Title: Preparation of aliphatic chloroformate
Inventor: YAMAGUCHI TOYOHIKO
IPC: C07C68/02
Filed: 1981-05-26
Abstract: PURPOSE: To obtain the titled compound which is a raw material for preparing urethanes, carbonates, etc. safely and hygienically by easy operations, by reacting trichloromethyl formate with an aliphatic alcohol.  
     CONSTITUTION: Trichloromethyl formate is reacted with an aliphatic alcohol, e.g. methanol or ethanol, to give an aliphatic chloroformate. The reaction is carried out in an inert organic solvent, e.g. n-hexane in the presence of a compound containing nitrogen at -10W+40°C. A heterocyclic compound having one or two tertiary nitrogen atoms, e.g. pyridine or quinoline, or aliphatic tertiary amine, etc. may be cited as the catalyst. This method is a highly safe method due to no need of handling the toxic carbonyl chloride in the gaseous state. The resultant titled compound is also useful as a raw material for preparing agricultural chemicals, medicines and dyes.

Abstract: PURPOSE:To improve the extent of mu-wave absorbing efficiency by installing an exciting coil group on an outer circumference at the front end of a plasma generating chamber and also an auxiliary exciting coil on an outer circumference in the intermediate part, respectively. CONSTITUTION:A reactant gas is sealed in a plasma generating chamber 2, inducting a mu wave P, and direct currents are fed to a exciting coil 3 and an auxiliary exciting coil 10. The vicinity of an inlet port 5 turns to a high magnetic field through the coil group 3, so lowering along the incident direction. ECR plasma is produced in the chamber 2 at a position passed through an area where ECR conditions are satisfied, and a magnetic field once lowered from the ECR conditions is set down to the high magnetic field again by means of the auxiliary coil. At this time also, the ECR plasma is produced in a corresponding position passing through an inner part of the chamber 2. In consequence, the extent of the inducted mu wave is improved and, what is more, plasma density increases too.

Title: Sound field compensating device
Inventor: NAKAMURA KAZUHIRO
IPC: G10K15/00
Filed: 1991-04-11
Abstract: PURPOSE:To limit the band compensated with an adaptive FiR filter to a low band and to reproduce the natural sound by dividing into a low frequency area to compensate an input signal and a high frequency area not to compensate the signal by LPF and HPF. CONSTITUTION:Dividing of the input signal into the band to compensate an input signal and the band not to compensate the signal is performed with an LPF 21 and an HPF 34. A low band side only is compensated and the sampling frequency of an A/D converter is lowered. As this result, the arithmetic quantity of an adaptive FiR filter and the arithmetic quantity of the coefficient renewal are decreased. Since the high area is not compensated, the compensation error of the high area caused by the movement of the listening position can be eliminated and the natural feeling sound can be reproduced.

Title: Thermal reaction of solid raw material and apparatus therefor
Inventor: KEMIZAKI KAZUHIRO
IPC: C07B61/00
Filed: 1994-03-25
Abstract: PURPOSE:To prevent the abnormal local heating and carry out uniform heating in the microwave heating of a solid raw material to be subjected to chemical reaction. CONSTITUTION:A solid raw material is formed to almost spherical shape. The obtained spherical raw material 6 is transferred under rotation with a transfer apparatus 5 and irradiated with microwave with a microwave waveguide 4 during transfer. Since the solid raw material is formed to almost spherical shape, edges to concentrate the microwave energy are eliminated to prevent the abnormal heating caused by the microwave concentration. Furthermore, uniform microwave heating can be carried out by the rotation of the spherical raw material to prevent the concentration of microwave caused by temperature difference.

Title: Error correction device
Inventor: ABE TAKAO
IPC: H03M13/00
Filed: 1996-03-07
Abstract: PROBLEM TO BE SOLVED: To eliminate useless power consumption in an error correction device for decoding data error correction encoded by a product code. SOLUTION: The data supplied to an error correction decoder 9 constituted as one integrated circuit are supplied to an internal code decoder 23 and error corrected and the data are written to a RAM 30 through a controller 29. In the case that all errors are corrected in the decoder 23, since error correction by an external code decoder 31 is not required, the data are read from the RAM 30 and outputted to the outside. At the time, by the stoppage of clock supply or the like for instance, the operation of the decoder 31 is stopped. Since the decoders 23 and 31 are constituted as the same integrated circuit, the need of an interface between them is eliminated, and in the case that the error correction by an external code is not required, the operation of the decoder 31 is stopped. Thus, the useless power consumption is suppressed.

IPC: H01H43/02
Filed: 1986-04-07
Abstract: PURPOSE:To obtain an inexpensive device which allows a time display and a timer display to be easily recognized by providing 24 light emitting elements corresponding to 1-24hr and displaying the current time and a timer-on time by the blinking or illumination of the elements. CONSTITUTION:The twenty four light emitting elements 0-23 corresponding to 1-24hr are provided, the current time is displayed by the blinking of a corresponding light emitting (e.g. element 3,), and a display in a timer-on time zone is made by the illumination of a corresponding light emitting element group (e.g. elements 16-19). Further, at the time of the current time is within the timer-on time zone, a light emitting element (e.g. element 18) which displays the current time is so controlled as to blink in different mode. Consequently, the time display and timer display need not be made by different light emitting groups, so the number of the light emitting elements is decreased and the displays are easily recognized.

Title: Magnetic recording and reproducing device
Inventor: NAGAFUNE YUKIO
IPC: G11B15/02
Filed: 1987-03-31
Abstract: PURPOSE:To correctly know of an alarm time without using an another alarm clock by providing an alarm function on a timer faculty, sounding an alarm time by a sounding means and displaying it by a display means. CONSTITUTION:A timer/microcomputer 13 receives a command by pushing the alarm time setting switch 1d of a program setting switch device 1 to change a display means 17 in alarm display mode. The selection of the set modes of forenoon, afternoon and alarm time is then done by a setting transfer switch 1b and the time setting is done by a set switch 1c. At the alarm time it is displayed by the display means 17 and meanwhile an informative signal is transmitted from the timer/microcomputer 13. Since the informative signal drives a speaker 15 by being amplified by an amplifier 14, the alarm time can be known even with the sound of the speaker 15. An alarm time can thus be known without prepg. an alarm clock separately.

Title: Semiconductor integrated circuit
Inventor: YOSHIDA MASAAKI
IPC: H01L23/52
Filed: 1986-04-08
Abstract: PURPOSE:To cope with the deterioration in the life of wirings due to an electromigration without increasing the width of power source wirings even if a current increases due to miniaturization by increasing the thickness of power source wirings as compared with that of signal wirings to suppress the ratio of occupying the chip area of the power source wirings. CONSTITUTION:The thickness of power source wirings 4 is increased as compared with that of signal wirings 2, 3. In other words, the thickness of the power source wiring film in which a large current flows to readily cause an electromigration is increased to prevent the electromigration from occurring. Accordingly, the width of the power source wirings is not necessarily increased to suppress the area of the power source wirings occupied in the chip area to small value, thereby performing high integration due to miniaturization.
