Title: Method and apparatus for encoding signal
Inventor: DEIRUKU YAN HERUMESU
IPC: H03M3/02
Filed: 1989-04-03
Abstract: PURPOSE: To accurately encode a signal by setting up the value of an angle formed by two straight lines intersecting with each other at each point of time as a 3rd signal. CONSTITUTION: When a 1st signal in which the pitch f0 of a sound signal is expressed as a function of time is expressed by a continuous curve and is defined as a 3rd signal in which the curvature (k) of the 1st signal f0 is expressed as the function of time, peak values appear on the curve (k) at time t1 , t2 ,..., t8 and an information block string is generated to encode the signal. In order to obtain the 3rd signal, an encoding unit determines two straight lines intersecting with each other at each of many points of time for sampling the 1st signal and passing the sample values of the 1st signal at plural points of time and determines an angle formed by the two straight lines. Consequently, accuracy can be improved and reproduction is not almost failed.

Title: Manufacture of printed wiring board
Inventor: YAMAKAWA MASAE
IPC: H05K3/06
Filed: 1997-04-01
Abstract: PROBLEM TO BE SOLVED: To form fine wiring by boring holes into a copper-plated laminated board and blackening the internal surfaces of the holes after metallization, and then, forming an etching resist by laminating a photosensitive dry film upon the surface of the copper foil, exposing the dry film to ultrasonic rays through a photomask, and developing the film and, finally, selectively etching off the copper foil. SOLUTION: After the surfaces of the copper foil 3 of 100 pieces of both-sided copper-plated laminated boards is blackened with a chemical on a substrate 4, a photosensitive dry film 2 is laminated upon the foil 3. Then 100 pieces of printed wiring boards 100 are formed by exposing the film 2 to ultraviolet rays, developing the film 2, and etching the film 2. The blackening is performed by dipping the foil 3 in a solution composed of sodium chlorite, sodium hydroxide, and sodium phosphate. The light passing through the transparent section of the photomask 1 at the time of exposure is not scattered, but mostly absorbed to the surface of the foil 3, when the light reaches the surface of the foil 3, because a black oxide formed on the surface of the foil 3 is black in color.  Therefore, the boundaries between light receiving sections and the other section become distinctive and fine wiring can be formed by transferring the shapes of the transparent sections.

Title: Start control method of keyhole welding
Inventor: HANEDA MITSUAKI
IPC: B23K10/00
Filed: 1978-07-07
Abstract: PURPOSE: To obviate the production of internal defects by stopping the travelling truck which has already moved at the start part until a keyhole is formed or for the specified time immediate before this.  
     CONSTITUTION: Holding time T s  of start current I s  is provided at the start part to make the shape 5 of reinforcement of weld smoother. At the same time, the travelling truck is temporarily stopped by the t time to allow penetration to increase during this time and make the keyhole easier to be formed, so that no defects such as inclusion of gas, etc. will be produced in the inside at the restarting of the travelling truck. This method reduces heat input given to molten pool because the travelling truck is held stopped from the start current I s  lower than the current value IH at the keyhole welding, hence the production of burn-through is suppressed.

IPC: G05F1/56
Filed: 1988-04-05
Abstract: PURPOSE:To control an output voltage based on the combination of the electrical states of both a start-up terminal and a power hold (PH) terminal by connecting a PH circuit to the start-up terminal, and holding the output voltage in spite of the electrical state of the start-up terminal while a current is taken out from the PH terminal. CONSTITUTION:When a regulated voltage is applied on an input voltage terminal 1 and the current over a prescribed value required for the start-up of a regulator from the start-up terminal 4, the current is supplied to a band gap type constant voltage circuit consisting of resistors (R4-R7), a diode D5, and transistors (TR) (Q6-Q8), then, the circuit is operated. A comparator detects the fluctuation of the output voltage, and drives a TRQ17 so as to keep the voltage of a Darlington-connected TR constant. The output voltage of the regulator can be held by continuing to take out the current. The regulator, when being driven once, supplies the current to the band gap type constant voltage circuit in spite of whether or not the current is taken out from the PH terminal 5, and operates the circuit, then, the output voltage of the regulator can be held.
