Title: Radio communication method
Inventor: NAKABAYASHI SUSUMU
IPC: H04W72/04
Filed: 1987-03-31
Abstract: PURPOSE:To always attain stable communication independently of moving position by allowing a base station to detect either transmission level of a mobile station or a relay station at least and regulating a transmitter-receiver so as to switch the frequency to that of either a mobile station or a relay station automatically. CONSTITUTION:When a mobile station is moving at a location disabling the communication with a base station, the base station receives a relay wave from a relay station by an antenna 2 and gives the result to an input/output terminal of a transmitter-receiver 5 via a distributer 1. Then it is possible for the base station and the mobile station to communicate with each other via the relay station. Furthermore, when the mobile station is at the outside of the communication enable area B of the relay station and moves within the communication enable area A of the base station, the base station receives a radio wave from the mobile station by the antenna 2 and gives it to an input terminal of a receiver 3 and an input/output terminal of the transmitter-receiver 4 via the distributer 1. Thus, the base station and the mobile station are communicated with each other directly.

Title: Tool replacing mechanism for machine tool
Inventor: SHIMAJIRI TOKIHARU
IPC: B23Q3/157
Filed: 1979-06-25
Abstract: PURPOSE:To prevent interference between a work and a tool not being used by a method wherein a turret is rotated from a tool holding position of the side portion of a spindle head to a tool replacing position closest to the spindle according to the movement of the spindle head. CONSTITUTION:A spindle head 16 is first driven by a Z-axis driving motor to move upward along a ball spline shaft 24. In this case, a tool turret 26 of a tool replacing mechanism 20 also moves in the direction of Z-axis together with the spindle head 16 because it is also pulled upward by a spring 36 constantly. When a rotary arm 42 contacts the lower end of a stopper member 32a having an adjusted length. The upward movement of the arm 42 and tool turret 26 are blocked. Then, since the continuous movement of the spindle head 16 causes the rotary arm 42 to rotate about a pin 44 as a center, the tool turret 26 rotates from a tool holding position at the side of the pindle shead 16 moving to a tool replacing position closest to the spindle 18.

Title: Production of thin steel sheet having large thickness distribution in width direction
Inventor: IMAI ICHIROU
IPC: B21B1/24
Filed: 1981-05-27
Abstract: PURPOSE:To continuously and stably obtain a thin steel sheet of a semicircular shape in section of which the center in the plate width has a max. thickness and one surface is flat, by incorporating combinations of specific shapes to the upper and lower work rolls of the stands on the front and rear stage sides of hot rolling. CONSTITUTION:In a rolling plant consisting of a roughing mill R2 and hot finishing mills F1-F6, for example, the rolling mills R2 and F1 have upper and lower rolls which both have hollow curves. With the F2-F6 of the latter stage, the upper rolls have less hollow curves and the lower rolls (flat side) have gradually projecting curves. In this case, it is necessary to select an initial curve  for the lower rolls so that they are flattened during rolling by taking the deflection of the rolls owing to rolling load into consideration. In the case of this selection, it is avoided to give a large hollow curve only on one roll for the roughing rolls and the front stage F1 where the large curves are required for a pair of the upper and lower rolls by taking rollability and roll strength in particular into consideration. It is important to change the upper and lower roll distribution ratios of the hollow and projecting (or hollow) curves the nearer the rear stage.

Title: Detection system for dc superposition
Inventor: SHINOZUKA TAKASHI
IPC: H04M3/02
Filed: 1978-06-29
Abstract: PURPOSE: To realize the DC superposition detection system which does not cause any restriction in the inserting position of detection resistor, by monitoring and comparing the average potential to ground across the detection resistor with the output of two low pass filters.  
     CONSTITUTION: When the call out signal is fed from the oscillator IR to called party and if no response from the called party is made, the average potential to ground for the terminals I 1  and I 2  of the detection resistor R 1  is equal to ground potential, and the potentials to ground V 01 , V 02  of the outputs O 1  and O 2  of the low pass filters LPF 1  and LPF 2  show almost the same potential. Next, if this called party responds, since DC signal flows to the detection resistor R 1  by superimposing the call out signal, DC potential is caused between the terminals I 1  and I 2  and to cause the potential difference between V 01  and V 02 . Thus, the change in the potential difference of V 01  and V 02  caused by the presence of the DC superimposing signal is identified at the comparison discrimination circuit COM, allowing to detect the presence of the DC superposition.

Title: Removing method of product of corona discharge deposited on photoreceptor surface
Inventor: NAGAME HIROSHI
IPC: G03G21/00
Filed: 1995-03-10
Abstract: PURPOSE: To efficiently remove the product of corona discharge without producing scratches on a photoreceptor by cleaning the photoreceptor surface in a state at higher temp. by a specified temp. range than the surface temp. of the photoreceptor when an image is formed. CONSTITUTION: An electrophotographic photoreceptor having a diamond-like carbon film (DLC film) as a protective layer on a photoconductive layer is rotated while maintained at higher temp. by 2 to 32 deg.C than the surface temp. of the photoreceptor when an image is formed, to which a cleaning member is brought into contact with for cleaning. To remove the product of corona discharge, it is preferable to maintain the surface temp. of the photoreceptor higher by 2-32 deg.C range than the surface temp. when an image on the DLC film is formed, and moreover, it is preferable to maintain the photoreceptor at 44-52 deg.C while cleaning. The surface temp. of the photoreceptor is maintained at >=44 deg.C because this temp. is the lower limit temp. to mostly remove the product of corona discharge from the photoreceptor surface.  The temp. of 52 deg.C is mostly decided according to the melting temp. of the toner used, and an org. photoreceptor can be heated to about 80 deg.C if this temp. is kept in a short time.
