Title: Printed wiring board and manufacture thereof
Inventor: MATSUMORA SATORU
IPC: H05K3/12
Filed: 1989-02-06
Abstract: PURPOSE:To improve the solderability of a soldering land by exposing part of a wiring pattern inside the through-hole of a substrate and, at the same time, providing an overcoat layer on the surface of the wiring pattern opposite to the exposed part so as to use the exposed part as the land for soldering. CONSTITUTION:Part of a wiring pattern 3 formed by printing and sintering conductive paste is exposed inside the through-hole 2 of a substrate and the exposed part of the pattern 3 which is coated with a solder resist 5 and rich in metallic powder is used as a land 4 for soldering. Since the resistance value of the wiring pattern is minimized in such way, the solderability of the land 4 becomes excellent even when the rate of the metallic powder contained in the conductive paste is reduced. Therefore, the quality of this printed wiring board can be greatly improved.

Abstract: PURPOSE:To enhance the efficiency of measuring work and to secure the safety of a worker, by synthesizing the content of a digital value to be measured and a sound signal to output the same as audible sound. CONSTITUTION:An input signal 101 such as DC voltage, a DC current, AC voltage, an AC current or resistance is converted to the DC voltage signal 102 proportional to the input signal by an input signal converting circuit 2, and said voltage signal 102 is converted to a digital signal 103 by an A/D converter circuit 3 to be inputted to a digital processing circuit 4. The circuit 4 converts the signal 103 not only to the data adapted to a display circuit 5 to send out said data to the circuit 5 as display data 104a but also to be numerical value data 104b suitable for the processing due to a sound synthesizing circuit 6 to send out both data to the circuit 6. The circuit 6 forms a signal 106 representing the sound obtained from the measured value and unit (volt, ampre or ohm) shown by the data 104b. The signal 106 is outputted as sound heard by a human being by a sound output circuit 7. Further, the circuit 4 also performs the control of the start and finish of measurement, the time interval of sound output and the whole of the apparatus.

Title: Apparatus for manufacture of integrated circuit employing holography technology
Inventor: NIKORASU JIYON FUIRITSUPUSU
IPC: G03F1/00
Filed: 1989-02-03
Abstract: PURPOSE: To enable accurate reproduction of an image, by forming a holographic image of an integrated circuit onto a first recording medium by interference between an input beam passing through an object and a reference beam totally reflected on a glass plate surface, and similarly forming the image onto a second recording medium on a silicon thin piece by reproducing the image. CONSTITUTION: A second reference beam is supplied by a laser light source or mercury lamp 32, then passes through a prism 22, and advances to a glass plate 16 and hence into a first recording medium. The prism has such a structure that a light is internally totally reflected on the boundary surface between the recording medium and the air. The light source 32 continuously moves for scanning a holographic image onto the first recording medium. As a result, an image of an integrated circuit is gradually formed on a second recording medium provided on a silicon plate 30 from the holographic image recorded on the first recording medium, by interference between incident and reflected beams from the reproducing light source 32 for reference. Thus, a uniform holographic image may be provided on the entire surface of the coated silicon.

Title: Mechanical clamping device
Inventor: PIITAA POOTO
IPC: B23B31/40
Filed: 1980-03-05
Abstract: A mechanical clamping device, especially for clamping with high force of workpieces and tools, provided with clamping elements, characterised by an axial movable and helical rotatable conical wall (11, 21), against which rest similar bodies of revolution (12, 22), which are positioned on a changeable concentric circle of centre between two converging, concentric surfaces of revolution (13, 14, 23, 24), which are movable axially in respect of each other. Due to the extreme favourable behaviour of the rotating bodies of revolution (12, 22) which displace themselves at rotation in a helical way between the surfaces of revolution (13, 14, 23, 24), these surfaces are rolled and forced from each other. By this a favourable and equally distributed force transmission is obtained with a high degree of efficiency.

IPC: H04L27/14
Filed: 1991-02-21
Abstract: PURPOSE:To obtain a demodulation signal with high accuracy by adding a filter characteristic even to a couple of mixer circuits receiving one reception FSK signal with branching so as to intensify a filter function to an undesired signal component. CONSTITUTION:A mixer circuit consists of a single balance mixer 71 and a low pass filter 72. The single balance mixer 71 is provided with transistors(TRs) Tr1, TR2 in differential amplifier operation and a TR 3 connect to the emitter pair, and the low pass filter 72 consists of resistors R1, R2 and a capacitor C. Then a filter section in the mixer circuit attenuates an undesired frequency signal component in a received FSK signal and limits the frequency other than the desired frequency signal component with the substantial filter section located at its post stage. No intermodulation is caused even when an excess input of an adjacent frequency signal takes place by strengthening the filter function in this way.

Title: Structure of screw for detecting change of fluid from reflected light
Inventor: MORII TSUGUHIDE
IPC: G01F1/10
Filed: 1995-01-25
Abstract: PURPOSE: To enable a screw to detect the variation of a fluid with high accuracy and high reliability with a simple constitution by changing the light reflectance of the front and rear surfaces of blades constituting the screw. CONSTITUTION: The revolving motion of a screw 1 following the change of a fluid controls the quantity of light given to a photoreceptor element 9 owing to the difference in reflectance between the front and rear surfaces 2 and 3 of blades and a comparator 11 functions the output of the element 9 as 'ON' for the part having a high output potential and 'OFF' for the part having a low output potential. The rotating speed of the screw 1 following the variation of the fluid controls the time lag of the quantity of light made incident to the element 9 and the output pulse of the element 9 is outputted with different pulse widths.  When the time of the different pulse widths is measured and the number of pulse trains is counted, the absolute amount of the variation of the fluid can be measured without using any A/D converter and, at the same time, when the number of independent 'OFF' periods is counted, the number of 'ON' times within a unit time can also be measured.
