Title: Copying device
Inventor: YOSHINAGA KENJI
IPC: G03G15/041
Filed: 1982-04-24
Abstract: PURPOSE:To execute copying which requires an exact position relation of a copying image, by providing an original scanning speed switching device for switching a scanning speed of an original scanning moving body in order to execute image variable power copying. CONSTITUTION:Immediately before a going motion of a light source 4 and mirrors 6, 7 is started by the first scanning speed, a pin 81 is detached from a cam 80, and gears 72, 73 rotate clockwise. When they rotate by a prescribed angle, a pin 79 is detached from a cam 78, and a drum 37 and a disk 76 start a rotation counterclockwise by an operation of a spring. When they rotate by a prescribed angle, the cam 78 is fitted to the pin 79 again. As a result, an original can be scanned at the first scanning speed. On the other hand, in a fitting device concerned in the second scanning speed, the pin 81 is fitted to the cam 80, and the original can be scanned again. In this way, since the position relation for fitting the pin and the cam is decided mechanically, the angle position of a photosensitive drum at the point of time when the going motion is started is fixed, and an area on the photosensitive drum 3 on which a picture is formed coincides at all times.

The servo-motor SM is rotated in reversed direction and the base cloth is transferred longitudinally in reverse direction while planting needles on the cloth. The planting operation is carried out based on information stored in a needle planting data memory.

Title: Power unit for air-conditioner
Inventor: YAMADA YUTAKA
IPC: H02P7/29
Filed: 1989-03-22
Abstract: PURPOSE:To reduce power loss and the overall size of power supply by outputting variable voltage following an external control voltage directly. CONSTITUTION:Self-excited oscillation frequency at the side of a primary winding 3 is modified based on comparison results between an output voltage from a rectifying/smoothing circuit 6 and an external control voltage and the magnitude of output voltage is varied. ln other words, magnitude of the output voltage varies according to the external control voltage. Since variation of output voltage from a power source S follows directly the variation of external control voltage, a circuit for varying the voltage independently is not required in addition to a switching power source producing a fixed output voltage.

Title: Film carrier tape
Inventor: SAITO MASAHARU
IPC: H01L21/60
Filed: 1987-03-26
Abstract: PURPOSE:To obtain a film carrier tape which is thermally resistant and whose size is changed little due to moisture and during a process using an alkali by a method wherein a film or a sheet is composed of a liquid-crystalline high polymer in the film or the sheet where a wiring circuit is formed by an etching process. CONSTITUTION:A liquid-crystalline high polymer refers to a thermo-tropic liquid-crystalline high polymer which displays liquid crystallinity during a heating process from a bulk state; a polyester-related liquid-crystal resin containing a p-phenylene ring is a representative example. After a film or a sheet of the liquid-crystalline high polymer has been slit to a prescribed width, one face is coated with a thermosetting adhesive; after that, a hole for a sprocket and a hole for a device are stamped; after that, a sheet of copper foil is attached and glued to the adhesive-coated face excluding the hole for the sprocket; a wiring circuit is formed by an etching process. Because, in a film carrier tape obtained in this way, a base film is composed of the liquid- crystalline high polymer, its contraction or extension during a circuit formation process is less than one-tenth that of a conventional film carrier taep.

Filed: 1989-03-24
Abstract: PURPOSE:To form a plurality of impurity layers in an identical process by a method wherein resist patterns are formed in individual impurity-introduction regions in such a way that ratios of exposed areas are different from each other. CONSTITUTION:When impurity layers are formed individually in a plurality of impurity-introduction regions RL, RM, RH on a semiconductor substrate 1, resist patterns 8 are formed in the individual impurity-introduction regions RL, RM, RH in such a way that ratios of exposed areas are different from each other. Accordingly, impurities of amounts corresponding to the ratios of the exposed areas are introduced into the individual impurity-introduction regions RL, RM, RH; a plurality of impurity layers whose introduction concentrations of the impurities are different can be formed in an identical process. Thereby, since the amounts of the impurities introduced into the individual impurity- introduction regions RL, RM, RH can be controlled, it is possible to form the plurality of impurity layers whose impurity amounts are different by one impurity-introduction operation.

Abstract: PURPOSE:To prevent a void from being produced in a thin resin-layer part for insulating use in a resin-sealed package by a method wherein a dummy cavity is situated on the side opposite to a gate of a main cavity and is arranged on the side into which a group of leads are inserted and a gate of the dummy cavity is opened over a whole width of the main cavity. CONSTITUTION:A dummy cavity 6 is arranged on one side of the side opposite to a gate 5 of a main cavity 3 and is formed so as to be nearly equal to a whole width of the main cavity 3. An end side adjacent to the main cavity 3 of the dummy cavity 6 is opened in such a way that a gate 7 is linked to the cavity 3. When a resin 8 is injected into the main cavity 3, the air inside the main cavity 3 is discharged to the outside through the dummy cavity 6; finally, a void 9 does not remain inside the main cavity 3. Thereby, it is possible to prevent the void 9 from being produced in a thin resin-layer part for insulating use in a resin-sealed package of a power transistor.
