Title: Optical transmitter
Inventor: NAKAMURA ICHIRO
IPC: H04B10/40
Filed: 1995-02-15
Abstract: PURPOSE: To shorten the burst response time by amplifying the difference between a binary data signal and the output signal of a light receiving element thus driving light emitting element. CONSTITUTION: The binary data signal applied to an input terminal 1 is impressed to the base of a transistor TR 4 through a buffer circuit 2. When the binary data signal becomes high, the TR 4 is turned on, and the output current of a constant current source 3 flows to a light emitting element 6, and the element 6 emits light. Then, a current flows to a light receiving element 7, and the output current of the element 7 is converted to a voltage by a resistance 8, and it is amplified by an amplifier 9 and is impressed to the base of a TR 5. If the degree of amplification of the amplifier 9 is so set that the TR 5 starts conduction when the optical output of the element 6 reaches a prescribed value, the TR 5 is made to conduct and a part of the output current of the current source 3 flows to the TR 5 when the optical output of the element 5 exceeds the prescribed value.  Thus, the current flowing to the element 6 is kept at a certain value because being limited, and the optical output of the element 6 is controlled each time when the binary data signal becomes high.

Title: Radiator with oil cooler
Inventor: WATANABE MIKIO
IPC: F28F9/02
Filed: 1990-02-06
Abstract: PURPOSE:To improve heat exchanging ability and make the weight of a radiator lighter and more compact by installing an oil cooler, whose cross section is approximately a U-shape, in the lower header of a radiator with its opening facing upwards. CONSTITUTION:The working oil of an automatic transmission passes through a coupler 6 for an inlet pipe and flows through the oil passage 4 of an oil cooler 2 which is built in the lower header 12 of a radiator 1, to come out of a coupler 7 for an outlet pipe. On the other hand, cooling water of the high temperature from an engine enters an upper header from an inlet pipe 16 and while it is passing through a passage 14 of a flat water passing pipe 13 and reaches the lower header 12, it is cooled by the atmosphere. When cooling water flows in to the lower header 12, it passes through an opening part 5 which has the oil cooler 2 of approximately U-shape, so the oil cooler 2 does not interrupt the cooling water flow, to increase the heat exchanging ability because of the small pressure loss. Even if the width of the oil cooler 2 and the width A of the lower header 12 are made smaller, so much increased in its height will keep the heat exchanging ability.

Filed: 1991-01-28
Abstract: PURPOSE:To provide the subject mold excellent in oxidation resistance at high temperatures, free from adhesion of fine glass particles and discoloration and excellent in mold release characteristics. CONSTITUTION:A mold matrix is formed by using one of respective polycrystals of Mo, W, Cr and Ta and Mo single crystal and its oxide 1 is formed on the top layer of the mold matrix.
