Patent JP-H06252853-A (JP)
Title: Spatial optical transmission communication equipment
Inventor: SUDA KAORU
IPC: H04B10/112
Filed: 1992-12-03
Abstract: PURPOSE:To reduce power consumption by keeping a proper output for a light emitting element so as to prevent deterioration in the characteristic and the service life even when a communications range and environment or the like are changed. CONSTITUTION:An optical signal 14 transmitted from an opposite station is received by a light receiving element 15 and converted into an electric signal and inputted to an amplifier 16. The amplifier 16 amplifies the received signal and outputs a level signal indicating the strength of the received signal to a discrimination control circuit 17. The discrimination control circuit 17 discriminates the level of the received signal and when the received optical signal 14 is weak, the output of a drive circuit 11 is increased and when the received optical signal 14 is strong, the output of the drive circuit 11 is decreased. Thus, an optical signal 13 outputted from the light emitting element 12 is always kept to a proper level even when the communications range and the environment or the like are subject to change.

Title: Method and apparatus for control of tracking
Inventor: KIN ENTAI
IPC: G11B15/46
Filed: 1993-12-22
Abstract: PURPOSE: To provide a tracking controlling method and device for controlling the speed of a capstan motor by using a variable capstan speed instruction on which a tracking error controlled is reflected. CONSTITUTION: A tracking controlling part 30 obtains a tracking controlled by operating a prescribed gain control to an inputted tracking error, and outputs a variable capstan speed instruction corresponding to the tracking controlled. A capstan motor speed controlling part 32 compares the capstan speed instruction with the actual rotational speed of a capstan motor 36, and outputs the speed error amounts of the capstan motor. A capstan motor driving part 34 drives the capstan motor 36 by a speed controlled in which the tracking error to which the prescribed gain control is operated is reflected on the speed error. Therefore, the control can be quickened, tracking interchangeability among different equipments can be improved, and the gain adjustment and design of this system can be easily attained.
Patent JP-H01167721-A (JP)
Title: Optical isolator
Inventor: MAKIO SATOSHI
IPC: G02B27/28
Filed: 1987-12-23
Abstract: PURPOSE:To obtain reverse-directional loss by setting a <=45 deg. angle between the transmitting direction of the light of a Faraday rotator which uses magneto- optic single crystal manufactured by a floating zone method and the growing direction of the magneto-optic single crystal. CONSTITUTION:A lower figure (b) shows that light is transmitted at right angles of the surface of cubic single crystal cut as shown in an upper figure (b). When the growing direction of the crystal is made to meet the transmitting direction of the light as mentioned above, the in-surface distribution of the reverse- directional loss is extremely excellent. On the other hand, the growing direction of the crystal and the passing direction of the light need not be made completely parallel and even if they have a slight angle, light beams of respective parts pass having similar experience. In general, the shape of the Faraday rotator is almost cubic, so the angle that the growing direction of the crystal and the passing direction of the light contain is set to <=45 deg.. Consequently, when the light is propagated in the opposite direction, the loss increases.

Title: Cable fitted with dampproof dam
Inventor: OHATA KAZUHIRO
IPC: H01B11/00
Filed: 1992-12-03
Abstract: PURPOSE:To see that it does not require surplus mounting space by putting tubes for air bleeding between the cores of a multicore cable, covering its overall length, and charging room-temperature-setting resin between the cores inside its cable sheath. CONSTITUTION:A tube for air bleeding, which have a plurality of air bleed ports, is put between the cores 3 of a multicore cable 1, covering the overall length of the cable 1. Accordingly, the air between the cores 3 in an optional position inside a cable sheath 2 goes out of the cable 1-freely. For this reason, even if room-temperature-setting resin 7 is charged between the cores 3 without stripping the cable sheath, the air inside the cable 1 comes out through the tube 5 for air bleeding, so a required amount of ordinary-temperature-setting resin 7 can be charged between the cores 3 inside the cable sheath 2. Hereby, a dampproof dam can be manufactured without requiring surplus mounting space.

Filed: 1988-12-26
Abstract: PURPOSE:To eliminate disconnection, etc., of leads at a sealing part to enable multi-pin gang-bonding of ceramic packages by a method wherein a resin support ring is peeled off from a lead after completion of themocompression bonding and then a semiconductor chip is sealed. CONSTITUTION:A TAB tape 1 with a chip 4 connected in advance is overlaid on a package 6, an external end of a lead 3 is made to correspond to a package lead 5, a bonding jig 12 is used in this state, and bonding is performed through through holes 9, 10 of the TAB tape 1.

After the lead 3 on the TAB tape 1 is completely connected to an electrode 8 of the package 6, a support ring 2 is peeled off from the lead 3. This prevents thermal deformation of a resin support due to heat treatment at the time of sealing thereafter and stress from being concentrated due to difference in thermal expansion coefficients, eliminating disconnecting, etc., of the lead 3 so that multi-pin gang-bonding of ceramic packages is enabled.

Title: Catalyst for cleaning exhaust gas
Inventor: TANIZAWA RIEMI
IPC: B01J23/648
Filed: 1999-11-17
Abstract: PROBLEM TO BE SOLVED: To enhance the heat resistance of an NOx occluding and reducing type catalyst for cleaning exhaust gas containing TiO2 in its carrier and to still more enhance the NOx cleaning efficiency thereof after high temperation endurance. SOLUTION: In an NOx occluding and reducing type catalyst for cleaning exhaust gas consisting of a carrier comprising porous oxide containing at least TiO2 and the noble metal and NOx occluding material carried on the carrier, vanadium oxide (V2O5) is further supported on the carrier. Since the particle growth of both of TiO2 and the noble metal is suppressed by the presence of V2O5 though a reason is obscure, the NOx cleaning efficiency of the catalyst after endurance is enhanced.
