Title: Shadow mask structure for color crt
Inventor: SASAKI TAKESHI
IPC: H01J29/07
Filed: 1991-03-06
Abstract: PURPOSE:To prevent each of a number of strips for a grid from slackening by locating the mounting position of a resilient supporting member and a bow- shaped supporting member on the axis, where the moment of rotation generated by the tension on the grid strips nullifies, and in its neighborhood. CONSTITUTION:The two ends of each grid strip 3 are secured to a bow-shaped supporting member 1 by welding, etc., and the strips 3 are stretched over with a certain tension given by a spring load of a resilient supporting member 2. Therein the point where this spring load is applied to the bow-shaped supporting member 1, i.e., the junction of the two supporting members 2, 1, shall be located on the zero-moment axis 4. This eliminates tumble of the bow-shaped supporting member 1 when the strips 3 are set in stretching, and even though they are expanded thermally as the contrary case, the displacement ratio becomes uniform strip to strip. They are thus free from generation of slack. According to this constitution in which the mounting positions of the supporting members 1, 2 are set on the axis, where the moment of rotation generated by the tension of a number of strips 3 nullifies, and in its neighborhood, the difference in the stress change between different positions on the supporting member 1 is minimized, and the strips 3 can be prevented from slackening.

Inventor: TANJIYOU TAKEJI
IPC: H02J7/00
Filed: 1997-02-10
Abstract: PROBLEM TO BE SOLVED: To suppress lowering of capacity of a secondary battery by preventing lowering of capacity when the battery is left as it is. SOLUTION: The protector 1 comprises a section 2 for detecting the terminal voltage of a battery 9, a section 3 for detecting the battery temperature disposed closely to the battery 9, a discharge current detecting section 4, a control section 5 and a discharge section 8.

Title: Communication equipment
Inventor: NAKAJIMA MICHIO
IPC: H04L12/28
Filed: 1996-02-27
Abstract: PROBLEM TO BE SOLVED: To reduce the transmission failure in the case of re-transmission by dividing transmission data into two and sending again the data to a newly sat virtual path or a virtual channel and also to a virtual path or a virtual channel designated precedingly when transmission of the transmission data is failed. SOLUTION: A communication terminal equipment 11 at a transmitter side divides transmission data into cells and sends them to a master equipment 12. When a communication terminal equipment 11 at a receiver side detects a missing cell in the received data, the terminal equipment 11 sends information denoting failed transmission to the communication terminal equipment 11 at the transmitter side. Upon the receipt of the information, the terminal equipment 11 at the transmitter side sets newly a different virtual path(VP) or a virtual channel(VC) from the VP or the VC set for the preceding transmission and divides the transmission data and sends the resulting data to plural VPs or VCs including the newly set VP or VC. When the transmission is not yet successful, a VP or a VC is newly set again and the transmission data are divided again and the resulting data are set again.

IPC: G03G5/00
Filed: 1998-02-23
Abstract: PROBLEM TO BE SOLVED: To obtain an electrophotographic image forming member having resistance to the diminution of electric charges and dark attenuation by interposing an electric charge generating layer between a substrate and an electric charge transferring layer. SOLUTION: This electrophotographic image forming member has a substrate, an electric charge generating layer contg. photoconductive dye particles, a 1st film forming binder and 2,6-di-tert.-butyl-4-methylphenol and an electric charge transferring layer. The electric charge generating layer exists between the substrate and the electric charge transferring layer. The substrate may contain an electrically nonconductive or conductive material, e.g. a layer of an inorg. or org. compsn. A flexible resin such as polyester or polycarbonate in the form of a thin web may be used as the electrically nonconductive material. When the substrate is electrically conductive, it is not required to coat the substrate with an electrically conductive coating material. If the substrate is an electric insulator, it is usually coated with an electrically conductive layer.  The thickness of the electrically conductive layer may be varied in accordance with the degree of light transmission, etc., required by the electrostatic photographic member.

IPC: B41J2/375
Filed: 1988-02-23
Abstract: PURPOSE:To protect a thermal head by operating a protection circuit when an erroneous value is set to a counter circuit, by forming a current supply control signal by the counter circuit and providing a function for forcibly cutting the current supply control signal of a printing heat generator on the basis of the output of a comparing circuit for comparing the count value set to the counter circuit with a reference value. CONSTITUTION:When a count value is set by a counter setting signal 4, a current control signal 5 becomes logic '1' only for the time corresponding to the set count value and, at the same time, a comparing circuit 2 compares count output 6 with a reference value 7 and, when the count output 6 is smaller than the reference value 7, logic '1' is outputted to a current supply protecting signal 8. When the count output 6 is larger than the reference value 7, logic '0' is outputted to the current supply protective signal 8 and, therefore, an output thermal head current supply signal of an AND gate 3 forcibly becomes logic '0' and the driving of a thermal head is not performed.

Title: Semiconductor device wiring system
Inventor: SEKI MITSUO
IPC: H01L23/52
Filed: 1987-02-25
Abstract: PURPOSE:To increase wiring freedom and to reduce parts that are not wired, by performing wiring at different wiring layers without changing the running direction for a required length, thereafter changing the running direction in the wiring layers, alleviating the restrictions on the running directions of the wiring, and performing wiring. CONSTITUTION:The (y) coordinate of the line segment of a signal wiring, which is each wiring region, is determined for the (x) direction. At this time, on the line segment of another signal wiring in the (x) direction, wiring is performed on the different wiring layer but in the same direction. At this time, whether adverse effects are imparted on another signal or not is checked. When the result is not so bad, wiring is performed on the different wiring layer on the same route. This method is applied in the wiring region from the left end to the right end. When the right-end terminal is located on the upper side of the wiring region when the region is viewed from the left to the right, the line segment, whose wiring layer is changed, is overlapped on another signal wiring on the upper side as much as possible. When said terminal is located at the lower side of the wiring region, the segment is overlapped on another signal wiring on the lower side. In this way, the wiring layer grid of the line segment can be vacated, i. e., the wiring grid where the wiring has been located can be made vacant, Therefore, the freedom of the other signal wirings can be enhanced.
