Patent JP-H0352249-A (JP)
Title: Manufacture of semiconductor device
Inventor: YAMADA YUTAKA
IPC: H01L21/67
Filed: 1989-07-20
Abstract: PURPOSE:To make it possible to remove cut scraps formed by the cutting of a wafer effectively by evacuating air in a space formed at a gap between the lower surface of adhesive tape and a peak-shaped projection of a mounting table so as to form a vacuum state, removing protecting tape, and taking up chips one by one. CONSTITUTION:Many chips 10a are formed in a wafer 10 by full cutting. The wafer 10 is stuck to adhesive tape 14. The adhesive tape 14 is mounted on a mounting stage 20 on which a plurality of peak-shaped projections 20c are formed. The projections 20c are alinged at a pitch that is smaller than the size of the chip. The surface of the wafer 10 is covered with non-adhesive protecting tape 22. When the adhesive tape 14 is mounted in this way, a space at the inside of an outer wall 20b is tightly closed with the adhesive tape 14. Then air is sucked through a nozzle 20d. Then the tightly closed space is evacuated to the vacuum state, and the adhesive tape 14 is lowered. Therefore, the tape is pushed up with the peak-shaped projections 20c. Cut scraps 16 in a cut groove 18 fly up forcefully. The scraps stick into the lower surface of the protecting tape 22, or the scraps are sucked with static electricity. Thus, the cut scraps are attached to the protecting tape and can be removed.

IPC: H04L5/16
Filed: 1994-08-10
Abstract: PURPOSE:To provide a synchronous communication system in which the increase in a delay time is suppressed when one frequency simultaneous transmission reception system is configured via a relay station. CONSTITUTION:A relay control section 1-3 is provided in a signal path between radio equipments 1-1 and 1-2 of a relay station 1 and a timing for changeover of transmission and reception between radio equipments 2, 3 at a terminal station is set in synchronism with a predetermined time slot by the relay station 1 by controlling a signal transmission time between the radio equipments A and B. Since the burst signal subjected time compression in the one-frequency simultaneous transmission reception system is directly relayed in the relay station 1 without any modification, the increase in the delay time due to repeated time compression and expansion is avoided and the communication without a sense of incongruity is attained.

Abstract: PURPOSE:To prevent leaning of the air-fuel ratio while a torque shock at the time of return is restrained by gradually conducting fuel return with a decrease correction corresponding to a lowering of an engine rotating speed on detecting the end of the decelerating condition. CONSTITUTION:In case of decelerating operation where a throttle valve 10 is totally closed and the engine rotating speed is higher than a designated value, fuel cut is conducted, and at the end of decelerating condition, it is returned to the fuel supply condition. That is, the fuel return control in a control unit 12 is made first in such a manner a to gradually reduce the decrease value according to correction factor set to the decrease side when the engine rotating speed drops to the return rotating speed under the fuel cut condition during deceleration. After that, the correction factor gradually changes to a designated value on increase side to make correction for increase. Thus, while a torque shock at the time of decelerating fuel cut return is restrained, it is possible to reduce the period of leaning of the air-fuel ratio caused by an increase in fuel adhering to the interior of an intake pipe when the fuel is increased.
