Title: Light guiding device for photothyristor
Inventor: HASHIMOTO OSAMU
IPC: H01L29/74
Filed: 1981-05-22
Abstract: PURPOSE:To improve the transmission efficiency of a light guiding device for a photothyristor by contacting an optical fiber made of a quartz rod core using an air layer of concentrical shape with the clad of outer periphery when the optical fiber for transmitting a gate signal light is disposed at the gate of the photothyristor. CONSTITUTION:A photothyristor 12 is secured onto an electrode base 11, and the photothyristor 12 is surrounded by a cylindrical case 13 disposed on the base 11 at the lower end. A metallic sleeve 14 is passed through the upper end of the case 13, and the lower end of the optical fiber 15 inserted into the sleeve is approached to the gate of the photothyristor 12. In this structure, the optical fiber 15 is made of a quartz tube 17 to which a quarts rod 16 is coaxially inserted to become a core, both ends 19, 20 are welded over the entire periphery, and air is filled in the space 18 between the rod 16 and the tube 17. In this manner, the air layer is used as a clad, thereby reducing the critical angle of causing total reflection of the light ray. Thus, the light transmitted out of the rod 16 is reduced, thereby enhancing the transmission efficiency of the optical fiber.

Abstract: PURPOSE: To obtain pictures that have high resolution and high sharpness, by setting the dimensions of each electrode forming electron lenses within specified prescribed ranges.  
     CONSTITUTION: The length L 5  of the fifth grid 5 is set within ranges decided in accordance with an expression I that the spherical aberration of uni-potential type  electron lenses formed at the fourthWthe sixth grids 4W6 becomes smaller and can  lower focus voltage Ef as much as possible. The length L 6  of the sixth grid 6 can  freely be set comparatively, but it is set in approximate extent that satisfies L 6 /D≥1  in order to prevent effect to the electric fields of lens ranges from the screen side.  The length L 4  of the fourth grid 4 is set so that L 4 ≤L 3 <L 5  be formed in Ef/Eb≤ 0.33 in response to a focus voltage ratio Ef/Eb. Thus, pictures that have high resolution and high sharpness can be obtained by setting the length of each electrode within prescribed ranges.

Title: Magnetic tape recording and reproducing device
Inventor: ARAKI SHIGERU
IPC: H04N9/888
Filed: 1982-05-10
Abstract: PURPOSE:To reproduce a digital TV signal free from a conspicuous error, by making a primary interpolation with the reproduction information of another channel to give a correction to the reproduction information in an error information period due to a dropout. CONSTITUTION:The error signal given from a gate 61 and containing an enlarged dropout signal is supplied to a correcting circuit 641 to receive an error correction, and a remaining error through deletion is fed to an error primary interpolation correcting circuit 651. The circuit 651 gives a primary interpolation correction to the remaining error with a reproducing signal given from the circuit 641 as wall as an error signal which delected a processed error by the circuit 641 and contains an enlarged dropout signal. The primary interpolation is performed by replacing a signal to be compensated with a signal obtained by adding adjacent data to each other and then dividing them by 2. A digital data thus corrected and compensated is delivered through terminals 681-683 as luminance, red and blue signals respectively. In such a way, it is possible to reproduce a digital TV signal free from a conspicuous error.

IPC: F25D9/00
Filed: 1994-04-18
Abstract: PURPOSE:To recover refrigerant, settled on the bottom of a water tank, and return it to a refrigerating cycle. CONSTITUTION:A pressure P1 in a space 3, upper than the water level of a cooling tank 1 for cooling water 2b by the direct contact with hardly water-soluble refrigerant 2c having a specific gravity larger than water, is kept below the saturation pressure Po or less (P1<=Po) of the refrigerant 2c at the solidifying point of water. A nozzle 5, injecting the refrigerant 2c and water 2b into the cooling tank 1, is attached in the cooling tank 1 while a refrigerant ascending flow passage 30 is provided from the bottom of the cooling tank 1 to the water level of the same. The water 2b is cooled by the latent heat of evaporation of the refrigerant 2c, ejected out of the nozzle 5. The refrigerant 2c, not evaporated in the space 3 upper than the water level and settled on the bottom of the cooling tank, is boiled by the reduction and the like of a pressure in the space 3 upper than the water level and generated refrigerant gas is guided into an ascending flow passage 30 to form ascending flow and return the settled refrigerant 2c into a cooling cycle. When the ascending flow is generated once, the ascending flow induces the settled refrigerant 2c and ascends it thereafter whereby boiling can be promoted.

Title: Refresh circuit of dynamic random access memory
Inventor: HOGIYAMA YASUHIRO
IPC: G11C11/34
Filed: 1984-04-18
Abstract: PURPOSE:To decrease the number of input pins and patterns in case the number of refresh addresses is increased by an additional circuit, by using the signals delivered from a gate means as the high order bits of a refresh address. CONSTITUTION:Both a memory request signal MREQ and a refresh signal RFSH are supplied to a gate 21 of double input, and the output of the gate 21 is supplied to an FF22 as a clock signal. While the address data A6 (the data to be used as the most significant bit of a refresh address) is supplied to a D input terminal of the FF22. The FF22 reproduces the data A6, and this reproduced data is divided down to 1/2 by an FF23. Then address bits A0-A6 rise up simultaneously with the rise of a Q ouput A7' and is set at ''1''. Then a signal A7 and the output A7' are multiplexed through gates 4-7. Thus a refresh address signal AR7 is obtained with the timing exactly equal to that of a circuit using a multi-input NAND gate.

IPC: G01S15/08
Filed: 1983-05-09
Abstract: PURPOSE:To measure a correct time interval by enabling the measurement of clock pulses even deviated by one wave-length utilizing a time interval expansion circuit. CONSTITUTION:A counter 4 counts the number A of incoming clock pulses. On the other hand, a transmission pulse P1 and a reception pulse R2 are applied to a set terminal S of a second flip flop circuit 2 through an OR circuit 6 while a clock pulse is applied to a reset terminal R. This produces an output which turns ON by a time t1 until the rise time of one-shot clock pulse following the transmission pulse P1 starting from the rise time of the transmission pulse P1 and an output turning ON by the time t2 likewise for the reception pulse R1. These outputs are applied to an integrator 7 as input and after integrated, they are converted to a digital value from an analog value with a A/D converter 8 and applied to a subtractor 5. Proper selection of the resolution for the A/D converter 8 enables the processing of data at the magnification rate, for example, (m) times determined by the resolution, namely by multiplying t1 (m) times.
