Title: Printer
Inventor: ODAKAWA KAZUAKI
IPC: B41J19/78
Filed: 1985-06-06
Abstract: PURPOSE:To obtain a printer extremely simple in construction and capable of recording at high speed, by providing a cam rotated by a motor, a lever having one end in contact with the cam and reciprocated with an intermediate part thereof as a fulcrum, and a carriage connected to the other end of the lever. CONSTITUTION:The lever 8 is reciprocated between D and E with a shaft 9 as a center, thereby reciprocating the carriage 11. During this process, a recording head 18 records on a recording paper 27 according to recording commands outputted from a controlling circuit through a flexible printer base 15. Since the lever 8 functions as a lever with the shaft 9 as a center, the motion between A and B is enlarged in a lever ratio CD:AC with the fulcrum C as a center, resulting in a motion between D and E, whereby the carriage 11 is accelerated by a factor of CD/AC. A tooth part of a partial gear 3 is engaged with a paper- feeding gear 20 for each one revolution of a cam disk 4, namely, each one reciprocation of the carriage 1, so that a paper-feeding roller 24 is rotated through a pinion-gear unit 21, 23, and the paper 27 is fed by a one-line amount while being clamped between the roller 24 and a pinch roller 25.

Title: Photographic device suitable for trimming photographing
Inventor: IKEMORI KEIJI
IPC: G02B15/16
Filed: 1987-05-18
Abstract: PURPOSE:To attain a trimming photographing whose picture quality is good by altering the space between lenses at the time of photographing by trimming. CONSTITUTION:In case of executing the trimming photographing, a photographing lens is divided into plural parts in order to obtain a balanced astigmation in a trimming range and by altering the space between lenses of a lens group A and a lens group B, for example, the astigmation in a trimming area can be corrected. In order to prevent the movement of a focus, luminous flux projected from the lens group A is made into afocal light or one near to afocal light. By fixing the lens group B and moving the lens group A which is a nearly afocal optical system to an object side, the correction of astigmation in the trimming range is executed. Then a back focus and a focal distance are not altered so much. Since only one lens group A is moved, mechanical simplification can be attained and photographing having good picture quality can be attained.

Title: Automatic level control circuit
Inventor: NOGUCHI YASUNORI
IPC: H04S7/00
Filed: 1992-05-14
Abstract: PURPOSE:To control the signal level without changing a presence of a stereo signal by managing an ALC level based on a detection voltage signal for a channel with a larger level in input stereo sound signals for the left and right channels. CONSTITUTION:Left and right channel signals Lin, Rin in stereo audio signals are passed respectively through voltage controlled amplifiers 3,4 and detected by detection circuits 5, 6. The detection output is fed to a base of transistors(TRs) 7a, 7b of a voltage selection circuit 7. The selection circuit 7 passes a detection voltage signal with a larger level in two detection voltage signals and the result is fed back to amplifiers 3, 4 as a level control voltage signal. The ALC level is set by a detection voltage and the amplifiers 3, 4 controls the level of the audio input signal based on the level control voltage signal and outputs audio outputs Lout, Rout of left and right channels after the suppression of the level. Thus, the level control in which the presence of the stereo signal is unchanged is attained.

Filed: 1998-04-14
Abstract: PROBLEM TO BE SOLVED: To maintain an always stable adhesion state even on an uneven place and a bending place by enclosing a throating agent comprising clay dry particles swollen and gelled by water absorption and powder in the inside of a prescribed shaped packing cylindrically woven by the weaving thread of biodegradable poly lactic acid fiber capable of dissolving by strong alkali water in a substantially full state. SOLUTION: After being cylindrically woven into the diameter D of about 10-17 mm by the weaving thread of biodegradable poly lactic acid fiber dissolved by strong alkali moisture of pH 11 or more, the inside of a packing cut into the length L of about 2-5 m is substantially filled with a throating agent comprising bentonite swollen and gelled by water absorption, sepiolite, the other clay dry particles or powder. Since the packing 11 is freely extended by adapting the swelling and gelling of the throating agent, it can be bent and deformed even when the throating agent is enclosed in a substantially full state. As the result, it reasonably follows up a part in which the unevenness of laitance is strong and a bent surface of H shape steel embedded in concrete, and can be set and used in an always stable adhesion state.

Abstract: PURPOSE:To constantly obtain a stable impacting force and facilitate arbitrarily selecting an impacting force, by a method wherein a rotating force of a driving lever is accumulated in a driving spring, and the force thus accumulated is released as an impacting force. CONSTITUTION:When the driving lever 1 is rotated in the direction of an arrow A, an energy-accumulating bar 13 is moved in the direction of an arrow C, while a driving bar 3A is restrained from moving by a locking lever 14. Meanwhile, a driving force is accumulated into the driving spring 12 by the movement of the bar 13. When the bar 13 is moved further in the direction of the arrow C, a releasing pin 16 comes into contact with the lower end of the locking lever 14 to rotate the latter counterclockwise. Then, the engagement of the lever 14 and a hook part 3Aa is released, and the driving bar 3A is released from he hold by the lever 14. Accordingly, the bar 3A is rapidly moved in the direction of the arrow C while simultaneously rotating a driving wheel 4 in the direction of an arrow B, resulting in an impacting action.
