Title: Time division communication method in mobile body communication
Inventor: ITO SADAO
IPC: H04B7/26
Filed: 1991-11-16
Abstract: PURPOSE:To reduce a repetitive zone number by using a same radio carrier so as to apply composite modulation to a telephone signal thereby sending/ receiving the resulting signal in the mobile body communication in which a time compressed signal is superimposed on a time slot of frame configuration. CONSTITUTION:A telephone signal is frequency-modulated by using one time slot of a radio channel allocated between a mobile radio equipment 100 and a radio base station 30 and the modulated signal is sent/received while the signal is amplitude-modulated again by using the same telephone signal. Since the carrier is frequency-modulated and then amplitude-modulated by using the same telephone signal, a large multiplex load gain is obtained and required transmission power is reduced, the interference to an adjacent radio zone is prevented in advance, the repetitive zone number is reduced to utilize the frequency effectively.

Filed: 1998-11-19
Abstract: PROBLEM TO BE SOLVED: To improve reliability in the quality of a controller for PACHINKO machine by improving the oxidation resistance of terminal of a connector. SOLUTION: By inserting a housing 32a of a line side connector 32 to a housing hole 30c of a device side connector 30, when holding the contact part of a male terminal 30b of the device side connector 30 between the forked contact parts of a female terminal 32b of the line side connector 32 through elastic operation while opening them to the outside, a contact surface 41 of the female terminal 32b is contacted to a contact surface 38 of the male terminal 30b. Since the contact surfaces 38 and 41 are made of oxidation resistant metals having a character hard to oxide at ordinary temperature and oxide coating is hardly generated at ordinary temperatures, trouble such as superimposing noises on a command in the style of small signal of small current and pulse width or omitting one part of command is dissolved and control processing corresponding to the command can be exactly executed.

Filed: 1989-12-19
Abstract: PURPOSE:To improve the reliability and the maintenance performance of programs by providing a means to re-edit a source program with use of the input information and a means to compile again the re-edited source program and to obtain a new object program. CONSTITUTION:In a compiling state, a statement having the possibility for occurrence of an error and its each corresponding break point are previously set to an object program 12. When an on-line debugging job is started, the execution of the program 12 is discontinued at a set break point and a request is produced for addition of error processing operations. In replay to this request, the due information is inputted and therefore the execution of the program 12 is restarted. As a result, the contents of the error processing to be added to each break point are sequentially designated. Hereafter a source program 10 is edited again and then compiled again based on the input information. Thus a new object program 28 including the error processing is produced. Then the reliability and the maintenance performance can be improved for programs.

At this time, the liquid diffuses fine air bubbles generated by the mixed gas laterally by the action of the baffle plate 17 provided to the bottom part of the impeller 11 and fine air bubbles are spread throughout the liquid to be dissolved in the liquid. The gap between a cylindrical body 20 and the drive shaft 12 is sealed by a bearing 19 and the liquid thereabove and the gas does not pass through this gap. Therefore, this apparatus is suitable as an apparatus dissolving gas harmful to a human body in the liquid.

Abstract: PURPOSE:To make a contact part perform self-cleaning by a method wherein the electrical contact part of a switch is shifted for every printing line by sliding a head holder. CONSTITUTION:An engaging part of a movable switch piece 21a is pressed down to a lower position of a tapered part 28a with the shift of a head holder 28. Thereafter, with the shift of the head holder 28 in a return direction, the movable switch piece 21a abuts on a fixed switch piece 22 at the position of an equilibium part 28b of the head holder 28. With the further shift of the head holder 28 in the return direction, the contact part of the movable switch part 21a with the fixed switch part 22 moves on a tapered part 22b of the fixed switch piece 22 by a restoring force of the movable switch piece 21a of a torsion spring 21. Therefore, the contact part moving at every restoring action of the head holder 28 performs a self-cleaning effect. Thus, even if foreign particles, such as dust and scum, are applied or invaded to the contact part, an electrically stable state is ensured.
