Title: Production of magnetic recording medium
Inventor: YOSHIMOTO TAKESHI
IPC: G11B5/84
Filed: 1998-05-18
Abstract: PROBLEM TO BE SOLVED: To control the amt. of particles peeled from a substrate in an etching liquid by controlling the etching amt. in the electrolytic etching process to a specified range. SOLUTION: In the production of a magnetic recording medium including a process to subject a conductive substrate to electrolytic etching, the etching amt. in the electrolytic etching process is controlled to 0.005 to <0.015 wt.% to the weight of the conductive substrate. The etching process is preferably carried out after a polishing process or texturing process. If the electrolytic etching amt. is smaller than the lower limit, the surface is not enough smoothened, which decreases gliding characteristics. If the etching amt. exceeds the upper limit, smoothening enough proceeds while particles peeled from the substrate in the electrolytic etching process deposit again on the substrate surface to decrease the gliding characteristics. It is not preferable.

Filed: 1985-06-21
Abstract: PURPOSE:To conductive a further high abrasion resistance and prevention of deterioration of a heating resistor, by providing an abrasion-resisting layer comprising the first protective film consisting of a diamond film and the second protective film adjacent to the first protective layer on the inside, outside or both sides of the first protective layer, on the heating resistor. CONSTITUTION:The protective layer comprises the second protective film 1a provided in a thickness of 2mum and the diamond protective film 1 provided thereon in a thickness of 5mum. Even when the diamond protective film has some pinholes, oxidation of the heating element 3 due to the penetration of oxygen can be prevented, since the element 3 is sealed by the second protective film 1a which is impermeable to gases. The second protective film may be provided on the outside, inside or both sides of the diamond protective film. Accordingly, since the second protective film consisting of a hard glass or the like is added to the diamond protective film having excellent abrasion resistance, thermal conductivity and insulation properties, abrasion resistance is further enhanced, the heating element can be prevented from being deteriorated due to oxidation, and stable and favorable image quality can be maintained for a long period of time.

Abstract: PURPOSE: To obtain a two-wire type vortex flow meter connected to the reception side by means of a pair of transmission lines detecting the fluid vibrations accompanied with the formation for von Karman's vortex streets as alternating charges with a piezoelectric sensor then converting the alternating charages to a DC telegraph signal.  
     CONSTITUTION: When measuring fluid flowes in a pipeline 11, a vortex producing body 12 produces von Karman's vortex streets and receives alternating forces by the fluid vibrations based on the formation of the vortexes. This causes the stress changes produced in the vortexes producing body 12 to be transmitted to a piezo electric element 13 via insulation material 14 and the signal of good S/N is obtainable between lead wires 17a, 17b. The alternating charges (q) of the vortex frequency (f) produced between these lead wires 17a, 17b are applied to a vortex flow meter converter 20. The output current IO of said vortex flow meter converter 20  bocomes the one corresponding accurately to the vortex frequency (f), i.e., the  velocity of flow of the fluid. This output current IO is transmitted to the load on the  reception  side through a pair of transmission lines.

Title: Wiper speed controller
Inventor: ONOKI MIKIO
IPC: B60S1/08
Filed: 1984-07-02
Abstract: PURPOSE:To save the power needed for driving a wiper by providing a car speed discriminating means and controlling speed of the wiper in accordance with the output from said car speed discriminating means. CONSTITUTION:A car speed discriminating means 11 consists of a car speed detector 8 and a comparator 9. The output from the detector 8 is compared with the specified voltage by the comparator 9 and the result, that is, whether the output is higher or lower than the voltage is generated from said means 11. If a wiper speed setting means 2 is kept in a low speed mode 2b and a car speed exceeds a wiper speed changing point, the comparator 9 generates an H level, which is sent to NAND B1. A voltage of an H level is sent to another input terminal of the NAND B1 from the contact of a low-speed mode 2b, on account of which the NAND B1 generates an output of an H level. This output drives a low-speed actuating relay B to close the contact 7b of a wiper driving circuit 10, hence driving the wiper at a low speed.

Title: Toner emptiness detector
Inventor: ISHIDA KAZUYA
IPC: G03G15/08
Filed: 1986-06-11
Abstract: PURPOSE:To accurately inform a toner feeding time by providing the titled detector with a counting mechanism and a control mechanism for detecting the empty state of a toner storing part when the number of times of toner feeding reaches the previously stored number of times of empty. CONSTITUTION:When the quantity of toner fed by a toner cartridge 61 is set to 60g, the quantity of toner fed by one feeding operation is 120mg and toner in the toner cartridge 61 is consumed by 500 times of feeding operation. Therefore, when the number N of counts is >=500, a LED 103 for empty toner display on an operation panel 101 is lighted to inform the replacement of the toner cartridge 61. After extinguishing all LEDs 1-5, the operation is returned. When the number N of counts is <500, the operation is continued without lighting the LED 103. Consequently, the toner consumption and its residue can be accurately informed in both the cases of character originals and solid black copies.
