Title: New linear alkyl sulfide type episulfide compound
Inventor: AMETANI SHOICHI
IPC: C08G75/02
Filed: 1996-08-14
Abstract: PROBLEM TO BE SOLVED: To obtain a new linear alkyl sulfide type episulfide compound which, when cured by polymerization, can give a thick-wall low-chromatic aberration optical material, especially a material desirable for use for lenses such as spectacle lenses by forming the compound so that it may have a structure represented by a specified formula. SOLUTION: This linear alkyl sulfide type episulfide is represented by the formula (wherein (m) is 1-6; (n) is 0-4; X is S or O, and the number of the S atoms is 50% or more of the total number of the S and O atoms constituting the three-membered rings on the average). An optical material made of a cured resin obtained by curing this compound by polymerization can give an optical resin material having a sufficiently high refractive index and a good balance between the refractive index and the Abbe's number, which is difficultly obtainable from prior art starting compounds. Therefore, this compound markedly advances the reduction in the weight, thickness and chromatic aberration of an optical resin material and can give a material desirable for use for lenses for e.g. spectacles.

Title: Impact dot printing method
Inventor: INABA MASAJI
IPC: B41J35/00
Filed: 1984-10-12
Abstract: PURPOSE:To perform sharp printing without excessively abrading the needle like body of an impact head, by using an inked ribbon, of which the substrate is a film, and applying a lubricant to the back surface of the above mentioned substrate immediately before the ribbon is impinged to the needle like body of the impact head. CONSTITUTION:An inked ribbon 6, wherein pressure-sensitive transfer ink layer is provided to the surface of a film base material, is wound up by a core. At the driving time of the ribbon, the inked ribbon 6 is unwound from a core 7 and wound up by a core 7' through a printing part. An occulusion body 11, wherein resin sponge is impregnated with a lubricant, is arranged in the vicinity of the ribbon moving route 8 immediately before the printing of a ribbon car tridge 5 and one end pat thereof is contacted with the back surface of the ribbon 6 to coat the same. Therefore, when a printing image is formed by the needle like body of an impact head 1, the lubricant is adhered to the needle like body impinged to the back surface of the ribbon 6 and transferred to the needle like body holding part of the head 1 to reduce the abrasion of the needle like body at this pat and excessive abrasion is eliminated. As a result, sharp printing is obtained.

Title: Method for energy generation
Inventor: ISHIKAWA AKIRA
IPC: G21B3/00
Filed: 1989-08-23
Abstract: PURPOSE:To produce electric energy easily and cheaply by generating thermal energy by injecting a deuterium into a substance and then by converting the thermal energy into electric energy. CONSTITUTION:A deuterium D2 is generated by a reaction of the equation I by charging negative excess voltage to a hydrogen absorption material such as a palladium or a titanium, in electrolytic liquid 3 containing the deuterium. At that moment, positrons (D<+>) are electrolytically injected into the hydrogen absorption material. The positrons are compressed to a very high concentration by the negative excess voltage and also have very high movability. With that reason, it is conceivable that the positrons can easily collides one another even in a room temperature and a nuclear fusion reaction expressed by the equation II can occur, and, at this occasion, a huge amount of thermal energy is generated.

Then the threshold voltage is set higher than the forward voltage drop VF of the diode. In such constitution, the variance caused in the manufacturing process and the influence of the temperature can be reduced.

Title: Leakage warning system
Inventor: INOUE TAKESHI
IPC: G08B21/00
Filed: 1990-08-14
Abstract: PURPOSE:To prevent an erroneous output from a master breaker by sending a leakage detection signal to a central monitor from the breaker when leakage is detected by a leakage sensor of any branch breaker and detected by own leakage sensor. CONSTITUTION:Breakers having leakage sensors 6, 7 having substantially the same sensitivity for detecting leakage as master and branch breakers 1, 2 are used, and the breaker 1 can receive leakage detection output of the sensor 7 of each breaker 2. When leakage is detected by the sensor 7 of any breaker 2 and leakage 6 is detected by own leakage sensor, the breaker 1 sends a leakage detection signal to a central monitor 3. Accordingly, if no leakage detection output is from the sensor 7 of the breaker 2, a leakage detection signal from the breaker 1 is not sent to the monitor 3. Thus, erroneous output is produced from the breaker 1, and complicated wiring is not required.

Filed: 1983-11-16
Abstract: PURPOSE:To attain the flow rate control over a wide range with a miniature controller by using a bimetallic diaphragm to the valve structure. CONSTITUTION:The flow rate of a path 1 is measured at a detecting part 2 and then compared with a set signal of a flow rate setting device 5 at a comparison/ control part 4.

Title: Task execution controller
Inventor: HASHIMOTO TOSHIAKI
IPC: G06F15/00
Filed: 1989-08-21
Abstract: PURPOSE:To reduce operation for checking whether or not task execution is necessary by setting a subroutine call instruction in an entry in a table corresponding to a task to be executed and executing the task according to the instruction. CONSTITUTION:When the task N is requested to executed, a task execution request means 1 substitutes a branch instruction which is set with the subroutine call instruction to call a task execution part 32. The execution part 32 restores the branch instruction rewritten in the entry of the task which begins to be selected by a task selection part 31. Then the subroutine call instruction in the entry is rewritten into a state wherein it needs not be rewritten into a branch instruction to a next task. The entrance address of the task is found from an entry which is called successively and the control is passed to the entrance; when the task is executed and finished, the control is passed to the task B of a selection part 31. Consequently, when the number of constitution tasks is large and there are many tasks which need not be executed, the overhead of the system is reduced.

Title: Water stop material for underground buried cable with protection pipe and water stop construction
Inventor: ZENITANI YUKIO
IPC: H01B7/288
Filed: 1996-07-26
Abstract: PROBLEM TO BE SOLVED: To enhance water stop performance by giving water permeability to at least one part of a packing material by sealing with a water swelling type water absorbing resin in a packing material consisting of at least two sheets. SOLUTION: A water stop material 1 is placed between a cable 4 and a protection pipe 5 for preventing water immersion into a manhole 7. When using this, a tape-shaped water-stop material 1 is adhered to a cable outer cover with an adhesive, pressed and wound round in a spiral form, and then cut when it almost reaches the inner diameter of the protection pipe 5. Thereafter, the cable is inserted until the portion 6 wound by the water stop material inside the protection pipe 5 reaches the portion immediately before the outlet to the manhole 7. By the water stop construction formed in this way, the water absorbing resin swells and close the gap inside the protection pipe 5 when water immersed into the pipe contacts to the water swelling and water absorbing resin 3, thereby preventing leakage of water into the inner space in the manhole 7.
