Title: Method of measuring rate of change of emitter-ground dc current amplification factor to dc collector current of transistor
Inventor: KUKI RIYOUHEI
IPC: G01R31/26
Filed: 1978-11-25
Abstract: PURPOSE: To readily measure the rate of change of an emitter-ground DC current amplification factor hFE with respect to the DC collector current of a transistor by the formula 1-hFE/h fe , where h fe =ΔIc/ΔIB.  
     CONSTITUTION: Infinitesimal AC voltage ΔVC generated across a resistor R 3  connected to the collector of a transistor to be measured is rectified into DC via the rectifier 14 of a DC circuit 15 to become DC voltage ΔVC', which is supplied to an arithmetic circuit 16 together with DC voltages VB and VC obtained across resistors R 1  and R 2 , respectively to thereby obtain DC voltage ΔVB' responsive to infinitesimal AC signal base current ΔIB. That is, the arithmetic circuit 16 calculates the value n represented by the formula n=(1-hFE/h fe ) from the DC voltages VB, VC, ΔVB' and ΔVC'. The value n thus obtained represents the rate of change of the emitter-ground DC current amplification factor hFE with respect to the DC collector current IC of the transistor Q to be measured.

Abstract: PURPOSE:To control the vibration of each part, esp. a U-shaped core and a coil, of a printing head caused by a repeat of printing by a method wherein a resin having approximately the same linear expansion coefficient as the U-shaped core is charged between printing wire drive elements of a core base member. CONSTITUTION:The reaction of a printing wire 2 at the impact against an ink ribbon 8, printing paper 9, and a platen 10 from a standby state to a printing state and the collision of an armature 1 against an inner columnar projection part 5b from a printing state to a standby state causes the vibration of each part, esp. a U-shaped core 5 and a coil 6, of a printing head. The coil 6 is embedded in a thermosetting polyester resin molding material (BMC) 11 (a linear expansion coefficient = 0.8 * 10<-5> - 1.5 * 10<-5> (1/ deg.C)). Moreover, said resin is charged up to an end face 54c or thereabout of the inner columnar projection part 5b. In this manner, the vibration of the U-shaped core 5 (material : 3% SiFe, a linear expansion coefficient = 1.2 * 10<-5>) and the coil 6 can be inhibited, and a noise can be prevented.

Title: Method for measuring sintering degree of uranium dioxide powder
Inventor: AOKI KAZUHIRO
IPC: G01N25/02
Filed: 1989-06-08
Abstract: PURPOSE:To measure oxidation starting temperature accurately and simply and to make it possible to automate the operation by heating uranium dioxide (UO2) powder at the temperature increasing speed of 1 - 10 deg.C/mm, and detecting the fact that the powder starts oxidation and blackening with a non-contact type colorimeter/color- difference meter. CONSTITUTION:UO2 powder is picked up by 2 - 30g and mounted uniformly and thinly on a heat resisting and oxidation resisting pan, e.g. a stainless steel pan, which is placed on a plate-shaped heater. Then, the UO2 powder is heated with the heater at the temperature increasing speed of 1 - 10 deg.C/mm. When the powder is heated at said temperature increasing speed, the oxidation of the UO2 powder is started, and the color of the powder becomes black. The change in color is detected with a non- contact type colorimeter/color-difference meter. The temperature of the powder at this time is measured with a radiation thermometer, and the oxidation starting temperature is obtained. The oxidation starting temperature obtained in this way has the very excellent correlation with the sintering degree when the UO2 pellet is manufactured. Therefore, the oxidation starting temperature of the UO2 powder can be the important characteristic value in manufacturing the UO2 pellet.

