Title: Meissner effect confirmation device
Inventor: ITO MASAATSU
IPC: G09B23/18
Filed: 1996-01-19
Abstract: PROBLEM TO BE SOLVED: To provide the device through which Meissner effect can be confirmed in safety. SOLUTION: This device is equipped with a low-temperature cooling means 7, a superconductor which is cooled by this low-temperature cooling means 7, and a vacuum chamber 7 which covers the superconductor 3 to insulate it from the head of outside air. The low-temperature cooling means is not exposed to the outside at all, so extremely high safety is obtained. The vacuum chamber is held in a nearly vacuum state and consists of a vacuum layer as a principal heat insulating element and a material which is transparent and hard and easily transmit lines of magnetic forces may be used for a shield wall for the outside air. The superconductor 2 can visually be confirmed from outside, so this is suitably used for experimentation of educational fields and demonstrations at various places.

Title: Clock extract circuit
Inventor: HARA KENJI
IPC: H04L25/49
Filed: 1995-01-20
Abstract: PURPOSE: To attain synchronization with a data pattern of any Manchester code by providing a logic circuit which stops the count at an upper limit and a lower limit of a counter and provides an output of a prescribed down-count and up-count so as to reduce number of components. CONSTITUTION: A counter 3 counts number of clock pulses Cp by using data 0 or 1 being a received Manchester code signal as an up/down switching signal. When the count reaches an upper limit/lower limit of the counter 3, the count is stopped and when the count is incremented by four from the lower limit 0 and the count is decremented by four from the upper limit 16, an output from an AND circuit 7 is an extracted clock signal. The clock signal obtained in this way is fed to a D flip-flop 8, then the received Manchester code signal is demodulated into an original data signal.

Title: Xy address type display device
Inventor: KARAKAMA SHUNSAKU
IPC: G02F1/133
Filed: 1997-01-20
Abstract: PROBLEM TO BE SOLVED: To prevent delays from being generated due to signal delays in timing when pixels formed at positions separated from a Y driver become display states by making the constitution of a switching transistor so that the farther the separation from the Y driver is, the larger the value of channel width/ channel length becomes. SOLUTION: Thin film transistors 2 are made so that the layer transistors whose values of channel width/channel length are, the more they are separated from the Y driver. That is, respective transistors to be connected to Y direction lines 4a∼4c are set so that, in the case of the line 3a of X direction lines 3, channel lengths of them are the same and channel widths of them successively become larger the more they are separated from the Y driver 6. Since the thin film transistors 2 are made so that values of the channel width/channel length of transistors of pixels are larger the more thr transistors of the pixels are separated from the Y driver 6, delays of timings becoming display states due to signal delays to be generated in gate lines of the thin film transistors 2 can be supplemented.

Inventor: GOTO KATSUMI
IPC: G11B5/027
Filed: 1995-01-20
Abstract: PURPOSE: To avoid the significant decline of the reproducing output of a following head when the recording is simultaneously performed by a leading head and the following head which are provided closely to each other. CONSTITUTION: A rotary drum 2 which rotates in a required direction and a leading head 1a and a following head 1b which are provided on the rotary drum 2 closely to each other and by which at least data are recorded on a magnetic tape are provided. When the data are recorded practically simultaneously by the leading head 1a and a following head 1b, the width of a second track which is formed on the magnetic tape by utilizing the following head 1b is made to be practically larger than the width of a first track which is formed by utilizing the leading head 1a. If the data are recorded by the two heads provided closely to each other simultaneously, the track which is recorded by the following head is narrowed.  However, with this constitution, as the width of the said track is made to be large from the first, even if the width is narrowed, the sufficient reproducing output can be obtained.

Title: Recording device for electrophotography
Inventor: MITSUYA TERUAKI
IPC: G03G15/00
Filed: 1986-01-20
Abstract: PURPOSE:To reduce an irregularity in the density of an image after fixation and variation in density with the number of prints by making variation in fixed image density much less than variation in unfixed image density. CONSTITUTION:Optical reflection density in an unfixed state before heating is set to d1*=1.31 based on the maximum value d2*=1.26 of fixed image density. At this time, d1=d1 in the range of the resolution of the optical reflection density and the unfixed image density of a recording device is normal reflected density and varies to variation width of about 0.2-0.3. If the unfixed image density varies to variation width d1H-d1L=0.28 of d1L=1.17-d1H=1.45 while d1=1.31 is the maximum degree, the variation width of fixed image density is a=0.02. It is said that the variation width of the print image density of a conventional recording device is about 0.1-0.15 as optical reflection density and the minimum value of optical reflection density difference which can be discriminated by a human being is 0.02. Therefore, variation width of the fixed image density is extremely small.

A first comparison means compares the detection pattern with a known pattern to locate the detect in the substrate 2. Subsequently, a second comparison means compares the differentiated data of detection pattern with a known pattern to locate the detect in the substrate 2.

Abstract: PURPOSE:To form a fine pattern with sufficiently high accuracy even if a step exists on its surface by projecting to expose a plurality of positions on the relatively different optical axes of a mask pattern focused surface and a resist film, and photosensing the resist only by exposing at near relative positions. CONSTITUTION:A plurality of positions on the different optical axes of a mask pattern focused surface and a resist film are projected to be exposed, and a resist is selectively photosensed only by the exposure at the near relative positions of the focused surface and the resist film face. For example, a photoresist layer 2 is formed on a substrate 1 having a step on its surface, and a light transmissible selective film 3 which has properties to be opaque to an exposed light at the time of unexposure and transparent upon irradiation of the exposed light and returns to an opaque film upon interruption of the exposed light is formed. The pattern is exposed by a projecting exposure device, and then developed to form a resist pattern 4. In this exposure, first exposure is conducted by bringing the focused surface to the protruded surface 1' of the substrate 1, and second exposure is conducted by then bringing the focused surface to the recess surface 1'' of the substrate 1.
