Title: Controller for copying machine
Inventor: IWAMOTO MINORU
IPC: G03G21/00
Filed: 1989-11-01
Abstract: PURPOSE:To prevent the occurrence of miscopying by using a controller resetting a copying mode to a standard mode after copying is finished and a prescribed time passes and controlling the controller so as to shorten a prescribed time when an automatic document feeder (ADF) is used compared with the time when it is not used. CONSTITUTION:In the controller of the copying machine resetting the copying mode to the standard mode after one document is copied, a control means resets the copying mode to the standard mode after copying is finished and a prescribed time, for instance, about one minute passes, when the ADF is not used. When the ADF is used, the control means switches an reset action to obtain the standard mode just after one copying action is completed. Thus, the occurrence of miscopying can be prevented.

Abstract: PURPOSE:To perform reliable exposure throughout a whole range by a method wherein, when, during completion of detection of size, the forward end of a hand insertion document is moved in short of a given position situated this side of an exposure part, the document is fed as it is, and when it already passes the given position, it is moved backward to the given position once. CONSTITUTION:When a document is inserted from a position above a table 95 into a gap between hand insertion rollers 94 by hands, a sensor S14 located right before the document is turned ON to rotate the rollers 94 and is conveyed to a hand insertion passage 92 through a switching claw 96. Length is detected from a time in which the document passed the sensor S14, length is detected and width is detected by a sensor S13 right after the document, namely, size is detected, and from the data, a sheet size is detected. In the case of a small document (<B5) in which at a point of time when size is detected, the forward end of the document is conveyed in short of a sensor S18 located right before a timing roller 81, loop processing is applied thereon as it is to convey it to an exposure part D. Meanwhile, when the document is conveyed in short of the sensor S18, a conveyance system is reversed to move backward the document from a document discharge passage 98 to a discharge tray 97 once. When the document is moved aside from the sensor S18, it is conveyed to the timing roller 81 again.

Title: Vibration resistant floor
Inventor: KAJIWARA KOICHI
IPC: E04F15/18
Filed: 1999-10-05
Abstract: PROBLEM TO BE SOLVED: To provide a vibration resistant floor capable of damping vibration by means of a simple structure and being easy to transfer. SOLUTION: In a clean room 24 separated into an underfloor space 28 and an indoor space 30, a vibration resistant floor 10 is installed in an area where a vibration resisting device 38 is installed. The vibration resistant floor 10 is of a sandwich structure having mortar 20 sandwiched between a bottom plate 12 and a top face 14. When the vibration resisting device 38 is mounted on the vibration resistant floor 10, transfer of external vibration to the vibration resisting device 38 can be prevented by means of the mass of the vibration resistant floor 10 and the damping characteristic of the mortar 20 which increases the mass. Since the vibration resistant floor 10 is bolted to a girder 22, it can be easily transferred.

Title: Frequency converting circuit
Inventor: BABA SATOSHI
IPC: H04B1/26
Filed: 1989-10-31
Abstract: PURPOSE:To independently operate a device even at the time of abnormality of another device by detecting it by a detector that the local oscillation signal from another device is not inputted to the device and controlling a switch to connect a frequency converter to a local oscillator provided in the device. CONSTITUTION:If the local oscillation signal from another device is not inputted to a synchronous input terminal 1 because the power source of another device is turned off or a connection cable is slipped out or disconnected, the reduction of the input level is detected by a detector 5 and a controller connects a common terminal C of a switch 7 to a switching terminal B by switching. Consequently, the output of a local oscillator 4 provided in the device is amplified by an amplifier 2 and is inputted to a frequency converter 3, and a frequency conversion signal is outputted. Thus, the device is operated independently of another device even though the local oscillation signal from another device is not inputted.

Filed: 1990-10-24
Abstract: PURPOSE:To manufacture a reliable multilayered printed board at a high productivity without producing pollution by treating the copper foil surface of an inner-layer plate formed with a printed wiring network in an atmosphere containing a reducing gas and platinum catalyst after the copper foil surface is chemically oxidized. CONSTITUTION:An inner-layer plate which is formed in such a way that the plate is treated in an atmosphere containing a reducing gas and platinum catalyst after a brown or black copper oxide surface is formed by chemically oxidizing the copper foil surface of the inner-layer plate formed with a printed wiring network, is used as an intermediate layer. When a multilayered printed board is manufactured by this manufacturing method, the occurrence of 'hallow' which tends to cause such faults as electric short circuit, etc., due to the brown or black copper oxide melted in the plating liquid in the through hole plating process for electrically conducting printed wirings to each other is sharply reduced or completely eliminated. Therefore, a highly reliable multilayer printed wiring board can be manufactured at a high productivity without producing pollution.

Title: Method for adjusting coefficient of coupling in optical fiber directional coupler

IPC: G02B6/28
Filed: 1985-12-18
Abstract: PURPOSE:To relieve an eccentric core fiber having a parameter deviated from a design value by rotating the fiber after production to set intervals of cores. CONSTITUTION:Eccentric core fibers 1 and 2 are produced after a core diameter 2a, a specific refractive index difference DELTA, and a distance S from the outside peripheral surface of the fiber to the center of the core are so determined that a desired coupling coefficient K is obtained. Two eccentric core fibers 1 and 2 have outside peripheral surfaces brought into contact with each other, and one or both of them are rotated in this state to set the interval between cores 1A and 1B to a desired value (d). A preliminarily designed value is selected as this value (d) if the diameter 2a and the specific refractive index difference DELTAof cores 1A and 1B are as designed after production. If they are deviated from design values after production, the core diameter 2a and the specific refractive index difference DELTA after production are used to calculate again the interval between cores by which the desired coupling coefficient is obtained, and the value (d) is corrected to the calculated value.

Abstract: PURPOSE:To easily obtain an excellently reproduced signal with small quantity of reflected wave noise by providing a noise level detecting means which detects a noise level in a reproduced signal, and an optical path regulating means which regulates the optical path length of laser beams according to the obtained noise level. CONSTITUTION:A signal to detect the reflected wave noise level drives an optical disk 7 through a noise detecting part 21, a motor control part 22, a motor driving part 23, and a slider motor 24 in the width direction. Further the optical distance between an LD (semiconductor laser) 1 and the signal surface of the optical disk 7 is regulated so that the reflected wave noise of the reproduced signal may be at <= a regulated value. Thus even when the optical length between the LD 1 and the signal surface of the optical disk 7 is changed due to the slight width change in units of a wavelength of each optical disk, the excellently reproduced signal with small quantity of reflected noise can be obtained.
