Title: Packaging material and its manufacture
Inventor: WISSGOTT ULRICH
IPC: D06M15/15
Filed: 1997-04-04
Abstract: PROBLEM TO BE SOLVED: To improve resistance against fat by a relatively simple manufacturing method and to improve mechanical properties by forming a film containing specific amounts of egg white, plasticizer, emulsifier and water. SOLUTION: Film solution containing about 60 to 70wt.% of egg white, about 25 to 30% of plasticizer, about 5 to 10% of emulsifier and about 3 to 8% of water is applied to a substrate, solidified, and the film is dried. To improve water, moisture and fat barrier properties, the emulsifier such as, for example, acetylated monoglyceride is added to the solution. To ensure satisfactory mechanical properties, the plasticizer such as, for example, polyethylene glycol, polypropylene glycol or glycerol is added to the emulsifier to increase elasticity of the coating substrate. To obtain further excellent homogeneity film, lecithin is added to the solution of the egg white and water before adding the plasticizer and emulsifier solution. After the substrate is coated, the coating is solidified by heat treatment.

Title: Paper feeder for printer
Inventor: IMAMURA SHIYUUJI
IPC: B65H5/00
Filed: 1984-04-27
Abstract: PURPOSE:To enable automatic judgement on whether an envelope is present by arranging a paper detection sensor at the side end of a paper supply path and inward therefrom to detect the presence of a corner-cut in a printer which permits the printing of an envelope as well. CONSTITUTION:Normally, as a paper 19 is inserted into a printer, a paper detection sensor 4 detects the front end side 22 thereof while reading an identifying mark 21 printed on the back thereof to perform the control of the printing position on the paper 19 and the selection of printing data. On the other hand, when an envelope 20 is inserted, the sensor 4 detects a paper 20 depending on the position of a corner-cut 25 of a flap 23 and the printing position is controlled using the detection timing of the sensor 5 as reference. The changing of the control is done by comparing the difference between detection timings of both the sensors 4 and 5 separated at a specified distance with the theoretical value to determine the presence of the corner-cut, namely, whether an envelope is present.

Title: Optical modulating element and projection device therefor
Inventor: SHIMIZU SHIGEO
IPC: G02F1/13
Filed: 1990-03-31
Abstract: PURPOSE:To improve the color reproducibility and contrast ratio of read information by forming the surface of the element at an angle to the optical axis vertical plane of incident light. CONSTITUTION:Light reflected by the surface 24S of the glass substrate 24 of the optical modulating element 10 is made incident on a half-mirror 36 while having an optical axis different from read light because the surface 24S is formed slantingly (F4). Consequently, the axis of incidence on a lens 38 for projection is deviated from the read light and the position of focusing by the lens 38 for projection also shifts. A light shielding body 42, however, is provided on the light output side of the lens 38 for projection and the light can not be transmitted to the side of a screen 44 except through the part of a pinhole 40. The surface reflected light from the optical modulating element 10 is interrupted by the light shielding body 42 and no influence is exerted on a two-dimensional image enlarged and projected on the screen 44. Consequently, the color reproducibility and the contrast ratio of the read information can be improved.

Title: Reserve information printing system
Inventor: OOHASHI YOSHINORI
IPC: G06Q50/34
Filed: 1981-06-06
Abstract: PURPOSE:To enable a pari-mutuel ticket vending device for hose racing to continue original dealing service even when running out a form for copy tickets, by storing data after the form is exhausted in a temporarily register, and then printing and recording them at a time after the form is supplemented. CONSTITUTION:When a form for copy tickets 4 is exhausted, display (no copy ticket) on an input equipment 1 is performed on the basis of the indication of a detection part 19 for the remaining amount of copy tickets. The input equipment 1 sets data successively, and a pari-mutuel ticket control part 14 issues pari- mutuel tickets 3 continuously. During this period, a copy-ticket control part 15 transfers the data in a data register 12 to a stack register 16 and every time one pari-mutuel ticket 3 is issued, the storage position in the stack register 16 is updated successively for the storing operation. When copy tickets 4 are supplemented, said display on the input equipment 1 is turned off by the indication of the detection part 19, so a print command for reserve information is generated with a key 11 to print and record the data stored in the stack register 16 on the copy tickets 4.

Title: Fuel injection device for gas turbine
Inventor: SONE YASUYUKI
IPC: F23D11/12
Filed: 1985-04-24
Abstract: PURPOSE:To suppress cooling effect by the air to an air guide and prevent deposition of carbon thereon by providing circumferentially and with a distance among them a plurality of air guides that are directed to the center of a nozzle around the tip section of a baffle which is directed into the combustion chamber. CONSTITUTION:Air guides 26a at the tip section of a baffle 26 are formed circumferentially around the baffle as circumferential projections with a distance among them. Between two adjacent air guides 26a a flow-out groove 32 is formed. Because the air guides do not encircle the whole circumference but project separately as projections, the surface area of the air guides becomes smaller, and they are not cooled excessively by the sweep air B, and there is not fear that carbon will accumulate on the outer periphery of the air guides 26a. Furthermore, the sweep air B from the air guides 26a is subjected to swirl action by a swirler 19 before it is injected. The sweep air B flows thereby with its component b at the front face which corresponds between auxiliary air injection holes 16 at the tip face of the baffle 26. With this arrangement the carbon liable to deposit on the tip face of a primary nozzle cover 25 is effectively blown away.

Title: Magnetic head
Inventor: KOBAYASHI YOSHITO
IPC: G11B5/187
Filed: 1990-04-02
Abstract: PURPOSE:To obtain a track width of high accuracy and to improve S/N as well as to allow production with high mass productivity by forming hollow grooves opening longitudinally to a medium-facing surface on both side faces in a transverse direction and forming the respective bases of the hollow grooves as surfaces inclusive of the side faces in the transverse direction of a conversion gap. CONSTITUTION:The track width of the conversion gap 3 is determined by the inter-surface spacing between the bases 611 and 621 of the hollow grooves 61, 62 and therefore, the track width of the conversion gap 3 is set at the value of high accuracy. Since the track width is set by the inter-surface spacing between the bases 611 and 621, the magnetic head which allows the adjustment of the track width by the depth selection of the hollow grooves 61, 62 and can deal with high-density recording is obtd. The respective bases 611, 621 of the hollow grooves 61, 62 constitute the surfaces inclusive of the side faces in the transverse direction of the conversion gap 3. The deterioration in the S/N by fringing is obviated and further, the magnetic head having the high accuracy and uniform track width is mass-produced without requiring registration operations.

Filed: 1990-04-04
Abstract: PURPOSE:To reduce the time from the starting of sucking to the perception of the completion of sucking by providing a piezoelectric element between an sucking member to carry out the air suction and a protective plate furnishing a sucking surface to suck a work. CONSTITUTION:A piezoelectric element 2 is provided between a sucking member 1 to carry out the air suction and a protective plate 3 furnishing a surface to suck a work. When the work 4 is air-sucked from a sucking hole 5 and sucked to the sucking surface 8 of the protective plate 3, the pressure that the work 4 gives to the protective plate 3 is loaded on the piezoelectric element 2, and a voltage is generated on the piezoelectric element 2. By perceiving the voltage variation from the signal amplified by an amplifier 9, a sucking completion signal is picked up. Since the electric signal of completing the sucking can be picked up simultaneously with the sucking, the time from the starting of sucking to the completion of sucking can be reduced.
