Abstract: PURPOSE:To execute distance measuring operation with high accuracy, and also to eliminate the waste of a distance measuring operation time by providing an offset correcting circuit for suppressing an integral output of the time to a prescribed value or below, on an integration circuit when the light for distance measurement is not emitted yet. CONSTITUTION:An offset correcting logic 321 generates correcting signals 302a, 302b from three signals of output LL, HH and AB of a comparing circuit constituted of 104-107. The correcting signals 302a, 302b are applied through fixed resistances 309a, b to inputs of operational amplifiers 304a, b of a high input impedance. A variation of output voltages of 304a, b, namely, correcting voltages 303a, b is determined by the fixed resistances 309a, b, capacitors 306a, b, and an applied voltage and an applied time of the correcting signals 302a, b. Accordingly, by controlling the polarity of the applied voltage and the applied time, this output voltage, namely, correcting voltages 303a, b can be set optionally. The correcting voltages 303a, b are applied to inputs of integration circuits 103a, b, namely negative input terminals of operational amplifiers 208a, b through fixed resistances 305a, b, and a correcting current proportional to the voltage is made to flow.

Title: Optical fiber unit and its production
Inventor: SAKABE ITARU
IPC: G02B6/44
Filed: 1997-02-20
Abstract: PROBLEM TO BE SOLVED: To make it possible to easily provide a sheath which is hardly breakable and to make mass smaller when this optical fiber unit is of the same outside diameter as an optical fiber unit not provided with this sheath and has the same rigidity by making the outermost layer to low-foaming or non- foaming. SOLUTION: For example, 7 pieces of optical fibers 1 are used and are stranded or are bundled without stranding these fibers. The bundle formed in such a manner is coated thereon with a primary coating layer 2. For example, optical fibers coated with a UV curing resin of 0.25mm in outside diameter are used as the optical fibers 1. The primary coating layer 2 is the foaming layer of foamed polyethylene(PE), etc. The secondary coating layer 3 applied on the primary coating layer 2 is a layer of lower foaming than the foaming layer of the primary coating layer or a non-foaming layer is used for the same. For example, the low-foaming or non-foaming PE is used. The low-foaming is determined from the degree at which the sheath hardly receives external flaws and buckling. The low-foaming is thus a foaming rate of <=40%, more preferably <=30%.  As a result, the surface is made smooth and marked characters and symbols are made easier to read.

IPC: B65G39/02
Filed: 1984-02-28
Abstract: PURPOSE:To increase the allowable load and transport amount of a cup of a conveying transfer pole of a storehouse or the like by supporting a cap on an elastic spacer. CONSTITUTION:When a transported article moves on a steel ball 15, the steel ball 15 is rotated with the movement of the transported article. In this case, as the steel ball 15 is supported by small-diameter steel balls 14, the steel ball 15 can be smoothly rotated with small frictional resistance. The stress applied to a cup 13 by load of the transported article passing on the steel ball 15 is supported by an elastic spacer 16 and uniformly dispersed to the entire lower surface. This arrangement can increase the allowable load of the cup and the transport amount.

Abstract: PURPOSE: To subject a perforated rotary barrel to a polishing operation for a long period of time by rotating the barrel in a compound solution-containing polishing vessel, and transferring the barrel to another vessel to be subjected to post-polishing treatment.  
     CONSTITUTION: A motor 10 is driven to move a polishing vessel 4 above a polishing vessel 4. A motor 24 is driven to lower lift plates 30a, 30b via chains. Thus, a perforated rotary barrel 14 suspended from the carriage 8 is rotated in the polishing vessel 4 to polish materials in the barrel 14. After a polishing operation has been finished, the lift plates 30a, 30b are raised to transfer the carriage 8 to a washing vessel 5, a rust proof treatment vessel 6 and a chemical polishing vessel 7 in the mentioned order to subject the works to rust proof treatment and chemical polishing. Accordingly, works in barrels the number of which is equal to that of polishing vessels can be subjected to post-polishing treatment, the replacing of the works and pre-polishing treatment simultaneously in different barrels, each of the barrels being subjected to such treatment in succession. Thus, a long-time polishing operation can be carried out at a high efficiency.

Title: Digital data transmitting system
Inventor: TANAKA TOSHIYASU
IPC: H04J3/04
Filed: 1982-03-09
Abstract: PURPOSE:To obtain a digital data transmitting system which can transmit many signals with less number of signal cables and optical fiber links, is easy to extend and is hardly affected by noise, by transmitting digital data of many channels in time division. CONSTITUTION:In the transmission side, an operating section 48 starts a transmission data processing section 4 and transmits data continuously. In this state, the channel information designating a channel to be selected, e.g., No.0 is transmitted from a channel information forming section 47 to channel selectors 40a, 40b. In an example of the execution of this invention, since the data for two- channel's share are transmitted at the same time, No.64 is designated to the channel selector 40b corresponding to No.0. The digital data and channel information selected with the channel selectors 40a, 40b are read in a frame setting section 42 via a gate circuit 41. A frame setting section 42 sets one frame by arranging data for two channels' share to the high-order 2 bits and the channel information for it to the low-order 6 bits.

Title: Calling start circuit
Inventor: YAMANO SEIICHI
IPC: H04M19/08
Filed: 1983-03-07
Abstract: PURPOSE:To reduce the unstable operation of a terminating device of a subscriber's private circuit due to the induced vertical noises by preventing the intermittent cut-off of a DC feeding loop in a feed mode owing to the vertical induction of large amplitude produced to a balanced cable. CONSTITUTION:When a calling start switch 19 is turned off, either one of N and P channel field effect transistors (TRs) 20 and 30 is always off if one of these two TRs is turned on by the AC induced vertical noises. Thus a feed current is never supplied to a DC/DC converter 13. While the capacity value C is selected for capacitors 31a and 31b so that both TR20 and TR30 are not turned off by the AC induced vertical voltage in case the switch 19 is turned on. Thus it is possible to avoid that a DC feeding loop is intermittently cut off by the AC induced vertical voltage.
