Title: Ink jet printing head
Inventor: ISOZAKI JUN
IPC: B41J2/065
Filed: 1989-02-10
Abstract: PURPOSE:To lessen attenuation of vibration and to lessen power consumption by a method wherein a vibration generation means transmitting vibration to one end of a head body having many nozzles interconnected to an ink passage, and a vibration absorbing means absorbing the vibration from the vibration generation means with the other end of the head proper are established. CONSTITUTION:Ink is fed to an ink passage 12 from an ink feed port 40, when oscillating voltage from an ultrasonic excitation circuit is applied to an electrode 22 of an vibration generating means 20, ultrasonic excitation is propagated to a head body 10 via piezo-electric elements 24, 26 and a piezo-piston 28 to excite the head body 10. A progressive wave is propagated to ink in the ink passage 12 by excitation with this head proper 10. An ink drop is generated from each small hole 17 for a nozzle, and flys to print a letter on a recording sheet. Ultrasonic vibration propagated to the head body 10 is absorbed when it reaches a vibration absorbing means 30. Therefore, a separative length becomes almost uniform at any position between an exciter end and an absorber end, and generation of the ink drop is uniformized.

Title: Powdered paint and method for powder coating
Inventor: KAWAMOTO NORIO
IPC: C09D5/03
Filed: 1983-02-23
Abstract: PURPOSE:To provide a powdered thermosetting resin paint having a specified particle size and suitable for use in coating the inner surface of a tubular member, consisting of an epoxy resin and a phenolic or dicyandiamide hardener. CONSTITUTION:A powdered paint consists of an epoxy resin having an epoxy equivalent of 600-950 and a phenolic or dicyandiamide hardener, has an average particle size of 80-150mum and contains fine particles having a particle size of 50mum or below in a quantity of not more than 10% based on the total quantity of the particles. When the average particle size of the powdered paint is smaller than 80mum, or the content of the fine particle having a particle size of 50mum or below exceeds 10%, the flow characteristics of the paint in a high-temperature atmosphere are poor so that when the paint is applied by rotatinal coating, the powdered paint accumulates at that position of a tubular member where the paint is fed, the paint can not be smoothly moved by the rotation of the member and hence the unevenness in coating is formed. When the average particle size exceeds 150mum, the surface smoothness of the resulting coating film is poor and the appearance of the film is inferior.

Title: Drift correction method
Inventor: ONO SHIGEKI
IPC: G01N21/27
Filed: 1986-02-14
Abstract: PURPOSE:To enable the lowering of the rate of influence of contamination of a flow cell on an analysis value, by a method wherein a reagent blank is measured at specified interval of frequency, and the resulting measured value is subtracted from the measured value of the subsequent experimental object for correction. CONSTITUTION:When a biochemical analysis is carried out by nephelometry, a reagent blank is measured at a time interval after the measurement of a specified number of specimens is made, so to speak, after a flow cell begins to contaminate. Then, the measured value of the reagent blank is subtracted from the measured value of the subsequent specimen reactant for correction. So, the correction of the measured value is accomplished before the contamination of the flow cell affects the analysis value to eliminate the effect of the contamination of the flow cell on the analysis value. Thus, a highly reliable analysis value can be obtained with a higher analysis accuracy.

Filed: 1988-02-15
Abstract: PURPOSE:To reduce motive power and working time without executing the forming of a small diameter part by taking the part on which no tooth profile of a cup shaped preform is formed as a small diameter part, forming it in the outer face shape connecting it and the cylindrical part of larger diameter than this small diameter part by taper and drawing the outer peripheral face thereof by a fixed diameter die. CONSTITUTION:A preform 1 is fitted with its opening downward to an inner punch 10 inside a die 13 to move down an outer punch 12. The small diameter part 5 of the preform 1 is passed through without receiving any drawing by an orifice 16 because of its having the outer diameter about equal to but a bit smaller than the inner diameter of the orifice 16 of the die 13 and no tooth profile is formed on the inner face. When a taper part 4 is then brought into contact with the orifice 16, drawing is started and the forming of the tooth profile is performed on the inner peripheral face. Consequently, the tooth profile is made on the necessary part only.

IPC: G01R31/28
Filed: 1991-02-26
Abstract: PURPOSE: To obtain an accurate and high functional transmission line length- measuring apparatus. CONSTITUTION: Phase difference detectors 1, 2 compare the edge (a) of a traveling wave and the edge (b) of a reflected wave with a reference pulse RP at timing, and a phase difference detector 3 detects the phase polarities of the edges (a), (b). A phase difference signal extractor 4 extracts the discordant state between the rise edges of two phase difference information signals.

A rib forming cavity part 6a is formed in the inmost recess end of the rib forming mold part 3a and an insertion hole forming mold part 3b is formed near its right end. A tubular part forming cavity 6b, which communicates with the rib forming cavity part 6a, is formed at the outer periphery of the part 3b. Under the condition just mentioned above, only skin material flows in the neighborhood of the mounting hole forming mold part 2a and at the same time flows abundantly in the neighborhood of the rib forming mold part 3a. As a result, the strength and rigidity near a mounting hole 6a can be enhanced.
