Title: Method of single-crystallization of semiconductor film
Inventor: YAMAGUCHI NORITOSHI
IPC: H01L21/20
Filed: 1990-03-30
Abstract: PURPOSE:To let heat escape by the application of energy beams not only in the in-plane direction of a semiconductor film but also in the thickness direction, to keep temperature distribution uniformly extending over the whole semiconductor film and to manufacture an excellent single crystalline film by applying an unsingle-crystalline semiconductor film under the state in which the semiconductor film crosses each of a plurality of metallic-film coating regions coating an insulating film. CONSTITUTION:Both metallic films 3a, 3b formed onto an insulating layer 1 as a substrate are coated with an insulating film 2. the insulating film 2 is coated with an unsingle crystalline semiconductor film 4 while crossing both metallic-film coating regions D1, D2, and the upper section of the semiconductor film 4 is coated with an insulating film 5. Beams L are applied and scanned in the direction of the arrow S from one metallic-film coating region D1 to the other metallic-film coating region D2 in order to change the semiconductor film 4 into a single crystal. Even when beams L are positioned at both ends of the semiconductor film 4, heat escapes not only in the in-plane direction of the semiconductor film 4 but also in the thickness direction to both metallic coating region D1, D2. Accordingly, temperature distribution in the semiconductor film 4 is equalized, thus obtaining an excellent single crystalline film.

Title: Heating controller
Inventor: YASUI SHIGEAKI
IPC: F24H3/04
Filed: 1989-04-05
Abstract: PURPOSE:To approximate the temperature of items to be heated to a set temperature even when the calorific load is different, by correcting the heating amount of a heating device corresponding to the difference between the set temperature and the measured temperature of the items to be heated at specified intervals that are counted by a timer. CONSTITUTION:A temperature difference controller 44 is a functional part that determines a base current value Ibase for a proportional valve 35 according to the temperature difference between the room temperature T( deg.C) measured by a room temperature sensor 43 and a set temperature T0( deg.C) set by a room temperature controller 42. A timer 45 starts counting time when room temperature T satisfies the formula, T0 - 2 <= T <= T0 + 2, and transmits time signals at specified intervals t (t = 164sec, for example) to a correction controller 46. An adder 47 is a part that adds a minus corrective current value DELTAIa or plus corrective current value DELTAIb, that is output from the correction controller 46, to the base current value Ibase determined by the temperature difference controller 44. The adder accumulates the minus and plus corrective current values DELTAIa and DELTAIb every time the time signals are transmitted from the timer 45.

Abstract: PURPOSE:To make up for a positioning accuracy of an accessor mechanism, also to reduce a containing pitch of a disk, and to improve a mounting efficiency by setting a V-shaped arm so as to be drivable to a picker of a library type collective type optical disk device. CONSTITUTION:First of all, an accessor mechanism 30 is roughly positioned at a position in the X direction in which an accessor 3 extracts or contains an object caddie by a servo-system, and also when it is positioned at the upper stage or the lower stage of a containing shed, arms 6, 6a move to the containing shed side by a rotation of a motor 12, and the V-shaped tip is inserted easily into a gap of a caddie groove. In case when a resistance is felt at the time of its advance, a frame 11 moves to a picker frame 4 against a spring force of springs 14, 14a so that the arms 6, 6a can advance, and so as to match the V-shaped inclined surface. At that time point, picker arms 7, 7a come to a position where the object caddie can be grasped, or a position where the grasped disk can be inserted into the object groove. In this way, even if an initial set position of the accessor is shifted a little, the caddie can be extracted and returned in.

Title: Carrier particle for electrostatic image developer
Inventor: NOMURA YOSHIHIRO
IPC: G03G9/107
Filed: 1978-07-19
Abstract: PURPOSE: To increase adhesive strength to resin covering, reduce residual magnetization, improve image quality and prolong developer life by oxidizing surfaces through heat treatment of iron cores used for carrier particles.  
     CONSTITUTION: Iron powder is heat-treated at 500 to 650°C in an electric furnace, whereby it is oxidized to e.g., surface oxygen amounts 0.35 to 0.50wt%. Then, the iron powder of magnetic permeability around 26 to 31emu/g, residual magnetization 5emu/g is obtained. Suspending this iron powder in air and spraying a solution of acrylic resins or the like followed by drying yield the carrier particles having been resin-coated. Toner is mixed in this carrier to prepare the developer. The high magnetic permeability increases the adhesion to a developing sleeve and prevents the deposition of the carrier on a photoreceptor and the low residual magnetization prevents deterioration of image quality with time such as decrease in resolving power or other. This results in prolonged developer life and better image quality.

