Abstract: PURPOSE:To improve resistance to vibrations and a shock and to realize size reduction and full-electronic constitution by driving and holding plural analog switches which are connected to plural resistances, varying the composite resistance value of the resistances properly, and adjusting input/output relation. CONSTITUTION:Adjustment data A1 is written in a nonvolatile memory 44 when a write signal A2 is supplied, the signal A2 is stopped to fix the adjustment value written in the memory 44, and the value is maintained even in case of an afterward service interruption. Then ladder resistances 41a-41d are so constituted as to have resistance values r(OMEGA), 2r, 4r, and 8r and analog switches 42a-42d are put in opening/closing operation properly through buffer amplifiers 43a-43d by varying the adjustment value stored in the memory 44 to vary the composite value continuously from 0 to 15r, thereby adjusting the conversion of the frequency by a power frequency converting circuit 2 so as to obtain a prescribed frequency when all loads are inputted. Consequently, the input/output relation of the watthour meter is adjusted automatically, the vibration resistance and shock resistance are improved, and the device is reducible in size.

IPC: H05K7/20
Filed: 1988-08-12
Abstract: PURPOSE:To improve cooling efficiency and to improve the efficiency of a heat exchanger by a method wherein cold air and hot air are guided in a direction different from that of the intake air flow passages of a receiving part and a radiation part by means of an air guide or a radiation guide. CONSTITUTION:A cold air flow is guided by an air guide 6 and is fed to a position above an electronic device unit 5 being a substance to be cooled. Simultaneously, in order to take in air in a casing through a suction port 7 with the aid of a fan motor 31, cold air fed to a position above a casing 1 is sucked after the passage of it through a space in the vicinity of the electronic device unit 5 and the internal space thereof, and a cold air flow is circulated from above to below in the casing. The open air the temperature of which is increased resulting from contact with a radiation fin 42 through the blast motion of a radiation fan motor 41 is guided by a radiation guide 8 and discharged in an oblique downward direction outside the casing 1. Since the direction of the open air taken in through a suction port 43 is differed from that of the hot open air guided by the radiation guide 8 for discharge, two different kinds of the open air is prevented from direct mixture with each other.

Title: Cooling water sensor for marine engine
Inventor: IWATA SATORU
IPC: B63H21/38
Filed: 1994-08-26
Abstract: PURPOSE: To prevent the seizure of a marine engine due to the loss of cooling sea water by sounding an alarm when a cooling sea water flow rate drops to or below a minimum level required at the time of operating the engine at a maximum speed. CONSTITUTION: A float guide rod 3 is projected into a cooling sea water passage 5 and a float 1 is loosely fitted to the external surface of the lever 3, so as to be freely movable in a vertical direction. In this case, the float 1 stops at a position for the preset flowrate, due to a relationship between the rise of the level of cooling sea water from a lower level in the passage 5 and the weight of the float 1 itself. The position of the float 1 is electrically detected by use of a non-contact type sensor such as a hole element, thereby constituting a cooling sea water sensor. Also, a signal from the sensor is inputted and evaluated for the first time when the speed of a marine engine becomes equal to or above the preset value.  An alarm is turned on, when the signal of the cooling sea water sensor shows a level equal to or less than the minimum required flow rate of the cooling sea water.

Filed: 1988-08-15
Abstract: PURPOSE:To enable a secure operation to be carried out with a simple structure by constituting so that all the action required for a speed change gear such as the discharge and filling of pressure oil, and pressure modulation can be accomplished by a load piston in accordance with a prescribed schedule. CONSTITUTION:In the initial movement, a first and a second recessed grooves 46a, 46b are communicated, and while the pressure inside a signal pressure chamber 45 is released, a load piston 44 is moved to the extreme end to obtain the required minimum pressure. The fluid pressure from a pump 20 passes through a timing orifice 40j, and is filled into a filling chamber 49 for a prescribed time to move a changeover piston 48 to the closing position, and at that time the discharge from the signal pressure chamber 45 is shut off. Thereby the fluid pressure inside the signal pressure chamber 45 moves the load piston 44 to start pressure modulation, and passes through the first and second recessed grooves 46a, 46b. However, since the changeover piston 48 is in the closed position, fluid is not discharged. Accordingly, the pressure smoothly reaches the final pressure with a desired gradual pressure rise. In this position, the changeover piston 48 inside the load piston 44 is brought in the opened position for preparing the subsequent speed change.
