Title: Liquid cooling device for engine
Inventor: MATSUI MASAKI
IPC: F01P7/16
Filed: 1991-03-01
Abstract: PURPOSE:To increase a temperature rising speed of a combustion chamber in order to carry out the engine start in a short time at the time of starting the engine by interlocking/connecting a passage opening/closing valve, which is provided in a liquid extracting passage, to a valve driving device, and interlocking this valve driving device to an engine starting device so that the valve driving device opens the passage opening/closing valve. CONSTITUTION:A liquid extracting passage 6 is led out from the liquid cooling jacket 2 of a combustion chamber 1. A passage opening/closing valve 7, which is provided in this liquid extracting passage 6, interlocked/connected to a valve driving device 8. This valve driving device 8 is interlocked to an engine starting device 9. When this engine starting device 9 is operated for starting its work (10), the passage opening/closing valve 7 is opened by the valve driving device 8. Since the cooling liquid within the liquid cooling jacket 2 is extracted at the time of starting the engine, the heat of combustion, which is generated in the combustion chamber 1, is not radiated to the cooling liquid, but accumulated in the combustion chamber 1. With this contrivance, the temperature rising speed of the combustion chamber is increased, and the start of the engine can be carried out in a short time.

Title: Magnetic recording and reproducing device
Inventor: NAKANO KENJI
IPC: G11B5/02
Filed: 1989-03-14
Abstract: PURPOSE:To prevent a signal left unerased from being reproduced by judging a signal of a PCM area whether it is the recorded signal in relation with a video image or the signal left unerased irrelevant to the video image. CONSTITUTION:A PCM latter half area setting circuit 5 sets the latter half of a PCM area, detects an error number of a reproduced data at the area latter half and whether the PCM signal recorded in the PCM area is in relation to a video image or a signal left unerased irrelevant to the video image is judged from whether the error number is a prescribed value or over. When a new video image is recorded again on a tape with the PCM signal already recorded by using the 8-mm VCR whose PCM recording system is not set, the latter half in the PCM area is destroyed concentratingly. Thus, when the error of the reproduced data of the latter half of the PCM area is detected, even when the video area with re-recording is slightly overlapped with the PCM area, the PCM signal recorded in the PCM area is surely judged as to whether the signal is in relation with the video image or a signal left unerased.

Title: Order placing and receiving system utilizing telephone communication system and its automatic order receiving system
Inventor: AKIBA YOSHIKI
IPC: G06Q30/06
Filed: 1992-02-16
Abstract: PURPOSE:To facilitate a complicated commodity ordering job by employing an existing tele phone communication system so as to form an order receiving and placing network, connecting an automatic order receiving device to a telephone set of an order receiving side and employing an order placing terminal equipment to a telephone set of an order receiving side. CONSTITUTION:An order placing party A or B operates a button of a telephone set to convert ordering information into a push tone signal and to send the signal to a telephone set of an order receiving side. When the telephone set of the receiving side receives the signal, it is fed to a push tone signal discrimination means of the automatic order receiving device and decoded thereat, an information retrieval generating means generates a reply guidance, a voice conversion means converts the guidance into a voice signal by the rule synthesis method and the reply guidance in a voice signal is sent to the order placing side via the telephone set. The order placing party listens to the reply guidance for the confirmation and sends succeeding ordering information to the order receiving side by the pushbutton operation. The order receiving side writes the order receiving information to a prescribed file of a database and uses a CRT or a printer to output the data. Thus, the complicated commodity order placing and receiving job is facilitated and mistake in the transaction is reduced.

Title: Manufacture of semiconductor device
Inventor: KAWAKITA KENJI
IPC: H01L21/3205
Filed: 1987-03-17
Abstract: PURPOSE:To accurately taper-etch an insulating film with a thin organic film as a mask by directing inorganic element or inactive atom ions onto the surface of the film opened perpendicularly. CONSTITUTION:After inorganic element or inactive atom ions are directed onto a resist pattern 12 formed substantially perpendicularly on to its end, with a resist as a mask an insulating film 11 is perpendicularly etched to form a tapered opening of the film 11. Since the etching velocity on the surface of the resist irradiated with the ions becomes slow, even if oxygen gas or the like is added to accelerate the lateral velocity of the resist, perpendicular etching velocity can be suppressed. Thus, even if the resist has a perpendicular shape, the insulating film can be taper-etched without loss of the masking property of the resist, thereby realizing high dimensional accuracy and controllability.
