Title: Video camera
Inventor: KIMURA SUSUMU
IPC: G02B7/28
Filed: 1985-06-28
Abstract: PURPOSE:To improve connection between photographic scenes with simple constitution by adding a specific signal to a signal corresponding to distance information and defocusing images. CONSTITUTION:When a video camera is stopped during video recording, a signal for stop indication with fading effect is sent to a system controller 10 from a terminal 14, a slanting signal which rises in voltage to a constant value is supplied to one input terminal 16a of a comparator 16, and an electrical signal of a voltage corresponding to the quantity of infrared rays is supplied, so both signals are supplied from an input terminal 16a to the comparator 16. Consequently, a motor 18 is driven to rotate a focus adjusting ring 5 gradually to a position where an image is not in focus at all, thereby making a change from the video recording to a stop state. Thus, a defocusing state where the image becomes out of focus gradually is entered to obtain fading-out effect. Thus, connection between photographic scenes is improved.

Abstract: PURPOSE:To prevent cutting-apart of a shaped body and peeling-off from a base in the middle of shaping and make an irregular-shaped body shapable, in a method where a target shaped body is shaped by laminating curing layers in order by repeating a process in which the cured layer is formed on the base by applying a beam to the photosetting resin, the base is moved at a fixed pitch and after the cured layer is covered with the photosetting resin, the beam is applied to the same. CONSTITUTION:A precured layer 2 is shaped beforehand and a shaped body 1 is shaped. Shaping is performed by combining supporting bodies 3, 4 with each other between cured layers and between the cured layer and a base 21. The precured layer 2 and supporting bodies 3, 4 are removed after completion of the shaping. With this construction, a stuck area to the base 21 is secured by the precured layer 2 and peeling between the shaped body 1 and base 21 is prevented. An irregular-shaped part is supported stably by the supporting bodies 3, 4. Apparent sectional area becomes large by the supporting bodies 3, 4 and cutting-apart of the shaped body by ply separation between the cured layers is prevented.

Abstract: PURPOSE:To contrive an accurate and easy automatic unpacking of a paper pack ranging from the cutting to the spreading operation by a method wherein the paper pack is passed and carried over a square pillar body, its bottom lid is cut along its diagonals and the paper pack is sent out while being spread into the form of a flat surface. CONSTITUTION:The opening side of a paper pack 1 is moved in the direction of a square pillar body 2 and, when its opening part reaches the rollers 20a and 20b of a transfer mechanism, the paper pack is further moved in its transfer-out direction by the rotation of the rollers 20a and 20b. When the paper pack passes through a second cutter 17, the cutter 17 cuts open the one side of the paper pack body in the longitudinal direction. On the other hand, the bottom lid is retained by piercing a pin 14 through its nearly central part and a first cutter 13 cuts the bottom lid along its diagonals as the paper pack 1 moves. When the cut paper pack 1 is sent into the transfer mechanism, the transfer mechanism pinches, flattens and sends out the cut paper pack 1. Therefore, the paper pack unpacking can be accurately effected without requiring any manual work ranging from the cutting to the spreading operation.

Title: Method for measuring drawing resistance in mold for continuous casting
Inventor: TACHIBANA RINZOU
IPC: G01L5/00
Filed: 1980-10-14
Abstract: PURPOSE: To make the detection of ingot surface defects and breakout possible by measuring the acceleration waves or speed waves from a vertically moving mold, and measuring the drawing resistance in the mold from the indices obtained by subjecting these values to prescribed processing.  
     CONSTITUTION: While velocity waves or acceleration waves are measured from a vibrating mold, the velocity waves or acceleration waves of ≤2,500Hz are taken out from these measured values. The velocity waves and acceleration waves of the time when molten metal is not teemed are substracted respectively from these velocity waves or acceleration waves by time differentiation operation, and the operated acceleration waves and the previous acceleration waves are expressed by the function f(ω') of an angular velocity ω'. Further, the relative speeds shown by the differences between the mold vibrating speed and the ingot drawing speed of the function f(ω') are divided to a positive period and a negative period, and are time averaged by each period, whereby relative indices are determined. From these relative indices, the drawing resistance force in the mold is determined.

Abstract: PURPOSE:To reduce power consumption and to obtain a device suitable to a system by outputting the output voltage of a detecting circuit as a source voltage when the detecting circuit detects a gas leak, etc., and its output voltage exceeds a set value. CONSTITUTION:A detection part 1 is equipped with a gas sensor 11 and consists of the detecting circuit 13 which detects a gas leak at all times by using a DC power source 12 as a driving source and a source voltage output circuit 14 which compares the output voltage value of the circuit 13 with the set value and supplies the source voltage to a transmission part 2 when the voltage value exceeds the set value. Then when the circuit 13 is in a stand-by state the output value has a stationary value and the circuit 14 outputs no voltage. When the circuit 13 detects the gas leak and performs specific detecting operation, on the other hand, the output voltage of the circuit 13 varies. Its output voltage is compared with the set value by the circuit 14 and when it is confirmed that the output voltage does not vary merely and the detection operation is securely performed, the circuit 14 steps down and stabilizes the output voltage of the circuit 13 by a voltage stabilization part 15 to generate the source voltage, which is outputted to the transmission part 2, thereby performing various displays and control corresponding to the detecting operation.

Title: Prom protection circuit for erroneous insertion of prom vriter
Inventor: MIZUNO SAKUYUKI
IPC: G11C17/00
Filed: 1980-10-13
Abstract: PURPOSE:To prevent destruction when a PROM  writer is inserted reversely, by providing a circuit which detects whether a PROM is inserted into an IC socket normally or not and by varying an applied voltage on the basis of its detection  output. CONSTITUTION:When a PROM1 is inserted reversely into an IC socket, a voltage VINis applied to the PROM1 and a current flows through a resistance R4.  The current flowing through the resistance R4 becomes greater than that when it is inserted into the socket normally, so the plus terminal of a comparator 6 has a  lower level than that of the minus terminal, and the output of the comparator 6 goes down to a low level, so that an LED gives a warning by turning on. For the writing to or reading from the PROM1, a voltage application signal 10 is held at a high level only when an overcurrent detection signal 8 is at a high level. This signal is inverted by an inverter 9 to turn off a Q1, and an operating voltage Vout selected through resistances R1-R2 is applied to the power terminal of the PROM1.
