Title: Mold for continuous casting
Inventor: KUROKI TAKANORI
IPC: B22D11/04
Filed: 1983-02-01
Abstract: PURPOSE:To improve cooling efficiency and to smooth conduction of cooling water by providing a conduit hole for cooling water in the body of a casting mold, and providing a spiral groove in the inside wall surface of the conduit hole. CONSTITUTION:A conduit hole 2 for cooling water is provided in the body 1 of a casting mold consisting of a blank material having good heat conductivity such as a copper alloy. A spiral groove 5 advancing in the longitudinal direction of the hole 2 is provided on the inside wall surface of the hole 2. The groove 5 may be formed by digging the inside wall of the hole 2 or by disposing a spiral projecting line member along the inside wall so as to form eventually the spiral groove. The groove 5 is formed in order to rotate the cooling water and is therefore not always required to be continuously formed over the entire length of the hole 2.

Title: Fusion splicing method of multi-cored optical fiber tape core
Inventor: ISHIKURA AKIHIKO
IPC: G02B6/24
Filed: 1987-01-28
Abstract: PURPOSE:To permit easy and quick setting of strands of multi-cored optical fibers to V-grooves by simultaneously cutting the strands of the multi-cored optical fibers, then arraying the front ends of the multi-cored optical fiber strands by using an adapter formed by using comb teeth and fitting the fibers together with the adapter into the V-grooves. CONSTITUTION:The fiber retaining adapter 5 is attached onto an upper base plate 3 of a fixing jig for termination. The fibers are inserted to the adapter 5 in such a manner that each piece of the fibers enters the spacing between the comb tooth to eliminate the disturbance in the front end part of the fiber tape cores 1 at the time of stripping the covering of the fiber tape cores 1 with the comb teeth 5c at the front end of the adapter. A step is provided to the multi-cored V-grooves 6a and the head part of the adapter 5 is fitted to the step part, by which the optical fiber tape cores are fixed into the multi- cored V-grooves 6b. The cores 1 enter the corresponding grooves of the V- grooves 6a if the adapter 5 and the V-grooves 6a are worked with high accuracy. The extremely easy setting of the cores 1 to the V-grooves 6 is thus permitted.

Title: Lamp
Inventor: YAMAZAKI HITOSHI
IPC: H01J61/36
Filed: 1983-02-03
Abstract: PURPOSE:To prevent crack and exfoliation at the sealing part to be generated at the time of fixing an external bulb to the shell by sealing an external bulb and an end plate closing the aperture of said external bulb with a first bonding agent and also by providing a second bonding agent for fixing the external bulb to the shell between said external bulb and shell except said sealing part. CONSTITUTION:Since a second bonding agent 11 is isolated from the sealing part A, any compressive stress is not applied to the sealing part A even when it is heated during the fixing work. However, if a second bonding agent 11 is applied up to the area corresponding to the height H of the first bonding agent 5, defective crack or exfoliation at the sealing part A increases rapidly. Since a dent 16 is formed at the neck part 2, it can effectively be prevented that the second bonding agent 11 is stuck to the sealing part A at the time of loading the shell 10, by previously coating the inside of the dent 16 with the second bonding agent 11. Moreover, this dent 16 adsorbes the cubic expansion of the second bonding agent 11 at the time of fixing work and thereby the amount of second bonding agent 11 leaking to the sealing part A can be reduced. These are effective for suppressing the defect at the sealing part A.

Title: Method of sealing photodetector
Inventor: FUKUDA KAZUHIKO
IPC: H01L31/02
Filed: 1988-01-26
Abstract: PURPOSE:To make it possible to perform sealing in an environment wherein high cleanliness is maintained, by providing a double-surface bonding sheet between a photodetector and a glass cap, and bonding both parts. CONSTITUTION:Attachment preventing sheets are stuck to both sides of a double- surface bonding tape, and a tape shaped double-surface bonding sheet is obtained. The bonding sheet is blanked with a metal mold. The metal mold is used for blanking a material into a specified shape. Thus, a bonding sheet 11 is formed. Then, the attachment preventing sheet is peeled off. Since the bonding sheet 11 is liable to yield dust, the dust yielding is prevented by the following way: the sheet is heated so that a resin bonding agent is not deformed with heat and its hardening does not progress; and the surface of the resin bonding agent is smoothed. The double-surface bonding sheet 11 is mounted on a frame shaped surface 41 that is formed on the upper surface of a photodetector 4. A transparent glass cap 3 is mounted on the sheet. Then, a compressing and fixing plate 6 is mounted on the glass cap 3. The plate is held with compressing tools 71 and 72 and compressing levers 81 and 82. The device is compressed. The device is heated with a heater 9 and left alone. The resin bonding agent is hardened, and the glass cap 3 is bonded to the light receiving surface of the photodetector 4 through the bonding sheet.

Title: Self-exciting oscillator
Inventor: WATANABE YOSHIO
IPC: H03B5/12
Filed: 1988-01-29
Abstract: PURPOSE:To make a base current approximately constant with respect to a supply voltage by connecting a constant voltage element through impedance such as a resistor to a secondary winding output edge on an inductance in an oscillation circuit, and obtaining the base current of a transistor from the constant voltage element edge through the impedance. CONSTITUTION:When the conduction of a transistor 2 is started, the supply voltage is impressed to an inductance 4. Consequently, a voltage VL in proportion to the supply voltage is generated on a base winding 5. At such a time, the charged voltage of a capacitor 9 is charged so as to be a constant voltage VD fixed by a constant voltage element 7. For this reason, the current flows through the capacitor 9 the base emitter of the transistor 2  the winding 5  a resistance 6 the capacitor 9. When the voltage of the capacitor 9 is inversion-charged and arrives at a constant voltage VS fixed by a constant voltage element 8, the current thereafter does not flow through the base of the transistor 2. Consequently, since the charge quantity of the base driving current of the transistor 2 becomes constant regardless of the fluctuation of the supply voltage, the collector current of the transistor 2 is made approximately constant.

Abstract: PURPOSE:To expand a scanning range and to shorten a scanning time by scanning a plurality of probes of a scanning-type microscope. CONSTITUTION:In order to maintain a clean surface, a scanning-type tunnel microscope 13, which can be operated in an ultrahigh vacuum state, is used. For probes 11, W (tungsten), which has undergone electropolishing, is used. In order to attach a gold atom 14 on the tip of the probe, the probe is brought close to the surface of gold, and a positive voltage is applied on the probe 11. After the probe is arranged on the specified position of the surface of SiO2, a negative voltage is applied on the probe. The gold atom 14 is moved on the surface 12. By the same way, the gold atom 14 is manipulated again. The next gold atom 14 is manipulated on the surface 12 and arranged so that this atom is separated from the previous gold atom by 0.1mum. This procedure is repeated. Then, with the surface being maintained clean, W is selectively grown only at the part of the gold atoms by chemical vapor growth. Signal plugs are arranged on a plurality of the manufactured probes. The probes are brought close to an Si surface 16 in an ultrahigh vacuum state. When a tunnel current is detected, the approaching of multiple chips is stopped. A piezoelectric element 15 is operated, and the Si surface is finely moved and adjusted.
