Title: Heat treatment apparatus
Inventor: UCHIDA YOSHINOBU
IPC: H01L21/22
Filed: 1990-07-18
Abstract: PURPOSE:To keep a unifrom cross-sectional temperature with high accuracy and to obtain a heat-treatment apparatus which can form a film for a high-quality semiconductor wafer by a method wherein a resistance heating element, whose heat value is substantially a heat value or higher of the unit length of a coil heater is installed at a terminal extraction part. CONSTITUTION:A wafer boat 3 supporting a semiconductor substrate 2 is inserted from an opening part 5 of a reaction tube 4 and a lid body 6 is closed; then, the pressure inside the reaction tube 4 is reduced by using an evacuation system. An electric current which has been adjusted so as to supply a desired electric current is supplied to a coil heater 9 at individual zones 95, 96, 97 via terminal extraction parts 91 to 94 of the coil heater 9, and the reaction tube 4 is heated because the coil heater 9 is heated. At this time, the electric current is supplied to the individual zones 95, 96, 97 of the coil heater 9 through respective sheetlike bodies 12 and crank pipes 11. The cross section of each crank pipe 11 is the same as or smaller than that of the coil heater 9. Each crank pipe generates the same heat as that or higher heat than that of the coil heater 9. Each connecting part 13 of each crank pipe 11 to the coil heater 9 and each part 14 protruding from a heat-insulating material 10 are displaced. As a result, the heat hardly excapes and it is possible to reduce the temperature distribution at a cross section.

Title: Electronic musical instrument for providing play effect similar to stringed instrument
Inventor: TAMURA HIDEKAZU
IPC: G10H7/00
Filed: 1992-06-25
Abstract: PURPOSE:To enable play more approximated to the play of stringed instruments by making the keying operations of a keyboard correspond to the stringing operations of stringed instruments and generating/extinguishing musical sounds similar to the play of stringed instruments with those operations. CONSTITUTION:When the musical sound allocated to a key 17 is not generated and the key 17 is pressed, first of all, the ON/OFF of a switch A is changed. When the same key 17 is pressed before that and the musical sound of that key 17 is not under generating, no processing is performed and next when the ON/OFF of a switch B is changed, that sound is generated. When the musical sound allocated to the key 17 is under generating and the ON/OFF of the switch A is changed by pressing the key 17 under sounding, the sound under generating is stopped. Afterwards, when the key 17 is continuously pressed, the switch B is turned on, and the same musical sound is generated again. Further, when the key 17 under sounding is pressed with a shallow stroke, the ON/OFF of the switch A is changed but the ON/OFF of the switch B is not changed. Therefore, the musical sound under generating is stopped.
Patent JP-S6249710-A (JP)
Title: Array antenna
Inventor: KONDO MIKIO
IPC: H01Q21/28
Filed: 1985-08-29
Abstract: PURPOSE:To improve the characteristics of an array antenna and to make the antenna smaller in size, by linearly arranging each short-circuit post along the arranging direction of conductor plates. CONSTITUTION:Short-circuit posts 3 and 3 of each conductor plate 1 are faced to each other with a feeding point in between on the axial line (x) passing through the feeding point 2. Since the equivalent magnetic flow distribution on the outer peripheral opening of each plate antenna element becomes smaller in the direction (x), in which the elements are faced to each other, under such an arrangement, the electric field induced in another adjacent plate antenna element becomes smaller. Therefore, the mutual coupling quantities among the antenna elements can be reduced as compared with conventional array antennas and no disturbance is produced in the amplitude and phase of the feeding current to each element. Accordingly, any desired radiation patterns are obtained. While the radiation pattern drops in level in the direction (x), the effect of the improvement in the antenna characteristics due to the decrease in the mutual coupling quantities is larger than the influence of the level drop.

Title: Data checking system for integrated circuit card
Inventor: NAKANO HARUMI
IPC: G06K17/00
Filed: 1985-08-29
Abstract: PURPOSE:To detect previously the abnormality of a memory incorporated to an integrated circuit IC card without carrying out a card transaction based on the wrong data, by using a means which compares the check totalization stored against the read data with the check totalization obtained according to the read-out data. CONSTITUTION:The personal identification number PIN stored in a data memory 65 is extracted via a read/write controller 58. The check-sum CS data obtained based on said number PIN undergo the arithmetic through a CS arithmetic part 56a in a system controller 56. A comparator 63 compares the new CS data produced according to the PIN extracted from the memory 65 with the CS data stored in a pair with the PIN. If no coincidence of said comparison is obtained, it is decided that the PIN produced the transformation of data is recorded owing to some reasons like the static electricity, etc. Thus it is possible to know that the memory data has abnormality within an IC card before the cash transaction is actually carried out.
