Title: Semiconductor memory
Inventor: MATSUMURA TSUNEO
IPC: G11C29/00
Filed: 1982-02-08
Abstract: PURPOSE:To reduce the increment of number of refresh divisions below an amount equivalent to number of spare word lines, by driving simultaneously the sense/refresh amplifiers of all memory blocks via an address converting circuit. CONSTITUTION:A high-level output that is delivered via an address switching circuit 8, an address buffer 7, etc. at every refresh cycle is converted through converting circuits 12 and 12 via refresh row decoders 11 and 11' for every memory block. With output of this conversion the sense/refresh amplifier trains 3 at every memory block formed with a main body memory cell array 1 and a spare memory cell array 2 are driven at one time. One of N pieces of word lines and one of n pieces of spare word lines at every memory block are selected at one time to perform refresh. Therefore the increment of number of refresh divisions can be set less than n pieces of spare words in comparison with number of refresh divisions of a semiconductor memory which has no constitution of a redundant circuit. This can prevent a large increment of number of divisions.

Title: Method and device for adjusting ac input signal
Inventor: POORU BIII PATSUTON
IPC: F23N5/20
Filed: 1990-01-26
Abstract: PURPOSE:To suppress the number of allowable noises by discriminating the existence of an AC input signal by sampling for plural times with the periodical half cycle of an AC system signal, and generating a result signal representing the existence of the AC input signal when a large number of AC input signals are counted. CONSTITUTION:The phase of the AC system signal is synchronized essentially with that of the AC input signal 16, and the AC input signal 16 is sampled for plural times, and it is discriminated whether or not is exists within the half cycle period of the AC system signal. A result value representing the state of the AC input signal is decided by the signal with higher sampling times. Thereby, reliability for the AC input signal can be improved, and since the AC input signal is separated optically from a logical signal used by a control part 22 in a control system 10, a transient voltage is suppressed, and the logic circuit element of the control system 10 can be protected from a voltage spike. Also, since the AC input signal appears only in the positive period of an AC line voltage, an optical separator 18 can be tested in the negative period of the AC line voltage, and safety and the reliability for an optical separation circuit can be secured.

IPC: G06T11/40
Filed: 1987-01-28
Abstract: PURPOSE:To shorten the picture drawing time by providing a frame memory for control to perform the writing control of held data. CONSTITUTION:A picture drawing frame memory 1 has the capacity corresponding to all pixels of a display 5 and a control memory 2 has the same constitution as the memory 1. The data on a relevant color is written only to a color changing point into the memory 1 in the direction X. While the data showing a color changing point is written into the memory 2 at a position corresponding to the relevant color changing point. When a paint-out display is given on a display 5, the memory 1 is read and this data on the memory 1 is held until the color changes next in the direction X. The color changing control of the direction X is carried out by reading the memory 2. As a result, the picture drawing time is extremely shortened.

Title: Sheet supporting apparatus of sheet forming machine
Inventor: ASANO KAZUO
IPC: B29C48/08
Filed: 1981-02-10
Abstract: PURPOSE:To form a sheet uniformly, by blowing pressurized air from blowing holes provided in a lower mold against the sheet undersurface thereby at the time when the sheet is being fed or during the mold clamping operation the resin sheet would not sag so that the thickness of the sheet would be prevented from being ununiformed. CONSTITUTION:The heat-softened resin sheet (a) is fed between the lower mold 15 and an upper mold 14 of the forming machine 11 with the edges of the sheet clamped. Against the undersurface of the sheet is blown air under pressure that is supplied to the lower mold via a check valve 37 from a horizontal position supporting blower 36 and is jetted from the pressurized air blowing holes provided in the lower mold, so that the sheet is prevented from sagging and is supported horizontally. The sheet is kept horizontally during the feeding of the heat-softened resin sheet, at the time when the sheet is stopped over the lower mold and during the clamping operation of the upper and lower molds, so that uneven thickness of the sheet due to sagging of the center of the sheet would not occur, and the blowing of the air and stopping of the air are effected by the operation of the valve to make the thickness of the sheet uniform.

Abstract: PURPOSE:To make it possible to arrange a conductor for electromagnetic shield in the vicinity of a toroidal type coil and yet to give a thin type electromagnetic shielding function to it, by forming such a type of coil having a rectangular cross section in a multilayer circuit substrate. CONSTITUTION:Nos.1-4 conductive layers 1A, 1B, 1C, 1D are to be set up in the multilayer circuit substrate, in each among which an insulation layer 2 is to be interplaced. The radial conductors 3A-3J are formed on No.2 conductive layer 1B, while the same 4A-4G on No.3 conductive layer 1C. Between the thru- holes (5A, 5C, 5E, etc.,) and (5B, 5D, 5F, etc.,), respectively, the beginning and ending points of each radial conductor formed on the Nos.2 and 3 conductive layers are electrically connected to each other. Forming the thin toroidal type coil as mentioned above can confine the main magnetic flux generated by a current running through the coil into both the insulation layer 2 between the Nos.2 and 3 conductive layers 1B, 1C and its nearby insulation layer portion. Even arranging a conductive layer for electromagnetic shield in the vicinity of the coil results in hardly influencing the coil.
