IPC: H01L21/20
Filed: 1987-01-14
Abstract: PURPOSE:To form single crystalline thin films aligned in the same azimuth on a whole substrate surface by simultaneously generating many lamellas in a short length to form the gathered state of single crystal regions with the lamellas as seed. CONSTITUTION:When a semiconductor layer 3 on an insulator 1 is irradiated with an energy beam to melt it, lamellas 8 are generated at the valley 6a of a temperature distribution 6, and formed along grooves 2. That is, the lamellas 8 of predetermined length are generated simultaneously at the valleys 6a of the temperature distribution at this time. Since the vicinity regions of the lamellas are recrystallized with the lamellas 8 as seed, the gathered state of single crystal regions 9 with the lamellas 8 as the seed is formed. Thus, single crystalline thin films 10 aligned in the same azimuth are formed on the whole substrate surface.

Title: Radio multiplex access system
Inventor: SAKURAI YASUO
IPC: H04W74/08
Filed: 1984-01-20
Abstract: PURPOSE:To prevent ineffective retention of a radio channel by allowing a base station to inform a busy signal during the use of channel and a collision signal at collision, to a radio equipment. CONSTITUTION:When a mobile set 21 starts communication, a communication request signal with a preamble at the head is transmitted to a base station 1. When the base station 1 detects the preamble, the station uses an outgoing channel and transmits a busy signal to all mobile sets 21, 22. In receiving the busy signal, the mobile set 21 during communication continues the communication and the other mobile set 22 transmitting communication request from now withdraws the transmission. When plural mobile sets 21, 22 transmit the communication request at the same time, the base station 1 detecting it by means of pattern deformation of the preamble or the like transmits the collision signal to the outgoing channel. The mobile sets 21, 22 receiving the collision signal stop immediately transmission, and send out the communication request signal again after back-off is executed.

Abstract: PURPOSE:To control optical output level change caused by characteristics change of a light emitting element, by leading out a part of an optical signal as a monitor optical signal, and controlling the output of the optical signal on the basis of the monitor optical signal. CONSTITUTION:In a light transmitting module 31, an optical signal 3 inputted in an optical fiber 2 by an LD 4 is divided into two parts having a specified ratio by an optical branching element 32.

SOLUTION: Four fitting plates 21 with fitting holes 22 therein are formed on an outer circumference of a flange 20 at the lower end of an ice-making part 1. A frame 24 is fitted on an upper surface of an ice storage house 17 to form a square loading part 25. A receiving base 26 is fixed at the slightly recessed position on the inner side of the sides 25A-25C, and the side 25D is stretched to the receiving base 26 at the same height. A fitting hole 27 is formed in the side 25D and each receiving base 26.

Title: External memory
Inventor: HOSHINO TAKAYUKI
IPC: G11B21/08
Filed: 1992-01-21
Abstract: PURPOSE:To prevent an access error due to disturbance by inserting in series a delay compensation part having a frequency characteristic so that a gain to a low frequency becomes larger than the gain to a high frequency to the output side of a gain decision part. CONSTITUTION:The delay compensation part 16 is inserted between the gain decision part 12 and an adder 14 and has a transmission characteristic GC (S) indicated by the relation of a plus operator S and outputs an estimation speed deviation DELTAVC delay-compensating the estimation speed deviation DELTAV'. The gain GC of the compensation part 16 becomes '1' to a high frequency of a cut-off frequency f2 or above and becomes K (=R4/R1) times to a low frequency of the cut-off frequency f1 or below. Then the influence due to the disturbance in a low frequency area is reduced. In such a manner, by the action of the delay compensation part 16, a disturbance pressurizing characteristic is improved since an observer gain L is set large equivalently to the low frequency area and a wasteful time compensation effect is secured since the observer gain is set as usual to the high frequency area.
