Title: Ink jet recording head and ink jet recorder
Inventor: HIRAKATA SUSUMU
IPC: B41J2/055
Filed: 1999-04-21
Abstract: PROBLEM TO BE SOLVED: To provide small ink jet recording head and ink jet recorder having simple structure in which generation of crosstalk is eliminated while preventing jamming of nozzle. SOLUTION: The ink jet recording head 10 comprises a seal liquid sectioning means 24 having a communication opening 26, an ink ejection opening 12 made in the ink ejection plane 28, an ejection chamber 16 provided with an ink ejection means 14, and a section 18 for holding seal liquid 22. The communication opening 26 also serves as a behavior transmitting direction altering means 32 of seal liquid, and alters the behavior transmitting direction of the seal liquid 22 from the center of the ink ejection opening 12. According to the arrangement, behavior of the seal liquid 22 is not transmitted to the surrounding seal liquid 22 and generation of crosstalk is eliminated. Furthermore, jamming of nozzle can be prevented because the ink ejection opening 12 is sealed with the seal liquid 22.

Title: Substrate heater
Inventor: INOUE KATSURO
IPC: H01L21/324
Filed: 1999-04-21
Abstract: PROBLEM TO BE SOLVED: To avoid increase of an occupied space and cost. SOLUTION: A planar heater is composed of a main heater 1 and a sub- heater 2. The sub-heater 2 is placed in the same plane as the main heater 1, and the patterns of the sub-heater 2 are placed between the patterns of the main heater 1, so as to have their respective heating regions of a substrate overlapped each other. With this constitution, a part of the substrate which is not heated is hardly produced, so that heating which makes the temperature in the substrate surface uniform can be carried out with simple on/off operations of the sub-heater 2 by a switch 8, both in the rise state and in the steady state of the substrate temperature. Occupied space and cost can be reduced in comparison with a conventional temperature control method, wherein the temperatures of a plurality of zones are controlled.

Abstract: PURPOSE:To measure a three-dimensional surface shape with high accuracy by turning an optical element which performs shearing operation in two orthogonal direction by rotating mechanisms. CONSTITUTION:Two rotating mechanisms 70 each consisting of a cylindrical spindle holder 72 having a internal screw 71 at part of the inner peripheral surface, a spindle 74 having an external screw 73 engaging the internal screw, etc., are arranged for a total reflecting element.

IPC: B41J13/02
Filed: 1987-05-13
Abstract: PURPOSE:To enable autoloading of a medium for single form by providing a constitution where a swing arm is installed on both sides of a platen shaft, a rotational shaft with a pinch roller is mounted on said swing arm, and this pinch roller is allowed to contact the platen under pressure. CONSTITUTION:A swing arm 11 is permitted to rotate in response to the rotation of a platen 1, so that a pinch roller 10 is moved along the periphery of the platen 1. Since a medium for single form 3 is set at theta>90 deg., a part near the contact part between the platen 1 and the pinch roller 10 is opened to allow easy insertion of the tip 3a of the medium for single form 3 into the contact part. After this insertion, the pinch roller 10 moves along the peripheral surface of the platen 1 in response to the rotation of the platen 1 resulting in the setting of the medium at theta<<90 deg.. Subsequently, the medium for single form curls up to prevent even thin paper from being creased and also allow even thick paper to be fed without slipping.

Abstract: PURPOSE:To improve safety of a cell while preventing the cell from accelerating its deterioration by arranging protective thermocouples on the side of a hydrogen inlet and on the part near the air outlet side while stopping the cell when detecting a temperature above the prescribed temperature. CONSTITUTION:Several pieces of thermocouples 5 for protection are arranged in an air circulating groove 3 near the hydrogen gas inlet side in the piling direction of cell stacks in the same way as the temperature control the thermocouples 1. When at least one of said thermocouples 5 detects a temperature of about 210 deg.C, the operation of a cell is immediately stopped assuming that a hot spot S is generated thus preventing the hot spot from spreading over the other piled cells. Thereby, the damage of a cell is prevented from spreading over a wide scope while eliminating the danger of explosion of the cell.
