Patent JP-H0231553-A (JP)
Title: Facsimile equipment
Inventor: YAMANAKA YOSHIO
IPC: H04M11/00
Filed: 1988-07-21
Abstract: PURPOSE:To automatically correct the distortion of transmission signals caused by deterioration in the characteristics of a circuit on a transmission side and to eliminate the necessity for level adjustment on a reception side by setting the transmission signals sent to the circuit to the optimum level value by using the reception signal level as a reference. CONSTITUTION:Digital transmission signals 1 are sent to a gain controller 12 after the signals are converted into analog signals by means of a modulator 2. On the other hand, reception level data accumulated in a memory 9 at the time of reception are corrected in accordance with the statistical characteristics of a circuit by means of a corrector 10 and converted into an analog quantity by means of a D/A converter 11. The converted analog signal is used for controlling the gain of the gain controller 12 so that the transmission level of the analog transmission signals outputted from the modulator 2 can be set to the optimum level. The transmission level of the transmission signals is decided based on the data stored in the memory 9. Therefore, no adjustment is required on a reception side.

Title: Manufacture of semiconductor device
Inventor: KURIYAMA TOSHIHIRO
IPC: H01L21/762
Filed: 1985-08-20
Abstract: PURPOSE:To simplify a process by implanting the ions of a substance forming an insulator with the constitient atoms of a semiconductor substrate to the surface of the semiconductor substrate, to which an ion implantation stopping film is shaped selectively, and thermally treating the semiconductor substrate. CONSTITUTION:Ion implanting stopping films 6 are formed selectively to the surface of an Si substrate 1. The ions of oxygen are implanted. Consequently, oxygen atoms are distributed to considerably deep 3a positions from the surface in regions in which there is no film 6 while they are distributed at positions in the vicinity 3b of the surface in regions in which there are the films 6. Si oxide films are shaped at the positions of 3a and 3b through the application of heat treatment. As a result, regions 1a are insulated and isolated completely by the Si oxide films 3a, 3b. According to the method, the films 3a are shaped at a position deeper than the surface in the regions in which there is no film 6, thus eliminating the need for epitaxial growth on the formation of a device. The films 3b as element isolation regions are flattened approximately to the region 1a, thus making processesing time remarkably shorter than a groove isolating method, etc.

Title: Method for synthesizing beryl single crystal
Inventor: TAKEUCHI MASAAKI
IPC: C30B29/34
Filed: 1983-09-30
Abstract: PURPOSE:To grow a large-sized beryl single crystal with little defects at a constant growth speed, by adding a specific flux to a base material, containing rock crystal as silicon dioside, and exhibiting the composition ratio of the beryl, heating the resultant mixture, and forming a molten salt. CONSTITUTION:One or more selected from vanadium pentoxide, lithium molybdate, sodium molybdate, molybdenum trioxide, lithium oxide, sodium oxide, etc. as a flux are added to a raw material, containing beryllium oxide, aluminum oxide, rock crystal as silicon dioxide and chromium oxide as a colorant, etc., and exhibiting ratio of almost beryl. The resultant mixture is then heated at the melting temperature of the flux or above to form a molten salt, and the aimed beryl single crystal is deposited. According to the above-mentioned method, beryl single crystal of high quality can be efficiently grown. This is because the rock crystal is easily melted in the flux as opposed to the quartz without forming an intermediate compound on the surface of the rock crystal and the silicon oxide concentration in the flux can be easily controlled.

Title: Method for assigning channel in cellular mobile object communication equipment
Inventor: KAWABATA TAKASHI
IPC: H04W72/08
Filed: 1995-07-19
Abstract: PROBLEM TO BE SOLVED: To attain a dynamic channel assigning system for suppressing the nimler of tims of channel reassignation. SOLUTION: When communication requests are generated in slave stations in plural cells, a master station for periodically storing the incoming interference wave receiving level of an idle channel stores an incoming frequired wave receiving level at the call originating/terminating time of each slave station (S1). The master station detects information related to non-movement or movement to any direction at the time of movement and receives the information of a moving slave station at the fixed time (S2). An idle channel with the highest priority is selected in accordance with fixed or moving priority table A or B (S3 or S4). An incoming or outgoing CIR (power ratio of a required wave wave to an interference wave) value for the selected channel is judged (S5 or S6).  When the incoming and outgoing CIR values are more than respective prescribed thresholds, the channel is assigning, and when the values are less than the prescribed thresholds and an assigning enable channel can not be detected, forced disconnection or call loss is executed (S7, S8). Consequently the load increment of the master station or the reduction of service quality can be avoided.

Abstract: PURPOSE:To execute antenna diversity by measuring an electric field strength for a predetermined period when amplitude fluctuation is smallest in a specific pattern in a received slot so as to simply measure the electric field strength with high precision thereby using the measured result. CONSTITUTION:A control circuit 16 receives an output of an A/D converter 15 as an electric field strength level detection signal only for a period when amplitude fluctuation is minimized without fail in a received slot, and selects an antenna 1A or a sub antenna 1B as an active antenna by applying switching control to an antenna changeover switch 2 depending on an electric field strength level signal of '1' or '0' level, in the case of e.g. '0'. That is, the antenna diversity is executed. Since the electric field strength is detected for a period when the amplitude fluctuation is minimized in a reception signal, the electric field strength level is detected with high precision even without application of an averaged signal to an electric field strength detection circuit 14 via an averaging circuit having a large time constant.
