Filed: 1987-12-09
Abstract: PURPOSE:To control parasitic motions between semiconductor substrates by forward direction motions, by forming a Schottky barrier diode as a diode in a reverse conductivity type region which is surrounded by isolated diffusion regions. CONSTITUTION:An N<+> type buried diffusion region 12 is provided by selective diffusion at a P-conductivity type semiconductor substrate 11 and an N-type epitaxial region 13 is formed on the above region 12.

Abstract: PURPOSE:To always stably output a stroboscope trigger signal even at the time of a high-speed shutter by outputting the stroboscope trigger signal for stroboscope emission by using a driving pulse to be generated from a device driving circuit. CONSTITUTION:When the luminance of a photographic scene is low and a stroboscope ON signal is sent to an AND circuit 28, an SSG 30 drives a counter simultaneously with the start of charge accumulation at a CCD 14 and when the second pulse of a horizontal synchronizing signal, namely, one horizontal period is defined as 1H, the stroboscope trigger signal is sent out to the input terminal of the AND circuit 28 just after the lapse of time shown by 2H like a second figure. Thus, a stroboscope control circuit 31 emits a stroboscope emission part 27 based on diaphragm value data inputted from a system controller 15 in advance. When a vertical synchronizing signal is outputted just after the lapse of charge accumulation time corresponding to shutter speed data, the charge accumulated in the photoelectric conversion part of the CCD 14 is read out by a sweep-out pulse and sent out to a preamplifier 24.

Title: Resin raw material for prepreg, production thereof and production of prepreg
Inventor: YOSHIZAWA MASANORI
IPC: B29B11/16
Filed: 1994-12-15
Abstract: PURPOSE: To obtain a resin raw material for a prepreg used as a matrix resin giving a prepreg reduced in stripelike defect or defect such as resin impregnation irregularity by setting an amt. of foreign matter at the time of filtering using a mesh metal net with a specific mesh size under atmospheric pressure to a specific value or less. CONSTITUTION: When a matrix resin is applied in a film like state by a coater, the resin is usually stagnated within a pot for a definite time but, when foreign matter is present, it is gradually grown. If foreign matter is present when a resin soln. passes through the slit of a coater, the filtering due to the slit is generated and not only the accumulation of foreign matter but also the growth thereof are generated to obstruct the flow of the resin emitted from the slit of the coater to generate a stripelike defect in a resin film. Then, the amt. of the foreign matter in a resin raw material for a prepreg at a time when the raw material is filtered under normal pressure by a #200 mesh metal net is set to 0.1g/kg or less. Further, filtering under normal pressure is performed in such a state that the resin raw material is held to temp. becoming liquid or dissolved in a solvent.

Title: Semiconductor memory device
Inventor: MIYASHITA KOJI
IPC: G11C11/413
Filed: 1995-11-30
Abstract: PROBLEM TO BE SOLVED: To embody the detection of the marginal defect of a semiconductor memory device in a short period of time. SOLUTION: A static random access memory has an address transition detection circuit 9 which detects the change in an address signal and generates a pulse A of a prescribed width and a pulse generating circuit which generates a pulse B for determining the activation period of memory cells by receiving this pulse A. The memory described above has a switching means for disconnecting the capacitance constituting an autopower down signal generating circuit 11 at the time of a test mode, thereby making the pulse width of the pulse B shorter by tc than the pulse width at the time of an ordinary mode. The setting of the severer timing condition is thereby made possible. Then, the detection of the marginal defect in the short period of time is made possible without using a test pattern.

Title: Sight examination apparatus
Inventor: TAKEUCHI TETSUJI
IPC: A61B3/028
Filed: 1987-12-10
Abstract: PURPOSE:To measure a visual field wherein an observer can visually confirm a target during visual work and to quantify the state of care on the basis of the magnitude of said range, by constituting the subject apparatus of a target providing part, an answer part for inputting the answer of the observer and an operation part for inputting the signals from both of a setting part and the answer part to allow the observer to calculate the visual field range capable of visually confirming the target. CONSTITUTION:A target providing part 3 inputs the signal from a setting part 2 and provides a target at the position of the visual field corresponding to said signal. An answer part 4 outputs the signal corresponding to an answer result showing whether an observer can visually confirm the provided target. An operation part 5 inputs the signals from both of the setting part 2 and the answer part 4 to calculate the area of a visual field range capable of visually confirming the target from the relation between the target providing position and the answer result and outputs the signal corresponding to the reciprocal thereof. In this case, since the visual field range capable of visually confirming the target becomes narrow as the degree of the concentration of care to one point becomes high, said reciprocal corresponds to the state of care. A display part 6 inputs the signal from the operation part 5 to display the value corresponding to the state of care. By this method, the state of care during visual work can be quantitatively calculated.
