Title: Device for detecting residual of toner in developing device
Inventor: YAMADA YOSHIHIRO
IPC: G03G15/08
Filed: 1983-12-17
Abstract: PURPOSE:To inform the consumed state of a developer to the user by counting the number of times of development by a developing device from the start of a toner replenish means, and when the counted value reaches a previously fixed value, driving an alarm display part for toner feeding. CONSTITUTION:An original placed on an original platen 1 is formed on a photosensitive body 3 as an electrostatic latent image. A toner image developed by the developing device 5 is transferred to paper by a transfer unit 6. A developer consisting of toner and carrier having magneticity is mixed and stored in a developing tank 52 of the device 5. When a toner density detecting sensor 56 detects a level lower than a fixed density, a microcomputer 25 drives the toner replenish device 56. During the input of a signal indicating the lack of toner from the sensor 55 to the computer 25, the number of copied sheets is stored in a memory device 26. When the device 26 counts up the prescribed number of sheets, a toner feeding alarm display lamp 27 is driven because of the lack of the toner in the toner replenish tank 51. Thus, the toner replenishing can be informed.

Title: Picture transmitting device
Inventor: FUKUZAKI KAZUHIRO
IPC: H04N7/173
Filed: 1990-09-07
Abstract: PURPOSE:To display normal picture data even if line quality deteriorates temporarily by requesting the re-sending of the picture data if a transmission mode is a still picture transmission mode, and inhibiting the display of the picture data if it is a semi-moving picture transmission mode when a data error detecting means detects the error of the picture data. CONSTITUTION:At the time of the occurrence of the error, the data error detecting part 12 stores the presence of the error and its packet number in an erroneous packet presence storage part 21 and an erroneous packet number storage part 22 respectively. A data processing control part 4a detects and processes the received data by separating it into a control frame and a data frame. Simultaneously, a transmission code deciding part 25 discriminates the transmission mode. If the transmission mode decided by the deciding part 25 is the still picture transmission mode, a re-sending request is issued to a remote party terminal. The remote party terminal receives this control frame, and re-sends the picture data. On the other hand, in case that the decision of the deciding part 25 results in the semi-moving picture transmission mode, a data error processing part 28 inhibits the display of the picture data. Thus, the picture data can be displayed in high quality and stably.

Abstract: PROBLEM TO BE SOLVED: To obtain a photosensitive resin compsn. which can be preferably used as a permanent mask material by incorporating a resin containing a specified ethylene-type unsatd. group-contg. polyamide resin component and a specified half amide compd. component in a specified weight ratio range. SOLUTION: The photosensitive resin compsn. contains a resin having 20 to 300 mgKOH/g acid value and 400 to 500000 weight average mol.wt., a photopolymerizable unsatd. compd. having one or more ethylene-type unsatd. bonds, and a photopolymn. initiator. The resin is a mixture of an ethylene-type unsatd. group-contg. polyamide resin (A-1) and a half amide compd. (A-2) obtd. by the reaction of a primary amine and a compd. having at least two carboxylic acid anhydride groups in the molecule. The mixing weight ratio of (A-2)/[(A-1)+(A-2)] ranges 0.1 to 0.7. The ethylene-type unsatd. group-contg. polyamide resin (A-1) is obtd. by first allowing an epoxy resin to react with a specified carboxyl-contg. polyamide resin to obtain an epoxy group-contg. polyamide resin, and then allowing the obtd. polyamide resin to react with a cyclic polyvalent carboxylic anhydride.

Title: Automatic deciding method for binarizing threshold value
Inventor: TAKAGI YUSUKE
IPC: G01B11/00
Filed: 1987-09-25
Abstract: PURPOSE:To automatically decide the binarizing threshold value with which the edge position of a work can be measured with high accuracy by selecting two mountains out of the larger one or two frequency distributions and defining the density at the midslope point of a descending part toward the bottom of a valley from the dark one of both peaks of said two mountains as the threshold value at the binarization processing. CONSTITUTION:A gradation picture of a work 2 is supplied via an ITV 1 and a processing area is set to obtain a frequency distribution, i.e., the frequency (picture element number) H of the density B in said processing area. Thus the big bright and dark mountains are usually shown when a hole 21 is measured by the reflected illumination. Thus the dark and bright mountains correspond to the hole 21 and the upper surface 23 of the work 2 respectively. Then the density of a point where a level higher than the dark peak is secured and at the same time the primary differential dH/dB is first minimized to the density B of the frequency H is prescribed as the threshold value Btau. As a result, the threshold value of density is obtained in response to an edge even though the chamfering is applied to the work 2. Thus the edge position can be measured with high accuracy by binalization.

IPC: B65D41/34
Filed: 1987-09-25
Abstract: PURPOSE:To prevent the breakage of bridging portions at weaking lines during the production of caps and facilitate the breakage of the same at similar positions when a cap is disconnected by forming a circumferentially extending groove on the external surface of a pilferage-proof base portion at least at a position corresponding to the position of a locking means. CONSTITUTION:A pilferage-proof base portion 8 is connected to a main part 7 via a plurality of bridging portions 10. An annular groove 17 is formed in the external surface (external circumferential surface) of the base portion 8, while an annular projecting looking means 13 is formed on the internal circumferential surface thereof. When it is disconnected from a core 21 disposed inside the cap main body 1, the cap main body 1 is forcibly disconnected by moving a stripper plate 20 disposed on the underside of the pilferage-proof base portion 8 in the direction shown by the arrow A. In this condition, the base portion 8 is allowed to deform greatly outwardly due to the provision of the annular groove 17, thus making it possible to disconnect the locking means 13 from the recessed portion 22 formed in the core 21.
