Title: Distance measuring device
Inventor: KITA KOUICHI
IPC: A61B5/08
Filed: 1979-09-28
Abstract: PURPOSE: To ensure an easy measurement of the distance for a travelling object, by dividing the light sent from the spot light source into two beams, detecting these beams by the image pickup element and thus measuring the distance between the two spots to measure the distance up to the light source.  
     CONSTITUTION: The light from the light emitting diode 7 is divided through two slits S 1  and S 2  to be caught by the solid state pickup element 9 as the two spots for output. Thus the distance l from the point P to the surface C of the pickup element is shown as l=a.l 0 /(a-a 0 ), where P is the position of the light emitting diode, a 0  is the distance between S 1  and S 2 , l 0  is the distance between the slit and the pickup element and (a) is the distance between the intersections of the two pieces of the divided beams and the surface C of the pickup element respectively. The light hits the element 9 at two areas, and thus two units of pulses V 1  having the prescribed interval T are delivered from the output of the element 9. These pulses receive a signal process to carry out the measurement of distance for a travelling object.

Title: Turbine flowmeter
Inventor: INOUE SEIJI
IPC: G01F1/12
Filed: 1998-05-07
Abstract: PROBLEM TO BE SOLVED: To obtain a turbine flowmeter by which the flow rate of a fluid can be measured in a wide measuring range and with high accuracy without generating a failure or the like by a method wherein the pitch angle of the blade of a propeller is changed by a hydraulic pressure according to the flow rate of the fluid. SOLUTION: The flow rate of a fluid 02 is measured by the speed of rotation of a propeller 7 which is arranged and installed inside a pipe 01 in which the fluid 02 whose flow rate is to be measured flows. A hub 6 is installed in the axial center part of the pipe 01 so as to be supported by a shaft support 04 and a shaft support 05 inside the pipe 01. A plurality of blades 3 are installed on the outer circumferential face of the hub 6 so as to constitute the propeller 7. The blades 3 are made variable by a pitch-angle changing means which is installed inside the hub 6, and they can be changed in such a way that an angle of elevation with reference to the flow of the fluid 02, i.e., a so-called pitch angle, becomes a magnitude corresponding to the flow rate. A working fluid which is supplied from a hydraulic-pressure supply source 14 is supplied to a pitch-angle changing means.  Thereby, it is possible to obtain a turbine flowmeter in which, even when the flow rate is changed largely, the overspin of the propeller 7 is not generated, which prevents a failure and whose reliability is increased.

Title: Ceramics circuit board
Inventor: YANO SHINSUKE
IPC: H05K3/46
Filed: 1988-05-23
Abstract: PURPOSE:To make it difficult to generate migration and to form fine patterns, by roughening the surface of a glass 1 filler substrate firable at 800-1100 deg.C in an acid solution of pH1-4, and by forming it into a surface circuit board by use of plating with Cu conductor or the like. CONSTITUTION:A ceramic substrate 1 containing Ag based conductor 2 is subjected to electroless plating 5, electroplating 6, and soldering 12 thereon. As a ceramic board, only the surface of a glass 1 filler low-temperature firing (800-1100 deg.C) substrate is immersed in a-acid solution of pH1-4 for uniform roughening under gentle conditions, then, fine circuit patterns are formed on the substrate surface by plating with Cu, Ni, or Au conductor difficult to generate migration and by their combination. Particularly, only Cu conductor or the combination of Cu conductor, Ni, and Au is preferable from the view of cost and conduction resistance. If the solution used for surface roughening is pH lower than 1, glass in the substrate melts too excessively to hold intensity. If pH is higher than 4, the surface roughening is insufficient so that the conductor does not turn stronger in adhesion.

Title: Start-point detection system for transfer data
Inventor: MATSUMURA NOBUHIRO
IPC: G06F3/00
Filed: 1977-10-21
Abstract: PURPOSE: To secure correct detection of the data start-point by dividing the sink byte into more than one bit group which are distant by a fixed bit with each other and delivering the output when an agreement is detected for at least one set of the bit pattens.  
     CONSTITUTION: The sink byte is divided into, for example, the first bit group of the upper 5 bits and the second bit group of the lower 5 bits, and each of the bit patterns is set to "10101" and "11001" respecitvely. These bit pattrns are then shifted in sequentially to shift register 1 through the bit pattern detector circuit. The bit patterns of the first and second bit groups are detected via AND gate 2 and 3 to be put into OR gate 4 when the sink byte is shifted in completely. Accordingly, the sink byte is detected if at least eigher one of the bit patterns is normal, avoiding the effect of the error due to the local defect of the medium or the like. Thus, the start- point detection signal can be delivered in a correct way
