Abstract: A lens cap having a lens formed in the window at its top portion, used for a semiconductor laser, etc., using an aspherical lens instead of a spherical lens with large aberration. This invention proposes a lens cap having an aperture formed at its top portion, comprising a lens formed to fill the aperture in such a manner as to bulge on both sides of the aperture and further to extend beyond the circumferential edge defining the aperture along the top portion on both sides of the top portion or under the top portion only, wherein the outer circumference of the portion extended under the top portion contacts the lateral inside wall and top inside wall of the cap member. So, this invention can provide a cheap lens cap with high performance.

Abstract: A tank structure comprises a tank body for storing liquid and control devices for supplying or discharging the liquid to or from the tank body. The tank structure further includes an upper exterior member having a lower flat surface and a lower exterior member having an upper flat surface. The tank body includes an upper and a lower flat surfaces facing the lower flat surface of the upper exterior member and the upper flat surface of the lower exterior member. The tank body is held in sandwiched between the upper and lower exterior members.

Abstract: A molded glass lens with a lens holding cylinder integrated, comprising the lens holding cylinder having an adequate number of through holes formed in it and forming a hot working space together with a mold during molding and a glass lens proper molded in the lens holding cylinder, wherein the excessive portion of the base material of the lens has flowed into said through holes, and also proposes a production device thereof.

Abstract: A combined valve is constructed by integrating a manual valve operating as a safety mechanism and a pilot valve. When a handle of a knob of the manual valve is in a safety mechanism release position, a valve mechanism can be opened and closed depending on whether or not there is air supply to an operation port. When the handle is in the safety mechanism release position and the valve mechanism is even in a valve open state, the valve mechanism can be forcibly brought to a valve closed state by rotating the handle to a safety mechanism set position. Further, when the handle is in the safety mechanism set position, the valve mechanism can always be kept in the valve closed state irrespective of air supply to the operation port.

Abstract: A receiving apparatus that sequentially receives and accumulates a plurality of broadcast contents into a storage medium deletes each content accumulated in the storage medium after a predetermined time period as the capacity of the storage medium is limited. The receiving apparatus is connected to at least one external device, and accepts a user designation of a content to be stored and of an external device into which the content is to be stored. The receiving apparatus schedules the transfer of the content in the available time period of the external device, and transfers the content to the external device if the device is not busy at the scheduled time.

Abstract: A time managing apparatus that manages times clocked by a plurality of timer modules in apparatuses connected to each other on a network. The time managing apparatus has: a holding means for holding event start time information that indicates an event start time at which one or more events should be started by two or more apparatuses on the network; a time requesting means for requesting a timer module to transmit a standard time; a time receiving means for receiving the standard time; a judging means for judging whether the event start time is reached, by comparing the received standard time with the event start time; and an instructing means for instructing the two or more apparatuses to start executing the one or more events when the judging means judges that the event start time is reached.

Abstract: A machine for producing plastic laminates having a feed roller means consisting of a pair of feed rollers for feeding a material to be laminated, a facing type preheater means which allows the material to be laminated which is being fed, to be preheated, while it slides along the preheater means, and a heating and pressing roller means which has both the heating function and the pressing function in one body, for heating and pressing the material to be laminated which has been preheated, resultantly being simple in the structure, small in the external dimension, less expensive in the production cost and capable of producing plastic laminates without discontinuous adhesion to have a beautiful laminated surface appearance.

Abstract: A process for producing a flake style food which comprises adding a dehydrated vegetable and a polysaccharide thickener to a seasoning solution, emulsifying the obtained mixture by stirring at a high speed of from 1,000 to 10,000 rpm within a temperature zone of from 10.degree. to 80.degree. C. for 1 to 10 minutes and mixing the emulsified product thus obtained with one or more of fish meat, poultry meat or cattle meat which is in the form of flakes.

Abstract: A laminated plastic card provided a lamination of a dye accepting layer, a substrate of paper or the like, and a back coat layer, on which lamination one or more patterns are printed with a volatile dye, and a transparent plastic film adhered on the lamination by an adhesive agent, wherein the adhesive agent is a saturated polyester resin having an average molecular weight of approximately 18,000 gm/mole and produced by condensation polymerization of polypropylene glycol or trimethylol propane and adipic acid or azelaic acid.
