IPC: H05B37/02
Filed: 1977-12-30
Abstract: PURPOSE: To provide an apparatus for stepwise controlling brightness of a lamp, in which brightness of the lamp is changed stepwise by controlling a switching element to a certain conduction phase angle at the time when charging of a capacitor is completed, whereby switching from full-lighted mode to brightness-controlled mode can be effected instantly.  
     CONSTITUTION: Provided that changeover switch 5 is turned to the side of first contacts 6, 6a with wall switch 7 being kept in its ON-position, lamp 3 is fully lighted since it is connected to power source E via ballast B, first contact 6a of changeover switch 5 and wall switch 7. Simultaneously with this full lighting of lamp 3, relay Ry is energized momentarily via the circuit of power source E, the first contact 6a of changeover switch 5, capacitor 19, relay Ry, diode 20 and power source E, whereby relay contact (r) is closed momentarily and residual charge of capacitor 1 is discharged through resistance 9. When the switch 5 is turned to the side of a second contact 8, on the other hand, relay Ry is not energized and transistor Tr is kept in its OFF-condition since charging of capacitor 1 is completed.

Title: Multi-tubular heat exchanger
Inventor: OHASHI YUKIO
IPC: F28F13/12
Filed: 1985-07-22
Abstract: PURPOSE:To promote heat exchanging efficiency between a fluid inside a heat exchanger tube of a multi-tubular heat exchanger and a fluid flowing outside said heat exchanger tube to restrain pressure drop from becoming larger, by inserting a spiral plate in an axial direction of tube into a gap existing outside a heat exchanger tube within an outer shell. CONSTITUTION:The heat exchanger comprises tube plates 3 for securing heat exchanger tubes 2 thereto and a plurality of spiral plates 4 inserted in an axial direction of said heat exchanger tubes 2 into the space existing between the outside of a plurality of heat exchanger tubes 2 and the inside surface of a cylindrical shell 1. By the presence of the spiral plates 4 being inserted, rotational motion of fluid occurs, causing agitation therein, so that the temperature distribution of the fluid approaches to uniformized one, resulting in an abrupt change in the temperature of the fluid near the heat exchanger tubes 2, leading to a very large temperature gradient, heat flow per unit surface of the heat exchanger tubes 2 becoming large and surface resistance thereof becoming low. Furthermore, since reversion in the flow direction does not occur, increment in pressure loss can be limited to a small amount.

Title: Program execution state supervisory system
Inventor: TAKAGI HAJIME
IPC: G06F11/30
Filed: 1985-07-20
Abstract: PURPOSE:To detect the abnormality of execution state of a monitor program by reading a value written on a system table to compare it with a value read precedingly for decision. CONSTITUTION:The monitor program operated on an arithmetic processing unit 2 writes a present time of a clock 21 on an area 12-1 in a system table 12 at every reception of interruption. Thus, the time in the area 12-1 is updated at each reception of interruption. On the other hand, a diagnosing device 4 reads the content of the area 12-1 and stores it and then compares the present content with the preceding content. When the result of comparison is coincident, it is decided that the execution state of the monitor program is abnormal. Even when an inerruption reception number counter is provided in place of the clock, the similar effect is attained.

Filed: 1996-05-31
Abstract: PROBLEM TO BE SOLVED: To perform setting to a state equivalent to on-hook and to automatically open a line by detecting busy tone signals coming into an off-hooked telephone set and controlling a hook switching circuit. SOLUTION: A hook switch inside the hook switching circuit 1 is provided with a function for performing setting to an open state by control signals in addition to a normal function to be a closed state when a handset is detached. In the case of not practically being in a communication state, when the handset is detached, the busy tone signals are detected by a busy tone detection circuit 3. A microcomputer 4 receives the detected result, measures the lapse of fixed time after the detection of the busy tone signals is started by a built-in timer, operates the hook switching circuit 1 and disconnects a communication channel. Simultaneously, by lighting an LED or sounding a melody by an alarming means 5, the off-hook is alarmed. It is expected that a person around is alarmed and the handset is returned to an original position.

Abstract: PURPOSE:To stabilize the shape of a protuberance of a magnetic fluid and prevent a magnetic powder from precipitating after printing is stopped for a long period of time, by providing a magnetic fluid supplying means at a position such that the head from the tip of a multiple stylus to the liquid level of the magnetic fluid is set at a predetermined value suitable for supplying an appropriate amount of the magnetic fluid. CONSTITUTION:A magnet 2 for causing the magnetic fluid to form the protuberance is provided in the proximity of the tip of the multiple stylus 1 facing a recording surface 9, a fluid flow guide member 3 consisting of a magnet is additionally provided at a lower part of the magnet 2, and the means 7 for supplying the magnetic fluid to a part of the guide member 3 is provided. The supplying means 7 is provided between point A and point B which are in the range of head H0 ensuring that a suitable protuberance is formed. The amount of the magnetic fluid is so set that the amount of the fluid moved upwards by a magnetic force is balanced with the amount of the fluid tending to fall by gravity, resulting in that the fluid is adhered onto the stylus 1 as if the liquid level is disposed at the point of head H0. Accordingly, the shape of the protuberance is not changed even when the device as a whole is tilted. In addition, since little fluid is adhered onto the stylus 1 when the recorder is not operated, precipitation of the magnetic powder does not occur.
