Title: Rolling bearing
Inventor: MITAMURA NOBUAKI
IPC: F16C33/62
Filed: 1997-06-16
Abstract: PROBLEM TO BE SOLVED: To provide a rolling bearing which can surely have wear resistance under severe conditions and improve its life. SOLUTION: A race (outer ring, inner ring) and a rolling body (ball) have hardness of not less than 600HV at 300 deg.C at the surfaces thereof and are constituted by carbides and carbonitride deposited on the surface whose maximum particle size is not more than 5μm. Since the surface hardness is specified at a high temperature of 300 deg.C, the race and the rolling body has surely wear resistance of not less than a predetermined value to improve the life of a bearing. Since the maximum particle size of the carbides and carbonitrides deposited on the surface are not more than 5μm by hardening of the surface, roughness of the surface caused by wear is reduced to improve wear resistance and durability life of the bearing.

Title: Communication system
Inventor: KUNITO YOSHIYUKI
IPC: H04B1/69
Filed: 1996-07-04
Abstract: PROBLEM TO BE SOLVED: To provide the communication system to an asynchronous transfer mode(ATM) exchange according to the bus type topology which is suitable for connecting numerous communication nodes with a low transmission rate. SOLUTION: An ATM exchange 6 provides an output of data sent to a clock 60 and an address of the clock 60 to a protocol converter 600. The protocol converter 600 applies SS modulation to the received data, to generate a transmission signal and sends the signal to the ATM exchange 6, via a commercial power supply cable 54. The clock 60 demodulates the received transmission signal by the SS system to reproduce user information from the ATM exchange 6, to make interlocking with other home use devices, such as a coffee pot 58 and an air-conditioner 66.

IPC: H04Q9/14
Filed: 1987-07-14
Abstract: PURPOSE:To detect variation speedily, to detect time deviation simultaneously with sampling time synchronism, and to measure a transmission delay time accurately and speedily by varying a transmission time with a sampling synchronizing signal. CONSTITUTION:A main station 1 consists of a sampling synchronizing signal generation circuit 11, a counter 12, a comparing circuit 13, and a storage circuit 14, and the counter 12 begins to clock the time at the same time the transmission of the sampling synchronizing signal from the circuit 11. In this case, the counter 12 counts up until the sampling synchronizing signal is sent back from a reception-side slave station 2, and stops counting up with the sent-back signal. The sent-back signal is compared with the value of a reference time which is stored previously in the circuit 14 and required for normal transmission from the main station 1 to the slave station 2 and backward transmission. When they do not match with each other, the circuit 13 generates and sends out a discidence signal as the abnormality of a sampling circuit. Consequently, variation in the transmission time can be detected speedily, time deviation detection in enabled simultaneously with sampling time synchronization, and high-accuracy sampling is performed.

Filed: 1994-07-27
Abstract: PURPOSE:To improve print quality by revising setting of a transfer speed of image information in accordance with the image information amount of an image information buffer, thereby preventing decoding and printing from being stopped and avoiding occurrence of white stripes. CONSTITUTION:The transmitted information data are received by MODEM interruption resulting from the reception of a call by a network control section 57 and a MODEM 56 demodulates the received data. Then the demodulated image information is written in a buffer 60a and stored therein. When a storage byte number in the buffer 60a reaches a threshold level (transfer speed), the threshold level is set to a byte counter in a communication control section 55 to transfer the image information from the buffer 66a to a buffer 60b. In this case, a system control section 59 compares number of image information bytes with a current threshold level and revises the setting of the threshold level depending on the comparison result. A control section 59 reads image information in 1-byte and transfers it to a coding decoding section 53, in which the information is decoded.

IPC: H04B10/67
Filed: 1995-06-19
Abstract: PURPOSE: To enable an operation with an optimum bias voltage regardlessly of the value of optical input power. CONSTITUTION: An optical signal received by an avalanche photodiode APD 31 is automatically gain controlled by an AGC amplifier 35 and becomes the output signal of a light receiver. The output signal is fed back, and the output signal of the light receiver is stabilized. At a Zener diode 37, the temperature of the APD 31 is detected and corresponding to the temperature, a voltage almost equal with a breakdown voltage Vbr is outputted from a first bias power source 42 and becomes a bias voltage VB of the APD 31. When the light input of the APD 31 is enlarged and the potential of the cathode of the APD 31 is made lower than the output voltage of a second bias power source 49 by voltage drop caused by a resistor 45, a diode 47 is conducted and the bias voltage VB of the APD 31 is applied from the second bias power source 49.  The output voltage value of the second bias power source 49 and the value of a resistor 48 are selected so that the APD 31 can not be saturated and thermal destruction can be prevented from occurring by letting a large photoelectric current flow.
