Title: Recording paper reciprocal feeder
Inventor: YASUOKA SADA
IPC: B41J15/00
Filed: 1987-03-02
Abstract: PURPOSE:To prevent any slack in paper at the time of c.w. or c.c.w. rotation from occurring, by setting a driving gear of a drive shaft 35a for a paper feeding drive roller at the upstream side down to two stages of both large and small diameters, and engaging them each with reciprocal feed gears via a one-way clutch at time of the c.w. or c.c.w. rotation. CONSTITUTION:In a driving gear 95 transmitting driving force to a drive shaft 35a of a paper feeding drive roller at the upstream side, there are provided with a large diametral gear 95a and a small diametral gear 95b concentrically in two stages. A backward feeding gear 96a to be engaged with the large diametral gear part 95a via a one-way clutch 100 is pivotally attached to this drive shaft 35a, and a forward feeding gear 96b to be engaged with the small diametral gear part 95b is as well fitted with some play. In addition, a seat 10a is connected to the shaft 35a, and a clutch spring is engaged with the rotor pivotally attached to a rotary bearing part via a one-way clutch 104 at a shank of the gear 96b and an outer circumferential surface of the seat 101. Therefore, rotation at time of c.w. or c.c.w. turning to the drive shaft 35a is varied to some extent, whereby any paper feeding speed at the time of both reciprocal operations can be made later than speed at the downstream side, thus slack in paper at a printing part is preventable from occurring.

Title: Frequency stabilized laser light source
Inventor: AKIYAMA KOJI
IPC: H01S5/068
Filed: 1990-02-28
Abstract: PURPOSE:To obtain a non-modulation high frequency stabilization optical output by controlling oscillation frequency of a first semiconductor laser to an absorption line frequency through current modulation, and further controlling oscillation frequency of a second semiconductor laser. CONSTITUTION:Output light of a semiconductor laser 1 controlled to an absorption line of a standard substance is emitted via a beam splitter 2 and combined through a polarized beam splitter 12 with output light of a semiconductor laser 10 emanating through a beam splitter 11. The combined light is matched in polarization plane at a polarized beam splitter 13 and thereafter a beat signal therebetween is detected by a photodetector 14. After the heat signal is mixed with an output of an oscillator 15, a mixed signal is subjected to synchronous detection in a synchronous detection circuit 17 taking an output from an oscillator 8 as a reference signal. A PI control circuit 18 controls oscillation frequency of a semiconductor laser 10 such that a synchronous detection output is 0. Thus, the oscillation frequency of the semiconductor laser 10 is shifted by the oscillation frequency of the oscillator 15 from the center frequency of the semiconductor laser 1 and is partly outputted via the beam splitter 11.

Filed: 1988-03-02
Abstract: PURPOSE:To construct a capacitor sufficiently high in breakdown strength, low in leak current, and adequate in charge-storing capability by a method wherein an electron-conductive oxide film is provided in contact with a dielectric film. CONSTITUTION:An electron-conductive oxide film made of oxide with its formation enthalpy higher than that of oxide forming dielectric is provided in contact with at least one side of the dielectric film. For example, on a silicon substrate whereon a storage capacitor is to be formed, a tantalum thin film is formed by a high-frequency spattering method using a tantalum-made target. An oxidizing gas is introduced into a diffusion furnace, and the entire tantalum thin film is converted into an oxide film after exposure to the oxidizing atmosphere for 20minutes at 600 deg.C. Next, a molybdenum oxide film is attached to the tantalum oxide film and then a molybdenum metal is further deposited for the construction of a capacitor. The result is a storage capacitor high in breakdown strength, low in leak current, and enhanced in charge-storing capability.

Filed: 1990-02-27
Abstract: PURPOSE:To suppress noise to attain stable reading and to prevent data holding capacity from being deteriorated by setting up a rewriting time in accordance with the rewriting frequency of a memory cell part. CONSTITUTION:A reading circuit 6 reads out the current rewriting frequency of a storage part and a programming circuit 8 selects an address in which rewriting time data corresponding to rewriting frequency stored in a storage part 5 are written and inputs the binarized rewriting time data to one inputs of plural 2-input EXNOR gates G2 to G5 in a setting circuit 7 through the circuit 6. Respective outputs from a clock frequency dividing circuit 10 are inputted to the other inputs of the gates G2 to G5, and when respective inputs coincide with each other, the outputs of the gates G2 to G5 are turned to 'H', and inputted to a multi-input ANG gate G1. The output of the gate G1 turns to 'H', when the levels of respective rigids are matched with each other, and the erasing cycle is completed. Similar operation is repeated again to write data within the same time, '1' is added to the rewriting frequency of the storage part 4 to update the rewriting frequency.

Title: Partial discharge detector
Inventor: SENBA KATSUAKI
IPC: G01N29/14
Filed: 1990-02-28
Abstract: PURPOSE:To prevent influence of noise due to the external environment in the detection of a corona discharge by inserting an ultrasonic wave detector in a vessel through a sealing material which does not propagate an ultrasonic wave. CONSTITUTION:An O-ring 5 of a sealing material which does not propagate an ultrasonic wave is disposed in a hole 2a in a conduit (vessel) 2, and an ultrasonic wave conducting rod 4a of an ultrasonic wave detector is inserted into the conduit 2. If a corona discharge is generated between a power bus 7 and the conduit 2, an ultrasonic signal generated, for example, in SF6 insulation gas is propagated by the rod 4a inserted into the conduit 2 to be detected. The signal traveling through the wall of the conduit 2 is not detected by the rod 4a due to the shut-off by the ring 5. Thus, only the ultrasonic wave generated by the corona (partial) discharge can be accurately detected by a detector 3, and influence of noise due to the ultrasonic wave due to wind, rain, etc., to be propagated by the wall of the tube 2 can be prevented.

Abstract: PURPOSE:To make it possible to eliminate the necessity of cumbersome work by providing a disc secured to a core member onto which a tape is wound, a rotation limiting member which may abut against the disc, a spring means for allowing the rotation limiting member to abut against the disc and a release means for separating the rotation limiting member from the disc when a cassette is loaded. CONSTITUTION:When a ribbon cassette is loaded on a carriage 11, a cassette casing 21 is secured by a pawl 13 while a releasing projection 19a is inserted into an insertion hole 39. Then, the projection 19a abuts against a stopper 37 to separate the latter from discs 27, 29 overcoming the resilient forces of leaf springs 33, 35, and therefore, the rotational limitation to a wind-up ribbon shaft 23 and a feed ribbon shaft is released to allow an ink ribbon 31 to move. Further, when the cassette is removed from the carriage 11, the casing 21 is released from the pawl 13 while the projection 19a is pulled off from the insertion hole 39. Further, the stopper 37 is made to abut against the peripheral edges of the discs 27, 29 by the resilient forces of the leaf springs 33, 35, and is secured. Accordingly, the rotation of the ribbon shafts 23, 25 is limited, thereby it is possible to prevent the movement of the ribbon 31.
