Patent JP-H0527600-A (JP)
Title: Magnet device
Inventor: IWAI MASAHARU
IPC: G03G15/09
Filed: 1991-07-18
Abstract: PURPOSE:To obtain the magnet device which obviates the generation of unequal development, etc., and has excellent durability by using a magnetic material, such as iron, as the blank material of a sleeve. CONSTITUTION:The sleeve S of a magnet roll M which is magnetized to multiple poles on its surface and is rotatably fitted externally with the cylindrical sleeve S is produced from the inexpensive magnetic blank material. For example, iron, etc., which are inexpensive, are easily workable, and have the surface hardness higher than the surface hardness of aluminum, etc., are usable as the magnetic material. The iron is inexpensive and has the higher surface hardness than the surface hardness of the aluminum and is, therefore, an optimum material. Since the iron has the excellent workability, the production of a seamless pipe is easy and the sleeve having no seams on the surface is easily obtd. The sleeve made of the magnetic blank material is stronger in the magnetic field distribution generated on the sleeve surface than the sleeve made of a nonmagnetic blank material, but such increase in the magnetic field distribution is dealt with by weakening the magnetic force of the magnet roll M to be housed in the sleeve S.

Title: Manufacture of resin molding
Inventor: FUJIOKA HISASHI
IPC: B29C45/16
Filed: 1990-07-31
Abstract: PURPOSE:To make it possible to obtain a resin molding, the color tone of the terminal side of which is kept at the desired tone, by a method wherein material different in color is located at the central side of the resin molding from the at its peripheral part and further the direction of resin flow at the terminal part is regulated. CONSTITUTION:Excluding the opening position of a gate 15, through which synthetic resin E is injected in the cavity space 16 of molds 13a and 13b, an extension space 18, which extends outwards from the peripheral surface part of the cavity space 16 through a communicating hole 17. From the gate 15 of the molds 13a and 13b into the cavity space 16, the synthetic resin E containing material P, which has the color different from that of the light- colored synthetic resin E And is surrounded by the synthetic resin E so as to locate at the central side, is injected and filled.

Title: Automatic gain control circuit
Inventor: UCHIKURA HIDEAKI
IPC: G11B20/10
Filed: 1984-09-28
Abstract: PURPOSE:To detect position information rocorded in a specific section with accuracy by providing an analog switch between an amplitude detector and integrator, interrupting an AGC loop only in the specific section and holding gains controlled by previous information. CONSTITUTION:An analog switch 47 is controlled by the control signal from an input terminal 50, and closed when a signal 58 is at a high level. However, since position information 53 and position information 54 are inputted after prescribed period since a position information start signal 52 was detected, an analog switch control signal 58 is set at a low level for a period 57 for covering sufficiently sections 55 and 56, and the analog switch 57 is opened. This type of analog switch control signal can be generated by a simple timing circuit. When the analog switch 47 is opened, the charge of a capacitor 48 holds the potential just before the analog switch 47 is opened, because a charging/discharging route is cut off. As a result, the gain fluctuation will not occur in the period 57 even if an input signal amplitude becomes minimal, and position information can be outputted to an output terminal 43 without errors.

Title: Hourglass with alarm
Inventor: ISOBE YASUO
IPC: G04F1/06
Filed: 1981-12-17
Abstract: PURPOSE:To enable even visually handicapped person to use a sandglass eliminating minitoring by measuring time depending on a warning appealing to a sense of vision, hearing, touch or smell given as soon as the whole or a part of sand or the like at the upper portion falls down completely to the lower portion via a reduced part. CONSTITUTION:No signal transmitted from a signal transmitting point 7 reaches a signal receiving point 8 blocked by sand 4 or the like until all of the sand 4 or the like falls down completely to the lower portion 3 from the upper portion 1 via a reduced part 2. In other words, the signal receiving point 8 is opened electrically. As the signal receiving point 8 is opened while a main switch 10 is closed, a warning device, a buzzer 6, won't work. When all of the sand 4 or the like at the upper portion 1 has fallen down to the lower portion 3 via the reduced part 2, the signal transmitted from the signal transmitting point 7 reaches the signal receiving point 8 as there is nothing blocking the signal. In short, the signal receiving point 8 is closed electrically and with the main switch 10 closed, the warning device, the buzzer 6, works. This allows any person to measure time by hearing the warning sound.

Filed: 1987-08-17
Abstract: PURPOSE:To reduce the wiring for clamping in a wiring region to the utmost, and exclude an obstacle to the connection of general signals in automatic wiring design, by providing a common clamping signal wiring for clamping voltage which is independent of individual type pattern. CONSTITUTION:A clamping signal wiring 106 is one in which a wiring to clamp a logic value '1' is arranged in a wiring region 105 between logic cell raws 104, as a common pattern independent of types. Therefore, gate groups 108 requiring to clamp the logic value '1' can obtain a specified input voltage by connecting their inputs to the clamping signal wiring 106, and signal wirings for that purpose can be reduced to a minimum. Further, by arranging a clamping voltage generating circuit outside the cell raw region, cells for clamping which are arranged everywhere in the prior art are unnecessitated. Thereby, at the time of performing an automatic wiring design applying a computer, the connection of general signals is effectively enabled.
