Title: Ion implanter
Inventor: KAWASAKI YOJI
IPC: H01J37/317
Filed: 1994-02-02
Abstract: PURPOSE:To obtain an ion implanter which can decrease or eliminate a charge-up phenomenon occurring on the surface of a wafer at the time of ion implantation. CONSTITUTION:A disk pad comprises a peripheral clamper 3 and a central clamper 7 in contact with the surface of a wafer 2 at the center of the wafer 2. This makes it possible to increase the area of a part of contact between an earth potential and the surface of the wafer more than before and to shorten a distance from the farthest part of the clamper to the clamper within the wafer surface, thus making it easier to eliminate charges generating on the wafer surface than before.

Title: Mounting method for electronic part
Inventor: SAKAI TADAHIKO
IPC: H01L21/60
Filed: 1998-01-23
Abstract: PROBLEM TO BE SOLVED: To provide a mounting method of an electronic part, whose reliability of a bonding part is high and which is superior in a bonding part. SOLUTION: In the method, an electronic part where precoat solder 3 is previously formed on the electrode 2 of a substrate 1 and gold bumps 8 on the electrodes 7 of the electronic part 6 are solder-bonded to the electrodes 2 by precoat solder 3 is mounted. Bond 5 containing hardener whose melting temperature is lower than a solder melting temperature is applied to the substrate 1 and the gold bumps 8 are depressed to precoat solder 3 by an application tool 9 so as to heat them. In the heating process, precoat solder 3 is raised to a temperature higher than the solder melting temperature. Thus, the spread of the molten solder on precoat solder 3 and the gold bumps 8 are not inhibited and the highly reliable bonding part of a satisfactory form can be obtained. Then, mounting time is shortened and productivity can be improved by promoting hardening of bond 5.

Title: System and method for external character data registration, and storage medium
Inventor: HOSAKA TOMONARI
IPC: B41J29/38
Filed: 1997-01-27
Abstract: PROBLEM TO BE SOLVED: To securely and efficiently register external characters in peripheral equipment by updating external character registration data of the peripheral equipment only when a host computer and a printer device have different registration IDs regarding the external character registration data. SOLUTION: A printer driver compares an external character registration ID with ID data stored in a storage device 106 of the host computer 101 to judge whether or not alterations are made. When the pieces of ID information of the both are different or when there is no external character registration data present on the printer side, the printer driver sends the external character data registered in an external character registration device to the printer device 103 and an MPU 107 performs a process for updating the external character data registration in an external character registration area in a RAM 108. After the registration update on the side of the printer 103, the registered ID information on the side of the printer device 103 in the RAM 108 is rewritten. After the update, the control exits from this routine.

Abstract: PURPOSE:To effectively utilize a space, to achieve miniaturization and to reduce noise and power consumption by reducing the number of parts, by forming a condensing recessed part to a rotary substrate and mounting the chip of a light emitting element to the bottom part of said recessed part. CONSTITUTION:A cord wheel 14 and a rotary substrate 1 having a light emitting element emitting light toward said wheel fitted thereto are arranged in parallel and a condensing recessed part 2 is formed to the substrate 1 and the chip 4 of the light emitting element is fitted to the bottom part of said recessed part 2. The light emitted from the chip 4 is condensed by the recessed part 2 to reach a light receiving element 15 and, when the wheel 14 rotates with the driving of a motor, the light of the chip 4 transmits through a fixed slit 13 when the slit of the wheel coincides with the fixed slit 13 to reach the element 15. When the light blocking part between the slits of the wheel 14 coincides with the slit 13, the light of the chip 4 is blocked and the pulse like detection signal from the element 15 is outputted. Therefore, when said detection signal is counted, the angle of rotation or rotary position of the wheel 14 is detected.
