Title: Forging of microcrystalline titanium powder and method of its manufacture
Inventor: PURABIAA AARU BUHOWARU
IPC: C22C14/00
Filed: 1990-09-14
Abstract: PURPOSE: To obtain fine crystal grain Ti forgings having improved acoustic wave performance by heating a billet of a selected Ti-base alloy to a specific temp., subjecting this billet to forging pressing and holding the billet at an adequate temp. for an adequate time, then rapidly cooling the billet.  
     CONSTITUTION: The billet of the Ti-base alloy is selected. This billet is heated up to the first temp. in a range from a temp. to transform the billet 100% to β up to about 38°C above the β transformation temp. The billet is pressed by a forging press heated up to the second temp. of this temp. range. The billet is then held at the third temp. in the range described above for the time to allow the collision of the recrystallized crystal grains against each other and insufficient for the further crystal grain growth. The billet is thereafter rapidly cooled down to the fourth temp. lower than the β transformation temp. to prohibit crystal grain growth and to establish the max. preferential β grain size. As a result, the Ti forgings having the max. preferential β grain sizes below 0.5mm are obtd. The first, second and third temps., are set substantially equal to each other. The produces are used for applications for space aircraft, etc.

Title: Optical disk
Inventor: TANAKA KUNIMARO
IPC: G11B7/24097
Filed: 1986-10-16
Abstract: PURPOSE:To correct a tracking by forming a section without a guide groove in one circumference at every specified section at a path where the guide groove of an optical disk is formed, forming a radiation band in parallel in a radius direction and providing a correcting groove as per the prescribed way in the middle of the path, in which a guide groove is formed, and the adjoining path at the radiation band. CONSTITUTION:At a path 31, in which a guide groove 1 is formed, a section 32 without an integer number of grooves 1 in one circumference at every a specified angle, the section without grooves is arranged in a radius direction and a radiation band 33 is formed. At the center of the interval of the adjoining grooves 1, further, from the edge to the edge of the inner circumference of the radiation band, a correcting groove 34 is provided at the radiation band 33. For the correcting groove 34, a cross section is the same as that of the guide groove 1. According to the constitution, since the part having no groove does not exist as seen in a mirror system and a wobbling pit system, a track counting error does not occur. When a disk is not inclined and an optical beam runs on the groove 34, the difference signal of a two-division detecting device is 0 (point 36), at the time of inclination, a position dislocation (d) occurs, a tracking servo is operated by a point 40 (41) immediately on the point 36 and the dislocation can be corrected.

Title: Manufacture of granulated zinc alloy for alkaline battery
Inventor: SHINODA KENICHI
IPC: H01M4/42
Filed: 1985-11-01
Abstract: PURPOSE:To improve a leakage-resisting property of a battery in case of being used as a negative polar active material, by annealing specific granulated zinc alloy at 100-420 deg.C and the performing alkaline treatment so that amount of generating hydrogen gas can be extremely reduced, without discharge performance being deteriorated, while it being low hardened and stored or so. CONSTITUTION:A granulated zinc alloy, which contains zinc as a main element and one or two kinds or more of elements selected from a group of iron, cadmium, lead, bismuth, gallium, indium, thallium, tin, magnesium, aluminum, is annealed at 100-420 deg.C, and then treated with alkali. When an annealing temperature is below 100 deg.C, recrystallization of the granular alloy of zinc becomes insufficient, and on the other hand when it being above 420 deg.C, the granulated zinc alloy becomes molten-cohesive. And, with alkaline treatment being performed, highly reactive grains can be made to react in advance, to remove harmful impurities existing in the granular region so that gases can be prevented from being generated while the alloy being assembled in a battery.

Title: Control method for stepping motor
Inventor: SEKIGUCHI KAZUHIRO
IPC: H02P8/38
Filed: 1996-09-19
Abstract: PROBLEM TO BE SOLVED: To provide a control method for a motor in which the step-out phenomenon unique to a stepping motor can be avoided. SOLUTION: A target speed V** delivered from a stepping motor control circuit is compared with the actual current speed V of a stepping motor. When the actual speed is lower that the target speed, a decision is made that a step- out phenomenon will take place at high possibility and a command speed V* is determined according to a formula; V*=V+δv, where, (V is actual speed, V* is a command aped according to the control method, and δv is a micro speed increment). When a command speed V* thus obtained satisfies a relationship V*<=V**, that command speed is employed as a target speed in the control of the stepping motor.

Inventor: BUIRUHERUMU NITSUCHI
IPC: G03F3/10
Filed: 1993-09-09
Abstract: PURPOSE: To obtain the method and instrument for measuring the optical density of an original picture specially of a tricolor negative from which a photographic print is made, and detect high intensity for each pixel with few calculations. CONSTITUTION: When an image is projected on a color print medium which senses its colors, the amounts of printing light of the respective colors transmitted through the original picture 5 are controlled. The spectrum sensitivity of this measuring instrument is adjusted to the spectrum sensitivity of the print medium. Measurement light is projected through the original picture 5 and decomposed into at least one spectrum. The intensity of light in various wavelength ranges is weighted, according to the spectrum sensitivity of a specific print medium and totalized. Light valves having translucency adjusted within the wavelength range of the spectrum sensitivity of the print medium are distributed along the spectrum. The intensity of light of each color which is thus weighted is individually sensed and measured.

Abstract: PURPOSE:To make a high-speed stable recording easy, by a method wherein a first energy generation is provided along a liquid passage, a second energy generation means which crosses the liquid passage is provided on its upstream side, and the component in the liquid-passage width direction thereof is made wider than a liquid passage width. CONSTITUTION:A second energy generation means 603 for preventing the loss of energy supplied to ink 602 by a discharge energy generation means is so installed as to cross a liquid passage basically on the upstream side of said discharge energy generation means (on the opposite side of a discharge opening). Then, the component Hl in the liquid passage width direction of this second energy generation means 603 is made wider than a liquid passage width Nl.
