Title: Casting device of molten metal
Inventor: YOSHIDA TSUTOMU
IPC: B22D11/07
Filed: 1981-03-25
Abstract: PURPOSE:To suppress heat transfer of a mold inside wall surface, and to prevent abrasion and deformation of the mold inside wall surface, by providing a lot of grooves in the casting direction on the mold inside wall surface of a continuous casing device, and forming a hardened surface layer on the mold inside wall surface provided with the grooves. CONSTITUTION:On the inside wall surface where a mold 10 contacts with a molten metal, a lot of grooves 11 are provided at a prescribed pitch as an inside wall longitudinal groove in the casting direction extending over its whole circumference, and on the mold 10 inside wall surface provided with the grooves 11, a prescribed hardened surface layer 9 is provided. Also, on the upper surface of the mold 10, a lubricating oil groove 12 is provided so as to be connected to the groove 11, and lubricating oil is supplied to the groove 11 from an oil reservoir 13. As a result, the molten metal supplied to the mold 10 contacts with a crest part 11a of the groove 11, and on the other hand, does not go into a root part 11b, and forms an air gap, therefore, the heat transfer can be suppressed effectively. Also, the surface of ingot is improved by supplying lubricating oil, and since the hardened surface layer 9 is formed, abrasion and deformation of the inside wall surface of the mold 10 provided with grooves are suppressed.

Title: Terminal multiple session control system
Inventor: OKUMURA KIMINOBU
IPC: G06F15/00
Filed: 1984-03-07
Abstract: PURPOSE:To cause an interruption for plural transactions to attain multiprocessing, and to utilize terminal resources effectively by disconnecting and reconnecting a terminal from and to an application and a user at optional points. CONSTITUTION:When the user makes a request to open a session at a terminal 6, a session control part 9 recognizes that by a terminal control function 91, creates a processing space for execution through a processing space creating function 93, etc., and passes the control to a user transaction processing part 10. Then, a terminal control function 103 is actuated to open the session to the terminal 6. Then, when the user operates an SPLIT key 62 after an RESET key 61, a session control key monitoring function 81 detects that and the transaction being processed is interrupted through the function 103, control part 9, etc., once an input/output request is made. Further, when an ROUND key 63 is operated, the interrupted session is restarted automatically. Consequently, an interruption is initiated for plural optional transactions and multiprocessing is performed to utilize terminal resources effectively.

Abstract: PURPOSE:To remove a mechanical contact section, and to make speed after damping constant easily by disposing a magnetic field generated from a permanent magnet, etc. to a predetermined section in a travelling stroke of a slider rectilinearly moving along a stator. CONSTITUTION:When prescribed AC currents are flowed through the coils 5 of the stator 7 and the slider 4 is made travel in the direction of the arrow B, the speed of the slider 4 is determined by the electromagnetic characteristics of the coils 5, coil current frequency, the weight of the slider 4, etc. until the left end 19 of the slider reaches a brake gear 10, induced voltage is generated among magnetic poles 14-17 and the slider 4 by the magnetic force of the permanent magnets 12, 13 after the left end of the slider rushes into the brake gear 10, and  the travelling speed of the slider is reduced. Since the induced electromotive  voltage (damping force) is proportioned approximately to the travelling speed of  the slider 4, approximately predetermined deceleration travelling is realized, and the starting of the slider 4 is hardly prevented when starting the slider 4 stopped by the brake gear 10.

Title: Method for controlling optical disk drive device
Inventor: TANIGUCHI ISAO
IPC: G11B7/085
Filed: 1989-02-23
Abstract: PURPOSE:To eliminate the degradation of a recording medium caused by light beam and to shorten a period from the start of optical disk rotation to arrival at a normal rotating speed by making the value of a light beam output smaller than that of an output at the time of recording or reproducing when the leading-in operation of focus control is started. CONSTITUTION:When the rotating speed of an optical disk is a rotating speed V1 lower than a normal rotating speed V0 at the time of the recording or reproducing of optical information, the output of the light beam is set to an output I1 smaller than a light beam output I0 to execute the recording or reproducing and the leading-in operation of focus servo is started. When the rotating speed of the optical disk reaches the V0 and the output of the light beam reaches the I0, the optical information are recorded or reproduced after the leading-in operation of the servo is completed. Accordingly, the influence of the light beam to be given to the recording medium can be reduced and the fixed area of the rotating speed needed for the execution of the leading-in operation is eliminated. Then, the period from the start of the optical disk rotation to the arrival at the normal rotating speed can be shortened.

Title: Radio communication system for train
Inventor: KATO TOMOKO
IPC: G08B26/00
Filed: 1991-01-08
Abstract: PURPOSE:To facilitate the transmission of emergency information from each train independently of polling during talking by adding a signal of one emergency system wave from a train to two-wave duplex radio signal of a talking system and using one control section to control the signal of three waves. CONSTITUTION:The control section 7a(7b) of a train radio equipment 2a(2b) discriminates a control signal such as a polling signal from a central equipment 1 to discriminate the propriety of the transmission from its-own radio equipment. When an emergent event takes place in the equipment 2a(2b), emergent information is sent from the control section 7a(7B) to the equipment 1 as an emergency system radio signal 22 via an emergency transmitter 20a(20b) and an antenna 21a(21b). The signal 22 enters the control section 7 via an antenna 19 and an emergency receiver 18. Since the frequency of occurrence of the signal 22 is very less in comparison with that of a talking system radio signal 9 and almost no crosstalk with other trains is caused, the signal 22 is optionally sent on the occurrence of a transmission request.
