Title: Electronic apparatus
Inventor: OSATO KENICHI
IPC: G07B1/08
Filed: 1993-06-30
Abstract: PURPOSE:To make it possible to prevent penetration of dust into a printing part from a paper feed port or a paper discharge port and to prevent thereby occurrence of a printing fault and degradation of the quality of print. CONSTITUTION:An electronic apparatus is constructed of a body case 10 and an upper case 11 provided elevatably on the upper side of the body case 10. An input part 12 and a display part 13 are provided on the upper side of the upper case 11 and a paper feed port is opened in the front end face on the rising side of the upper case 11, while a paper discharge port 20 is opened in the rear end face thereof. Besides, a projecting part 15 closing up the paper feed port in a state wherein the upper case 11 is made to fall down on the body case 10 and held thereon is so provided as to project on the upper side of the body case 10. According to this constitution, the upper case 11 is made to fall down on the body case 10 when the apparatus is not used. Since the paper feed port is closed up by the projecting part 15, dust is prevented from penetrating into it and thus a printing fault is eliminated.

Title: Semiconductor sense amplifier
Inventor: YAMADA TATSUO
IPC: H03K5/02
Filed: 1979-12-13
Abstract: PURPOSE:To make it possible to sense and amplify even a voltage differing much from a normal threshold voltage, by clamping an input voltage. CONSTITUTION:To sense an input voltage while the threshold voltage of input FET24 is set to 0.7V and the input voltage is 4V, the ratio of the value of the 1st resistance 16 to that of the 2nd resistance 18 should be 3.3:0.7 when the 2nd potential source terminal 15 is grounded. A change in potential at connection point 17 can be made larger by holding the 2nd potential source terminal 15 at a negative potential. When the value ratio of resistance 16 to resistance 18 is changed to 3.2: 3.3, an input voltage of 3.5V develops an input voltage of 0.29V to cnnection point 17 and that of 4.5V develops 1.05 to point 17, so that an enough potential change to drive FET24 can be obtained. In addition, this IC-implementation is facilitated by using MOSFET for voltage division.

Abstract: PURPOSE:To enable simultaneous and highly precise measurement of a position (optical axis) of a light beam and the radius thereof by a method wherein the light beam from a light-emitting body is split in two by a light-splitting means and the split beams are sensed by a line sensor and an analog sensor respectively. CONSTITUTION:A light beam generated from a semiconductor laser 3 is reflected from a reflector 4 and also scanned in the horizontal direction. Part of this light beam passes through a half mirror 5, while the other is reflected from the mirror 5. The passing light beam is sensed by a semiconductor position detecting element of a line sensor 6 and the position thereof, i.e. the optical axis, is measured thereby and displayed in a display element 10a of a control box 10. The reflected light beam is sensed by a photosensor 7 and the radius of the light beam is measured from an electrical power and a time base and displayed in a display element 10b. In this way, the precision in measurement and the efficiency of measurement can be improved.

Abstract: PURPOSE: To position a gate recess to the bottom part of an active layer with precision by performing a non-selective etching up to a depth reference of gate recesses of two transistors, and performing simultaneous non-selective etching with two transistors up to the bottom part level of one transistor gate. CONSTITUTION: Non-selective etching is performed with an active layer 13, as far as a depth 62E equal to the depth difference between gate recesses 52D and 52E of two field effect transistors. Then, in an active layer 13, simultaneous non-selective etching is performed with first and second transistors down to a bottom part level 42D of the gate recess of the first transistor. Thus, a very accurate positioning of the bottom parts 52D and 52E of recesses housing gate contact-point pads 8D and 8E becomes possible. It is positioned without exceeding the allowable error in thickness, which is less than several crystalline single- molecule layers of a semiconductor material.

Then, input to a generation circuit 6 is performed after the output phi11 of the amplifier 24 goes to high, and signals phi8 and phi9 are generated. The signal phi11 is a signal to latch the amplifier 24, and is delayed following the delay of the output of the amplifier 24, and latches the output of the amplifier 24 correctly.

Title: Base isolation support
Inventor: TOYAMA KOTARO
IPC: E04H9/02
Filed: 1998-06-11
Abstract: PROBLEM TO BE SOLVED: To obtain a base isolation support having a restoring function by holding intermediate steel plates having spherical convex faces at both sides by upper and lower steel plates (base seat) having spherical concave faces through a plurality of steel balls to make a whole structure horizontally transferable. SOLUTION: A base isolation support 1 in which a number of bearing balls 4 are closely stuck to each other like a sandwich is fixed by anchors or the like between a base isolation structure 5 and a foundation 6. When a horizontal force acts in an earthquake or the like, upper and lower steel plates 2 (base seat) are moved (deformed) in the relatively horizontal whole directions so as not to impart any vertical displacement. When the horizontal action is released, the structure 5 is automatically restored by its own weight. Further, if the intermediate steel plates 3 are formed to be spherical concave faces and the upper and lower steel plates 2 (base seat) are formed to be spherical convex faces, the same effect can be obtained. In this way, a whole horizontal directional base isolation support device having a restoring function can be easily obtained.
