Filed: 1989-08-25
Abstract: PURPOSE:To make it possible to detect intrusion of water into oil chamber sensitively and stably by providing a water passing container through which only the water that has intruded into the oil chamber is made to pass, and filling the inside of the water passing container with water absorbing swelling material. CONSTITUTION:A motor 6 is driven, and an impeller 7 is rotated through a rotary shaft 8. Then, water is sucked up along the direction of an arrow in a pump 1. At this time, the water intrudes into an oil chamber 11 when there is function deterioration in a sealing device 10. The intruded water passes a water passing container 14 and intrudes into the inside. Pressure difference is generated between the two chambers in the container 14 which is separated with a gage plate 16. The gage plate 16 is elastically deformed by the pressure difference so that the restoring force is balanced with the water separating limiting force. Or the force which deforms the gage plate 16 overcomes the restoring force, and the gate plate 16 undergoes plastic deformation. A gage 17 is also deformed together with the deformation of the gate plate 16. Thus, the intrusion of the water into the oil chamber 11 is detected with a strain gate 17.

IPC: H01L29/792
Filed: 1992-08-17
Abstract: PURPOSE:To facilitate the film-thickness control and shorten the time of formation of an insulation film by performing the first oxyinitrization of an oxide film at the same temperature as the heating temperature of a base at formation of an oxide film, and performing the second oxynitrization at a temperature which maintains the introduction of nitric element into an oxynitride film in the middle of formation without increasing the thickness of the oxynitride film. CONSTITUTION:An SiO2 film 60 is grown on an Si substrate 18. In this case, it is to be desired that the speed of the temperature rise of the Si substrate 18 should be performed at 100 deg.C/sec, and that the peak temperature in heating should be 100-200 deg.C. Next, an oxide film 60 is changed into a nitride film by performing oxynitrization. For that, the oxynitrization is performed separately in two stages, and the first oxynitrization is performed at the same temperature T1 as the heating temperature of the base at formation of an oxide film, subsequently second oxynitrization is performed at the temperature T2 which maintains the introduction of nitric atoms into the oxynitride film during formation without increasing the thickness of the oxynitride film. Hereby, the processing time to grow an insulating film can be shortened.

Filed: 1998-07-31
Abstract: PROBLEM TO BE SOLVED: To provide a portable terminal device which accurately notifies its user of the urgent continuous incoming calls and enables the user to give the incoming answer calls by changing the incoming notification when the count value of a timer that is counted when the same originating IDs are received within a fixed time of the timer reaches its prescribed value. SOLUTION: If a continuous incoming detection timer 25A1, for example, is kept in its starting mode when an originating ID is received, it's decided whether the incoming calls sent from the same originator exceed its prescribed frequency while the timer 25A1 is kept in its starting mode. If the incoming calls received from the same originator exceeds its prescribed frequency, every continuous incoming detection counter 25A corresponding to the originating ID is stopped and a continuous incoming detection counter 25D is reset to perform the special incoming processing. A CPU 17 displays an incoming lamp 20 like in a normal incoming mode and also controls the gain of an amplifier 23 to increase the incoming sound volume of a buzzer 22 compared in a normal state.  As a result, a user of an incoming portable terminal device 1 notices the originating ID and can easily give its incoming answer.

Abstract: PURPOSE:To increase the number of messages to be controlled drastically, and to complete the contents of the message as well by operating asynchronously with the display operation of a display screen, reading out the stored history message from a printing memory and printing out it. CONSTITUTION:Display processing parts 3 and 4 have a display memory for storing the history message read out by a display request and a printing memory for storing the history message which a printing request is outputted to among the displayed history messages.
