Title: Relay line controller
Inventor: MIYAMOTO NAOYUKI
IPC: H04M3/42
Filed: 1987-09-18
Abstract: PURPOSE:To improve the activity efficiency of a line and to reduce the disconnection of the line current in use as far as possible by permitting the usage of the line for which time designation is closed with time limitation. CONSTITUTION:The closed state of a relay line 5 desired to use is generated by designating a time by an input/output console 4, and simultaneously, the designated time is stored in a timer memory 3. When a speech request for the relay line 5 whose time designation is closed is issued from a terminal 6 until the designated time, a PBX1 informs information with respect to the designated time from the timer memory 3 to the terminal 6 by a voice generator 2, and afterwards, connects the terminal 6 to the line 5 whose time designation is closed. In such a way, it follows that a terminal side performs a call by consent that the line is disconnected at the designated time, thereby, the activity ratio of the line can be improved even when the large number of lines to be captured in advance is required, and also, it is possible to prevent the line on the way of the call from being disconnected as far as possible.

Title: Non-contact system information card
Inventor: AMANO SHIRO
IPC: G11B7/24012
Filed: 1987-09-18
Abstract: PURPOSE:To execute the action of a long time by a built-in battery by adopting an element whose deflection angle changes when a voltage is impressed and controlling the reflectance of a reflecting part by a reflectance control part. CONSTITUTION:A reading device main body 31 is provided with a light emitting part 28 to emit infrared rays, etc., and a light receiving part 29 to receive the infrared rays. Projecting light from this reading device 31 is guided to a reflecting part 11 and the reflectance of the reflecting part 11 changes in accordance with transmitting data by the reflectance control part. Since the element whose deflection angle changes when the voltage is impressed is used for the reflecting part 11, electric power necessary for generating the change of this reflectance is slight and since the reflectance changes, the intensity of reflected light from the reflecting part 11 also changes in accordance with the transmitting data. Therefore, the reading device 31 to which this reflected light is guided reads the transmitting data from the change of the intensity of the reflected light. Thus, the action of a long time can be executed by the built-in battery.

Inventor: TACHIBANA TERUO
IPC: B29C45/62
Filed: 1995-09-14
Abstract: PROBLEM TO BE SOLVED: To change a material without generating a retention of a resin and make a supplying quantity of resin constant by comparing a motor load signal of an injection screw in conveying the resin with a set value, changing a tilt of a tilting rotary plate based on the result, and adjusting a depth of a notch groove. SOLUTION: A quantity of resin to be conveyed by a screw 2 is detected at a motor load detecting section 17 as a load signal of a motor 5 connected to the screw 2 and compared with a set value which is set at first by a control computation section 18. When a detected value of a motor load is larger than the set value, a conveying quantity of resin is larger than a desired quantity of resin, so that an output signal is sent to a groove depth adjusting cylinder 15 from the control computation section 18 through an output section 19 so as to make a tilting rotation angle of a tilting rotary plate 22 small, and a piston rod 15a is extended. To the contrary, when the detected value of the motor load is smaller than the set value, the piston rod 15a is retracted. As a result, the conveying quantity of resin is stabilized.

Title: Switching power supply
Inventor: HIGUCHI YOSHIO
IPC: H02M3/335
Filed: 1996-09-06
Abstract: PROBLEM TO BE SOLVED: To quicken the timing of detecting power interruption, by setting an error signal limit level when the input voltage of a switching circuit becomes lower than the voltage set in advance, and by generating a power interruption detection signal after the error signal has reached the limit level. SOLUTION: A switching circuit 13 switches a current flowing to the primary coil L1, and a control circuit 15 controls the switching operation of a switching circuit 13 based on an output current of a photocoupler 1. Also, a shunt regulator 2 detects a voltage error of an output 6, and this block outputs an error signal as the results of the detection. And if a power interruption occurs and the input voltage begins to drop, the voltage of the error signal 22 begins to rise greatly, a PNP transistor Q2 becomes OFF when the limit level occurs after the elapse of a certain time, and the power interruption detection signal 7 becomes an L level showing the power interruption. By doing this, the timing for detecting the power interruption can be quickened.
