Title: Gear, sheet feeder, and image reader
Inventor: YAMAUCHI TSUYOSHI
IPC: B65H3/06
Filed: 1995-09-29
Abstract: PROBLEM TO BE SOLVED: To reduce the size of a sheet feeder and an image reader by integrally providing an engagement arm on which a claw part locked in a groove provided in a gear shaft is formed on the tip thereof, and using a gear simply fitted to the gear shaft. SOLUTION: The inside diameter of a gear fitted to the end part of a feed roller shaft, which is engaged with a shaft as a whirl-stop in the rotating direction of the shaft, is D-shaped. The gear is provided with an engagement arm 307 having a claw part 306 as a stop in the thrust direction at the tip thereof. The length (u) and thickness (t) of the claw part 306 of the engagement arm 307 of the gear are set to be engaged with a groove to which an E-ring can be fitted. A gear shaft to which a D-cut gear is fitted is provided with a groove 308 where the claw part 306 can be engaged. Thus, when the gear is inserted in the shaft, the claw part 306 is engaged with the groove 308 by the elasticity of the engagement arm 307 to keep the gear from slipping off. Accordingly, the gear can be simply fitted only by inserting the gear in the shaft.

IPC: C23G1/08
Filed: 1990-09-21
Abstract: PURPOSE:To easily, surely and inexpensively produce the heat treated steel pipe having excellent quality in surface roughness by subjecting the steel pipe to a 1st heat treatment in a direct firing furnace, pickling this pipe to remove its surface scale and subjecting the steel to straightening then to a heat treatment for scale formation. CONSTITUTION:The 1st heat treatment of the steel pipe is executed in the direct firing furnace which burns fuel, such as petroleum and gas, and directly heats the steel pipe at the temp. exceeding about 700 deg.C. This steel pipe is pickled in order to remove the surface scale generated on the surface of the steel pipe by this 1st heat treatment. The steel pipe is then subjected to the straightening in order to set the state (straightness, out of roundness, etc.) of the steel pipe. The execution of the straightening by using ordinary straightening rolls is possible. The steel pipe is thereafter heat treated at about 500 to 700 deg.C temp. range to form extremely thin scale layers of about 1 to 10mum on its surfaces. The heat treated steel pipe having the good surface roughness and corrosion resistance is easily, surely and inexpensively produced in this way without using an oxygen-free atmosphere furnace.

Title: Digital clock generation device
Inventor: HIRAMATSU YONEJIRO
IPC: H03B28/00
Filed: 1995-09-29
Abstract: PROBLEM TO BE SOLVED: To heighten the frequency range and to reduce spurious waves. SOLUTION: The digitizing signal sin (2π fct) sent from a reference signal generator 50 undergoes phase modulation via a phase modulator 30 based on Δf that is set at a terminal 21 of an integrator 20. This modulation output is outputted to the terminals 44 and 43 as the clock signals of frequency fc ±▵f. That is, cos (C) and sin (C) which are produced by C corresponding to the set ▵f are digitally multiplied by sin (2π fct) and -cos (2π fct) from a reference signal by the multipliers 35 and 36 and then added together at an OR gate 39'. Thus a modulated signal cos (2π fct+C) is obtained and outputted. The spurious waves caused by a cos ROM 32 can be reduced when a complement of +1 sent from an IDR 46 undergoes the phase updating of the ROM 32 as a 2CK via a correction circuit 45 against a reference cycle CK.

Filed: 1995-09-29
Abstract: PROBLEM TO BE SOLVED: To provide an adaptive control method for periodic signal to properly cope with change, etc., of the external conditions of an controlled object with high convergent stability. SOLUTION: A frequency detection part 10 detects the object frequency component ω of a controlled object signal and outputs it as a signal (x) of frequency ω/2 before frequency compensation. A frequency compensation part 11 adds frequency q/2 to the frequency ω/2 to output a signal (x'). An adaptive filter W13 consists of two variables of an amplitude compensation term (a) and a phase compensation term ϕ. The signal (x') is compensated in its amplitude and phase by the filter W13 and outputted as a signal (y). The signal (y) is squared at a frequency multiplication part 13, and the gain Aω and the transmission function Gω of phase delay Φω are applied to the signal (y) in a transmission system 14. Thus, the signal (y) is outputted as a signal (z).  The external force (f) is added to the signal (z) at a point of application 15a, and the difference between the signal (z) and a target (d=0) is returned to the filter W13 as an error signal at a point of application 15b, and the filter W13 is successively updated by the gradient method.
