Title: Polyester film for packaging
Inventor: UCHIUMI SHIGEO
IPC: B29L7/00
Filed: 1984-10-26
Abstract: PURPOSE:To obtain polyester film for packaging with excellent transparency and slipperiness, printability and productivity by a method wherein the degree of surface orientation DELTAP of film, the F5 value in the longitudinal direction of the film and the mean refractive index (n) satisfy a specified relationship and at the same time the haze of the film is below a specified percentage. CONSTITUTION:The relationship among the degree of surface orientation, (n) and F5 is represented in the attached formula. Polyester chips, which consist in blending and mixing additive, adhesion imparting agent and polyalkylene glycol with a molecular weight of 300-200,000 are extruded from an extruder so as to be cooled and solidified on a rotating cooler in order to form un-orientated polyester sheet. The resultant sheet or film is stretched in the direction of the first axis so as to obtain its birefringent index DELTAn of 0.80 or less and, after that, stretched again under a temperature nearly same as before in order to form biaxially orientated film and to finally set the film under heat. The total haze and surface haze of the film must be not more than 5% and 4% respectively. Because the orientation is lowered so as to satisfy the attached formula, the concentrated stress at the periphery of each particle becomes low, resulting in making the development of voids difficult and consequently decreasing the internal haze and improving the transparency of the film.

Filed: 1999-08-06
Abstract: PROBLEM TO BE SOLVED: To obtain a synchronism acquisition device which can suppress an increase in circuit scale accompanying synchronism acquisition which is made faster through parallel processing. SOLUTION: For synchronism acquisition, code generators 12 used for demodulation generate the same spread codes and a delay unit 15 give mutually different delay quantities to detect correlations of different timing at the same time by a reverse spreading device 13 and a correlation detector 16 used for demodulation; and an autocorrelation peak is found among those correlation values and the spread code generation timing is delayed according to the delay quantity. Thus, blocks used for demodulation are used for synchronism acquisition to suppress an increase in circuit scale.

Title: Facsimile equipment
Inventor: GOTOU HIROSUKE
IPC: H04M1/27
Filed: 1992-08-25
Abstract: PURPOSE:To surely transmit a document by changing the frequency in recalling based on the frequency in failure in a certain period. CONSTITUTION:When the start button of an operation part 2 is depressed after the document is set and the destination is inputted, a recording area for destination information is generated in a memory 5, and the destination is set, and default values are set as the frequency in recalling and the recalling time. After the document is read, a file number is given to this document and is written in destination information. Destination information is transferred to a transmission task by a monitor part; and when the task is started, normal transmission is started in accordance with destination information. When transmission is normally terminated, the communication history is written. Next, destination information and the document file are erased. If it is not normally terminated, the communication history is written, and next, the frequency in recalling is decreased and the communication history is traced back by a certain period to calculate the frequency in failure. Only when it exceeds a preliminarily set frequency, the frequency in recalling is increased. Thus, the document is surely transmitted.

Title: Automatic air bleeding device of fuel circuit of diesel engine
Inventor: SAKAI YOSHIHIKO
IPC: F02M37/20
Filed: 1996-08-07
Abstract: PROBLEM TO BE SOLVED: To automatically discharge the air contained in the fuel when an engine is started by mounting a control valve which is opened when the pressure is below the prescribed value and returns the air or the fuel containing air to an upper part of a chamber for the filtered fuel by a fuel filter and a fuel inlet part or the like of a fuel injection pump. SOLUTION: When an engine is started, and a key switch is set to the starting position, a first feed pump and a fuel injection pump are driven, and the fuel is passed from a fuel tank through a shut-off valve 20 which is a control valve via a fuel filter and a spill piping, and returned to the fuel tank. When the resistance in passing a hole of a valve 22c is increased, the valve 22c is pressed toward the fuel tank side against a spring, and the fuel is fed to an inlet (a gallery 3a) of a fuel injection pump. When air is entrapped in a piping from the fuel tank to the fuel filter and a part of the fuel filter, the valve 22c is in the opened condition and the air is pushed to the fuel tank side through the spill piping.

IPC: G01L19/08
Filed: 1995-08-09
Abstract: PROBLEM TO BE SOLVED: To allow the vicinity of an inspection window to emit a light by laminating a light reflective label color coded to be distinguished on the surface of a scale core or charging a luminous body in the core made of transparent synthetic resin. SOLUTION: The pressure gage 1 comprises a diaphragm 7 to be deformed to be expanded upon reception of a pressure, a scale core 5 disposed on the diaphragm 7, a spring 3, and an inspection window 4 mounted between housings 2 and 8 (moving position of the core 5). A light reflective color coding label 6 color coded to be distinguished is laminated on the core 5. Since the core 5 is color coded by laminating a light reflective film, the pressure can be easily confirmed by emitting a light in a dark environment even if it is not approached near at hand. Further, when a pressure cuff is used, the core 5a can be illuminated from the interior.

IPC: G03F1/00
Filed: 1983-11-29
Abstract: PURPOSE:To enable exposure of two faces having an angle without holding again a substrate by making the substrate holding part of a substrate holder turnable and exposing one surface of the substrate then turning the substrate holding part and exposing the other one surface to be formed at an angle. CONSTITUTION:A metallic fitting 26 for mounting a substrate is attached turnably via bearings 30, 30' to metallic fittings 27, 28 for supporting. A mask 18 and the surface 19a of a substrate 19 are brought into tight contact with each other by adjusting a positioning means 21 and a substrate holding member 20 is sucked under vacuum and fixed to a positioning means 21. The parallel light from a light source 15 for exposure is passed through the mask 18 and is irradiated to the substrate 19 to expose the substrate thereby sensitizing the necessary part of the photosensitive resin film 19e of the substrate 19. The fitting 26 is moved and thereafter the fitting 26 is turned to bring the surface 19b of the substrate 19 and the mask 18 into tight contact with each other thereby exposing the surface 19b of the substrate 19. The exposing operation is accomplished by turning the substrate holding member.

Title: Casting of molten metal and apparatus for implementing the same
Inventor: BUARUTAA DEIITORIHI
IPC: B22D39/00
Filed: 1989-09-01
Abstract: PURPOSE: To achieve separation from the lower part of a flow-out opening part while surely centering casting material stream by guiding the free-dropping of the casting material stream while passing through at least one of magnetic field rotated with the vertical axis as center. CONSTITUTION: As the magnetic field, the rotating magnetic field with stators of a poly-phase motor is used. A kind of slippage is generated at least in the upper side portion of the dropping route between the casting material stream 6 and the rotating magnetic field. Torsion is generated during free-dropping with eddy current in the inner part of the metallic material stream related to this slippage and the casting material stream 6 is rotated with the vertical axis A as center with the characteristic of the accurate adjustment to the straight stream by this torsion. Further, in such a case, since the stable material stream guidance is obtd., the casting material stream is not continuously slipped in the side direction or vibrated.  In this way, at the time of executing a precision casting, the casting material stream 6 can be guided into the extremely narrow opening part in a precision casting mold. Further, e.g. in the case that the casting mold is made of a mineral material, the erosion of the material is avoided.
