Title: Programmable input circuit
Inventor: KAWANA KEIICHI
IPC: H03K19/0175
Filed: 1994-02-04
Abstract: PURPOSE:To provide the input circuit which programmably realizes a pull-up circuit, a terminating circuit, or the like adapted to an external circuit in an integrated circuit. CONSTITUTION:Plural resistance elements R1, R2, R3 and R4 capable of forming a pull-up circuit, a pull-down circuit, and a terminating circuit are preliminarily provided in the integrated circuit so that connection/non-connection of these elements can be programmably set through switch elements S1, S2, S3, and S4. Arbitrary one of the pull-up circuit, the pull-down circuit, and the terminating circuit is formed by programming of these switching elements to programmably realize an optimum input circuit in accordance with the external circuit. Thus, an external input circuit is omitted, and the mounting density is raised, and the number of parts is reduced, and a device is miniaturized, and the cost is reduced. The convenience that a user can assemble a circuit corresponding to an application at hand without changing the mounting or the like is improved.

Title: Rotary-position detecting apparatus
Inventor: YAGI KENJI
IPC: G01B7/30
Filed: 1991-01-09
Abstract: PURPOSE:To prevent the deviation of the position of a signal by increasing the rotary angle corresponding to the width of the opening part of a shutter in the rotating direction at a position which is separated further from the central position in the direction perpendicular to the rotating direction, and changing the width of the opening in this way. CONSTITUTION:In a rotary-position detecting apparatus, the opening part of a shutter 14 is formed in an angle shape so that the width of the opening part is linearly broadened when the position of the opening part is further separated from the central position in up and down directions at the regular position relationship with respect to a detecting element 15. When the relative position of the shutter 14 with respect to the element 15 is deviated in the axial direction which is perpendicular to the rotating direction, the output voltage of the element 15 becomes the trapezoidal shape. The voltage is changed in the direction where the maximum output voltage and the inclination become small. At this time, the starting position of the rise-up of the output voltage of the element becomes faster than the regular time by the amount of the width of the opening of the shutter 14 which has become wider. The final position of the fall-down becomes later than the regular time. Therefore, the width of the output signal and the signal position of the rotary-position detecting apparatus are not changed with respect to the same threshold voltage as in the regular time.

Title: Medium storing printer driver program
Inventor: TOMIYASU KUNIO
IPC: G06F3/12
Filed: 1998-01-08
Abstract: PROBLEM TO BE SOLVED: To automatically judge the heavy load of printing of data and to permit a user to recognize whether data is correct or not so as to prevent wasteful printing. SOLUTION: An alarm control image is displayed before printing data is sent to connected printers 2a-2c by a computer device 1 with a printer driver program stored an a floppy disk 6. A user selects whether to adopt the alarm control of a print job. When the total number of printing sheets is selected as an alarm condition, the total number printing sheets on a print job is obtained, which is compared with a threshold number of sheets. When the total number of printing sheets is more than the threshold number of sheets, an alarm message is displayed and a system waits for the instruction of the user. When the user recognizing the alarm message instructs cancellation of the job, the present job is cancelled and the system starts a printing when the user instructs the continuation of the job.

Title: Grooved optical master disk
Inventor: OTSUKA YASUHIRO
IPC: G11B7/24
Filed: 1987-01-22
Abstract: PURPOSE:To attain the molding by the injection molding by using a ceramic substrate formed with a ceramic sputtering film for a sintered ceramic plate whose compression strength is specified respectively as a hard substrate so as to improve the mechanical strength. CONSTITUTION:Since an average pressure exerted to a grooved optical master disk with groove reaches several tens - several hundreds of kg/cm<2> in general at injection molding, the compression strength of at least 1,000kg/cm<2> or over is required for the grooved optical master disk. Thus, the sintered ceramic plate and the ceramic substrate of the sputter film of ceramic whose compression strength it at least 1,000kg/cm<2> are used as the hard base material. In such a case, the ceramic substrate covering the pin holes existing on the sintered ceramic plate by the sputtering film of ceramics is used as a hard substrate, then no pin hole exists and the grooved optical master disk sufficient in strength against the injection molding pressure is obtained.

Title: Superconducting magnet device
Inventor: WATANABE TETSUO
IPC: H01F6/00
Filed: 1990-01-25
Abstract: PURPOSE:To make a cooling operation efficient and to reduce the evaporation amount of cryogen by a method wherein a support material supporting a magnet is made hollow, an electric-current lead is passed through its inside and the support material and the electric-current lead are cooled simultaneously by sensible heat of the cryogen. CONSTITUTION:A superconducting magnet 1 is cooled inside a coil container 2 by using a cryogen 3 such as liquid helium or the like. The coil container 2 is housed inside a vacuum container 4 which has taken measures against creeping heat. A hollow support material 6 fixes the vacuum container 4 and the superconducting magnet 1 so as to arrange the superconducting magnet 1 in the cryogen 3. An electric-current lead 5 is passed through the inside of the hollow support body 6 and is connected electrically to the superconducting magnet from an opening part at the lower end of the support material. The cryogen which has crept from the opening part at the lower end of the support material is gasified. While it cools the support material 6 and the electriccurrent lead 5, it is moved to the side of the vacuum container at room temperature. It is discharged to the outside of a device. Consequently, since they are cooled by utilizing sensible heat (enthalpy difference) by which the cryogen is gasified and becomes a gas at room temperature, they can be cooled efficiently.

At the time of passing of the material through the said passage 70, shearing force and friction force are applied further to this material and heat is generated on the material. Therefore, viscosity of the material is lowered rapidly and time required for an injection process is shortened drastically.
