Title: Camera system provided with print cancel function
Inventor: MORISAWA TAHEI
IPC: G03B17/00
Filed: 1994-06-10
Abstract: PURPOSE:To eliminate wasteful prints by installing a recording means to record a print cancel code which cancels printing in an information recording part of an already-picture-taken frame. CONSTITUTION:In a normal photographing sequence, every time a release switch 42 is turned on, the photographing sequence is carried out. At the time of the normal photographing, a picture taking person presses a print cancel switch 43 when the picture taking person judges the photographing frame at the time is a failure and no need to be printed. Since one frame of a film is sent forward by one press of the release switch 42, the film is reeled back by one frame by a driving motor M1 and a print cancel code is recorded in a magnetic recording band corresponding to the photographing frame of a film in which a picture is just photographed. After that, the film is reeled up by one frame again and a frame in which a picture is not yet photographed is set at the tip.

Title: Manufacture of packaging material equipped with foam
Inventor: OKABE MASAAKI
IPC: B29C44/12
Filed: 1987-05-25
Abstract: PURPOSE:To obtain a packaging material excellent in cushioning properties by a method wherein foams in a projected and recessed form are provided on the inner side of packaging material, which is separately mass-produced in advance. CONSTITUTION:Expandable thermoplastic synthetic resin emulsion is applied with brush, roller or the like on the inner side surfaces of a corrugated fiberboard box main body 10. After that, the emulsion is dried in order to remove or reduce the water content in the emulsion. Next, the projected-and-recessed surface side of a mold material 16 is arranged so as to face to the inner side surface of the corrugated fiberboard box main body 10 so as to heat the inner side surface of the corrugated fiberboard box 10 or the inner side, to which expandable thermoplastic synthetic resin 14 is adhered, of the box 10 with heat source having comparatively low temperature such as about 100 deg.C. As a result, the expandable thermoplastic synthetic resin 14 is heated and the resin 14 expands by gas blowing reaction in the inside of the recessed parts 20 of the mold material 16 by about 4-20 times as large as the volume of the resin, resulting in forming cubic and comparatively soft foams 12a with projected cross-section between the inner side surface of the corrugated fiberboard box 10 and the mold material 16.

Title: Scanning light position detecting circuit
Inventor: MIKAMI TOMOHISA
IPC: G02B26/10
Filed: 1983-07-15
Abstract: PURPOSE:To prevent malfunction by fluctuating periodically a luminous amount incident to a photo-detecting means and collating whether the fluctuating period of an output of the photo-detecting means is coincident with the incident light fluctuating period or not to identify whether an output of the photodetector is light-beam or noise. CONSTITUTION:When light-beams MS1-MS3 are incident in a period T to a trihedral mirror 19 while scanning a light-beam MS in the X direction, pulses M1-M3 having a width TP are outputted from a comparator 20 via a photodetector 18. Since an output of monostable multivibrators MM1, MM2 and an FF is ''0'' at the initial state, a differentiating circuit DF1 gives an output at the falling of the pulse M1, a gate G1 is opened to trigger the MM1 and a signal C having a width Td is outputted. When a Q output of the MM1 is logical ''1'' at the rising of the next pulse M2, it is decided as normal light-beam incidence, a gate G2 is opened to trigger the MM2 and a signal H having the width Td is outputted. When no pulse M2 exists at the falling of the Q output of the MM1, the pulse M1 is decided as noise. The FF is set in this case, and each circuit is reset so as to be initialized. A scanning light-beam synchronizing signal generating circuit 21 outputs a synchronizing signal K after the count for a prescribed time by the signal H.

Title: Laminated paper for glass
Inventor: MATSUMOTO KIYOSHI
IPC: B65D85/48
Filed: 1993-05-06
Abstract: PURPOSE:To simplify the cleaning process before using a glass and suppress water repellency, paper mark or burning by incorporating sodium tripolyphosphate to moderate the control range of property. CONSTITUTION:The inter-leaf for glass incorporated with >=0.1wt.% sodium tripolyphosphate is obtained by spraying a sodium tripolyphosphate aq. solution on the inter-leaf for glass and drying to uniformly coat on the fiber surface of the leaf. Sodium tripolyphosphate is transferred from the paper to the surface of the glass so that the trace of the sodium tripolyphosphate exists on the surface of the glass by spreading the inter-leaf between the glasses, transporting and storing. An organic material transferred from the leaf to the glass side simultaneously or after sodium tripolyphosphate is transferred is not in contact with the glass surface directly and is easily removed from the glass by washing. As a result, the glass surface free from water repellency and paper mark is obtained and the proceeding of the burning of the glass is prevented by suppressing the rise of pH on the glass surface by the hydrolysis of sodium tripolyphosphate.

Title: Image forming device
Inventor: FUKUSHIMA HISASHI
IPC: G03G15/00
Filed: 1992-04-22
Abstract: PURPOSE:To eliminate prerotation which is not associated with image forming and to shorten an image forming time. CONSTITUTION:In a four-color full-color printer, a potential sensor which detects the surface potential of a photosensitive body after an electrostatic latent image is formed is arranged. By executing the pre-multi-rotation before copying can be executed after a switch is turned on, for example, potential difference between the first rotation and the second rotation of the photosensitive body is detected. Based on the information of the potential difference, the grid bias voltage Vg2 of the first rotation of the drum after the copying is started is set to be higher than the second and subsequent grid bias potential Vg1 Thus, the surface potential after the electrostatic charge of the first rotation can be made equal to the surface potential V0 of the second and subsequent rotation. Therefore, the prerotation for stabilizing the electrostatic charge property, the sensitivity or the like of the photosensitive body which is conventionally required need not be executed and the image can be formed from the first rotation. Besides, image quality is not deteriorated.

Filed: 1989-05-23
Abstract: PURPOSE:To obtain a performance similar to that of a program generated in a compiler language with respect to data access by executing a program by an interpreter characterized by immediate execution and easiness of generation. CONSTITUTION:It is discriminated whether a data area 37 of a pertinent variable is accessed for the first time with respect to the variable operand included in one object instruction or not. When it is accessed for the first time, a variable entry on a variable name entry 31 to allow a variable 33 and the data area 37 to correspond to each other is scanned; and if the variable entry corresponding to the pertinent variable does not exist, the data area 37 is reserved and the corresponding variable entry is registered in the variable name table 31. Further, the variable name in the variable operand included in one object instruction is substituted with the address to the data area 37, and the data area 37 corresponding to the pertinent variable is accessed by a data address 34 in the variable operand. Thus, the execution time of the object instruction is prevented from being extended.

Abstract: PURPOSE:To improve surge breakdown withstanding voltage, by connecting a drain and a gate to an output terminal, and setting the threshold voltage of a surge absorbing MOS transistor, whose source is connected to one power source, larger than the range of an open drain output voltage. CONSTITUTION:The drain and the gate of a surge absorbing MOS transistor 28 are connected to the drain of an MOS transistor 15. The source of the MOS transistor 28 is connected to a Vss power source terminal 14.

Since the threshold voltage of the surge absorbing MOS transistor 28 is higher than the range of the open drain output voltage, the transistor 28 is not operated at the time of normal operation. The protecting operation is performed only when surge is inputted.
