Title: Roll film conveying device
Inventor: SAITO TAKANORI
IPC: G03B23/02
Filed: 1986-01-30
Abstract: PURPOSE:To spread flanges nearby a film take-up part and to prevent a film from being wound defectively by supplying slantingly the front end of the film to a take-up reel. CONSTITUTION:A guide member 17 guides the front ends of roll films F1 and F2 supplied automatically to the take-up reel 3 to the film take-up part of the take-up reel 3, and the tip of this member 17 on the side of a take-up reel flange 3a is so shaped that the front ends of the films are supplied slantingly to the take-up reel 3. The films reaching the gap between flanges in the slanting state increases the gap between the flanges 3a nearby the film take-up part. The films reaching a take-up shaft 3b are wound by being hooked by take-up claws. The flanges 3a of the take-up reel 3 are spread nearby the take-up shaft 3b, so a smaller conveyance force is required than when the outer peripheral parts of the flanges are spread, and the films are taken up securely.

Title: Hybrid ceramic stator blade
Inventor: ASAKUMA KENSUKE
IPC: F01D9/02
Filed: 1991-02-12
Abstract: PURPOSE:To prevent a metal temperature of a core bar from increasing by improving sealability between a ceramic blade-like sleeve and metal outer/inner shrouds. CONSTITUTION:A cylindrical blade-like sleeve 3 which is fitted to an outer peripheral part of a core 2 is held between an outer shroud 1 and 1 and an inner shroud 4. A thermal insulation member 8 and a pressing plate 9 are sandwiched respectively between the outer shrouds 1 and the blade like sleeve 3, between the inner shroud 4 and the sleeve 3. The pressing plate 9 on the outer shroud 1 is constantly pressurized against the side of the blade-like sleeve 3 by means of a coil spring 13 through a spring pin 12. A satisfactory sealing condition is thus obtained between the core 2 and the blade-like sleeve 3 even in case that thermal-expansion difference presents therebetween. The metal of the core 2 can be prevented from rising in temperature by high-temperature gas-inflowing.

Title: Circuit arrangement which controls series logic circuit of clock control source
Inventor: HANSU BOODO RAAE
IPC: H02M3/156
Filed: 1987-01-30
Abstract: A circuit arrangement for the control of the series switching element of a clocked power supply unit has a pulse signal (Vt) delivered by a pulse generator. The pulse-interval ratio of the pulse signal can be varied as a function of a regulating signal (Vc) derived from the output side of the power supply unit and delivered by way of an optoisolator (13). The portion of the circuit employed as pulse generator (1) includes an operational amplifier (10) with feedback at both inputs. One feedback branch of the amplifier (10) contains at the amplifier input a capacitance (15) and a variable resistance. The variable resistance is formed by the parallel connection of a phototransistor (132) of an optoisolator (13) and an ohmic resistor (12). Accordingly, it becomes possible to produce a variation of the pulse-interval ratio of the pulse signal (Vt) either solely by modification of the pulse length or solely by modification of the pulse intervals. One input of the operational amplifier (10) may be connected with a start-stop switching stage (3), which also uses an op-amp ( 20). The two operational amplifiers (10, 20), which both are employed as open collector voltage comparators, can also be made as part of an integrated unit.
