Inventor: KANBARA TETSUO
IPC: B06B1/06
Filed: 1997-07-24
Abstract: PROBLEM TO BE SOLVED: To obtain a rod displacement speed with a moving speed in one direction ('go' during vibration) and other moving speed to another direction ('return' during vibration) which are relatively different, without adopting a voltage control circuit having a complicated configuration.

Abstract: PROBLEM TO BE SOLVED: To eliminate the waiting time after completing a weighing process and to execute the formation of a metal under the most suitable condition by immediately injecting into a die after completing the weighing process in a cylinder by an injection mechanism. SOLUTION: After completing a die closing process with a die clamping device in a thixo-molding apparatus, the weighing process by the injection mechanism is started and completed, and immediately after that, the injection process is executed. In the injection process, metallic material is filled into the die and a metallic product is formed through a pressure holding process and a cooling process. Thereafter, the die is opened with a die opening process, and the metallic formed product is taken out from the die with an ejecting process. Releasing agent is applied into the die after taking out the formed product and again, the die closing process is executed to execute the preparation of the following metal formation.  Since the injection process is applied immediately after completing the weighing process, the metallic material is injected in the optimum condition having the lowest viscosity and the metal formation having good quality can be executed.

Title: Method and device for generating flowrate pulse and/or electronic-type gas meter
Inventor: TANAKA SHINICHI
IPC: G01F1/00
Filed: 1999-07-13
Abstract: PROBLEM TO BE SOLVED: To obtain flowrate pulse generation method and device and/or an electronic-type gas meter that can generate a flowrate pulse with a period according to the passing volume of gas without shortening a sampling period. SOLUTION: Every time when a calculation means 14a-1 intermittently calculates passing volume at a fixed period, a calculation means 14a-2 calculates the 1/N value of the passing volume. Until an integrating means 14a-3 integrates the 1/N value for N times, a counter means 14a-4 repeatedly counts the number of times of integration where an integration value reaches unit passing volume/2 or more. Until the integration is made for N times, every time when the unit passing volume/2 is reached, a subtraction means 14a-5 repeatedly subtracts the value of the unit passing volume/2 from the integration value. A decision means 14a-6 multiplies the number of integration times by a fixed period, 1/N, for determining an output reversal timing to the next.  A pulse generation means 14a-7 reverses output at the decision timing for generating the flowrate pulse of a period corresponding to the passing volume.

Title: Target for manufacture of magnetic head and manufacture of magnetic head
Inventor: BEPPU FUMIAKI
IPC: G11B5/85
Filed: 1989-07-31
Abstract: PURPOSE:To prevent anisotropy from being generated in a target surface and to make magnetic properties in a circumferential direction uniform in any part in a disk by forming plural V-shaped grooves in a direction perpendicular to a base moving direction on the target surface. CONSTITUTION:On the target surface, plural V-shaped grooves 1 are formed in the direction perpendicular to the base moving direction. The V-shaped grooves 1 are formed so that a graphical shape for the longitudinal cross section of the target can be sawtooth-shaped. When ion 9 is made incident to an inclined surface 13 at a gradient angle 30 deg. at an incidental angle 30 deg., for this V-shaped groove 1, as the discharge angle distribution of sputter atom, sputter particles are ejected like sputter particle 10,11 and 12 according to a cos(theta-30) rule. The discharge angle distribution of the sputter atom is changed by setting the gradient angle to a suitable value and an initial layer can be formed by the sputter particles which are vertical incident and ejected. Thus, for a magnetic disk medium which initial layer is formed by the particles vertically incident anisotropy is not generated in the surface and the magnetic property in the circumferential direction is made uniform.
