Title: Copy paper delivery and reversal device
Inventor: HAMANAKA IZUMI
IPC: B65H29/58
Filed: 1984-12-14
Abstract: PURPOSE:To speed up reversing and delivering a copy paper by enabling the paper to be fed on a paper reversal and delivery path in a reverse direction by reversing the rotation of a reversible roller provided in a double side copying process following a paper introducing path. CONSTITUTION:A copy paper R is fed through an upstream roller 11, a paper delivery path (a), and a downstream roller 12 and is directly delivered outside as shown by a two-dot chain line in the accompanying drawing. On the other hand, a copy paper already fixed proceeds to a paper introducing path (b) through the upstream side edge 13a of a movable separator 13 and, while descending, passes the lower edge 13b of the separator 13, proceeding to a double-sided copy path 5. Then the advance of the paper is reversed by the reversal of a reversible roller 18 provided in the path 5 and fed to a paper reversal and delivery path (c). The paper is never fed back to the paper introducing path (b). When the tail end of the paper fed into the double- sided copy path 5 through the paper introducing path (b) passes a sensor 19, the advance of the paper is reversed and the paper is fed into the paper reversal and delivery path (c) with the leading end changed from the previous tail end. When the tail end of this paper passes another sensor 20, the advance of the paper is reversed again and the occurrence of a jam is prevented by increasing the reversing speed.

Title: Optical electric field sensor
Inventor: TOGANO YUICHI
IPC: G01R29/08
Filed: 1996-10-04
Abstract: PROBLEM TO BE SOLVED: To provide a sensor less influenced by noise by changing intensity of an optical signal from a light source on the basis of voltage of a receiving signal impressed on the modulation electrode of a branch interference type optical wave guide and emitting it to an optical detector as modulation light. SOLUTION: A two-branched interference type optical wave guide 32 is formed on a substrate 31 having electro-optical effect of a sensor head 1, and a modulation electrode 35 is provided adjacent thereto. An electric field generated in the wave guide 32 leads to local refraction index change by a signal input from a receiving antenna 10 to the electrode 35, the light beam branched into two from an optical fiber 7, the light beam directed to an optical fiber 8 generates interference caused by a phase difference at the time of confluence. In other words, an input electrical signal of the antenna 10 to the head 1 is converted into an optical signal which is intensity-modulated. The conversion light is detected with an optical detector 3. Thereby a sensor of less influence of noise and less transmission loss can be obtained.

Filed: 1996-10-04
Abstract: PROBLEM TO BE SOLVED: To provide a method of photooxidation of a collagen fiber connective tissue in spite of the fact that light transitivity in an untreated cartilaginous tissue is low. SOLUTION: In a photooxidation treatment method of a collagen tissue, before irradiation of the light, the tissue 1 is pretreated by an adjusting aqueous solution 5.

Filed: 1986-11-06
Abstract: PURPOSE:To contrive high efficiency and long life by continuously growing epitaxially by using chlorine as the dopant of n-type ZnSe and nitrogen as the dopant of p-type ZnSe. CONSTITUTION:The reason why GaAs is used for a substrate 1 is that the lattice constant is nearly the same as that of ZnSe and that the excellent single crystal layer of the ZnSe can be grown epitaxially. An appropriate impurity is evaporated with a crystalline matrix material ZnSe and a chlorine-doped N-type ZnSe layer 2 and a nitrogen-doped P-type ZnSe layer 3 are continuously grown in sequence by changing the sort of the impurity. The electron density of the chlorine-doped N-type ZnSe layer 2 is made 5X10<16>cm<-3> or more to obtain high efficiency. If excessive chlorine is doped, a deep level is formed in band energy and the light emission except blue is made stronger so it is required to restrain the addition of the chlorine to an extent of electron density 5X10<18>cm<-3> or less. The thickness of the chlorine-doped N-type ZnSe layer 2 is made 1mum or more.

Abstract: PURPOSE:To accurately detect the presence of short-circuit of a junction as digital information by detecting the presence of the short-circuit of junction from an output voltage of a semiconductor element. CONSTITUTION:Since a constant current IC is supplied to Zener diodes ZD0, ZD1, ZD2 normally from MOS transistors (TRs) CC0, CC1 and CC2, a Zener voltage VH is generated from the output of the Zener diodes ZD0, ZD1 and ZD2 and an output level of inverters I0, I1, I2 goes all to '0'. In applying current/voltage pulse between a trim pad PAD1 and a COM, the Zener diode ZD1 causes breakdown and the injection of the Zener diode ZD1 is short- circuited. Thus, the Zener diode ZD1 acts like an element equivalent to a resistive element with a low resistance and an output voltage of the Zener diode ZD1 is a low voltage VL. Thus, the output voltage of each semiconductor element is accurately detected depending on the presence of the short-circuit of the junction by giving a prescribed current to the semiconductor element group having the Zener characteristic.