Title: Cutting tool for plastic tube
Inventor: NAKASHIBA AKIO
IPC: B23B5/16
Filed: 1989-04-05
Abstract: PURPOSE:To enable a tube to be cut, without remaining part to be cut, on its outer peripheral surface by a fixed depth of cut after rectifying the deformation of the tube if any, by forming a cutting tool comprising a core being forcibly inserted into a tube, a main body fitted over the end of the tube, and a cutter fixed to the main body and having a length of blade longer than a necessary cutting length. CONSTITUTION:For cutting, a core 5 is disassembled from a main body 4 and is forcibly inserted into a plastic tube 13, then the main body 4 is pushed coaxially with the core 5 along the plastic tube 13 until it abuts to the end thereof so that it is fitted rotatably onto the core 5 or the main body with the core 5 fitted as it is pushed along the plastic tube 13 until it abuts to the end face thereof. Accordingly the blade edge 8a of a cutter 8 cuts in the outer peripheral surface of the plastic tube 13 and a cutter 9 cuts in the end face of the tube. Next the outer peripheral surface of the tube is cut with the cutter 8, and the end face of the tube is cut with the cutter 9 respectively, by one rotation with the main body gripped, thereby it becomes possible to cut the outer peripheral surface of the tube by a length of L from the end face thereof and by a fixed amount of cut.

Title: Optical mouse
Inventor: MIZUNO SEINOSUKE
IPC: G06F3/039
Filed: 1986-04-16
Abstract: PURPOSE:To easily form a line pattern, and also, to prevent a selecting range of a material of a pad from being limited, by providing the first line pattern of narrow width and the second line pattern of broad width, on the same surface of the pad. CONSTITUTION:The first line pattern 2 of narrow width is read by an image forming lens 4 being the first high resolution detecting optical element. An image forming lens 5 being the second low resolution detecting optical element cannot detect a contrast of the first line pattern 2, but detects only the second line pattern 3 of broad width. Accordingly, by forming the first and the second line patterns 2, 3 in the X and Y directions, positions in the X and Y directions can be detected from outputs of the first and the second detecting optical elements 4, 5. In this way, since only one face of a pad is used, the line pattern can be easily formed. Also, the pad is not limited to a transparent material, therefore, a selecting range of a material of the pad is not limited.

Abstract: PURPOSE:To correct the value of data in a CPU corresponding to a CPU output signal with the same voltage as an analog central voltage and to perform a stable control by comparing the central voltage of an analog control circuit and the output signal of the CPU. CONSTITUTION:At the time of applying a power source, by varying the CPU output signal 11 from a lower limit bound to a upper limit bound or from the upper limit bound to the lower limit bound, the output signal 13 of a comparator 12 is monitored. Then, in passing the point where the analog central voltage 10 and the CPU output signal 11 coincide, as the code of the output signal 13 of the comparator 12 varies, the digital value in the CPU corresponding to the CPU output signal 11 at that time is determined as the central value of the CPU. Thus, at the time of applying a power source, the central value in the CPU corresponding to the analog central voltage 10 is corrected by the CPU, and a stable control is attained.

Abstract: PURPOSE:To remove toner precisely from the surface of an image carrier by changing the rotating direction of a developing means in accordance with the moving direction of the image carrier. CONSTITUTION:A toner developing device 14 is provided with a magnet roller 16 in its inside and a hollow sleeve 15 dipped into toner D stored in a developing device box. At the formation of a picture, i.e. at the forward movement of a photosensitive body A, the roller 16 is rotated by a developing motor in the counterclockwise direction. Consequently, the toner D is moved on the surface of the sleeve 15 in the clockwise direction and carried to the photosensitive body A to execute development. At the time of cleaning, i.e. at the backward movement of the photosensitive body A, the roller 16 is rotated by the developing motor in the clockwise direction at a speed slower than that of the development. Consequently, the toner D is moved on the surface of the sleeve 15 in the counterclockwise direction to execute cleaning. Thus, the toner on the image carrier can be precisely removed.
