Title: Detecting mechanism of film existence
Inventor: YAMAMOTO KATSUHIKO
IPC: G01S17/88
Filed: 1984-12-29
Abstract: PURPOSE:To prevent a picture from deteriorating due to flaws or a film from damaging at the transfer of the film and to check the existence of a rolled film in a camera simply when the existence is uncertain by discriminating a film surface, back paper and the rolled film to detect the existence of the rolled film in a transfer course. CONSTITUTION:A photodetector 22 of the 1st photoelectric detecting member 7 is turned to low impedance only when opposed to the film because the 1st reflecting member 6a has a low reflecting surface and the output (point A, output A) of the succeeding comparator 23 is turned to the low level when the member 7 is opposed to the film and turned to the high level when the reflecting member 6a is opposed to the back paper. Since the 2nd reflecting member 6b is constituted as a high reflecting surface, a photodetector 25 is turned to low impedance when the 2nd photoelectric detecting member 8 is opposed to the 2nd reflecting member 6b and the film and the output (point B, output B) of the succeeding comparator 26 is turned to the low level. Thus, the simple circuit can detect the existence of the rolled film when the level of the output A is the same as that of the output B and the absence of the rolled film when both the levels are different.

Title: Communication equipment for still picture
Inventor: MAEI YOSHIHIRO
IPC: H04N1/413
Filed: 1993-10-08
Abstract: PURPOSE:To suppress irreversible encoding before transmission and to prevent image information from being omitted. CONSTITUTION:An encoder part 42 encodes supplied image information by a reversible encoding system, and stores it in a storage part 43. A capacity discriminating part 46 compares the encoding capacity of a receiver detected by a communication part 44 with that used in a storage, and discriminates whether or not the encoding is required again. When coincidence is obtained between the encoding system and the capacity of the receiver, the image information is sent out from the storage part 43, and when noncoincidence is obtained between them, the encoding is performed again by the encoding system adaptive for the encoding capacity of the receiver. The reading of the image information can be performed after negotiation is held in advance and the capacity of an opposite machine is discriminated. Also, the image information can be stored without performing the encoding, and it can be transmitted after performing the encoding by the encoding system adaptive for the discriminated capacity of the opposite machine.

Title: Ink jet recording device
Inventor: AKIYAMA YUJI
IPC: B41J2/175
Filed: 1988-11-02
Abstract: PURPOSE:To ensure that satisfactory recording is always performed by printing a discharge detection pattern which reveals a discharge state from each color recording head in a non-image recording area where a specified image is not recorded, reading the discharge detection pattern with a photosensor, and recovering ink from a recording head in which ink discharge is not detected. CONSTITUTION:A discharge detection pattern is printed linearly from all 128 discharge orifices grouped in four blocks from the top. It is possible to determine the discharge condition of 32 ink discharge orifices by using a single block. The discharge detection pattern is read with a light sensor 12. Next, it is determined whether ink is discharged or not discharged by variations in the intensity of reflective light detected when ink is charged from every ink discharge orifice and data is printed and when ink is not discharged from the ink discharge orifices and data is not printed. Ink is recovered from a recording head in which the failure to discharge ink is detected. Thus satisfactory image recording is performed and ink is saved by recovery action.

Title: Roughing endmill
Inventor: KONYA YASUO
IPC: B23C5/10
Filed: 1994-10-17
Abstract: PURPOSE: To disperse impact force acting on the top of a tool to keep the strength of a cutting edge longer for obtaining stable tool life by setting up a specified distance between a face and the center position of a cutting edge on the contact part of a workpiece. CONSTITUTION: A roughing endmill carries out concentrated cutting action by only the top of a wave-shaped cutting edge. For this reason, when the pitch of the wave-shaped cutting edge is designated by P, a part to participate in cutting is enlarged by shifting the cutting position of the wave-shaped cutting edge to an oblique face being separated as far as the distance of (0.1-0.2)×P from the top, and synergistic effect with a helix angle can be displayed for softening chamfering impact. In case of cutting by the oblique face of the wave- shaped cutting edge, since a rake angle in the generating direction of chips becomes a large angle which is not only a peripheral rake angle but also that combined with an axial rake angle or a helix angle, notable effect can be obtained in the improvement of a cutting property.

IPC: B05D1/26
Filed: 1992-10-15
Abstract: PURPOSE:To obviate the stringing of an adhesive even when a nozzle is moved immediately after the adhesive is applied on an electronic circuit board. CONSTITUTION:A board 4 is fixed at a specified position, a nozzle 2 is moved to the electronic part mounting position of the board 4, compressed air is introduced to extrude an adhesive 3 in a barrel 1 from the nozzle 2, and a head is lowered to apply the adhesive 3 on the electronic part mounting position of the board 4. A high voltage is impressed on a high-voltage electrode 9 immediately after the head is raised to generate an electric discharge from the electrode 9, hence the adhesive 3 between the nozzle 2 and the board 4 is heated by the heat energy of the discharge, and the viscosity of the adhesive 3 is lowered. Consequently, the stringiness of the adhesive 3 is reduced, the adhesive 3 is surely separated on the nozzle 2 side and on the board 4 side, the adhesive 3 is not applied on the junction electrode of the board 4, and the defective soldering due to stringing is not caused.
