Title: Transmission system
Inventor: TAKAYAMA HARUYOSHI
IPC: H04L5/04
Filed: 1983-02-22
Abstract: PURPOSE:To improve the transmission efficiency by discriminating a transmission level of a signal consisting of at least a ternary level on a transmission line to halve an address discriminating circuit and to reduce an information frame. CONSTITUTION:A data signal on the transmission line is used at least as a ternary level and the signal is made different in level when the inter-station communication or multiple address communication is executed. In case of the latter communication, since the signal level on the transmission line is different from that at the inter-station communication, it is recognized as the multiple address communication. Thus, a transmission station address S-ADR is omitted in the information frame.

Title: Method for detecting refractive index of opaque oil
Inventor: NISHIMURA HIROYUKI
IPC: G01N21/41
Filed: 1990-02-08
Abstract: PURPOSE:To improve the precision in measuring the refractive index of an opaque oil by mixing the sample oil and a transparent liq. with the refractive index already known in a specified ratio, measuring the refractive index of the liq. mixture and calculating the refractive index of the sample oil from the measured value and the refractive index of the transparent liq. based on a specified expression. CONSTITUTION:A sample oil and a transparent liq. with the refractive index already known are mixed in a specified ratio, and the refractive index of the liq. mixture is measured. The refractive index (x) of the sample oil is calculated from the measured value (m) and the refractive index (a) of the transparent liq. based on the expression x=2m-a. This method can be applied to various petroleum products, the refractive index of which is not precisely measured by the ordinary method due to its low light transmittance, as well as to the almost opaque petroleum products such as heavy oil. Besides, this method is applied to the measurement of the refractive index of a sufficiently transparent sample, and high measurement precision is obtained for a transparent sample.

Abstract: PROBLEM TO BE SOLVED: To perform management to cover the time based on the number of stocks and article-related information until the number of articles in a stock at a new input time runs out even when parts in a pass box outputted to a manufacturing line remain. SOLUTION: A stock managing film is prepared to specify the number of stocks in a storage place, consisting of the number of article containing pass boxes at a point of time when the pass box is present in a storage place and the number of article containing pass boxes at a point of time when the pass box is absent in a storage place, from a discriminate code individually marked on each pass box. The number of article containing pass boxes is set at the number of stocks in a storage place corresponding to the discrimination codes of input pass boxes during input of new articles and the number of stocks in a storage place is set to 0 (step 1). By subtracting the current number of consumed articles from the number of stocks in a storage place for outputting pass boxes, the number of stocks in a storage place for an output pass box is written.  The number of socks in a storage place for an output pass box is set to 0 (step 6). Based on the number of stocks in each stock plate and the number of stocks outside a storage place corresponding to all discrimination codes, the number of stocks is determined.

Title: Method and apparatus fro measuring connection loss of optical fiber
Inventor: FURUKAWA SHINICHI
IPC: G02B6/00
Filed: 1986-02-10
Abstract: PURPOSE:To enable highly accurate measurement of a connection loss from one direction of an optical fiber line, by observing a back scattered light in a mode distribution used in an actual service and a mode distribution composed of a lower- order mode component than this distribution. CONSTITUTION:A laser light source 3 is driven by a pulse signal outputted by a pulse generator 2 synchronizing a timing signal of a signal processing section 1 to generate a pulse light. This pulse light is made incident into an optical fiber 9 to be measured in which optical fibers f1 and f2 are connected at the point J1 through an optical switch 4 and mode controllers 5 or 6, or an optical switch 7 and a optical directivity coupler 8. A part of a scattered light generated in the optical fiber 9 returns to an incident end side, enters photodetector 10 separated from the coupler 8 and amplified 11 to be supplied to a processing section 1. The optical switches 4 and 7 change a signal path over to a controller 5 or 6. The controller 5 is so set that the mode distribution is turned to a normal mode distribution when the pulse light is made incident into the optical fiber 9 while the controller 6 is so set that the mode distribution of the optical fiber 9 will be limited to a low-order mode component only.

Title: Blast processing method
Inventor: TANAKA MASAHARU
IPC: B24C11/00
Filed: 1999-02-04
Abstract: PROBLEM TO BE SOLVED: To prevent degradation of working environments due to dust and to improve processing capability by injecting water together with specified blast media. SOLUTION: When water soluble salt includes first water soluble salt of 60 to 90 wt.% for blast media and second water soluble salt which is 1 to 20 wt.% for blast media and is higher than first soluble salt in dissolving speed to water, it is desirable that dissolving speed of blast media can be increased as compared with a case where water soluble salt includes only first water soluble salt. Blast media is 1 to 10 mm in average grain diameter of a weight reference. When the average grain diameter of blast media is less than 1 mm, blast media is inadequate because blast processing capability is low. In order to obtain an excellent peeling effect and a high scattering effect, 0.01 to 10 kg of water for 1 kg of blast media is supplied to a tip of an injection nozzle, injecting blast media to an object to be processed by using pressurizing gas.
