Title: Paper feeder for sheet printer
Inventor: NISHI HIDEKAZU
IPC: B65H3/08
Filed: 1994-05-18
Abstract: PURPOSE:To prevent the defective paper feeding by restraining flapping of paper sheets caused by influence of air. CONSTITUTION:Air is blown out of a blower 2 to the upper tip of loaded paper sheets 10, and a floating area H1 of the uppermost paper sheet 10a floats. A high control bar is a bar to detect a loading height of the paper sheets 10, and pressurizes the paper sheets 10 in the arrow 90 direction. The floated paper sheet 10a is sucked by a sucker 4, and is sent out to a printing process. A guide bar 12 is installed on the high control bar, and a contact part 12K is in contact with a part of the floating area H1. The contact part 12K is higher than an unfloating height L1 of the uppermost paper sheet 10a, and is situated in a restraining height L3 lower than the maximum height L2 of the floating area H1. Thereby, the uppermost paper sheet 10a can be fed in a proper condition.

Title: Bit weight order display/connection validity check system
Inventor: SHIZAKI TAMAKI
IPC: G06F17/50
Filed: 1997-04-07
Abstract: PROBLEM TO BE SOLVED: To display the previously registered bit weight order of symbols at the time of arranging symbols in a circuit drawing input system, and to check whether or not a connection relation is valid in terms of the weight of bits after the connection of an input pin with an output pin. SOLUTION: When symbols are arranged at designated positions according to a symbol arranging instruction, a bit weight order displaying means 4 checks which of an ascending order or a descending order the bit weight order of arranged symbols is applied as from previously registered information, and displays the bit weight order. A bit weight checking means 5 traces the destination of connection of a pin by a connection destination tracing part 6, checks the bit weight order of the symbols to which each connected pin is belonging and how many bits there are before the pin, and judges whether or not connection between pins is valid in terms of the weight of bits. Then, an error mark displaying part 8 displays an error mark when the connection between the pins is not valid in terms of the weight of bits.

Title: Multi-track thin-film magnetic head
Inventor: OODOI YUUZOU
IPC: G11B5/31
Filed: 1984-05-23
Abstract: PURPOSE:To improve the efficiency of information recording, reproducing, and erasing operations, by forming the optimum gap length to a thin-film magnetic head in accordance with recording wavelength zones used for respective tracks. CONSTITUTION:A groove 5 is provided in a substrate 1 and the 1st core 2 is formed in the groove 5 so as to give a level difference to the 1st core 2. After forming gap members 3a and 3 on the 1st core 2, the 2nd core 4 is formed in such a way that the 2nd core 4 faces the 1st core 2. The depth of the groove 5 formed in the substrate 1 is made equal to the difference G2-G1 in gap lengths and the gap member 3 is worked so that the thickness of the member 3 can become equal to the gap length G1. Since the plane formed by each 2nd core 4 becomes almost a flat plane in such a way, the efficiency of the information recording, reproducing, and erasing operations can be improved and, at the same time, a multi-track thin-film magnetic head having high machining accuracy can be obtained.

Inventor: WATANABE NOBUO
IPC: G01B11/22
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To accurately judge the propriety of the fitting condition of a cap. SOLUTION: The image of a cap 3, photographed by a CCD camera 22, is converted into a digital signal by an A/D converter 12A, and then is made into binaries of white and black by a binary circuit 12B. Next, a histogram is prepared by a histogram preparing circuit 12C by image data made into the binaries. The side surface of a cap 3, except the place of the upper end part of the cap 3 in the histogram, is set as a judgment objective range by an offset circuit 12D and a range setting circuit 12E, thereby being transmitted to a judging circuit 12F. Thereupon, the depth of the screw part of the cap 3 is operated based on the value of histogram within a judgment objective range by the circuit 12F, and the operated depth of screw part an the depth of the screw part adopted as the reference stored previously are compared.  The fitting failure of the cap 3 can be judged by the circuit 12F when the operated depth of screw part is shallower than the depth of the screw part adopted as the reference.

Abstract: PURPOSE:To control characteristics such as a hysteresis electric-current width, an oscillation threshold value and the differential quantum efficiency during a bistable operation by a method wherein a terminal to impress an electric current on a saturable absorption layer is installed, the electric current is impressed on the saturable absorption layer and a carrier density of the saturable absorption layer is controlled. CONSTITUTION:If a second electrode terminal 12 is biased as a positive side and a first electrode terminal 11 and a third electrode terminal 13 are biased as a negative side, this assembly functions as a bistable semiconductor laser which has two stable levels with reference to an input of an electric current. The electric current which is impressed on a second clad layer 9 from the electrode terminal 12 via a p-type impurity diffusion region 16 and a p-type electric-current impression layer 5 is divided into two parts for an active layer 8 and a saturable absorption layer 6 in accordance with a bias value at the electrode terminal 11 and the electrode terminal 13 and is then impressed on the two layers. The saturable absorption layer 6 functions as a loss of finite magnitude when a photon density or a carrier density is sufficiently small, and has a character that the loss non-linearly approached zero when the photon density or the carrier density becomes big to a certain extent. If a negative bias value to be impressed on the electrode terminal 13 is adjusted optimally, the carrier density of the saturable absorption layer 6 can be changed and the magnitude of the absorption loss can be controlled.

Abstract: PURPOSE:To form a back-to-back diode and to protect gate insulation film by forming a p-type floating base deeper than the P<-> type floating base and by allowing N<+> cathode layer to be subject to diffusion formation. CONSTITUTION:Inverse breakdown voltage of a gate protection diode D2 or D2 is determined by the concentration and slope of impurities at a P-N junction J4 of a wide flat area within a bulk formed by first and second cathode areas 14 and 16 and second and third floating base areas 18 and 19. The gate protection diode shown by D2 and D3 in the equivalent circuit of this semiconductor device is formed in back-to-back. When a voltage which is greater than insulation breakdown voltage is applied between the G and S, the D2 and D3 are activated so that no breakdown voltage is produced between the G and S, thus effectively preventing insulation breakdown of the film 7 from being generated.
