Title: Drive method of optical reader
Inventor: MURATA TAKAHIKO
IPC: H04N1/107
Filed: 1984-03-15
Abstract: PURPOSE:To read at the same intervals without fail even when the period of a read start signal changes by setting an integral period independently of the period of the read start signal. CONSTITUTION:A signal 13 which is delayed by a constant period T's from a read start signal 10 is generated. A signal 14 obtained by ORing the signal 13 with the start signal 10 is set to a read start signal of an optical reader. Since the delaying period T's is a sum (T's=T+t) of an access time (t) (constant) and an integral time T, the latter is always constant. Thus an object to be read can be read out with the same sensitivity without fail because the integral time T becomes always constant independently of a read start period Ts. A dummy output A is distinguished from a normal output B by sampling an output B after the period T's from the read start signal 10 or by sampling the output B at the moment the shifted signal 13 is received.

IPC: C04B41/63
Filed: 1998-03-02
Abstract: PROBLEM TO BE SOLVED: To provide the concrete which is prevented from being deteriorated and requires no maintenance by applying to concrete, a coating technique that enables retention of an air film on the concrete surface in contact with water. SOLUTION: In this production, when a concrete flat plate 50 on which a coating layer 51 capable of retaining an air film on the concrete surface in contact with water is formed, is placed under water 53 from a place in the air, the concrete flat plate 50 is brought into the water 53 in such a state that air is retained on the surface of the coating layer 51, to form an air film 52 on the surface of the coating layer 51. Further, air is introduced and incorporated into the air film 52 through a small- diameter pipe 54 to expand the air film 52 as shown by a dotted line in the figure. Therefore, the coating layer 51 has such characteristic properties that the thin air film 52 can be retained under water and air supplied from the outside can be incorporated into the air film 52.  Thus, an always stable structural material or high strength material made of this concrete, in which no slimy matter due to organic matter, mold, algae, etc. is formed on the surface even when the surface is brought into contact with water drops or a continuous or discontinuous water stream or submerged in water and further, corrosion under the circumstances of high humidity and peeling/ swelling of the surface, cracking of the base material, etc. in a cold district are not caused, can be obtained.

Filed: 1995-03-09
Abstract: PURPOSE: To perform an extent of control over such a rock bed stability as being high in reliability by embedding a pressure transducer into a boring hole made in a rock bed, and measuring excessive pore water pressure attending upon a base rock deformation during excavation. CONSTITUTION: A boring hole H is made in a rock bed G at a survey spot in and around the constructing spot of an underground structure. Next, a pressure transducer 2 is set up in a measuring position in this boring hole, filling up the circumference with sand 3 serving as a filter's function, and both the lower and upper parts are sealed up by means of two mortar parts 1 and 1'. In succession, observation of the hydraulic pressure measured value attending on base rock excavation is carried out via an output cable 4. In addition, while excessive pore water pressure shows an increasing trend at all times, it is so judged that 'there is no problem in stability'.  If the excessive pore water pressure is turned to a decreasing trend from the increasing one, the rock bed G at that section is judged to be in a state of half deformation in a destructed strain condition or in a state of producing half the maximum shearing stress and a proper countermeasure is studied.

Filed: 1979-04-23
Abstract: PURPOSE: To provide watch glass strong against force applied from the top face and therefore strong in use by a method wherein inorganic glass for watch is curved at the center section and dipped into molten salt containing potassium nitrate.  
     CONSTITUTION: A watch cover glass 1 is fixed in a fixture 2, supported at the periphery of glass bottom face, and is pressed at the center section of the top surface. This applies compressive stress on the top surface and tensile stress on the bottom face. The so fixed glass is preheated, dipped into molten salt and held there, then cooled in air, washed with water to remove KNO 3 , is dried, and removed from the fixture. In this process, tensile stress in the glass bottom face allows faster ion-exchange rate than that in no stressed condition. This results in more of potassium ions exchanged with sodium ions and produces compressive stress higher at the bottom than the top surface, in condition the glass is removed from the fixture after chemical reinforcing process.
