Filed: 1998-05-14
Abstract: PROBLEM TO BE SOLVED: To effectively eliminate noise at the time of conducting a high frequency range compensation and a modulation by high frequency signals and to conduct an optimum high frequency range compensation. SOLUTION: The device is provided with a laser diode 10 which converts recording signals 'a' to light beams and outputs to a disk. The device consists of a conversion section (an output circuit 1, a high frequency range compensating circuit 2, a bias circuit 3, an adder 4, a converter 5 and a processing circuit 6), which converts high frequency range compensated recording signals 'd' into electric current signals, and a processing section (a processing circuit 6, a high frequency superimposer 7, a switching circuit 8 and a position detector 9) which optimizes the high frequency range compensation conducted for recording signals 'e' of the converter based on the position of the diode 10 with respect to the disk, modulates the optimized recording signals with high frequency signals and outputs the signals to the device 10.  Thus, the intrusion of the noise, which is caused by electromagnetic unnecessary radiation of the high frequency signals, into a preceding stage of the diode is prevented and the waveforms of the recording signals are optimized in accordance with the position of the diode with respect to the disk.

Title: Manufacture of semiconductor substrate
Inventor: YANO TAKAYUKI
IPC: H01L21/76
Filed: 1994-06-14
Abstract: PURPOSE:To decrease the dislocation density of a surface silicon layer and to improve its film thickness uniformity in the manufacturing process of a SIMOX wafer where ion implantation is performed via a protective film. CONSTITUTION:Prior to an inon implantation process, at least two protective films 2 and 3 are formed on a silicon wafer serving as a SIMOX wafer material. Through these protective films 2 and 3, oxygen is ion implanted to form an ion implantation region 4. The protective 2 closest to a silicon wafer 1 comprises a material to serve as a stopper when the other protective film 3 is removed, and the other protective film 3 than the protective film 2 positioned closest to the silicon wafer 1 side comprises a material which least adversely affects the silicon due to the knock-on phenomenon. This enables the dislocation density of a surface silicon layer 5 to decrease and a semiconductor substrate with improved film thickness uniformity to be manufactured.

Title: Display method for operation state of radio set
Inventor: HAGIWARA HIDEYUKI
IPC: H04B1/40
Filed: 1978-10-30
Abstract: PURPOSE: To reduce an operation panel in space by enabling one light emitting element to display the transmission state of its station, in addition to whether a channel where a radio has been set is in use or not.  
     CONSTITUTION: In a transmission mode, switching circuit SW 1  is turned ON-OFF by the detection output of transmitting detector TDT, causing light emitting element LD to come ON-OFF. In one reception mode where no radio wave arrives, switching circuit SW 2  is turned OFF by the noise detection output of squelch circuit SQC to turn light emitting element LD OFF. In the other reception mode where a radio wave arrives, switching circuit SW 2  is turned ON because of no arrival of the noise detection output of squelch circuit SQC, so that the element will come on continuously. Only one light emitting element LD, therefore, provides tri-stage display, reducing its operation panel in component equipment space.

Abstract: PURPOSE:To improve the transmission efficiency by providing a bit showing whether the slot is being used or not, on the head of said slot, so that the transmission eqiupment which has detected that the bit is unused can transfer a data by use of this slot. CONSTITUTION:When the transmission equipment 54 is made to start the transmission by the information processing equipment 55, the channel discrimination part 44 detects an unused channel, the channel number is stored, immediately the transmission operation is started, the command generation part 48 is started, the transfer start command CM and the transmission data length LN are generated, and they are placed on the unused slot which is passing through the shift register 41, and are transmitted. Said channel is occupied by setting the bit showing that the slot is being used, to the slot header SH. Also, it is released by resetting the bit showing that the slot is being used, of the header SH, returning the channel to the unused state, and also erasing the contents of the transmission channel memory part 47. Accordingly, the transmission efficiency can be improved in case when the transfer data length is long, or the data field length in the slot is short.
