Title: Magnetic head
Inventor: IWASAKI TAKASHI
IPC: G11B33/10
Filed: 1984-10-03
Abstract: PURPOSE:To measure the extent of wear of a magnetic head chip with an easy operation without requiring special measuring tools by forming conductors on both side faces of the end part in the tape sliding face side of the magnetic head chip and measuring the electric capacity between these conductors. CONSTITUTION:A tape siding face 3c of a magnetic head chip 3 is worn because a rotary cylinder to which the magnetic head chip 3 is attached is rotated in a high speed to slide the magnetic head chip 3 on a magnetic tape. Since conductor layers 8a and 8b formed on both faces of the chip 3 are worn simultaneously, the electric capacity of the chip 3 consisting of a single crystal ferrite of a dielectric in a part held between conductor layers 8a and 8b is changed. A certain voltage is applied to conductor layers 8a and 8b on front and rear faces and the change of the voltage between them is measured to detect this change of the electric capacity. On a basis of this change of the electric capacity, the extend of wear of the chip 3 is detected in accordance with preliminarily measured data. Thus, the extent of wear of the chip is measured with the easy operation without requiring special measuring tools.

Title: Cooling device for v belt type continuously variable transmission
Inventor: YAMASHITA HIROSHI
IPC: F16H9/18
Filed: 1995-08-15
Abstract: PROBLEM TO BE SOLVED: To reduce the lubricating oil quantity necessary to lubrication by changing the distribution of the lubricating oil quantity to an input shaft side variable speed pulley and an output shaft side variable speed pulley by transmission gear ratio. SOLUTION: When a primary pulley is slided to the transmission gear ratio- small side (high side), a pulley sensor shoe 21 slides to the right side in the drawing so that the passage inlet A1 of a lubricating oil feeding passage A for the primary pulley is largely opened, and the passage inlet B1 of a lubricating oil feeding passage B for a secondary pulley is small opened. Thus, the distribution of lubricating oil is performed so that the lubricating oil quantity fed into V grooves of the primary pulley through a pipe body 18 becomes larger, and the lubricating oil quantity fed into V grooves of the secondary pulley through a pipe body 20 becomes smaller.  Further, when the primary pulley is slided to the transmission gear ratio-large side (low side), the distribution of the lubricating oil is performed so that the lubricating oil quantity fed into the V grooves of the primary pulley becomes smaller, and the lubricating oil quantity fed into the V grooves of the secondary pulley becomes larger.

Abstract: PURPOSE:To prevent the pollution by discharge of cooling water to the outside and to decrease the amt. of the cooling water to be used by circulating the cooling water for cooling an electrode by a circulating pump so as to pass the water through a hose and cooling the water by a fan. CONSTITUTION:The cooling water sucked up from a cooling water tank 15 by the circulating pump 18 flows through a supply side piping 5 in an arrow A direction to the movable electrode 3 and cools the electrode. Further, the cooling water flows through a connecting piping 6 in an arrow B direction to the stationary electrode 2 and cools the electrode. The cooling water heated up by cooling the electrodes 2, 3 flows through a discharge side piping 7 in an arrow direction C to the hose 20 where the water is cooled with air by the fan 19. The cooled water flows through a piping 22 in an arrow D direction and returns into a tank 15. Since the leakage of the cooling water to the outside is prevented in this way, the generation of the pollution is obviated. The cooling water of about the volume to replenish the decrease component by evaporation suffices.

Title: Lead forming method
Inventor: TABATA KATSUHIRO
IPC: H01L21/48
Filed: 1985-09-24
Abstract: PURPOSE:To prevent the separation of a lead from a package, by forming the lead without applying a bending stress to the main body of the package when the lead is bent at the root portion thereof. CONSTITUTION:First a lead 5 is bent perpendicularly to the direction of the width of a package 2 by putting dies 6 and 7 on the root portion of the lead, then the fore end of the lead 5 is bent inward, and further the portion bent inward is formed in a curved shape. In the process of forming the lead 5 protecting from the main body 2 of the package, accordingly, the bending thereof in the perpendicular direction at the root portion 5a is conducted before the bending of the fore end portion 5b thereof. Therefore, a lead holding member 6a can be made to contact with the root portion 5a of the lead 5 in this bending process without obstruction by the fore end portion 5b thereof. Thereby the lead 5 can be fixed surely when the lead 5 is bent in the perpendicular direction in which the separation thereof from the package tends to occur most frequency, and thus the separation of the lead 5 from the main body 2 of the package can be prevented effectively.

Title: Gas instantaneous type hot water feeder
Inventor: TSUTSUI OSAMU
IPC: F23N5/00
Filed: 1984-10-04
Abstract: PURPOSE:To prevent an interruption gap in operation when an ignition in one burner is changed over to an ignition in the other burner by a method wherein a controllable minimum capability of a first burner under a proportional control is made smaller than a maximum capability of a second burner under an intermittent ignition control. CONSTITUTION:A first burner 2 may vary a degree of opening of a proportinal valve 8 when a first solenoid valve 7 is opened and vary a heat amount by varying an amount of gas being supplied. The second burner 3 performs an intermittent ignition by repeating an opening or closing of a second solenoid valve 10 and can vary a heat amount in response to a ratio between a time when the flame is kept and a time when the flame is put out. Since the first burner 2 is constituted such that its minimum capability is lower than a heat amount obtained under a continuous combustion in the second burner 3, that is, the maximum capability of the second burner 3, it is possible to control the capability from minimum to maximum values without interruption in response to the required heat amount.
