Inventor: NISHI NORIO
IPC: G02B26/08
Filed: 1981-01-30
Abstract: PURPOSE:To reduce size and losses with simple construction by combining (1Xn) photoswitches consisting of movable fiber bundles with ferromagnetic films thereby forming an (nXn) photoswitch matrix. CONSTITUTION:A movable input fiber row 1 with ferromagnetic films 2, 4 and output fiber rows 3 are disposed within the horizontal and vertical planes in  holding parts 7, 8, and optical fiber bundles 5 with magnetic films for coupling  are disposed at the intermediate thereof. The input fiber 1-i opposes to the i-th  row of the fiber bundles 5, and is made couplable to four pieces of the i-th row  of the bundles 5 by the movement of a movable end 9-i. The fiber 3-j opposes  to the j-th line of the bundle 5 and is made couplable to four pieces of the fibers  of the j-th line of the bundles 5 by the movement of a movable end 10-j. The  coupling of the input and output fibers 1-i and 3-j is obtained by moving input  and output fiber driving parts 11i and 12j. This holds of all the combinations of (i), (j). Thereby, the photoswitch matrix of a small size and low losses with the  simple construction is obtained.

Title: Electrophotographic recorder
Inventor: EBATA NORIO
IPC: G03G15/08
Filed: 1998-01-23
Abstract: PROBLEM TO BE SOLVED: To prevent fogging from occurring even when the residual amount of toner in a developing device is reduced by changing a bias difference between voltage applied on a toner carrier and voltage applied on a supply roller corresponding to the detected residual amount of the toner. SOLUTION: The bias difference is formed between the voltage applied on a developing roller 15 and the voltage applied on the supply roller 14 in order to increase the supply amount of the toner from the roller 14 to the roller 15. For example, by applying the voltage of -300 V on the roller 15 and the voltage of $0450 V on the roller 14, respectively, the bias difference of 150 V is formed. Relating to this device, the bias difference changing means of a CPU 27 controls at least either the voltage applied on the roller 15 or the voltage applied on the roller 14 so that the bias difference may be small at the point when fogging density exceeds a tolerance.

Title: Image forming device
Inventor: SATO SHOGO
IPC: G03G9/087
Filed: 1998-01-23
Abstract: PROBLEM TO BE SOLVED: To provide an image forming device by which an excellent image is stably formed by uniformly and stably electrifying non-magnetic one- component developer (for instance toner). SOLUTION: Positive voltage Vd is applied to a developing roller 27 by a DC power source 51, and the positive voltage Vd is applied to a layer thickness regulating blade 32 by the DC power source 53. Two kinds of the voltage Vb and Vd satisfy the relation of Vd>Vd+Vt (where Vt is the potential difference of the toner T stuck on the developing roller 27 in the direction of a layer thickness). Also, the toner T is a suspended polymerization toner having excellent flowability. Thus, the toner T electrified in a reverse polarity is excellently removed. Also, the action of electric charge injection to the toner T caused by applying the voltage Vd to the layer thickness regulating blade 32 is not generated, and the toner T is sufficiently electrified by triboelectrification caused by the cooperation of the developing roller 27 and a supply roller 28 without having the action.  Thus, the toner T is uniformly and stably electrified.

Filed: 1989-01-20
Abstract: PURPOSE:To enable a higher inspection efficiency with a reduction in erroneous operation by targeting a focus of an ultrasonic probe to a desired depth within an object to be inspected automatically to eliminate complicated manual operation. CONSTITUTION:A target underwater distance is calculated with a target underwater distance calculating circuit 12 from values of an underwater focal range of an ultrasonic probe 1, an internal sound velocity of an object S to be inspected, an underwater sound velocity and a depth (d) desired to be inspected and the results are outputted to an underwater distance comparator circuit 13. The comparator circuit 13 compares the current underwater distance with a target underwater distance and outputs a difference signal proportional to a difference between the both. The difference signal is inputted into a vertical drive signal generation circuit 14 and turned to a drive signal to drive the probe 1 in such a direction as to reduce a value of the difference signal to be sent out to a vertical movement section 2. As a result, the underwater distance comes closer to the target underwater distance gradually and finally, a focus of an ultrasonic beam coincides a desired depth.

Title: Micropressure gauge
Inventor: UTANI KEISUKE
IPC: G01L7/18
Filed: 1979-02-05
Abstract: PURPOSE: To improve measurement accuracy by so composing that the centroids of the horizontal cross sections of vessels X and Y are on the same vertical line and the vessel X connected with a pipe of constant volume can be moved up and down linked with the dial of a micrometer.  
     CONSTITUTION: An inside tank 4 is a movable tank and an outside tank 5 is a fixed tank, and the two tanks 4 and 5 are connected with a pipe whose volume is not changed by the up-and-down motion of the tanks. The inside tank 4 is linked with a micrometer mechanism. If the height from a boundary surface to the level in the inside tank 4 is H 1  and the height to the level in the outside tank 5 is H 2 , and the density values of the liquids are ρ 1  and ρ 2 , equation I holds if the values of pressure exerted on the two liquid surfaces are equal. If differential pressure ΔP is caused between the liquid surfaces under pressure and the moved length of the movable tank 4 is H, equation II holds. Therefore, the differential pressure is expressed from the two equations by ΔP=ρ 1 H. Therefore, if the moved length of the movable tank is measured, differential pressure ΔP can immediately be determined, and the reading of the differential pressure can be magnified by linking the moved length with a micrometer mechanism, the accuracy of measurement can therefore be greatly improved.

Abstract: PURPOSE:To obtain high azimuth resolution by moving a traveling object so that one part of an array composed of parallelly provided photodetectors at equal intervals can be overlapped at the time of reception, and correcting received data by using the information of the overlapped part. CONSTITUTION:At first, the array receives a signal like 2A at certain time and the traveling object receives waves while being turned to a state like 2B by the influence of waves. The reception signals as the outputs from the respec tive receivers at the overlapped part between the two arrays are received with the same sine wave as the transmitted wave as reflected wave at the respective receivers. At the deviated array 2B, the time delay of propagation is generated corresponding to the distance of each receiver. The distance of each receiver is set with the position of the first overlapped receiver as a reference on a lateral axis and the time delay of the receiver on the corresponding array 2A is plotted on a longitudinal axis so as to prepare a linear graph. An equation is calculated from this graph and the time delay of the arbitrary receiver output on the overlapped array 2B to the array 2A is calculated. Then, the already known time delay is corrected to the received signal obtained at each receiver of the overlapped part.
