Title: Magnetic video recording and reproducing device
Inventor: IKEDA SUSUMU
IPC: G11B15/467
Filed: 1982-12-29
Abstract: PURPOSE:To realize stable slow and still reproduction by operating a delay circuit by 2nd control signal from the final, and switching to a speed reduction state at the completion of a delay time to stop a tape. CONSTITUTION:Two-frame feed is employed instead of conventional one-frame feed and a slow tracking monostable multivibrator 4 is operated by the 1st reproduced control signal between two reproduced control signals which appear in a feed period. Namely, two reproduced control signals are outputted in the tape feed period because of the two-frame feed. The 2nd reproduced control signal is reproduced in a speed reduction period, so this is not utilized and the monostable multivibrator 4 is operated by the 1st control signal; and the length of the output signal (j) of this monostable multivibrator 4 is set longer than before. Thus, stable slow and still reproduction is realized.

Title: Electrophotographic developing system
Inventor: OHASHI TSUTOMU
IPC: G03G13/10
Filed: 1989-09-07
Abstract: PURPOSE:To constantly obtain a satisfactory picture without soiling the surface of a photosensitive body by inserting an output sheet between the photosensitive body and toner at the time of development and directly developing an electrostatic latent image on the output sheet with the aid of the dielectric polarization of the output sheet. CONSTITUTION:A bias voltage is applied to a development electrode 11, which is arranged opposite to the photosensitive body 3 to form an electric field between the development electrode 11 and the photosensitive body 3. When an electrostatic latent image on the photosensitive body is about to pass by the electric field, the output sheet 21 is inserted between the photosensitive body 3 and toner. With the output sheet, the dielectric polarization is generated by the electric field and the electrostatic latent image on the photosensitive body. Consequently, the dielectric polarization of the output sheet 21 artificially brings the electrostatic latent image to the toner side of the output sheet 21, and the toner attaches to a toner requiring part of the electrostatic latent image artificially formed on the toner side of the output sheet 21, because of its static electricity and the electric field. Ultimately a picture is formed on the output sheet. Consequently, a satisfactory picture can be constantly obtained without soiling the surface of the photosensitive body.

Title: Decarburizing treatment of surface with white pig iron casting member
Inventor: KUBO NAOMI
IPC: C21D3/04
Filed: 1983-12-08
Abstract: PURPOSE:To make a white pig iron casting member weldable, solderable and platable by subjecting the white pig iron casting member which is decarburized by dipping successively said member into a heated aq. soln. of chromic acid and an aq. H2O2 soln. having a prescribed concn. to a heating treatment in a neutral atmosphere furnace by conversion of butane, etc. thereby converting the surface of the white pig iron casting to malleable cast iron structure. CONSTITUTION:A white pig iron casting is dipped, as a primary treatment, for 10-20hr in an aq. chromic acid soln. having 600-900g/l concn. kept at 80-90 deg.C and is thereby removing graphite. The white pig iron casting after the primary treatment is dipped for about 4-8hr in an aq. H2O2 soln. having <=30% concn. to force out the graphite remaining in the inside to the outside, by which the white pig iron is thoroughly decarburized. The white pig iron casting after the secondary decarburization is charged into a neutral atmosphere furnace by butane or propane conversion and is subjected to a heating treatment for >=8hr at 700-850 deg.C and is thereafter slowly cooled in air. The cementite on the surface of the white pig iron is consequently thoroughly decomposed and decarburized and is thus converted to ferrite. More specifically, carbonaceous material does not exist in the casting surface after the decarburization treatment and therefore the plating of the white pig iron casting to other metallic member by welding and brazing or plating to the surface is made possible.

Filed: 1985-10-18
Abstract: PURPOSE:To prevent cracks and crystal defects from being generated in the process of recrystallization, by exposing both sides of side walls on grooves formed in a silicon wafer to make single crystal silicon grow on the single crystal. CONSTITUTION:A number of parallel groove 12 partitioned by side walls 13 are formed in a silicon wafer 11. A silicon nitriding film 14 and an SiO2 film 15, which are sued as masks during formation of the grooves, are left as they are, and a nitriding film 16 is made to grow all over the surface, and then the nitriding film 16 is left on only sides walls 13 on the grooves. And, the bottom surface of the groves are oxidized to form an insulating film 17, whose thickness T has a relation W/2<=T with width W of the side wall on the grooves. Then, the nitriding film 16, SiO2 film 15, and nitriding film 14 are removed and a single crystal silicon 18 is made to grow all over the surface so that a desirable isolation layer 19 is formed to make element-formation region 20. Hence, single crystal silicon, in which cracks and crystal defects are prevented from invading the insulating film, can be formed.

Title: Observing method through use of positron reemission microscope and positron beam
Inventor: HIROSE MASAFUMI
IPC: G01N23/04
Filed: 1999-08-19
Abstract: PROBLEM TO BE SOLVED: To observe a material of a positive work function to positrons by holding a sample at the incident location of a positron beam, generating an electric field in a pace close to the sample, and accelerating and observing positrons reemitted from the sample. SOLUTION: A sample 10 of a positive work function to positrons held at a sample holding base 3 is irradiated with a positron beam 2 emitted from a positron beam source 1, and an electron lens 5 and screen 7 are arranged on the downstream side of the sample 10. The sample 10 is brought into a high potential side by a high voltage power source 8 to generate an electric field toward the screen 7. Then when the electric field is strengthened, an apparent work function is reduced and a distance is shortened. A potential barrier in the vicinity of the surfaces of the sample 10 is lowered and thinned when viewed from the positrons, and positrons 4 inside the sample 10 are reemitted by the tunnel effect when the potential barrier is thinned.  As a beam of the reemitted positrons 4 is enlarged and projected onto the screen 7 by the electron lens 5, it becomes possible to obtain information on impurities, etc., in the surfaces from the projected images.

Title: Voltage controlled oscillator
Inventor: HAYASHI TOSHIO
IPC: H03K5/13
Filed: 1987-09-16
Abstract: PURPOSE:To stably perform the oscillation of a low frequency with a few quantity of hardware and to expand the variable range of the frequency, by inserting a device to control an oscillation frequency between an active device in the inside of an inverter circuit and the output terminal of an inverter. CONSTITUTION:The odd number of inverter circuits 1 are connected in ring shape, and at least one or more of them are provided with constitution in which the delay time of the inverter circuit is set variable by the input of a control voltage Vc, and no change of the delay time is generated in remaining inverter circuits 1. By decreasing the voltage of a terminal 6 connected to the gate of a p-ch transistor(TR) M3, a resistance value between the source and the drain of the TRM3 is decreased, and a gate delay time as the inverter circuit is reduced, and similarly, by increasing the voltage of a terminal 7 connected to the gate of a p-ch TrM4, the delay time is reduced, thereby, the oscillation frequency can be varied. Also, since the TRs M3 and M4 act as variable resistors, the amplitude of an output terminal 10 at the time of oscillation is set equal to a source voltage, therefore, the amplitude in low frequency oscillation is not reduced.
