IPC: G11B5/39
Filed: 1997-10-14
Abstract: PROBLEM TO BE SOLVED: To prevent electrostatic breakdown in an MR element on a substrate while forming and to manufacture it in high yield by forming a conductive pattern longer than a conductive path consisting of the MR element and a pair of electrodes on the substrate provided with plural MR heads having a pair of electrodes electrically connected to the MR element.

Title: Tape cassette
Inventor: FUJII HIROSHI
IPC: G11B23/04
Filed: 1993-10-15
Abstract: PURPOSE:To enable the use of large and small cassettes by forming engaging notched parts on an abutting part for positioning the small cassette and the lower edge of the front surface of a cover. CONSTITUTION:When the tape cassette T is loaded on a recording/reproducing device, the abutting part for positioning the small tape cassette abuts on the front surface 16a of the part 16 to be abutted, and the abutting part 46 for positioning the large tape cassette abuts on the front surface 15a of the part to be abutted, then the cassette T is positioned. In the closed state of the cover 21, the lower end part on the front surface part 25 of a front lid 22 is abutted on the front surface of the part 17 of a lower half 4, therefore, the extensive deflection does not occur and there is no unrest in the strength since the front surface 25 abuts on the part 17 even through it is pressed from the front side. Since the notched part on the front surface part 25 of the front lid 22 is engaged with the abutting parts 15, 16 of a case 2 and the half 4 is located at the back side between the notched parts 30, 31, the space produced when the cover 21 is slightly moved is limited to the small extent, so the dust-proof property is almost not impaired. Thus, the stable positioning is executed and also the dust proof-property is ensured.

Abstract: PURPOSE: To enable control of the movement of a door by providing a shaft, which is slidably and rotatably received in a hole formed in a floor under the door in a closed position, and connecting a cross-member onto a cylindrical portion of the shaft. CONSTITUTION: A shaft 11, vertically extending and having a cylindrical lower portion 17, is disposed in a tubular receptacle 12. The lower portion 17 is received slidably and rotatably in a hole 13 formed in a floor 14 proximal a lower edge 15 of a door 16, when it is in a closed position. Then, a cross- member 23 is formed in a manner horizontally extending with respect to the shaft 11 and being rigidly connected to the shaft 11 on the cylindrical lower portion 17. Next, during operation, the shaft 11 is inserted into the receptacle 12, when the door 16 is in the closed position. When the door 16 is partially opened, it is brought into contact with the edge of the cross-member 23, and the opening door 16 makes planar contact with the cross-member 23 to rotate the same.  Thus, the movement of the door 16 is stopped, by making planar contact with the shaft 11 by a force placed on the door 16, which is distributed over a relatively large surface area thereof.

Title: Flow rate control nozzle
Inventor: KOBAYASHI HIROSHI
IPC: B05B1/34
Filed: 1988-11-08
Abstract: PURPOSE:To widen a flow rate control range by a method wherein, in the title nozzle for a petroleum proportional control burner, a needle for varying a flow passage area in the side of which a recessed part for a flow passage is formed and the tip of which is flat is forward and backward movably situated in a revolving chamber, formed in the tip of a nozzle, in a state to make contact with a distributor. CONSTITUTION:With a drive means moved forward and backward by means of a needle 12, the area of a flow passage formed with a recessed part 11, formed in the side of the needle 12 and a distributor 9, is changed to control a spray amount. In this case, since a tip surface 10 of the needle 12 is formed in a planelike manner and the needle 12 is always brought into contact with the distributor 9, the tip of the needle 12 is prevented from swing. Thus, there is neither change in a spray pattern and a spray angle nor change in combustion performance. This constitution enables regulation of a spray amount throughout a wide range and permits the prevention of the occurrence of vibration combustion and the generation of noise.

Title: Pretreatment of cation analyzer
Inventor: KUMAMARU NAOHIRO
IPC: G01N30/02
Filed: 1989-10-31
Abstract: PURPOSE:To achieve an accurate analysis of cations existing in a reagent in a strong acid by using an electric dialyzer with an anode chamber, a cathode chamber and a sample chamber to perform a neutrization by electric dialysis. CONSTITUTION:As an electric dialyzer is energized electrically, hydroxide ions in a cathode chamber 3 move to a sample chamber 2 passing through an anion exchange membrane 5. On the other hand, anions contained in a sample liquid move to an anode chamber 1 passing through an anion exchange membrane 4 from the sample chamber 2. Therefore, the anions existing originally in the sample liquid is replaced with the hydroxide ions being supplied from the cathode chamber 3 with elapse of time. Thus, the sample liquid is neutralized. At this point, when arranged at optional positions of a feed liquid line 12, an ion sensor, an electric conductivity detector or a pH meter allows the monitoring of neutral condition in the sample liquid simultaneously with the start of operation.
