Title: Magnetic field orientation extrusion molding
Inventor: SAKATA YOSHIO
IPC: H01F41/02
Filed: 1986-05-21
Abstract: PURPOSE:To stably manufacture a resin permanent magnet having large maximum energy product by contacting a blocklike permanent magnet and/or blocklike soft magnetic unit with a molded item while the molded item extruded from a die having a magnetic field is solidified by cooling to effectively suppress an antimagnetic field. CONSTITUTION:A blocklike permanent magnet and/or a soft magnetic unit is disposed on the outer surface of a caterpillar type supporting base material 5 held by two rollers 6, 6', and the permanent magnet and/or magnetically soft unit 7 rotates at a predetermined speed. These magnet and the unit 7 are contacted with a molded item 3 extruded from a die 2, and preferably rotated by the rolls 6, 6'. The item 3 extruded from the die 2 is naturally cooled while contacting with the magnet, the unit 7, solidified by cooling to a high viscosity so that the orientation of magnetic powder in the item is not disordered, and then separated from the magnet, the unit 7. Thus, a resin permanent magnet which performs a predetermined magnetic action is obtained.

Title: Extra-high frequency transistor amplifying unit
Inventor: TAKAYAMA YOUICHIROU
IPC: H03F1/32
Filed: 1979-09-11
Abstract: PURPOSE:To simplify constitution and make a unit small-size, by incorporating a variable impedance element into the matching circuit of the transistor and by controlling the impedance matching circuit to compensate the nonlinear property of the transistor. CONSTITUTION:The microwave signal which was subjected to amplitude modulation is input to input terminal 7 of the amplifier, and a part of this signal is taken out by directional coupler 8 and is subjected to envelope detection amplification by detecting circuit 9. Most of the microwave signal is sent to FET1 through capacitor 11 for DC cut, varactor diode 6, and impedance matching circuit 2. Further, the detected and amplified signal is superposed to DC backward bias voltage VB and is applied to varactor diode 6. Then, varactor diode 6 is controlled by amplitude change of microwave input power, and only the gain is lowered in a small signal level, and the gain in the high output level is held, so that linearity of the whole can be improved.

Title: Input signal detection circuit
Inventor: KAGOYA TAKAMI
IPC: H03K5/08
Filed: 1983-06-28
Abstract: PURPOSE:To reduce the cost with a simplified circuitry by providing a filter circuit and a voltage dividing circuit and iputting a higher output level within a mean and a partial voltage values thereof into a comparator to be compared with the set value. CONSTITUTION:An input signal S1 is inputted into a comparator 2a through a filter circuit 9a and at the same time, after a voltage division with voltage dividing resistances 10 and 11, the signal is inputted into the comparator 2a through a diode 12. The division ratio of a division circuit is so set at a specified value that the ratio of the instantaneous value to the set value 3 is equal to that of the partial voltage value V2 to the set value 4a. In this manner, a higher signal among the mean V1 with the filter circuit 9a and the partial voltage value V2 with the voltage dividing circuit is inputted into the comparator 2a as comparison values V3 to be compared with the set value 4a. When the values V1 and V2 are less than the set value 4a, the output signal S3 of the comparator 2a becomes H or when they are larger than the value 4a, S3 becomes L. This enables the detection with only one comparator to simplify the circuitry thereby reducing the cost.

Title: Manufacture of thermal head
Inventor: SAGAWA SHIMIZU
IPC: H05K1/16
Filed: 1995-04-19
Abstract: PURPOSE: To make the reflectivity of a glazed layer equivalent to that of individual electrodes by lowering the surface roughness of an insulating substrate underlying a photoresist or of the one having higher reflectivity against the light used for exposing a photoresist of the metal films formed on the insulating substrate. CONSTITUTION: A glazed layer 2 is formed on an insulating substrate 1 and baked. The surface roughness of an area 10 on the surface of the glazed layer 2 having high reflectivity is lowered by roughening the surface of the area 10 by lapping. The reflectivity of the area 10 can be lowered to 40% by increasing the surface lapping amount of the layer 2. The reflectivity of the metallic films of an individual electrode 3 and common electrode 4, on the other hand, is about 50% when the film is composed of one metallo-gold film and about 10% when the film is composed of three metallo-gold films. Although the reflectivity drops as the number of metallo-films increases, the reflectivity does not drop much and falls within the range of 10-50% even when the number of metallo-gold films increases from three.  The reflectivity of the surface of the glazed layer 2 can be made equivalent to that of the electrodes 3 and 4 by changing the surface lapping amount of the the layer 2.

Abstract: PURPOSE:To eliminate the clogging of filter media and cake with a simple operation and to prevent the trouble and danger owing to abnormal vibration, by providing a skimming pipe which can control the starting time and speed of filtration and a washing liquid pipe which can be backwashed. CONSTITUTION:The position of the forward end port of a skimming pipe 9 is pulled up to the bore side from the height of a partition wall 6 by a control cylinder 10 prior to the supply of raw liquid with a supply pipe 12 for raw liquid. When the raw liquid is supplied thereafter, the filtrate is not skimmed and therefore the filtration is not accomplished quickly.

On the other hand, when a filter cloth and cake are clogged, the pipe 9 is pulled up and the valve 13 of a backwashing pipe 13 is opened to feed washing liquid into the chamber 7 through the opening part thereof. The washing liquid is conducted through a communication port 8 into a filtrate chamber 3, whereby the backwashing operation is accomplished.

Abstract: PURPOSE:To improve the efficiency of debug against an unexpected internal interruption by outputting automatically an internal interruption name, a message in which an internal interruption factor and its avoiding means are described, operand data of its instruction, and a related register. CONSTITUTION:In the case a generated internal interruption (n) is an unexpected internal interruption, an internal interruption discriminating means 13 delivers a control to a debug information monitor 4.

Next, an executing instruction operand editing means 41 is started, and moreover, an output register editing means 42 is started. In such a way, since an internal interruption or not cannot be discriminated directly, such a defect as the debug efficiency is bad can be eliminated.

Filed: 1989-05-10
Abstract: PURPOSE:To control the speed change state at the time of shifting from up-slope running to down-slope running requiring brake operation to be appropriate by holding the specified speed change ratio while the action of a brake device is detected. CONSTITUTION:A control device 20 reads the vehicle speed and throttle opening detected by a speed sensor 2 and a throttle opening sensor 1, calculates the moving average of throttle opening as well as obtains acceleration from the vehicle speed at the specified time, and on the basis of these, calculates the estimated value of running resistance. This estimated value is compared with two reference values LHI, LLOW (LHI>LLOW) for a hysteresis characteristic, and when the estimated value is larger than LHI, up-slope running is judged, and a vehicle is placed in the state of OD inhibition. When the estimated value is smaller than LLOW, a signal from a brake operation detecting means 3 is detected, and when a brake device is not in action, OD inhibition is released, but when the brake device is in action, the release of OD inhibition is not performed. The speed change state at the time of shifting from up-slope running into down-slope running can be thereby made appropriate.
