Title: Control circuit of tape recorder
Inventor: SAKAMOTO NORIYUKI
IPC: G11B15/02
Filed: 1980-08-22
Abstract: PURPOSE:To eject a cassette securely even in the high-speed running mode, by providing the 1st and 2nd pulse generating means driving a plunger for mode transition when a main switch is in the off state and after a prescribed time. CONSTITUTION:When an engine switch S1 is turned on and a cassette-loading responding switch S3 is also turned on, transistors (TR) Q2, Q4, Q3, and Q5 are turned off and when a stop/ejection switch S2 is operated manually at this time, TRs Q6 and Q7 turn on to drive a plunger 2. On the other hand, when the engine key switch S1 is turned off, the plunger 2 is driven as well and if a tape is in fast run mode, a playback mode is set. At this tie, the switch S3 keeps itself in an on state, so the TRs Q2 and Q4 are on to charge a capacitor C1 through a resistance R8; and the TRs Q3 and Q5, and Q6 and Q7 turn on to drive the plunger 2 again. Consequently, a cassette is ejected even in the playback mode.

Title: Method of preventing occurrence of trip due to high vibration of turbine shaft
Inventor: YAMAMOTO MASAKI
IPC: F01D21/14
Filed: 1984-06-08
Abstract: PURPOSE:To prevent a whole plant from being brought into a stop during earthquake, by a method wherein the turbine shafts of plural power plants in the same generating station are set in a direction different from each other. CONSTITUTION:In case 2 power plants are constructed in the same power plant, the direction of the turbine shaft of the other power plant (b) is turned in a 90 deg. arc from the direction of the turbine shaft of the one plant (a) to vary direction of the one turbine shaft from that of the other turbine shaft. Since vibration of a turbine shaft is generated by a horizontal and a vertical component, when the magnitude of vibration of the shaft is below a set value, a whole plant is inhibited against a stop. This enables prevention of the occurrence of unnecessary stop of a whole plant during earthquake.

Abstract: PURPOSE: To prevent wrong operation due to the temperature rise of heating  machine on a flying body, by injecting a coolant into a container containing the  heating machine and by installing a valve which is opned when the pressure in the  container rises.  
     CONSTITUTION: The coolant 6 such as flon R-22, which does not affect the heating  electronic machine 3, is injected into the container 5 containing the machine 3. The  valve 7 is attached to the valve 7. Launching the flying body, the temperature of  the heating electronic machine 3 rises. However,the heat peoduced is all absorbed  by the evaporation of the coolant 6. The temperature of the machine 3 does not rise  up to the boiling point until the coolant 6 is all evaporated. The pressure-increased  evaporated coolant goes out of the container 5 through a passage hole 11. Therefore, the heating electronic machine limited of temperature rise is effectively protected in the case of short time rating

Filed: 1988-05-14
Abstract: PURPOSE:To form the pressure page to a compact structure and to facilitate a piping operation by measuring a fluid pressure by the degree at which the elastic body disposed in a casing is brought into contact with the inside wall of the casing by the fluid pressure. CONSTITUTION:The elastic body 16 is formed of a stock such as rubber or synthetic resin having prescribed elasticity and is grasped and supported by the top end edge of a sleeve and a cap 14. The elastic body 16 is extended flat under no load but said body comes into contact with a tapered surface 14a when load is exerted thereto. The contact area increases on increasing of the pressure and, therefore, the pressure can be measured from the contact area of the elastic body 16 and the tapered surface 14a. Viewing of the contact part through the cap 14 from the outside is possible if the cap is formed of a transparent material. The pressure is known when the scale corresponding to the prescribed pressure is indicated. The formation of the pressure gage to the compact structure is thereby enabled and the piping operation is facilitated.
