Title: Vaporizative-cooling type transformer
Inventor: TAMURA KIYOSHI
IPC: H01F27/18
Filed: 1981-12-11
Abstract: PURPOSE:To increase the cooling efficiency of a refrigerant for the titled transformer  by a method wherein a connection pipe which connects a container and a cooling device is provided, the vapor of the cooling liquid is sent to the cooling device from the  container, and the condensed cooling liquid is flown into the container from the cooling  device. CONSTITUTION:When a winding 1 and a core 2 are heated up with the start of operation of the transformer, the cooling liquid 7 which was pumped up by a pump 8 is  sprayed upon the core 2 and the winding 1 by a sprayer 10, and the core 2 and the  winding 1 are cooled by vaporization latent heat. A part of the vapour 7a of the cooling liquid 7 is liquefied and starts dropping, the remainder of the vapour is accumulated  in the lower part inside the container 3 in the form of vapour 7a. When the pressure  of the container goes up to the prescribed value, a switching valve 12 is controlled. Accordingly, the vapour 7a accumulated in the lower part of the container 3 flows in from  the connection pipe 6. Then, the vapour 7a is condensed in the cooling device 6, turned  into a cooling liquid, and fed back to the container 3 in the form of a cooling liquid passing through the connection pipe 6. Through these procedures, the vapour only is  sent into the cooling device, thereby enabling to increase the cooling efficiency of the  refrigerant.

Title: Timing detecting circuit
Inventor: TAKAHASHI MINORU
IPC: F02D45/00
Filed: 1982-11-16
Abstract: PURPOSE:To detect the timing when the level of the output signal of a rotational angle sensor falls and becomes equal to a prescribed level with high accuracy, by providing a level switching means for changing the level of a reference voltage for a prescribed period when the level of the output signal of a rotational angle sensor rises and becomes equal to the level of the reference voltage. CONSTITUTION:When an angle signal given from a crank angle sensor or the like is applied to a terminal 1, the angle signal is applied to one terminal of a voltage comparator 3 via an LPF2 and it is compared with a reference voltage (b). The level of the output signal (c) of the voltage comparator 3 is kept at 0 for a prescribed period T1 from the time t1. This causes triggering of a multi- vibrator 5, and the output signal (d) of the multi-vibrator 5 is kept at a level 1 for a prescribed period T from the time t1. Resultantly, a transistor Q is turned ON and the level of the reference voltage (b) is changed to a level L3 in the time period from the time t1 to t2. By detecting rise of a signal (e) obtained by passing the output signal (c) of the comparator 3 through a digital filter 6, it is enabled to detect the timing when the level of the angle signal falls and becomes equal to a level L1.

Abstract: PURPOSE:To simplify feedback control in reference to the position control of the Z axis direction of a probe and to accelerate an information processing speed, by processing information after making the intrasurface direction of a temporary recording medium and the scanning direction of the probe parallel. CONSTITUTION:The optional one (101 is set to be the one) among probe units 10n is scanned at an optional section on a recording medium 2 and the inclination of the recording medium 2 is corrected by using the reproducing signal of surface state obtained at this time so that the scanning direction (the direction of X-Y) of a probe electrode and the surface of the recording medium 2 become parallel.

Filed: 1993-08-13
Abstract: PURPOSE:To detect an optical signal of far infrared ray with high sensitivity by so composing a detector as to allow a current flowing to a detector to flow in a zigzag manner to raise an operating resistance. CONSTITUTION:A light receiving surface 1 is formed of mercury cadmium tellurium(MCT), and a current passage of the rectangular surface 1 is formed in a zigzag shape, thereby more increasing its operating resistance. A voltage is applied to electrodes 2, 3 to supply a bias current of a predetermined value to the surface 1. When the bias current is set the same, the resistance of the detector is increased thereby to increase an output of the detector. The output is increased and an undesired infrared ray generated from a wall is suppressed to increase a noise level due to fluctuation of an incident light larger than that due to an unnecessary light incident from a periphery of an apparatus and a noise level of a preamplifier, thereby detecting it with high sensitivity.

Title: Engine control device
Inventor: OGURO HIROKAZU
IPC: F02D45/00
Filed: 1997-07-28
Abstract: PROBLEM TO BE SOLVED: To accurately detect preignition right before ignition by an ignition plug. SOLUTION: A CPU 31 in an ECU 20 determines an electrical connection starting time and an ignition time corresponding to an ignition signal to an ignition coil 5 at every given crank angle occasioned by rotation of an engine 1. An ignition plug 2 is caused to effect ignition operation according to the determined electrical connection starting time and the ignition time and the presence of preignition occurring right before ignition is decided. The presence of the preignition is decided by an ion current signal. Further, the CPU 31 sets a preignition decision time based on a current latest ignition time through carbon fouling interruption in the vicinity of an energizing starting time. When an ignition time is updated after a preignition decision time is set, a preignition decision time is reset based on an ignition time after updating.  In this case, even when an ignition time is varied through rapid rotation fluctuation occasioned by acceleration and deceleration, the preignition decision time is properly set corresponding to variation of the ignition time.
