Title: Thermal transfer recording device
Inventor: SHIMADA KAZUMITSU
IPC: B41J2/36
Filed: 1991-08-01
Abstract: PURPOSE:To stabilize the peeling of ink, and to obtain an image having a uniform transfer state and excellent quality by unifying the electric conduction finish time of each dot in a device, in which gradation is controlled by a conduction time by using a thermal head composed of a plurality of dots. CONSTITUTION:When a thermal head 34 is driven, a clock signal from an oscillator 1 is frequency-divided into 1/N by a frequency divider 2, and transmitted over a gradation counter 3, and an output from the gradation counter 3 is input to the terminal A of a comparator 6. Addresses are counted up to 0-N-1 by an address generator 4 by the clock signal from the oscillator 1, and the data of the position of a picture element to be interest is output from a scale 5 by the address, and input to the terminal B of the comparator 6 and the input signal of the terminal A is compared. When B is equal or more to A, a signal indicating electricity conduction is output to the thermal head 34. Said operation is conducted repeatedly until the gradation counter reaches 1 and gradation signals are generated, and the terminal sections of electric conduction width are kept constant at every gradation.

Filed: 1998-06-25
Abstract: PROBLEM TO BE SOLVED: To prevent the decrease of the emission rate of a microchip by ion pumping by providing on a cathode side, a sacrificial region of an electron- emitting microchip which is addressable independently from an active region. SOLUTION: A cathode 1 is placed opposite to an anode for cathode emission, and an electron-emitting microchip 2 is deposited on a cathode conductor 7 formed in plural line. A main grid 3 is made by an electroconductive layer formed in a line perpendicular to a cathode conductor row. The cathode 1 contains a sacrificial microchip 2' in a sacrificial region, individually addressable from a line 7 by using an additional electrode 7'. This region is engaged with a sub-grid 3' individually addressable from the line of the main grid 3. In order to improve the degree of vacuum in a space 11 between electrodes, the sacrificial microchip 2' is addressed when a screen is completed, and ion pumping is carried out. It is preferable to repeat this process, even after using the screen to regenerate the vacuum for next usage.

Title: Pipe bending method
Inventor: HAMANAKA SUKEAKI
IPC: B21D9/01
Filed: 1987-08-04
Abstract: PURPOSE:To improve bending quality and working environment by inserting a plate coil spring into a bending position on a straight pipe and performing bonding. CONSTITUTION:The plate coil spring 12 is inserted into the bending site on the straight pipe 11. The spring plate width (w) is made larger than the plate thickness (t) and the following conditions are desired to be set: d1MIN<=d2MAX (d1; inner diameter of blank pipe, d2; outer diameter of spring) and P1=t (P1; spring pitch at the time of largest compression). When the pipe 11 is bent under these conditions, in an inner circumferential position giving the maximum bending, each coil of the spring 12 is bonded to each other and creases are prevented from occurring. The flattening of the bent pipe 11 is prevented by strengthening of rigidity of the spring strip. The bending quality of the pipe 11 is improved, accordingly, and, in addition, since the operation to fill the sand in the pipe is eliminated, dust is prevented from being scattered and the working environment is improved.

Title: Electronic watthour meter
Inventor: NAKADA SEIICHI
IPC: G01R22/00
Filed: 1991-08-02
Abstract: PURPOSE:To reduce cost while enhancing reliability by providing a creeping circuit for comparing the count of an internal counter with a reference value upon interruption of a power pulse from an electric energy frequency converting circuit. CONSTITUTION:An anticreeping circuit comprises a microcomputor and an AND gate. The microcomputor compares the count of an internal counter with a predetermined reference value upon interruption of power pulse from an electric energy frequency converting circuit. A predetermined value is set upon rising of the internal counter which subsequently performs down counting until next rising time. If the count is higher than a reference value, a 'High level' creeping output is delivered to the AND gate and the power pulse is counted thus accumulating the electric energy. If the count is lower than the reference value, a 'Low level' creeping output is delivered to the AND gate and no power pulse is counted thus preventing the creeping.

Filed: 1989-07-27
Abstract: PURPOSE:To prevent an engine from vibrating and stalling with a miniature device by controlling the increased speed of field exciting current with the use of an integrating circuit to the making of the electric load of an alternator, with the controller of the car generator for charging a battery. CONSTITUTION:The field exciting current of the field winding 13 of an AC generator 1 for a vehicle is controlled by a control circuit 3. At the time of a constant load state, the rate of conduction of a transistor 39 is detected by an average conduction-rate detecting circuit 32, and a duty is determined by a step-down circuit 34 and the maximum signal generating circuit 35, and with an AND with the output of a voltage controlling circuit 31, the transistor 39 is ON/OFF-controlled. When a large electric load 6 is made, then battery voltage is suddenly lowered, but due to the time constant of the average conduction rate detecting circuit 32, the ON-duty of the transistor 39 is slowly increased. Accordingly, the field exciting current also ascends slowly, and so is an engine load not suddenly changed.
