Title: Reflection optical coupling device
Inventor: SUZUKI HIDEHIKO
IPC: H01L31/12
Filed: 1993-06-08
Abstract: PURPOSE:To improve breakdown voltage by smoothing punched areas on the underside of the element mount surface of a lead frame, and thereby allowing potting material to creep to the underside. CONSTITUTION:Optical transmissive resin 105, such as silicone resin, is potted on the upper side of beds 101a and 102a. Thus the beds 101a and 101b, a luminous element 103, a light receiving element 104, and a gap between the beds 101a and 102a are integrally sealed with the optical transmissive resin 105. After filling the gap between the beds 101a and 102a, the optical transmissive resin 105 extends to the underside of the beds 101a and 102a. As a result, the creeping distance W1 of the lower part of the optical transmissive resin 105 is approx. 1.7mm, approx. 1.5 times WO. Creeping distance of optical transmissive resin in a gap between beds is increased as mentioned above; therefore, breakdown voltage is improved without degradation in photoconductivity.

Abstract: PROBLEM TO BE SOLVED: To provide a durable and safe strut supporting foundation by providing a foundation body composed of an elastic structure having a flexible structure part at least in one direction in the lower part of the strut. SOLUTION: A foundation body 2 is provided in the lower part of a strut 1.

Title: Treatment of cold heat water for ice storage
Inventor: ADACHI KENJIRO
IPC: C02F1/62
Filed: 1999-05-18
Abstract: PROBLEM TO BE SOLVED: To suppress the precipitation of fine crystals of a dissolved solid accompanied by cooling and to enhance cold accumulating efficiency by substantially removing cations of aluminum and zince dissolved in cold accumlating water within a temp. region exceeding 0 deg.C prior to cooling cold heat water to 0 deg.C or lower in a supercooling device. SOLUTION: When cold heat water for ice storage capable of accumulating cold heat is cooled to 0 deg.C or lower in a supercooling device to be treated, cations of aluminum and zinc dissolved in cold heat water are substantially removed within a temp. region exceeding 0 deg.C prior to cooling cold heat water in the supercooling device. That is, cold heat water is brought into contact with a cation exchanger to substantially remove aluminum and zinc from cold heat water by the ion exchange with aluminum and zinc ions. As the cation exchanger, a cation exchange resin is used. Further, by chelating dissolved aluminum and zinc, aluminum and zinc hydroxides may be substantially removed.

Title: Manipulator using elastic contractional body
Inventor: NEGISHI KOICHI
IPC: B25J18/06
Filed: 1989-06-01
Abstract: PURPOSE:To miniaturize and lighten and to eliminate an environmental pollution by arranging an elastic member producing the elastic force resistant to the contraction force of an elastic contraction body between linking members. CONSTITUTION:When a pressurizing fluid is applied on the elastic contraction body 16a of an assembly body A and the pressurizing fluid is discharged from the other elastic contraction body 16b, an elastic contraction body 16a is contracted in the axial line direction against a compression spring 40 and on the other hand the other elastic contraction body 16b becomes extended in the axial line direction by the actions of the elastic restoring force of itself and the elastic restoring force of the compression spring 40. As a result, the link member 14a of one part of the assembly body A is made to perform a rocking movement around the initial position in the direction shown by an arrow mark D so as to approach to the fixing part 44 side at its part located at the elastic contraction body 16a side. Consequently, the remaining assembly body located at the side separated from the fixing part 44 takes a new position based on the rocking movement, while the assembly body located at the side approaching to the fixing part 44 does not move at all, excepting the assembly body A.

Title: Extinction ratio compensation circuit
Inventor: IMAMURA KEIICHI
IPC: H04B10/564
Filed: 1989-05-31
Abstract: PURPOSE:To stabilize the extinct ratio of an outputting optical signal by providing a function compensating effectively the fluctuation of the extinction ratio of an LD due to temperature change or the like. CONSTITUTION:When a signal amplitude of a light emitting element LD is large and a signal amplitude outputted from a monitoring PD is larger, the peak value held in a peak holding circuit is increased, a noninverting input level of an operational amplifier IC 3 rises and an output is increased. The change in the voltage is transmitted to the transistor(TR) Q3 of a light emitting element driving circuit via an inverting integration circuit (c) composed of an operational amplifier IC 4, resistors R9, R10 and a capacitor C3. Since the integration circuit (c) is of inversion type, the base potential of a transistor(TR) Q3 is decreased and the signal component in the optical output is decreased by the light emitting element LD. On the other hand, when the signal component in the optical output is decreased, the base potential of the TR Q3 rises, the LD modulation current amplitude is large and the signal component in the optical output is increased. Thus, the extinction ratio of the light emitting element is stabilized.

Title: Starter
Inventor: SASAMOTO HISAYA
IPC: H02K7/10
Filed: 1990-05-30
Abstract: PURPOSE:To enable an electromagnetic extrusion device to be placed coaxially around a pinion axis and at the same time an entire device to be compact by providing a bridge for branching one part of a magnetic flux where a movable core is formed and for passing through a fixed core when the movable core is moved by a specified amount. CONSTITUTION:A bridge 21 is provided nearly in parallel closer to an inside of a movable core 17 with a slight gap. Further, the distance between this tip and a magnetic pole 19 of a fixed core 16 is shorter than the distance from the movable core 17 to the magnetic pole 19. Thus, the magnetic flux which passes through the movable core 17 appears through the fixed core 16 as well as through the fixed core 16 after passing through the bridge 21, thus resulting in electromagnetic attraction force which is applied between the movable core 17 and the magnetic pole of the fixed core 16 and that which is applied between the bridge 21 and the magnetic pole 19. In addition, since the distance between the bridge 21 and the magnetic pole 19 is shorter than that between the movable core 17 and the magnetic pole 19, magnetic attracting force between the bridge 21 and the magnetic pole 19 becomes sufficiently large.
