Title: Mixture of sodium chloride and its preparation
Inventor: TOYODA YUTAKA
IPC: A23L19/20
Filed: 1983-04-30
Abstract: PURPOSE:To improve the adhesivity of salt to the object such as pickled vegetables, etc., and to improve the workability of pickling, etc., by mixing coarse NaCl particles with parched NaCl having small particle diameter, thereby preparing the parched salt containing coarse particles. CONSTITUTION:Formed NaCl obtained by the compression molding of parched salt or raw salt under a pressure of 1.0-3.0t/cm<2> is crushed to obtain coarse NaCl. 3-30wt% of the coarse NaCl coarser than 20 mesh is mixed with >=10wt% of parched NaCl finer than 20 mesh to obtain the objective mixture. EFFECT:Even if the mixture is scattered on the floor during the preparation of pickled vegetables, it does not cause the slip of workers, and is safe in contrast with the case using only the parched salt. When the mixture is used for the melting of snow, it can be scattered uniformly, resulting in high snow-melting effect.

Title: Video signal processor
Inventor: HAYASHI SHUNEI
IPC: H04N7/08
Filed: 1988-03-29
Abstract: PURPOSE:To shorten the developing period and reduce the cost of the title processor by discriminating the category of a control signal by means of a repeater and transmitting the discriminated category to a TV signal processing circuit or decoder for teletext. CONSTITUTION:A control signal S sent from an external remote operation device is first fetched by a repeater 19 and whether the control signal S is the control signal for a processing circuit 17 or for a decoder 18 is discriminated from the category code in the signal S. After discrimination, the decode in the control signal S is transmitted to the processing circuit 17 or decoder 18 after the format of the decode is appropriately transformed. Therefore, when the conventional hardware is combined nearly in the same state, the developing period can be shortened.

Title: Welding method of piping
Inventor: SHIMIZU TASUKU
IPC: B23K31/02
Filed: 1982-05-07
Abstract: PURPOSE:To eliminate the air bubble in the working part on the inside circumferential surface in the welding groove of steel pipes through a water-cooled welding method quickly and to prevent the decrease in heat transfer rate, by requlating the length on one side in said working part and finishing the part within a prescribed distance from the bead end on the inside surface to a specular surface. CONSTITUTION:A welding groove wherein the length L1 in the working part (DC working part) 3 on the inside circumferential surface of the pipe in a welding groove is made >=200mm. and the range 8 of a distance L2 from the toe of weld is finished to a specular surface is formed in the case of adapting a water- cooled welding method in butt welding of steel pipes 1. Flowing water 2 is passed in the pipes 1 in this state and the water-cooled welding in the part 3 is executed. As a result, the generation and stagnation of the bubble near the toe of weld heated to a high temp. in the stage of welding are suppressed and the decrease in the heat transfer rate on the inside surface of the pipe owing to the generation of the air bubble is prevented. The temp. difference in the thickness direction is assured; therefore, the residual stress in the inside surface of the pipe is made compressive over the entire circumference of the pipe.

Title: Method of slicing semiconductor single crystal ingot
Inventor: TOYAMA KOHEI
IPC: B28D5/04
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To prevent crack or fracture by slicing a semiconductor single crystal ingot without conforming the travel direction of a wire saw device with the cleavage direction of the semiconductor single crystal ingot. SOLUTION: A protective plate 41 is joined to a position excepting a position of an orientation flat OF or a position which is displaced from the orientation flat by 90 deg., and this protective plate 41 is joined to an adhesion mount 42. That is, either of the cleavage direction of A1 or A2, for example an angle θ between A1 and the travel direction Y of a wire of the wire saw device is 5 or more. Therefore, a saw mark made by the wire of the wire device is not so conformed with the cleavage direction of the ingot W as the ingot does not crack nor broken in a wafer produced by slicing the ingot W.

Title: Area error decision system for write instruction
Inventor: AKAMATSU KENICHI
IPC: G06F11/00
Filed: 1988-03-29
Abstract: PURPOSE:To prevent the area error of a write instruction by arbitrarily designating an area, where write from a program is permitted, to easily detect the outside of the range of the preliminarily designated write-permitted area. CONSTITUTION:An instruction is taken out from a memory 20 by an instruction taking-out circuit 25 and is set to an instruction holding circuit 21. The set instruction is supplied to a write instruction circuit 22. When it is detected that this instruction is a write instruction, this instruction is outputted to an area judging circuit 26 together with the write address. On the other hand, a write-permitted area is stored in a memory 24 when it is set by a write- permitted area setting circuit 23. The area judging circuit 26 receives the write instruction from the write instruction detecting circuit 22 and decides the write address range of this instruction. The address range is outputted to the instruction taking-out circuit 25 when it is within the permitted area, but an abnormality reporting circuit 27 is started when it is on the outside of the area.

Title: Digital low harmonic down converter
Inventor: CHIYAARUZU MAKUDONARUDO PUKETS
IPC: H04L27/14
Filed: 1990-03-27
Abstract: PURPOSE: To require only inexpensive ADC which is low in sampling frequency by converting an intermediate (IF) signal to a base band for afterward demodulation, setting (n) to an integer which is larger than 0, and using a sam pling signal which has a speed 4/(2n+1) times as fast as the IF frequency. CONSTITUTION: A complex digital sampling process consists of three different processes in which an input waveform is sampled at a sampling frequency which is four times as high as the frequency obtained by dividing a center frequency or carrier frequency by a divisor (2n+1), i.e., 4fIF/(2n+1), alternate couples of sampled signals are inverted and converted into the form of the base band, and a steam of data samples is divided correctly into components of an in-phase 1 and an orthogonal phase Q. Those three processes are carrier out by an ADC means 11, a digital mixer means 12, and an I/Q sorter means 18. Consequently, the need to use an expensive analog-to-digital converter(ADC) which increases sampling capability is eliminated.
