Title: Fault detecting system
Inventor: AKAO TAKASHI
IPC: H04L12/26
Filed: 1984-02-20
Abstract: PURPOSE:To improve the reliability of a communication equipment by allowing a master set to detect a check pattern transmitted from each slave set to attain quick and simple detection of a fault. CONSTITUTION:The master set 1 generates a packet P0 from a packet analysis generating section 6 at each predetermined time and transmits it to a channel 3-0. When a slave set 2-1 identifies a packet P0 from the master set 1 by using a reception section 4, a packet P1 added with a check pattern specific to the own set 2-1 is generated by the packet analysis generating section 6 and transmits it to a channel 3-1. A packet Pn is generated from a slave set 2-n of the final order similarly successively and the result is transmitted to the master set 1. The packet analysis generating section 6 of the master set 1 analyzes the arriving packets P1-Pn and an error generated in the slave sets 2-1-2-n is detected immediately while being separated into the transmission side and the reception side depending on the error of the check pattern included in the packet P1-Pn.

Filed: 1987-02-12
Abstract: PURPOSE:To reduce the polling period by providing a polling address table and an address pointer to a host device so as to limit the reference of a terminal device state table for the required reference only. CONSTITUTION:An address pointer 21 has an stepping means 22 to address a polling address table 23.

Title: Current source
Inventor: HENDORIKUSU YOHANESU SUHOOUENA
IPC: H03M1/00
Filed: 1989-02-13
Abstract: PURPOSE: To match the output current of a current source with a predetermined binary weighted value most accurately by configuring each current source with current source transistors(TR) which are decentralized as equally as possible covering the surface area of an integrated circuit. CONSTITUTION: The respective bases of TRs T1 to T10 in the form of a binary weighted series of parallel TRs are connected to one another, and the respective emitters are connected to a common point applied with a current Iin . Further, the collectors of the TRs T1 and T10 constitute output terminals of the current source device. Then the current Iin is dispersed covering the TRs T1 to T10 at the rates of their emitter surfaces so that the collector currents of the TRs T1 to T10 are at rates in a binary weighted series of currents I, 2I...256I, 512I. Therefore, a temperature gradient, and a gradient and variation like impurity concentration variation generated in the device are dispersed as equally as possible covering the respective current sources, so the binary ratio of the current sources becomes higher in precision, thereby reducing the danger of monotonous error production.

Title: Prevention equipment against lateral vibration of building
Inventor: SAITO SHIGENOBU
IPC: E04H9/02
Filed: 1989-02-10
Abstract: PURPOSE:To attenuate lateral vibration with an action of a restoring force due to the inertia of a top on a structure, by giving the top a large angular momentum, which is provided at the upper part of a building and supported to be freely rotatable around a vertical spindle and also rotated with a high speed on an earthquake. CONSTITUTION:A spin shaft 5 fixed with a cylindrical rotor 9 is supported to be freely rotatable at the uppermost part of a building 2 and connected to a rotary driving equipment 10. Next, an earthquake sensor 13 is buried via a signal cable 14 in the underground of the building 2 and designed to immediately input the signal on an earthquake into a control 12. A top 5 rotates usually with a low speed by the rotary driving equipment 10, but when the earthquake sensor 13 detects an initial fine move of an earthquake, the signal is input into the controller 12 to rotate the top with a high speed and give a large angular momentum. Thereby, lateral vibration of the building 2 is attenuated effectively with the action of the storing force of the spin shaft 5.

IPC: G21C7/16
Filed: 1988-02-16
Abstract: PURPOSE:To prevent damage of a spring by covering the circumference of a float and the spring with a windshield cylinder. CONSTITUTION:The windshield cylinder 50 is installed around the float 43 and the spring 44. A ring 51 which is large in diameter and is provided with plural pieces of water flow holes 52 is used. The part near the bottom end of the windshield cylinder 50 is fixed to the outside circumference of the ring 51. Further, a gap G for gas venting is formed between the top end of the windshield cylinder 50 and a body 40. The flow of gas is shut off by the windshield cylinder 50 and the exertion of rotating force on the float 43 and the spring 44 is prevented even if the gas is rapidly released from an accumulator device at the time of a regular inspection if the level switch is constituted in such a manner. The damage of the spring is thus prevented.

Filed: 1980-03-13
Abstract: PURPOSE:To improve durability and reliability without affected by contamination and damage by specifying peripheral length of a photoreceptor drum to that of a transfer drum in integer proportion and by separating the drums while no-picture areas of both the drums are made to agree as the drums rotate. CONSTITUTION:The radiuses of photoreceptor drum 10 and transfer drum 17 and arc lengths of their no-picture areas are equalized. Therefore, when the drums rotate by engaging with gears, those areas agree mutually all the time. At both ends of the outer circumferential parts of drum 17, flanges 44 and 45 are arranged and the end part of flange 45 is made into gear 48, which engages with gear 49 of drum 10. Both the gears have the same pitch circles and modules. To the no-picture area of drum 17, spacer 50 is fixed and transfer paper clampers 51 are arranged in the generating line direction and opens and closes from and to the circumferential surface of the drum synchronizing with the rotation position. Cover 55 has the same curved surface with the external circumferentail surface of drum 10 and is arranged at a position a little bit lower than the external circumferential surface. When the no-picture part areas agree through the rotations of the drums, the drums are contact-separated each other by spacer 50.

Title: Apparatus for inspecting index of refraction of lens
Inventor: SUHARA HIROYUKI
IPC: G01M11/02
Filed: 1995-02-21
Abstract: PURPOSE: To inspect an index of refraction in a nondestructive manner by setting between a collimating optical system and an image-forming optical system a cell filled with a liquid of an index of refraction nearly equal to that of a lens to be inspected, and detecting a difference of image-forming distances between when the lens is inserted in the cell and when the lens is not inserted in the cell. CONSTITUTION: The light from a light source 10 is turned to parallel light beams by a collimating optical system 11. An image-forming optical system 14 forms an image by the parallel light beams passing through a cell 12 filled with a matching liquid 13. The using matching liquid 13 has an index of refraction nearly equal to that of a lens 15 to be inspected. A double knife edge 20 is set to hold an image-forming position of the optical system 14 between knife edges 20a and 20b. An image-forming position detection part 24 detects a peak value of outputs of a photodetecting element 23. When the peak value of the edge 20a is larger than that of the edge 20b, the edge 20 is moved left by a stage 22 to make the peak values equal. Tone position is recorded.  When the lens 15 is inserted in the cell 12, if the index of refraction is the same as that of the matching liquid 13, the image-forming position is not changed. However, if the index of refraction of the lens 15 is different from that of the matching liquid 13, the image-forming position is changed. The detecting part 24 outputs the difference and obtains the index of refraction of the lens.

When the current Iin is so set that I4/I7=I0 is true, the temperature coefficient of the output is 0.2mV/C in accordance with the diode equation. If the magnitude and the direction of the current min are set in this manner, the temperature coefficient can be properly adjusted to cancel the temperature drift.
