IPC: G01N30/60
Filed: 1984-12-28
Abstract: PURPOSE:To improve the production yield of a substrate for a capillary column and to improve the analytic precision of the column by boring a thin groove in both surfaces of a plate material such as glass and vapor-depositing a silicon film on the plate material. CONSTITUTION:A resist film 2 is formed on the plate material such as a glass plate 1. Then, thin grooves 2a are formed by ultraviolet-ray exposure and development. Then, the flank 1a of the glass plate 1 is protected by resist 2b. The substrate is etched to form the thin grooves 2 in both surfaces of the glass plate 1. Then, the resist films 2 and 2b are removed to obtain the glass plate 1 having the thin grooves 3. The silicon film 4 is formed on the glass plate 1 by sputtering to obtain the substrate for the capillary column. Thus, the capillary column substrate is formed by forming the silicon film on the glass plate having the thin grooves, so the yield of the production is improved greatly and the length of the column is increased to improve the analytic precision.

Title: Agc control system
Inventor: TSUDA TAKASHI
IPC: H04B10/079
Filed: 1987-10-30
Abstract: PURPOSE:To reduce the minimum photodetection level by making the level constant when the level detected by a detection circuit is smaller than a prescribed value in the AGC control circuit, fixing the control voltage when the level is larger and varying the multiple factor of the APD so as to make the level constant thereby minimizing the inter-code interference. CONSTITUTION:A bias voltage VAPD control section 33 of the APD controls the multiple factor M of the APD so as to make a difference signal from a comparator 31 zero based on the signal from the comparator 31. A comparator 34 fixes the control voltage generated by a VAGC generating section 32 to a prescribed level when the control voltage VAGC is smaller than the control switching level VB to inhibit the gain control (E-AGC) of the variable gain amplifier. When the VAGC is larger than the VB, the VAGC generating section 32 is brought into the operating state to apply E-AGC to fix the control signal level outputted from the VAPD control section 33. Since the E-AGC by the variable gain amplifier is applied when the photodetection level is small in this way, the bend is not changed near the minimum photodetection level.

Abstract: PROBLEM TO BE SOLVED: To facilitate the formation of a polyolefin having a broad molecular weight distribution by continuously polymerizing an olefin in the presence of a transition metal catalyst while changing the hydrogen concentration in the reaction phase in polymerizers connected in series at least three times. SOLUTION: While the hydrogen concentration in the reaction phase in at least one of a plurality of polymerizers connected in series is being changed at least three times at intervals of below 1/2 of the average residence time of this polymerizer, an olefin (e.g. ethylene) is continuously polymerized in the presence of an olefin polymerization transition catalyst to obtain a polyolefin having a broad molecular weight distribution.
