Abstract: PROBLEM TO BE SOLVED: To provide an alkaline storage battery using a metal porous substance as an active material holder and free of generation of internal shortcircuit even if a band-shaped metal plate is attached to the active material holder and wound into a spiral form. SOLUTION: A band-shaped metal plate 10 is continuously attached to an active material unfilled portion 22 at the end in the longitudinal direction of an active material holder 21 of a nickel positive electrode 20, and winding is made so that the boundary between the band-shaped metal plate 10 and an active material filled part is positioned opposing to a negative electrode and the band-shaped metal plate 10 lies outside the spiral. Accordingly the unfilled portion 22 of the active material holder 21 lying inside the spiral will not exfoliate from the band-shaped metal plate 10, and out-facing burrs of the spiral will not be generated in the portion 22.

Title: Semiconductor device
Inventor: ITO KENJI
IPC: H01L21/3065
Filed: 1998-03-19
Abstract: PROBLEM TO BE SOLVED: To precisely detect a part where a wiring is corrected and a cross section form is observed, by providing a mark pattern where the uppermost layer wiring is constituted of a plurality of forms. SOLUTION: In a semiconductor device, a lower layer wiring 1, a circuit 70 and a circuit 80 are connected. When the circuit 70 and the circuit 80 are opened, and the circuit 80 and a circuit 90 are connected for improving a characteristic, marks 21-28 are simultaneously formed at the time of forming the uppermost layer wiring 2. Thus, the uppermost layer wiring 2 and the marks 21-28 can be observed in an FIB device. The cut point 33 of the lower layer wiring 1, and the connection points 31 and 32 of the lower layer wiring 1 can be decided with the marks 21-28 as reference points. Thus, a laser beam is abutted on the cut point 33 and an interlayer insulating film on the lower layer wiring 1 is removed. Then, the lower layer wiring 1 of the cut point 33 is removed/disconnected. Thus, it can be discriminated in how many numbered layer the wiring layer becoming an object where the wiring is corrected and a cross section form is observed exists and a place in a chip can also precisely be decided.

Abstract: PURPOSE:To prevent the generation of parasitic MOS effect in the semiconductor device by a method wherein the other conductive type region formed in a one conductive type substrate is surrounded with the one conductive type highly concentrated regions and other conductive type regions or wiring layers connected to the one conductive type highly concentrated regions. CONSTITUTION:For example, in the structure being provided with the reversely biased P type regions 11, 13 in the N type substrate 17, and being arranged with an Al wiring 14 between those regions interposing an insulating film between them, the highly concentrated N type regions 12 are provided as channel blocking layers on both sides of the P type region 11.

Abstract: PURPOSE:To shorten the indexing cycle time by constructing an automatic indexing device such that a central value in an angular section where the rotary angle of a drill and the output information from an optical sensor are first output signals is calculated as an indexing angle, and the drill is positioned with that indexing angle. CONSTITUTION:A drill 16 is mounted on a spindle 11 then a servo motor 13 is driven to bring the drill 16 into constant speed driving condition, then an optical sensor 17 is functioned. Light is projected from a light emitting section at the tip section 18 of the optical sensor 17, and receiving quantity of light is measured at a light receiving section. On the other hand, output from a rotary encoder 14 fixed to the servo motor 13 is inputted to a controller 19 and stored in a memory. Then the controller 19 calculates the central value in an angular section where first output signal is provided when the quantity of light being received by the optical sensor 17 is small as an indexing angle, then controls the servo motor 13 and positions the servo motor 13 with that indexing angle. Consequently, operation can be made easily in short time when compared with an image processor.

Filed: 1980-05-29
Abstract: PURPOSE:To prevent the performance of development from deteriorating owing to the granulation of toner by detecting the density of the toner by light with a wavelength longer than the grain size of the toner. CONSTITUTION:A developing solution 12 from a container 13 is sucked up by a pump 14 to a vessel 16 and then returns to the container 13 via the hole 17 of the container 16. The container 16 is provided with a light source 18 and a photodetector 19 facing mutually across the developing solution. The light source 18 and photodetector 19 detect toner density with light with a wavelength longer than the grain size of the toner; for example, a light souce emitting only light with a wavelength longer than the grain size of the toner and an ordinary photodetector are  used in combination. As a result of the detection of the toner density, if a detection varies owing to the granulation of the toner, a toner supplementing mechanism is driven according to the output signal to supplement the toner to the developing solution 12. Thus, the deterioration of the performance of development due to the granulation of the toner is prevented.
