IPC: B41J2/335
Filed: 1990-05-08
Abstract: PURPOSE:To improve the evenness of a ceramic base to a degree in which a stable thin film transistor circuit can be formed by making the evenness and surface properties of the ceramic base be at specified values respectively. CONSTITUTION:When, e.g., quartz is used as a body material for an evening layer, ethyl silicate is hydrolyzed by adding pure water while performing pH adjustment. By doing this, silica-containing high purity sol with a particle diame ter of not more than 3,000Angstrom is obtained. By using this high purity sol, a ceramic base, e.g., alpha-Al2O3 recrystallization base is coated by a dipping method. After the coating, the base is dried and a high temperature treatment is added to complete the process. For silica fine particles, the high temperature treatment can be performed at 750 - 1,200 deg.C. By this method, the evenness at the surface of the evening layer becomes not more than 100mum for a 300mm port, and the surface properties becomes + or -10Angstrom , and the ceramic base which has the said layer can form a stable thin film transistor circuit.

Title: Clogging preventing apparatus for veneer joining machine
Inventor: OGATA KAZUNORI
IPC: B27D1/10
Filed: 1997-04-21
Abstract: PROBLEM TO BE SOLVED: To previously wipe off veneer clogging at an inlet and outlet of a connecting unit by stopping restart of a supply conveyor at the time of continuation of a sensing state of a sense signal of a sensor for sensing passage of cutting chips from a guide plate for a preset set time or more, and operating a warning unit. SOLUTION: A guide plate G guides dropping of cutting chips, and has a sensor P disposed at an intermediate part of the plate and having a projecting or reflecting type photoelectric switch for sensing the chips. Normally, a required time from cutting to completion of connecting is, for example, 0.6 sec or more, and a time for passing the chips through te sensor P is, for example, 0.01 sec. Thus, a set time in a control circuit C for deciding a clogging state is set with the 0.001 sec as a standard. Accordingly, when the sensor P becomes the sensing state for the 0.01 or more, a signal for inhibiting the restart is transmitted from the circuit C to the motor M of the conveyor 2 to temporarily stop it, and an alarm sound is generated by an alarm unit Z to prevent occurrence of clogging.

Abstract: PROBLEM TO BE SOLVED: To improve rigidity of a coupling through reduction of the size of a coupling parent plate by a method wherein constraint press of the end part of the pipe material of a truss constituting member is effected by upper and lower molds, and a continuous flat part is integrally formed by ensuring roundness of a parent material. SOLUTION: A coupling part 10 for a chord material forms a flat part 11 and a constraint round pipe part 12. The constraint round pipe part 12 is connected to the flat part 11 forcibly formed by the upper and lower molds. During a time in which deformation transfer from the round part to the flat part is effected, a curved part 13 having a low curvature of radius is formed. The curved part 13 is formed through constraint and a shape is approximately equal to a circle. The forward end of the flat part 11 is formed in a tapered off state 14. A plurality of bolt holes 17 are formed on a line to connect together the tip of the tapered off state 14 and the center of the constraint round pipe part 12. The coupling part 10 is fixed at two parent plates 15 and 16 combined together in a cross-form state and welded by a bolt 18.  This constitution ensures roundness of a pipe material and forms a flat part. Thus, the size of the parent plate is reduced and a joint distance is reduced.

Abstract: PURPOSE:To provide a pseudo graded superlattice with a low series resistance. CONSTITUTION:An n-AlAs/n-GaAs pseudo graded superlattice 2 consists of an n-GaAs micro mesa stripe 6 and a micro inverse mesa stripe 7 and a distribution in vertical direction to a paper surface of this paper is uniform.
