Title: Recorder, recording head unit equipped with the same recorder, and temperature controller for the same head
Inventor: TAKADA YOSHIHIRO
IPC: B41J2/14
Filed: 1989-12-22
Abstract: PURPOSE:To adjust the whole body of a recording head to a uniform temperature by a method wherein a heat exchanging means having a first heat exchange part and a second heat exchange part, a heating means which heats the heat exchanging means, a cooling means which assists radiation of heat at the second heat exchange part, and a drive control means which controls drive of the heating and cooling means based on a detection value of a temperature detection means, are established. CONSTITUTION:When a switch of recording start is turned on, temperature of a support member 101 is detected with a temperature sensor 110. A controller 111, when its temperature is lower than an specified temperature, turns a heater 107 ON, and heats the support member 101. When the support member 101 reaches a specified means, ink is discharged from a discharge opening, and an image is formed on a material 108 to be recorded. When temperature of the support member 101 rises and detected temperature from the temperature sensor 110 is apart by allowable temperature or over from the specified temperature, the controller 111 turns a fan ON, sends wind to fins 106, and makes a recording head 112 radiate heat via a heat pipe 105. The support member 101 is kept at uniform temperature by action for equalization of temperature inside the heat pipe 105.

Title: Robot butt mastering method
Inventor: TERADA AKIHIRO
IPC: B25J19/00
Filed: 1994-12-19
Abstract: PURPOSE: To ensure the application of a servo amplifier even when the amplifier itself and a brake can not be turned off at a time by controlling the torque to set the largest torque of each servo motor at 0 in a butting action mode. CONSTITUTION: A weight part 130 is enclosed in a space part of a jig BC by attachment of jigs D and E. Under such conditions, a brake device is invalidated through a keyboard operation of a teaching control panel and the limit value of the largest torque of each shaft is changed to 0kg.m from the hitherto set value. Thus the current necessary for generation of a torque is not supplied to the servo motor of each shaft from a servo amplifier. As a result, a robot arm is not restricted by the motor of each shaft nor the brake device. In other words, the robot arm can freely drop. The part 130 can slightly move in the space part of the jig BC and therefore a collision action is attained so that an accurate mastering attitude is secured for a robot.

Inventor: NAKAO HIRONOBU
IPC: H01L21/8247
Filed: 1992-12-15
Abstract: PURPOSE:To provide a semiconductor device with which a read-out operation can be conducted accurately. CONSTITUTION:When a write operation is conducted, high voltage is applied to a source 2, and a channel 8 is formed by electrons jumped out to a drain 4 from the source 2. When low voltage is applied to a selection gate 20, an electric field is concentrated between a selection gate 14 and a substrate 1, a part of electrons are turned to hot electrons, and it is attracted toward a control gate 14 where high voltage is applied. The attracted hot electrons are trapped to the side of the source 2 of a nitrogen film 10, and information is written. When a read operation is conducted, a depletion layer 100 is spread in the vicinity of a drain 4 by the application of high voltage, but does not reach the point where information is written. Accordingly, whether electrons are trapped (information is written) by the nitrogen film 10 can be detected accurately.

IPC: G01N21/35
Filed: 1989-12-22
Abstract: PURPOSE: To reduce the thickness of a plate by correcting the lowness of the index of double refraction of a required material by coupling a birefringent plate and an isotropic plate on a single optical axis. CONSTITUTION: An interferometer system is incorporated with a light source 1, a lens 2, a gas cell 3, an interference filter 4 which separates an infrared band, a polarizer 5, a modulator 6, a birefringent plate 7, an isotropic plate 8, an analyzer 9, a focusing lens 10, and a detector 11. The plate 8 can produce two transmitting beams of light from one incident beam of light, with one beam being produced directly and the other beam being produced after internal reflection one both surfaces of the plate. The coupling of the plates 7 and 8 with each other causes the splitting of the incident beam into the number of beams of light on the single birefringent plate 7 and, as a result, an optical path difference which is higher than that obtained on the plate 7 can be obtained in the output. Therefore, the required thickness of the plate 7 can be reduced.
