Title: Magnetic head slider
Inventor: TAKEUCHI YOSHINORI
IPC: G11B5/60
Filed: 1985-03-29
Abstract: PURPOSE:To attain the external control of the negative buoyancy by adding a negative buoyance control means to a negative buoyancy reduction means set at a floating surface part where the negative buoyance is produced. CONSTITUTION:A venthole 6 serving as a negative buoyancy reduction means is drilled at a negative pressure pocket part enclosed by a flat slider part 2 and a cross rail part 4. An electrostrictive element 8, for instance, is provided on the upper surface part of the venthole 6 as a negative buoyancy control means. A power supply 9 is connected to the element 8 via a switch 10. The negative buoyance is minimized in a start and stop modes and at a low speed mode to float a head quickly. Therefore the switch 10 is turned on to deform the element 8 and to open the venthole 6. The switch 10 is turned off at a steady operation speed to reset the element 8 to its original form. Then the venthole 6 is closed to produce the negative buoyancy. Thus the variance of the floating degree is minimized for the head.

SOLUTION: A cylinder 1 is constructed in such a manner that three cylinders each having a radium R are laid over one another by an amount equivalent to 1/4 of each circumference, laminated portions are eliminated and a suction port and discharge port opened/closed by a suction valve 10 and a discharge valve 11 are formed diagonally to four spots in which the cylinders cross one another. Two projected and recessed plugs 8 and 9 are housed in the cylinder 1 so as to be freely rotated and the projected plug 8 is rotated at a speed twice as fast as the recessed plug 9. This plug is formed in such a shape that when the cylinders each having a radium R are linearly arrayed for each √ 2 times of an axial interval as a radius R and the plugs 8 and 9 are interlockingly rotated, laminated portions are eliminated one by one.

Filed: 1990-03-16
Abstract: PURPOSE:To improve the dimensional accuracy of wire rod by providing small diameter roll for light draft rolling just behind the rolling roll on the preceding stage of a block mill for rolling wire rod. CONSTITUTION:The small diameter roll 5 for light draft rolling is provided just behind the rolling roll which is provided on the preceding stage of the finishing block mill 4. The dimensional accuracy of product on the outlet side of block mill is greately affected by the dimension of intermediate rolled steel material on the inlet side of block mill.

The application of light draft rolling to the intermediate rolled steel material on the inlet side of block mill is very effective to the stability of the dimension of the product on the outlet side of block mill. In this way, the dimensional accuracy of wire rod can be improved with a simple equipment.

IPC: H03K17/00
Filed: 1999-03-11
Abstract: PROBLEM TO BE SOLVED: To obtain an analog switch circuit reduced in a circuit scale without degrading performance by providing a synthesizing means which inverts one of the outputs of first and second switches, and synthesizes those outputs. SOLUTION: An analog input signal j is switched by a switch 12 according to a switch switching signal q from the outside part. The 0 level of the analog signal is inputted to a switch 13, and a switching operation is executed according to the switch switching signal q. Not only a switched signal k but also a switch switching leakage signal s are generated from the output of the switch 12, and only a switch switching leakage signal s' is generated from the output of the switch 13 according to those switching operations. Those switch switching leakage signals s and s' are both obtained according to the switch switching signal q so that the correlation can be made strong. Therefore, they are inverted and synthesized by an inverter/synthesizer 14 so that the switch switching leakage signal s can be almost canceled.

IPC: H01L25/07
Filed: 1978-05-29
Abstract: PURPOSE: To adhere strongly an iron alloy electrode to semiconductor pellet by interposing a high melting metal thin film between semicondutor pellet and electrode.  
     CONSTITUTION: A high melting metal thin film, as, for example, of molybdenum, tungsten, etc., which serves as a shield to hinder the diffusion of the inclusions of electrode into semiconductor pellet or the alloying of semiconductor pellet, is interposed between the semiconductor pellet 1 and the electrodes 2a and 2b in a glass mold type semiconductor device. The use of such a thin film prevents any damage to semiconductor pellet, permits a strong adhesion between an iron alloy electrode and semiconductor pellet by means of a hard solder, and reduces the amount of comparatively expensive high melting metal such as molybdenum, tungsten, etc., to be used. In addition, the use of an iron alloy electrode makes the manufacturing cost lower than the conventional types.

Abstract: PURPOSE:To measure a flow rate and to find water leakage efficiently without making any cyclic check on water leakage by providing a storage part which is stored with a water leakage signal and a flow rate signal and a transmitting circuit which transmits its storage contents through a telephone circuit. CONSTITUTION:The water meter consists of a leak water detecting part 19 and a flow rate measuring part 39 connected to a water pipe. Oscillations which are generated owing to water leak and propagate in water and the pipe wall are detected by a sensor 21, whose output is amplified by a waveform shaping circuit; and only the principal frequency component is passed through a band-pass filter. Its output is supplied to an absolute value amplifying circuit to convert its negative signal into a positive signal, which is compared by a comparing circuit with a specific reference voltage to obtain a decision signal. The continuance of the signal is integrated by a signal continuance integrating circuit 23 and compared with a preset reference value by a water leakage decision circuit 24 to discriminate between a noise and a water leak sound. Then, a water leakage signal storage circuit 32 counts and stores the frequency of water leakage decision and a transmitting circuit 34 sends it to a CPU connected to a telephone circuit together with the storage contents of the measurement signal of the measuring part 39 continuously in specific order in response to a command from the CPU.

Title: Unidirectional heat transfer device
Inventor: YAMAMOTO MASAHIKO
IPC: F28F13/00
Filed: 1980-05-15
Abstract: PURPOSE: To perform unidirectional heat transfer even if the temperatures of heating unit and heated unit are sequentially varied by so arranging the first wall and the second wall disposed at the heating unit side and the heated unit side respectively that a gap occurs between both the walls and the walls are bent toward the heated unit side in a convex manner.  
     CONSTITUTION: The first wall 4 is so bent by the elastic force of a tension spring 12 that its legs 11 make contact with the wall. A uniform gap 10 and hence an air layer is formed between the first wall 4 and the second wall 5. Solar heat A 1  heats the second wall 5 and heats the first wall 4 via the convection heat transfer of the air layer. Water B 1  from a heated unit supply tube 7 flows through a heated unit flow space 6, absorbs the heat of the first wall 4 in the meantime, and exhausts hot water b 1  from a heated unit exhaust tube 8. When the second wall 5 receives high solar heat A 2 , it is thermally expanded to reduce its height, the gap 10 will thus decrease, accordingly most of the second wall 5 will make contact with the first wall 4 at high temperature directly, thereby obtaining high temperature water b 2 .
