Title: Microwave integrated circuit
Inventor: KUNUGI MASARU
IPC: H01P5/02
Filed: 1989-02-15
Abstract: PURPOSE:To reduce the reflection in a connected part by using a converter with a throughhole exposed gradually to a slope face formed thereto so as to connect a case of a microwave integrated circuit and a ground conductor of a transmission line. CONSTITUTION:A lead terminal 22 led from a case 21 of a microwave integrated circuit 2 passes through the center of a throughhole 32 of a converter 3 and connects to a line pattern of a microstrip line 1. Since the exposed state of the throughhole 32 is varied continuously with a slope 31, the distribution state of the electric field is varied gradually in the part of the converter 3 from a parallel state directed downward to a radiation shape. Thus, the transmission mode of a radio wave from the microstrip line 1 is converted from the microstrip mode into the coaxial mode gradually and the radio wave is sent to the microwave integrated circuit 2. Thus, the presence of reflection at the connection part is reduced.

Title: Constant-current chopper circuit
Inventor: NAKAYA YOSHIMASA
IPC: H02P8/12
Filed: 1994-03-03
Abstract: PURPOSE:To operate a stepping motor with a high accuracy and a high resolution by making the relation between the number of steps and a motor turning angle linear. CONSTITUTION:A detected voltage Via (a detected current value) and a command voltage Vsa (a target current value) are applied to a constant current chopper circuit 2a. Since the output voltage Voa is at a low level while the Via does not reach the Vth, the motor current increases through a negative-logic motor driver 3a. At that time, the Vth is equal to the Vsa because a transistor TR becomes off. When the Via rises to the Vth due to the increase of the motor current, the motor current decreases because the Voa reverses to a high level and the Vth decreases to Vsa.R2/(R1+R2) since the TR becomes on. When the Via drops to the Vth due to the decrease of the motor current, the motor current increases again since the Voa comes back to the low level and the Vth rises to the Vsa since the TR becomes off. By this, a hysteresis DELTAVth of the Vth is Vsa.R1/(R1+R2).

IPC: G06T7/00
Filed: 1992-01-27
Abstract: PURPOSE:To shorten processing time by setting automatically a convex polygon to an image processor as a retrieving area for detection of a subject. CONSTITUTION:The detecting points P1-Pn (set disorderly) are detected in sequence and counterclockwise around a reference point G set inside the groups P1-Pn of detecting points which are photographed in a sampling step. Then all detecting points forming the apexes projecting toward the inside of the groups of detecting points are deleted, and only the detecting points that serve as the apexes projecting toward the inside of the groups of detecting points are stored as the elements of a convex polygon connecting the outside detecting points together. Therefore the convex polygon formed by connecting counterclockwise the detecting points finally remained in a file in the file writing order has the least area including all detecting points stored by sampling and is identical with a convex polygon that is formed by connecting the outside detecting points together and includes all detecting points that are detected by sampling and stored. Therefore it is just required to detect a subject wirhin a limited range of a set retrieving window.

Title: Voltage drop detection circuit
Inventor: ASOU MAKOTO
IPC: H02H3/24
Filed: 1982-03-06
Abstract: PURPOSE:To enable the discrimination of the state of the source voltage, whether it is normal, low or OFF by determining the voltage of the voltage source based on a Zener voltage of a Zener diode and a voltage between the base and the emitter of a transistor. CONSTITUTION:The voltage V of a voltage source when a transistor 21 is ON or OFF is determined by a Zener voltage of a Zener diode 23 connected between the base of the transistor 21 and the voltage source and a voltage between the base and emitter of the transistor 21. In this arrangement, a green light emitting diode is used for a signal load A24 and a red light emitting diode for a signal load B25. If so, when the voltage V of the voltage source is normal, the green light emitting diode lights while the red light emitting diode goes out. When the voltage V of the voltage source falls below the desired level, the red light emitting diode lights while the green light emitting diode goes out. When the power source is OFF or the voltage V is close to 0, both of the LEDs extinguish.

Title: Ink jet recording device
Inventor: NAKAMURA MASAHIRO
IPC: B41J2/015
Filed: 1990-02-15
Abstract: PURPOSE:To avoid occurrence of tensile stress exceeding the allowable stress in a piezoelectric material and prevent the destruction of a vibrator due to temperature changes by a method wherein the member larger in linear expansion coefficient than the piezoelectric materials composing the vibrator is used in vibrator-fixing members and the vibrator and the vibrator-fixing members are assembled together at a tempera ture higher than a predetermined temperature at which an ink is melted and liquified. CONSTITUTION:When the temperature of an ink jet head is changed to liquefy or solidify an ink, most of the part are expanded or contracted. Concerning a vibrator 20 and vibrator-fixing members 30, however, these members are always contracted as compared to their jointing time, because the temperature changes are made at a temperature lower than that at their jointing time. Moreover, since a member larger in linear expansion coefficient than a piezoelectric material 31 is used in the vibrator- fixing members 30, the members 30 with the vibrator 20 interposed there-between is more contractible then the piezoelectric material 31. For this reason, a compressive force is continuously exerted on the piezoelectric material 31 in the direction of the arrow A from the beginning of the jointing. Therefore, the stress exceeding the allow able stress and particularly a tensile stress on the piezoelectric material 31 is avoided, whereby the destruction of the vibrator 20 due to the temperature changes is prevented.

Title: Laser oscillator
Inventor: NAKAOKA KENKICHI
IPC: H01S3/134
Filed: 1995-02-23
Abstract: PURPOSE: To provide a laser oscillator having excellent response and stable output. CONSTITUTION: An oscillator control part 5 receives a laser output command signal 23 from an NC equipment 3, converts the signal 23 to a direct voltage waveform command signal 25, and transfers it to a power supply part through an adder 7. The power supply part receives the voltage waveform command signal 25, supplies discharge power, and generates a laser light LB from an oscillation head 15. A laser light output detector 21 detects the laser light LB, and transfers a light output detection signal 27 to a comparator 19. A simulator 17 estimates response characteristics form the power supply part to the laser light output detector 21, simulates the voltage waveform command signal 25, and transfers it to the comparator 19. It obtains the deviation of the light output detection signal 27 from the signal from the simulator 17, and transfers the deviation to the adder 7. The adder 7 sets the deviation from the comparator 19 as a negative signal, adds it to the voltage waveform command signal 25, and corrects it, which is transferred to the power supply part.
