Title: Metallizing method of back surface of semiconductor wafer
Inventor: MARUYAMA YUTAKA
IPC: H01L21/60
Filed: 1980-02-18
Abstract: PURPOSE:To improve the reliability of the semiconductor wafer by setting the temperature of evaporating gold on the back surface of the wafer lower then the gold- silicon eutectic temperature, thereby preventing the deterioration of the characteristics thereof. CONSTITUTION:The gold 12 is evaporated on the back surface of the silicon wafer 11, and the temperature is set lower than the gold-Si eutectic temperature 370 deg.C, such as, for example, 350 deg.C and the like. After the wafer 11 thus evaporated with the gold 12 is isolated from the chip, it is mounted on the ceramic substrate plated with the gold. Thus, the Si is not exposed on the surface evaporated with the gold on the wafer, but the oxidation of the back surface of the wafer can be prevented, and the reliability can be improved without deterioration of the characteristics thereof.

Title: Hearth roll for heat treatment furnace
Inventor: NISHIO YASUSHI
IPC: C04B41/87
Filed: 1995-01-10
Abstract: PURPOSE: To provide a carbon roll which improves an easily oxidizing property as the weak point while utilizing the characteristic of the carbon roll and has excellent oxidation-preventing effect from a low temp. range in comparison with the conventional roll and can be provided in a low cost. CONSTITUTION: A hearth roll for heat treatment furnace is composed of a composite material of the carbon unnecessitated to the oxidation-preventing treatment at the time of using this roll with carbide, nitride or carbonitride. This carbon roll as the hearth roll for heat treatment furnace can be used by immediately setting in the furnace after working to the roll shape. By this hearth roll, since a device for impregnating the oxidation-preventing material is unnecessitated and a process is shortened, the roll can be provided in the low cost. Further, since the deterioration caused by oxidation is little, the roll can be used for the long term and the unit requirement of the roll can be reduced.

Title: Communication system
Inventor: MARUKORUMU MATSUKONAACHIE
IPC: H04L13/00
Filed: 1983-02-08
Abstract: A communication system has a first station (SO) and a plurality of further stations (S1-S4), two communication channels (A, B), for transmission in opposite directions, serially connecting the stations. The first station includes routing means operable in a double looped mode to route signals received on each channel onto the respective other channel and the further stations each including routing means operable in a through mode to forward, in the same channel, signals received on each channel, thereby forming a single folded transmision path. Preferably the further stations each are responsive to the cessation of signalling energy (e.g. a break in the transmission path) on a channel to assume a looped mode in which signals received in the other channel are rerouted onto that channel, with the first station responding by assuming a through mode in which signals received on each channel are forwarded in the same channel, again forming a single folded transmission path following rerouting at two of the further stations.

Abstract: PURPOSE:To attain sufficient optical coupling between a laser and a photodetector and at the same time block unnecessary interaction between both by a method wherein the inclination of the end surface of each of the photodetector and the laser facing to a groove part are set in the range of specific angles. CONSTITUTION:The monitor built-in semiconductor laser consists of the laser part 8 and the photodetection part 7, and the groove part 9 is formed between both. This groove part 9 is formed in expansion toward the end, the inclinations 12 and 13 opposed to the direction rectangular to the layer surface of layer form crystals of etched end surfaces 10 and 11 of each of the laser part 8 and the photodetection part 7 are set at 5 deg.C or more and 15 deg.C or less. In other words, the light from the photodetection part 7 comes not to reversely invade into the laser part 8 by setting the inclinations 12 and 13 of the end surfaces 10 and 11 at 5 deg.C or more. The light emitted from the laser part 8 is projected to the active layer 3 of the photodetection part 7 in a sufficient amount by setting the inclinations at 15 deg.C or less. Thereby, stable actions without generation of unnecessary interaction are attained.

IPC: H03G3/30
Filed: 1982-02-12
Abstract: PURPOSE:To realize the use of an APC circuit with a wide range of transmission power and stable operation, by providing a large attenuation for the APC circuit. CONSTITUTION:A figure shows an example of a building block diagram, and 11 is a power amplifier and 12 is a gain control amplifier circuit. An output setting section 18 is used to set the transmission power with a signal in esponse to a reception electric field detected at a receiver, for example. 15 is an amplifier of a constant gain, 16 is a detector, and 17 is a differential amplifier, which compares an output voltage of the detector 16 with a reference voltage 19 and uses an error voltage equivalent to the difference of them for a part or all of a bias voltage of the gain control amplifier circuit 12. The gain of the amplifier 17 is always constant. Thus, the stability of the loop system to the transmission power control is independently of the output power, and the design is performed, taking the frequency response of the loop system only into account.
