Abstract: A video signal recording apparatus equipped with circuits to record a time code signal and a control signal relative to a tape position at a speed higher than a normal recording speed, whereby the time required for recording such signals can be widely shortened to reduce the time of the editing operation, hence enhancing the operational efficiency. Furthermore, the frequency of a bias signal is set to be higher than recordable signal frequencies determined in accordance with the normal tape speed, so that undesired generation of noise that may otherwise be derived from such bias signal can be prevented during the reproduction.

Abstract: A thermal stencil master sheet for stencil printing has a thermoplastic synthetic resin film which is perforatable with heat and a porous substrate, which is substantially unchanged by the heat. The film is bonded to the substrate with a urethane adhesive, preferably composed mainly of a specific urethane prepolymer obtained by reacting a polyether diol with a diisocyanate so as to give an equivalent ratio of NCO/OH of at least 1.1.

Abstract: Two thin plate members preferably made of metallic sheets are prepared and one end surface of at least one of the members is formed so as to have an inwardly curved recess which constitutes a gap when the end surfaces of the members are linearly butted together. A laser beam is irradiated along the butted portion of the members. The gap may have various forms having a predetermined width. The two members to be butt-welded may be substituted by two end portions of a single metallic sheet having a rectangular configuration in the case where a shell portion of a can is formed by the butt-welding operation.

Abstract: A semiconductor integrated circuit device includes a semiconductor nonvolatile memory, a booster circuit which generates a high voltage required for writing the data into said semiconductor nonvolatile memory, and a control circuit. With the thus constructed device, however, various external control signals often fail to assume definite levels when the power source is closed. If an operation mode to be designated is erroneously determined to be a write operation mode due to obscure levels of the external control signals, then the write operation is executed erroneously. To prevent such an eronneous operation from developing when the power source is closed, provision is made of a power souce closure detector circuit and a suitable gate circuit. Owing to these circuits, the output of the booster circuit is prevented from being applied to the memory element from the time from when the power source circuit is closed up to the time when the read operation mode is designated by an external control signal.

Abstract: A slit exposure type illuminating device mainly applicable to a color electrophotographic copier and using a plurality of lamps includes a single reflector which is provided with a plurality of openings for inserting the lamps. The lamps are arranged in an array along the length of the reflector. One of the lamps is positioned on an optical axis which extends through the center of the reflector with respect to the lengthwise direction of the reflector. The lamps are divided into a first and a second lamp groups in each of which they are arranged symmetrically with respect to the optical axis and individually spaced by predetermined distances from the optical axis. Current is fed either independently or simultaneously to the two different lamp groups. The openings of the reflector are each so adjustable in position and dimension as to prevent the bulb of each lamp from intercepting light.
