Title: Superconducting coil and prepreg semicured tape
Inventor: NUMATA SEIJI
IPC: C08L77/00
Filed: 1989-01-30
Abstract: PURPOSE:To prevent a cracking of an impregnated resin from being produced by a method wherein a fiberlike filler is mixed with a resin layer between coil conductors. CONSTITUTION:In a superconducting coil 1, a superconducting wire 2 constituted of an NbTi superconducting filament and of stabilized copper is wound in a racetrack shape, and a prepreg semicured tape 5 is wound in one turn at a half-hooked manner between individual layers and on the surface of the coil. This superconducting coil 1 is put in a molding metal mold; while it is being heated, it is molded by executing a three-dimensional pressurization operation. By this pressurization molding operation, a fiberlike filler 6 is extruded, from the prepreg semicured tape 5 wound between coil conductors and on the surface of the coil, between the coil conductors and on the surface of the coil in a state that it is mixed with an epoxy resin 7, and through thermosetting a resin layer 8 is formed. The prepreg semicured tape 5 uses a polyimide film 9 as a base material; both faces are coated with the glass-fiberlike filler 6 to which the epoxy resin 7 mixed with a hardening agent and a solvent has been added; this assembly is heated; the epoxy resin is matured; a resin layer 10 is formed. Thereby, it is possible to prevent a crack of the impregnated resin layer from being produced and to obtain the superconducting coil whose reliability is high and whose current density is high.

IPC: H01L27/04
Filed: 1982-02-08
Abstract: PURPOSE:To enable the security of operation margins and the high speed reading, by increasing the junction capacity of clamp diodes more than the capacity parasitic between the transistor collector and a substrate. CONSTITUTION:Resistors 3, diodes 4, and the impedance of CD and CS are related to the speed at which the signal of a word line (d) transmits to the collectors 1 and 2. To increase the junction capacity CD without increasing the area of the diode 4, a Schottky barrier diode is used wherein ions are implanted into the semiconductor side. The Schottky barrier diode is constituted of an Si contained Al electrode 6, an oxide film 7, and a high density N region 8 and a low density region 9 formed by an ion implantation. The N region 8 functions to decrease the threshold voltage of the Schottky barrier diode and increase the CD.

IPC: G11B27/00
Filed: 1999-01-27
Abstract: PROBLEM TO BE SOLVED: To store data of auxiliary information having a relatively large capacity without managing identification information for storage mediums by storing the auxiliary information of the main data on a recording medium taking a fixed-length pack shorter than a data block as an unit, and storing the auxiliary information so as to follow the respective main information. SOLUTION: A tape is moved by an index signal to a starting position at which auxiliary information is recorded. When this auxiliary information is older than the contents temporarily stored on a main body, an updating operation is then performed. In the case where a TV program or the like is to be recorded from the beginning of the tape, a region suitable for storing auxiliary information for the entire tape (TOC information) is secured, and thereafter auxiliary information of a program A is stored on auxiliary information storing means. Then, information of the program A is stored on the tape. After completion of writing, the regions including one for the auxiliary information of the program A secures a series of regions sufficient for storing the auxiliary information for the entire tape, and the procedure goes to a waiting condition for the next recording.

Filed: 1996-01-10
Abstract: PROBLEM TO BE SOLVED: To provide an output device outputting data without deteriorating the dignity of printing and the like even if memories which can be used are not sufficient. SOLUTION: If printing information is inputted in a page buffer when printing information expressed by a page description language is transmitted from a host computer 3000 through an interface 21, a printer control unit 1001 analyzes printing information stored in the page buffer, generates an intermediate code and preserves it in an intermediate code memory. When a space does not exist in the intermediate code memory and the intermediate code expressing a binary image exists in the intermediate code memory, a closed area is divided into the block of 4×4. The number of black picture elements existing in the closed area of 4×4 is counted and an obtained counted value is converted into a prescribed code and the intermediate code memory is cleared.  Printing can be executed without deteriorating printing dignity even if memories which can be used are not sufficient by analyzing the intermediate code and generating the printing image.

Title: Motor-driven variable resistor
Inventor: YOKOCHI SHIGERU
IPC: H01C10/14
Filed: 1990-01-29
Abstract: PURPOSE:To obtain a large reduction gear ratio in simple structure and reduce components materials and assembling cost by providing an internal gear mounted with an operation shaft and its opposite internal gear, planet gear and a gear engaged with said planet gear. CONSTITUTION:A friction gear 21 and a brush mounting board 19 are slight different from each other in the number of teeth, which produces rotating deviation. For example, when it is assumed that the tooth number of the friction gear is 100 while the tooth number of the brush mounting board is 101, one turn of the planet gear 23 will be deviated by one tooth, thereby providing the reduction of 1/100. If the tooth number of an opinion gear 29 is assumed to be 20, the rotation of the planet gear 23 will be reduced to 1/6 of the rotation of a motor shaft 26a, thereby obtaining a total reduction of 1/600. At the same time, friction gear 21 has enough heavy rotating torque with a motor mounting fitting 24. Therefore, it is possible to obtain favorable operation feeling, which makes it possible to provide large reduction in simple structure and reduce component materials and assembling cost as well.

Title: Resonant switching power supply
Inventor: YOKOTA HIDEKI
IPC: H05B41/34
Filed: 1992-01-08
Abstract: PURPOSE:To achieve resonance regardless of fluctuation of MC charging voltage by switching a charging circuit from parallel operation to series operation upon elapse of a predetermined time after discharge of a main capacitor(MC) and then charging the MC. CONSTITUTION:A timer circuit 57 begins to measure time at a point of time when a discharge detecting circuit 59 detects discharge of an MC14 and switches a switching element(SW) 55 through a switching circuit 58 upon elapse of a predetermined time. The switching circuit 58 produces a signal for turning the SW55 OFF so long as a charging voltage V0 is lower than about half of maximum voltage. Consequently, a charging circuit for the secondary winding(SC) 51, a diode bridge(DB) 52 and a diode(DD) 54 operates in parallel with a charging circuit for an SC51', a DB52', and a DD53 to charge the MC14. When the charging voltage V0 reaches about half of the maximum voltage, the switching circuit 58 produces a signal for turning the SW 55 ON. At that time, a transmission voltage is applied on the DDs 53, 54. In other words, two sets of rectifying circuits operate in series to charge the MC14.

Title: Thermal head preheater
Inventor: UENO KEIICHI
IPC: B41J2/38
Filed: 1982-02-12
Abstract: PURPOSE:To perform preheating within the capacity of power source necessary for drive by providing a preheating period setter in which preheating period to impose overload to an electric wire is regarded as a non-drive period for a thermal head for a facsimile, etc. CONSTITUTION:During the period when recording is made on 1st paper in the time periods t11-t12 and on 2nd paper in the time periods t13-t14, a signal 5 to selectively drive a thermal head 1 is outputted. On the other hand, when the temperature of the base plate of the head 1 is lowered beyond a given value, a temperature controller 14 sends out a preheating lowering detection signal 16 and also a print controller 11 sends forth a recording stop period signal 17 representing the period when the signal 5 is not outputted. A preheating controller 13 sends out a preheating start signal 18 on the basis of the AND of both signals and a preheating current 8 is flowed in the varister of the head 1 for the preheating period T. The current flows in too much amounts in the early period to lower the voltage V of the power source 4 but returns to its original state within the period T. Thus, better recording can be made by effectively utilizing the power source without the use of preheating power source.