Title: Production of vapor deposition al-cr alloy plated steel material
Inventor: SATO HIROSHI
IPC: C23C14/14
Filed: 1989-06-08
Abstract: PURPOSE:To apply vapor deposition alloy plating with a uniform and stable composition to the surface of a steel material by heating and evaporating Al and Cr simultaneously from an Al-Cr alloy bath and supplying the above alloy bath with Al and Cr by the amounts corresponding to respective evaporated quantities of Al and Cr. CONSTITUTION:Al and Cr are alloyed and put into the same melting tank to undergo heating by means of electron beam, etc. Respective metallic vapors of Al and Cr are vapor-deposited in a fully mixed state onto a steel sheet. Since Al having higher vapor pressure is evaporated by larger amount than Cr at first and the molten alloy is changed into a Cr-enriched state, Al and Cr are continuously supplied to the alloy tank at velocities corresponding to respective evaporated amounts of Al and Cr. By this method, the composition of the molten Al-Cr alloy is always held constant and fluctuations in the ratio between respective evaporated amounts of Al and Cr are prevented, and, as a result, the composition of the vapor deposition Al-Cr alloy plating to be applied to the steel sheet can be always held constant.

IPC: C09D1/00
Filed: 1996-05-16
Abstract: PROBLEM TO BE SOLVED: To produce a photocatalyst-coated metallic sheet maintaining highly stable oil decomposing capability over a long period. SOLUTION: A TiO2 layer is formed on the surface of a metallic sheet via an SiO2 base layer for suppressing the diffusion of the metal. It is produced in such a manner that silane compounds or SiO2 sols applied on the surface of the metallic sheet are subjected to heat treatment to form the base layer composed of an SiO2 precursory body or SiO2 , which is thereafter coated with organic titanium compounds or titania sols, then, heat treatment is executed, TiO2 is baked to the metallic sheet while the diffusion of the metal from the metallic sheet is suppressed by the base layer. Since the diffusion of the metal is suppressed by the SiO2 layer, there is no reduction in the catalytic activity of TiO2 .

Title: Flow rate proportional control valve unit
Inventor: HASHIMOTO KENJI
IPC: G05D7/00
Filed: 1978-11-27
Abstract: PURPOSE: To prevent the plunger of a flow rate proportional control valve unit from sticking or attracting thereto by communicating a valve chamber for containing the valve portion of the plunger wound with an electromagnetic coil with an electromagnetic chamber for containing the electromagnetic coil to thereby balance between the hydraulic pressures of both the chambers.  
     CONSTITUTION: A magnetic circuit is formed through a plunger 14 and a body 11 by magnetic flux generated from a permanent magnet 17 normally, and partially passed through an electromanetic coil 16. When a current is applied to the coil 16 at this time, a magnetomotive force proportional to the applied current is generated thereat. Accordingly, the plunger 14 is moved rightwardly against srings 19, 20. Thus, the valve portion 14a opens a fluid passage 18 to thus control the openig area so as to thereby control the fluid flow rate communicating between the ports 12 and 13. Since the valve chamber 24 communicates through the passage 26 with the electromagnetic chamber 25 at this time, the hydraulic pressures between the chambers 25 and 26 are balanced to eliminate the pressure difference therebetween to thus perform the above purpose.

Abstract: PURPOSE:To improve the recording capacity and to ensure easy and assured control of revolutions in a reproduction mode for an information recording/ reproducing device, by controlling in steps the revolutions of a disk so as to obtain an integer number of sectors which are recorded on one round of the disk as well as to obtain approximately a fixed disk linear speed to a recording/ reproducing head. CONSTITUTION:In a reproduction mode, an electric signal modulated in response to the presence or absence of a bit is extracted through a read control circuit 213. A blank signal is detected out of the electric signal by a blank detecting circuit 211, and the sector start position is detected. The detected blank signal is transferred to a sector control part 12 and at the same time demodulated by the circuit 213. The information data is transferred for each sector to an information input/output part 13 via a read data buffer 212. A blank counter 214 counts the number of sectors existing on one round of a concentric recording track from the detected blank signal of a revolution reference signal with which a revolution reference mark is detected by a detector 2 and then transfers the data to a revolution control part 9. As a result, the revolution can be accurately controlled in a reproduction mode.

As shown in figures (a)-(c), the timing when the carry signal CY is generated is shifted from the block switching timing. Thus, the DC regeneration circuit DA does not sample a noise NZ and the effect of the noise NZ on a picture signal Va is prevented.
