC motor 9 when a link pin 13 is at a position of 0 deg. in rotary angle, a drive gear 10 is rotated counterclockwise and a follower gear 11 is rotated clockwise. Thereby, the link pin 13 is moved to the position of 240 deg. in rotary angle along a guide groove 14. Following the leftward displacement of a link lever 16, a tensile coil spring 9 operates on a drive lever 5 and a printing head 3 is pressed onto a platen 2. The traveling speed of the printing head 3 is slow because of the pulse energization at an equal pulse interval and the collision noise produced when the link pin 13 collides against one end of the guide groove 14 becomes small. Further, if a negative pulse is applied to a DC motor 9 when the link pin 13 is at a position of 240 deg. in rotary angle, the gears 10 and 11 are rotated reversely. The lever 16 is displaced rightward and the printing head 3 is separated from the platen 2. The shock noise at that time when the pin 13 strikes against the guide groove 14, becomes small.

Filed: 1982-06-09
Abstract: PURPOSE:To flat stepwise difference parts generated on a layer insulation film easily and without giving bad influences on an electrode wiring layer by a method wherein the multi-layer wiring layer insulation film is irradiated with laser light. CONSTITUTION:A thermal oxide film 12 and an Al wiring layer 13 are formed on a Si semiconductor substrate 11, and SiO2 14 doped with phosphorus or boron is formed thereon by a CVD method. Next, this substrate 11 is irradiated with cabonic acid gas laser light.

Title: Liquid chromatograph
Inventor: SHIMADA MITSUO
IPC: G01N30/34
Filed: 1985-05-10
Abstract: PURPOSE:To use one set of current varying circuits regardless of increase or decrease in the number of solenoid valves, by making circuits for controlling current and time in common-use during the operation. CONSTITUTION:Transistors (Tr) Q1-Q8 of a main switch element are connected to solenoid valves V1-V8. First, when the solenoid valve V1 is selected from among microprocessing units (MPU) 21, a temporary memory circuit 26 turns ON the Tr Q1 on a latch signal 24 from an address decoder 23. On the other hand, the signal 24 enters a one-shot multivibrator M to turn ON Tr Q for a fixed time length, current flows to the solenoid valve V1, and after a given time passes, with the Tr Q turned OFF, current flows to the solenoid valve V1 through a resistance R. Then, when selecting the solenoid valve V2, the MPU 21 turns ON the Tr Q2 alone with the signal 24 while the Tr Q1 is turned OFF to close the solenoid valve V1 and current flows to the solenoid valve V2. In this manner, the signal 24 generates to short-circuit the resistance R with the Tr Q making a rated current flow to the solenoid valve each time the contents of the circuit 26 is altered. After a fixed time, only the held current continues to flow to minimize the heat generation of the solenoid valves.

Filed: 1982-06-08
Abstract: PURPOSE:To select a desired display mode within a short time through simple manipulation, by directly carrying out the change-over of a cyclically changed- over display mode to a specific mode by switch manipulation. CONSTITUTION:Every when a switch SW1 is manipulated, signals St1, St2,... successively outputted by a step counter SC1 are applied through AND gates G2, G3,... opened through an OR gate G1 and flip-flop FF to control switches S1, S2,.... By this mechanism, function blocks F1, F2,... are successively selected to cyclically change the display mode of a display device DP. On the other hand, when a switch SW2 is closed, a set state is established and the output of the flip-flop FF is reversed to close the gates G2,... while the switch S1 is controlled by the output (q) reversed to a high level of the flip-flop FF through the gate G1 to directly select a specific display mode by the block F1. By this method, the selection of a desired display mode can be carried out within a short time by simple manipulation.
