Title: System timing synchronizing system
Inventor: TSUSHIMA HITOSHI
IPC: H04L12/00
Filed: 1984-03-03
Abstract: PURPOSE:To suppress the establishment of transition of a master station and also to simplify the transition means by transmitting independently a master packet and a data packet. CONSTITUTION:The master packet A.M transmitted from a station A exists in the 1st block of a frame F(n) and the system timing of each station is synchronized by the packet. Further a data packet B.D of a station B and a data packet C.D of a station C exist in the 2nd block. When the master packet A.M is lost in a frame F(n+1), the station B detects it and transmits a master packet B.M to the 1st block of a frame F(n+2) while it is discriminated that the own station is under the condition to transmit the master packet. Moreover, the timing of the frame F(n) is kept in the frame F(n+1) and reset by the master packet B.M.

Title: Operational amplifier with phase compensation function
Inventor: NAGATA MINORU
IPC: H03F1/42
Filed: 1989-02-23
Abstract: PURPOSE:To expand the effective amplification band of an operational amplifier over a frequency of a 2nd pole by using one capacitor for compensating a major pole and for compensating feedforward. CONSTITUTION:An output of a feedforward compensating amplifier 14 is connected to a DC potential section 16 via a resistor 17 and connects to an active load circuit via a compensation capacitor 18. As the frequency of an input signal is gradually increased, the frequency characteristic curve is gradually decreased from a frequency (major pole), and the major pole is set by a loop comprising the capacitor 18 and the resistor 17. Then the capacitor 18 and the resistor 17 apply compensation effect to the output of a current output amplifier 15 from the low frequency up to the vicinity of the 2nd pole and act like compensating a feedforward compensation amplifier 14 at a frequency higher than the 2nd pole. Thus, the effective amplification hand of the operational amplifier is extended over the 2nd pole frequency.

Abstract: PURPOSE:To improve image quality by interposing a stripping tape between a copying paper which is electrostatically attracted to a photoreceptor and a photoreceptor, piercing a through-hole in the stripping tape of the part makig slidig contact with the photoreceptor, inserting an auxiliary roller in this through-hole and grasping the end part of the copying paper. CONSTITUTION:Copying paper (p) is guided to a photoreceptor 1 and is electrostatically attracted thereto. At this time one end part of the copying paper (p) is grasped and conveyed by an auxiliary roller 9 and the photoreceptor 1. Hence, even in the high moisture where electrostatic attraction force of the photoreceptor 1 to the copying paper (p) is weak, it turns out that the copying paper (p) is surely attracted to the photoreceptor 1 by the auxiliary roller 9. At this time, a transfer device 2 makes corona charging and transfers the original image formed on the photoreceptor 1 to the transfer paper (p). Along with the rotation of the photoreceptor 1, the copying paper (p) is stripped along a stripping tape 3, and glides on guide wires 4. It is grasped by conveying rollers 5, 5 from the leading end part and is thereby conveyed.

Filed: 1980-03-31
Abstract: PURPOSE: To manufacture a very slender thin-walled tube having a large inside/ outside diameter ratio by heating a glass tube with one end sealed while applying a predetermined pressure to the interior of the tube and drawing the heated tube.

Abstract: PURPOSE:To accurately detect an abnormality caused from a partial discharge generating without synchronizing to the voltage synchronization in an electric equipment by deciding a start time of sampling with an electrical signal of the partial discharge generated from the electric equipment inside. CONSTITUTION:A heat current in a container 1, which is caused by the partial discharge generating with an insulation deterioration, etc., around a conductor in the conductive container 1 impressed with a high voltage, is detected by a thermal conductivity sensor 4.

By the command part 9, the level of a signal S4 inputted from a filter 12 and a threshold level are compared, and the sampling command signal S5 is generated when the signal S4 with level larger than the threshold level is inputted. Next, a sampling for the frequency components of the heat current generated from the container 1 is started by a sampling part 6 to perform many samplings, then a decision for the inside abnormality can be made by means of cumulatively adding the sampling data by an arithmetic part 7.

IPC: G06T7/00
Filed: 1995-03-01
Abstract: PURPOSE: To generate an accurate model with less operation and smaller data quantity by designating remarked points on pictures to be remarked by the use of plural cameras, designating the stereoscopic shape of an object and calculating their vertex coordinates. CONSTITUTION: In respect of the three-dimensional position of some point on the object 1, a point on camera pictures taken by, for instance, two cameras C0, C1 at different positions (points by two cameras to conform with each other in three-dimensional space: remarked point) is designated. This remarked point is made (Uc0 , Vc0 ) on the picture of the camera C0 and (Uc1 , Vc1 ) on the picture of the camera C1. Then, by calculating the equations of straight lines which pass through the origins 0 of the cameras C0, C1 and have direction vectors (ac0 , bc0 , cc0 ), (ac1 , bc1 , cc1 ) so as to be free from the error, the three- dimensional position of the point at which these two straight lines intersect each other becomes the three-dimensional position of the remarked point.  At that time, the point at which distance between two straight lines becomes minimum is calculated, and this point is made the three-dimensional coordinates of the remarked point. As the result, the point most approximate to an intersection can be obtained.

Title: Relief image for black matrix substrate
Inventor: MITAMURA SATOSHI
IPC: G02B5/20
Filed: 1993-03-03
Abstract: PURPOSE:To produce a black matrix substrate having high dimensional accuracy and excellent light shieldability by electroless plating at a low cost by incorporating polyvinyl alcohol(PVA) having a specific X-ray scattering intensity into the substrate and having black matrix patterns. CONSTITUTION:This black matrix substrate contains the PVA having 200 to 580cps/mum X-ray scattering intensity determined by the X-ray diffraction method and has the patterns for the black matrix. Since the PVA has 200 to 58Ocps/mum X-ray scattering intensity, an electroless plating liquid eventually penetrates uniformly and rapidly into the relief image when the electroless plating liquid comes into contact with the relief image. Metallic particulates are thus approximately uniformly and rapidly precipitated over the entire part of the relief. The production of the relief image 4 is executed by forming a photosensitive resist layer 3 on a transparent substrate 13 and exposing and developing the photosensitive resist layer 3 via a photomask 9 for the black matrix.
