Title: Welded joint method for stainless steel tube
Inventor: ENOMOTO KUNIO
IPC: B23K9/23
Filed: 1980-11-10
Abstract: PURPOSE:To manufacture a stainless steel tube joint which can prevent a stress corrosion cracking without requiring a post treatment, by previously performing build-up welding with a anticorrosion metal on the internal circumferential surface of the edge of the coupling part of a stainless steel tube, and then by performing butt welding at the tube end. CONSTITUTION:Over the entire internal circumferential surface of stainless steel tube 1 extending from the tube end by length (l), built-up part 2 made of anticorrosion metal of thickness (q) is provided by welding. After the build-up welding, shot peening or roll work is carried out at build-up part 2 and its circumference. As a result, layer 3 given the residual stress of compression is formed on the surface. The edges of this tube 1 and tube 1A of the same structure are formed and butted for coupling at weld zone 4 of low-carbon stainless steel, thereby obtaining a tube joint. Of this tube joint, the metallurgically sensitized part generated in the formation of weld zone 4 is covered with build-up parts 2 and 2A, so that stress corrosion  cracking is prevented.

IPC: B41J2/205
Filed: 1981-10-07
Abstract: PURPOSE:To make it possible to continuously record halftone images on a long recording medium by causing ink particles to deflect in the direction substantially perpendicular to the direction of movement of a nozzle when image elements are recorded by moving the nozzle. CONSTITUTION:Halftone images are recorded on a recording medium 5 moving in the direction of Y by an ink jet recorder 8 moving in the direction of X, and at this time 1 image element is recorded by MXN dot matrix by causing ink particles to deflect in the direction substantially the same as that of movement of the recording medium. To charge ink particles, the output of a sine wave oscillator 21 is shaped into a specified pulse width by a clock signal generator 22 divided into the number of ink particles in the direction of N row by a frequency divider circuit 23 and further frequency divided into MXN by a frequency divider circuit 25, and signals corresponding to the sequence of printing  of ink particles are generated from a signal generator 26. Then, halftone components of an original image are generated by a photoelectric converter 27 as  signals having amplitude corresponding to the level of density and ink particles are charged with such signals which are compared 29 with reference level.

Abstract: PURPOSE:To judge the hook-up operation of master equipment in a house from a DC voltage by applying the DC voltage to a speech line only when the handset of the master equipment in the house is put off the hook for a communication between keeper's master equipment and the in-house master equipment. CONSTITUTION:When a keeper performs calling operation for the in-house master equipment 3, a CPU21 sends a call signal to a signal line 5 to perform a switching connection with speech lines 4A and 4B and the call time limiting timer incorporated in the CPU21 is set. The CPU31 of called in-house master equipment 3 connects a relay 32 to the speech lines 4A and 4B on the basis of its own address that said call signal contains and also generates a chime tone. When the handset of the in-house master equipment 3 is put off the hook, the DC voltage is applied to the speech lines 4A and 4B, so the CPU21 of the keeper's master equipment 2 resets the call time limiting timer on the basis of the hook-up detection output of a UD detecting circuit 23.

Abstract: PURPOSE:To keep the fluctuation of frequency caused by the variance of power voltage within a rated range and to omit the elements like a Zener diode, etc., by correcting the junction capacity of an oscillation transistor to a prescribed level despite the variance of the junction capacity. CONSTITUTION:When a capacitor C1 is connected between the base and the emitter of an npn transistor TR Q10, the pads A-D are provided to a substrate pattern to show the attaching position of the C1. Then a circuit constant is selectively connected to the positions of the pads A-D in accordance with the base-emitter junction capacity Cbe of the TR Q10. Thus the corrected capacity is secured in response to the length of the pattern formed between the TR Q10 and the capacitor C1. Then the variance of frequency can be kept within a prescribed range despite the variance of the junction capacity.

Abstract: PURPOSE:To make a fitting adjustment unnecessary and make a self-diagnoses possible by allowing a memory to store position data of both ends of a potentiometer provided for sensing the opening degree of an air mix door, in an air- conditioning apparatus with a micro-computer. CONSTITUTION:An RAM33 is allowed to store data of both sides of the opening degree of a door, that is, those in maximum cooling and maximum heating, by moving an air mix door 17 in the total stroke.

If a change of the opening degree corresponding to the full stroke change is below the prescribed value owing to looseness of a fitting screw etc. of the potentiometer 41, the cause shall be defined to be a kind of trouble, and if the error is out of the allowable range, and the full stroke data shall be defined again.

Title: Transparent conductive film forming agent, conductive base board and manufacture of this base board
Inventor: MAEDA KENJI
IPC: C09K3/16
Filed: 1997-06-17
Abstract: PROBLEM TO BE SOLVED: To form a conductive base board on which a patterning line head top part has high parallelism to the base board by using an inexpensive transparent conductive film forming agent by irradiating ultraviolet rays to the base board having an indium-tin-diketone complex film, cleaning/removing a complex of a nonirradiated part, and baking it in the next place. SOLUTION: A transparent conductive film forming agent composed of an indium-tin-diketone complex obtained by hydrolyzing an indium compound, a tin compound and a diketone compound, is imparted to a base board by adjusting viscosity when necessary. A mask is put on a part except for a patterning necessary part of the base board to which the film forming agent is imparted followed by the irradiation of the ultraviolet rays. Next, when the base board is cleaned by a solvent, the film forming agent of a masked part is washed away, and only a part receiving ultraviolet ray irradiation without being masked remains on the base board. When this base board is baked, a conductive base board 1' having a patterning line 2' on which a head top part is parallel to the base board 1' can be obtained.
