Title: Nickel electrode and manufacture thereof
Inventor: YAMAGISHI TOSHIHIKO
IPC: H01M10/39
Filed: 1991-09-17
Abstract: PURPOSE:To provide a high temperature sodium-nickel chloride battery in which nickel positive electrode utilization efficiency exceeding 30% is achieved and which has high energy density and high output density. CONSTITUTION:Nickel foil or a nickel wire is fabricated by the melt spin method. The thickness (or diameter) of the foil or the wire is specified at above 10mum and below 200mum. A nickel electrode is formed by sintering method using the foil. The nickel positive electrode has an appropriate surface area (per unit weight). Since the fine structure of the electrode is uniform, charge and discharge reactions at the nickel electrode uniformly progress and conductivity is secured for almost the whole part of the electrode. The utilization efficiency of the nickel is enhanced by the above-mentioned two reasons.

Abstract: PURPOSE:To use the visual characteristic of human eyes to obtain a satisfactorily compressed picture with a smaller number of bits by limiting the change range of variable density to a minute block unit like a prescribed number of picture elements to quantize each picture element. CONSTITUTION:Data Y is divided into blocks B by a block dividing circuit 22, and a maximum value MAX and a minimum value MIN of data Y in each block B are taken out by a detecting circuit 23.

Title: Data transmission method
Inventor: HARA YOSHIAKI
IPC: H04L9/32
Filed: 1996-09-06
Abstract: PROBLEM TO BE SOLVED: To eliminate a common key controlling work when a transmitter transmits data to a receiver excepting a transmitter oneself by a common key ciphering transmission data and to automatically generating a common key required for a concealing for a third person from data. SOLUTION: When the transmitter transmits the data to the receiver excepting the transmitter oneself, that is, when the open key of the receiver is different from the open key of the transmitter, transmitted signature D4a becomes the contents different from a summary D2a becoming the origin generating the open key D5a. Then, even when the third person having no secret key D10 of the receiver intercepts the signature and the ciphered data while transmitting, the third person can't open key decipher the signature by the secret key D10 of the receiver to can't generate the summary. Thus, since the common key isn't generated from the summary, and the ciphered data aren't common key deciphered, and the data aren't obtained, the contents of the data D1a are concealed for the third person. That is, the attestation of the receiver intended by the transmitter is performed.

Inventor: JITSUZAWA YOSHISUE
IPC: H01L21/22
Filed: 1993-09-22
Abstract: PURPOSE:To prevent a semiconductor wafer from being contaminated by impurities existing in a manufacturing apparatus by a simple method. CONSTITUTION:Silicon oxide films 21 are formed on the surfaces of a boat 19 and an inner silica tube 11 contaminated by a high-melting-point metal (tungsten). And silicon wafers 18e which neither have any tungsten silicide film nor have been contaminated are mounted on the boat 19 and heat-treated (800 deg.C) in a vacuum. The measurement of the degree of contamination on the surfaces of the silicon wafers 18e has proved that it is lower than the detection limit (1E8atom/cm<2>) of a measuring apparatus. Namely. it becomes possible to suppress the scattering of the tungsten contaminating the surfaces of the boat 19 and the inner silica tube 11 by the silicon oxide films 21 covering the surfaces. As the result, it becomes possible to prevent the surfaces of the silicon wafers 18e from being recontaminated.

Title: Production of rock crystal optical low pass filter
Inventor: NAKAI TOSHIYUKI
IPC: G02B27/46
Filed: 1986-10-06
Abstract: PURPOSE:To obtain an inexpensive crystal optical low pass filter by executing black coating of rock crystal plates prior to mirror finishing so that an excess adhesive agent after sticking of the rock crystal plates to each other can be easily removed by cleaning. CONSTITUTION:The rock crystal plate 1 is cut to 2-3mm thickness at 45 deg. angle with the optical axis of the original stone of rock crystal and is worked in outside shape to about 10X12mm. After a black paint 3 is coated on the side faces, the main face is subjected to the mirror finishing. The rock crystal plate 9 after the mirror finishing is stuck by a photosetting adhesive agent 7 such as UV curing adhesive agent and UV rays are projected thereto from the main face to cure the adhesive agent 7. Since the black paint 3 is already coated on the side faces, the incident UV rays from the main face do not transmit the side faces and the adhesive agent 7 leaking on the side faces are hardly curable. Such adhesive agent can be easily removed by the post cleaning.

Title: Ic output circuit
Inventor: ICHIOKA AKIRA
IPC: H03K17/687
Filed: 1996-09-09
Abstract: PROBLEM TO BE SOLVED: To obtain the IC output circuit with small power consumption in which rising/trailing of an external drive output are performed at a high speed. SOLUTION: When a drive input In is at an L level and stable, an FETM6 is conductive, a M3 is nonconductive, and a gate level of an output stage FETM01 is decreased to a GND level with a very small gate current via a large resistance (R5+R6) and the M01 is conductive. Just after a level of a drive input IN decreased from H to L, an output H of the inverter Nq is delayed through inverters N5-N7, an input to the NAND gate G2 goes to H by the delay time and the inverter N10 provides an output of a pulse of an H level with a width of the delay time. A FETM9 short-circuits a resistor R6 only for a pulse output period and a gate current of the output stage FETM01 is increased to quicken turning-on.

Title: Reference processing system for user's inherent condition
Inventor: IMANISHI MAKOTO
IPC: G06F9/06
Filed: 1989-09-13
Abstract: PURPOSE:To reduce the load on a programmer by providing a user's inherent condition master and referring to it by a read-in subroutine, and thus facilitating the processing for the reference and preventing a deadlock from being caused. CONSTITUTION:The user's inherent condition master 4 is an external master file storing user's inherent conditions in the form of unit records. When a main program 2 is executed, processing corresponding to user's inherent conditions is included in main processing and in initialization processing which is carried out prior to it, the user's inherent condition master read-in subroutine 4 is called and executed. Consequently, the user's inherent conditions are read in the read-in subroutine 3 from the user's inherent condition master 4. Consequently, a main program 2 itself need not refer to the user's inherent condition master 4, so the processing for the reference is facilitated and no deadlock is caused, thereby reducing the load on the programmer.

Title: Apparatus for dissolving and injecting solid matter
Inventor: TOYODA TAKASHI
IPC: C23F11/08
Filed: 1987-09-22
Abstract: PURPOSE:To improve the workability of the title device by adjusting the amt. of the solid chemical to be dissolved and injected whose concn. is to be adjusted by the vertical movement of a partition plate provided in the device. CONSTITUTION:A prescribed amt. of a spherical rust-preventive agent 7 such as sodium polyphosphate and polysilicate is charged in a tank 6. When the horizontal partition plate 19A is positioned above a water inlet 10 and a water outlet 11, the ascension of the water flowing in from the water inlet 10 is intercepted by the horizontal partition plate 19A, and the water flows down in the tank 6 along the one sides of a vertical partition plate 19B and a guide part 13. A gap is provided between the bottom of the tank 6 and the guide part 13, and the water flows into the opposite side through the gap and flows up. At this time, the rust-preventive agent 7 is brought into contact with the water and slowly dissolved into the water, and the water ascends in the tank 6 and is discharged into a water supply pipe from the water outlet 11. By this method, the workability can be remarkably improved.
