Title: Remote recording and reproducing control system
Inventor: FUKUDA TOYOJI
IPC: H04M1/64
Filed: 1984-12-21
Abstract: PURPOSE:To prevent the malfunction of the succeeding control of an automatic answering telephone set due to a remote control end signal by detecting the remote control end signal by a preliminarily determined short detection time to stop recording of the remote control end signal on a recording tape when the remote control end signal comes to the automatic answering telephone set and validating said signal by a preliminarily determined long detection time. CONSTITUTION:When the remote control signal such as a signal '#' is inputted from a subscriber line 12 for the purpose of stopping the recording operation during the progression of recording, this signal is transmitted from the subscriber line 12 to a microcomputer 20 and is detected when, for example, 50ms detection time elapses, and driving of the tape 1 is stopped by recording tape driving means (27, 6, 4, 5a, and 5b). If the signal '#' is inputted from the subscriber line 12 at a time t2 during recording, a PB signal receiver 33 outputs a DC output which rises at a time t2 after a delay time T3 of rise, and the CPU20 detects coming of the signal '#' at a time t3 after a monitor time T5, and driving of the tape 1 is stopped at the time t1 by recording tape driving means (27, 6, 4, 5a, and 5b). By this operation, the signal '#'of a time length T2 is recorded on the recording tape 1.

Title: Method for purifying sea water
Inventor: FUKUNAGA JUNJI
IPC: C02F3/32
Filed: 1989-10-16
Abstract: PURPOSE:To eliminate operations for removal of marine plants and to obtain at the same time by-products of sea water purification by growing marine plants using nutritive substances in sea water to remove nutritive substances for purification of sea water and by culturing edible marine animals using said marine plants as baits. CONSTITUTION:Sea water contaminated with eutrophicated salts is fed into a filtering tank 2 via a feed pipe 1 to remove impurities and said sea water is caused to flow down over the side of the tank 2 from the upper side thereof so as to be aerated. The aerated sea water is passed through a partition net 3, a purification channel 4 and then through a partition net 5 on the downstream side and is discharged to the sea from a discharge pipe 8. Sea weeds 6, as marine plants, are grown in the channel 4 and at the same time edible marine animals 7 represented by such shellfishes as ear-shells, sea-urchins and top shells which live on the sea weeds 6 are cultured therein. Since the sea weeds 6 absorb nutritive salts of nitrogen, phosphorus, etc., which contaminate sea water, to grow up, nutritive salts in the sea water decreases and the sea water is purified. The grown sea weeds 6 is used as food for the edible marine animals 7, whereby the animals 7 are cultured.

Title: Semiconductor device and its manufacture
Inventor: TOGO MITSUHIRO
IPC: H01L21/265
Filed: 1997-10-01
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device, in which a field effect transistor with trench separation has a gate-insulating film improved in dielectric strength at the end of its gate electrode and a method for manufacturing the semiconductor device. SOLUTION: The thickness of a gate-insulating film 4 is made equal to or larger than that of the central part of the film 4 by implanting ions of argon, etc., which increase the oxidizing speed of a silicon substrate 3 into the substrate 3 near a trench separating end or thermally oxidizing the silicon substrate 3 after implanting nitrogen ions, which decreases the oxidizing speed of the substrate 3 into the substrate 3 except for the vicinity of the trench separating end. Consequently, the deterioration in the dielectric strength of the insulating film 4 due to the thickness of the insulating film 4 becoming thinner at the end of a gate electrode can be prevented.

Abstract: PURPOSE:To set up plural timers (the range of a table area) only with one timer by controlling a timer identifier(ID) by time-out real time and setting up the timer first arriving at the time-out state from the real time values. CONSTITUTION:A timer register request from a processing task A or B in a processing task group 3 is received by a timer control task 2. The task 2 registers the timer while referring real time from e.g. an operating system OS 1. When a time-out report is generated from the OS 1, the task 2 receives the report and starts a processing task C generating a start request. When the timer register request is generated from the group 3, a timer ID 6 is a value to be returned to the group 3 and used for the identification of a timer cancel and time-out time. A timer value 7 is the value of a requested timer. Time-out real time 8 is the time obtained by adding the timer value to the real time for the timer register request. A pretimer ID 9 goes to time-out state faster than the ID 6. A post timer ID 10 goes to time-out state later than the ID 6.

Filed: 1990-10-05
Abstract: PURPOSE:To completely perform centrifugal separation while maintaining the set temp. by reducing the r.p.m. of a rotor and maintaining this r.p.m. so that cooling capacity balances with loss generated by rotation of the rotor when this loss exceeds the cooling capacity of a cooling device. CONSTITUTION:A sample 2 is housed to the inside of a rotor 1 and rotated by a driving motor 3 in the space closed by a chamber 4 and a door 5. Heat is generated by pneumatic friction due to rotation of the rotor 1. Quantity of heat is discharged to the outside of the chamber 4 by both a cooling pipe 6 equipped to the outside of the chamber 4 and a cooling device 7. Herein when a user sets the temp. of the rotor 1 to a controlling device 9, the temp. of the air in the chamber 4 is measured by a temp. sensor 8. The temp. of a rotor 1 is calculated on the basis of the experimentally obtained relation of the rotor 1 and the air in the chamber 4. The controlling device 9 controls the cooling device 7. Thereby centrifugal separation is enabled at the temp. set by the user even in the environment wherein capacity of the cooling device is reduced.

Abstract: PURPOSE:To obtain the different torque characteristics by the transfer of the meshing of a cam equipped with a cam surface having different cam angle to the can surface having different cam angle by the deflection of an urging member by a thrust force. CONSTITUTION:The transmission torque is applied as resistance torque on a cam 97 by the tightening of the first frictional clutch 77. When the torque is small, a thrust force 113 is smaller than the urging power of a belleville spring 103, and the cam interval is kept at t1 by the urging power, and meshing is carried out on a cam surface 107 having a large cam angle. Accordingly, in the small torque range, each thrust force 111, 113 is generated, and the variation of the thrust force for the variation of the resistance torque is small, and the control for the second frictional clutch 63 is facilitated. When the torque is large, the belleville spring 103 deflects perfectly, and the cam interval spreads to t2, and meshing transfers to a cam surface 109, and each large thrust force 115, 117 is generated, and in this case, a large tightening force is obtained by the second frictional clutch 63.
