Title: Magnetic recording/reproducing device
Inventor: KATSUKI MANABU
IPC: H04N9/81
Filed: 1988-04-15
Abstract: PURPOSE:To suppress the decrease of resolution and to enhance an SN ratio by outputting the chrominance signal of a restored base band through a noise decreasing means and outputting a luminance signal from 8 restoring means and the chrominance signal with approximately corresponding to each other. CONSTITUTION:A reproducing system time base processing circuit 17 executes a time base processing contrary to that at the time of recording, and restores a Y signal to be the luminance signal and a Comega signal and a CN signal to be both chrominance signals. The noises of the restored Comega signal and the restored CN signal are respectively decreased, and the signals are inputted through noise decreasing circuits 18 and 19 respectively having a constant delay time tau1 for frequencies to a reverse matrix circuit 20. In a reproducing system time base processing circuit 17, the restored Y signal delays the reading of the Y signal to the Comega signal and the CN signal, for example, when the Y signal, Comega signal and CN signal written into a memory are read. Thus, the restored Y signal is outputted by being delayed for the constant time t, with respect to the Comega signal and the CN signal, and inputted to the reverse matrix circuit 20 conforming to the delay time tau1 of the noise decreasing circuits 18 and 19.

Title: Method for detecting metallic contaminant in sub-micron silicon surface layer of semiconductor
Inventor: LOWELL JOHN K
IPC: G01N21/95
Filed: 1998-04-03
Abstract: PROBLEM TO BE SOLVED: To obtain a simple method by which metallic contaminants in the sub-micron silicon surface layer of a semiconductor wafer can be detected quickly. SOLUTION: Metallic contaminants in the sub-micron silicon surface layer of a semiconductor wafer 105 are detected by obtaining the frequency distribution plot of the wafer 105, by irradiating the wafer 105 with a photon flux using high injection surface photovoltaic method. First and second optical chop frequencies are selected from the frequency distribution plot, and the wafer 105 is irradiated with a photon flux at the first optical chop frequency. Then the charge distribution on the surface layer at the selected chop frequencies and a surface barrier height map indicating the values of the charges are generated. Then the surface layer of the wafer 105 is irradiated with the photon flux at a second optical chop frequency, which is different from the first chop frequency, and a second surface barrier height map is generated.  Then the wafer 105 is annealed, and the frequency distribution plot and surface barrier height map of the annealed wafer are generated by repeatedly performing the processes on the annealed wafer 105. The metallic contaminants in the sub- micron surface layers of the wafer 105 are measured by comparing the frequency distribution plot and the surface barrier height map of the annealed wafer 105 with those of the wafer 105 before annealing.

Title: High frequency receiver
Inventor: KOGURE TAKUYO
IPC: H04B7/185
Filed: 1984-05-10
Abstract: PURPOSE:To control appropriately the oscillation frequency at the time of transmission through a long transmission cable by frequency-modulating an oscillation frequency control signal of a partial oscillator at the side of a station selection circuit and supplying it to a frequency converter. CONSTITUTION:After a control signal 10 for controlling an oscillation frequency of a partial oscillator 4 at the side of a frequency converter 21 is modulated in terms of frequency, it is transmitted through a transmission cable 15. At this time, a control signal 28 subjected to frequency modulation hardly changes in terms of frequency itself when the cable 15 becomes longer and a voltage drop caused by its resistance loss becomes larger. Accordingly the signal 10 without fluctuation with respect to the signal 10 obtained at the side of a station selection circuit 22 can be always given to the oscillator 4 of the converter 21 after said signal is demodulated at the side of the converter 21. Thus a high frequency receiver can execute the stable selection action of a station irrespective of the length of the cable 15.

SOLUTION: When a drying shelf 19 is set in a feed opening 3 of clothes as shown in the drawing, the hinge 19a of the drying shelf 19 gets into contact with a shelf-detection sensor 22 installed at the feed opening 3 of clothes and constituted of a piezoelectric element or the like and signal currents flow to detect the drying shelf 19. This detected signal is processed by a controller to drive a drive motor 18-1 for the shutter and open the shutter 18 by operating a drive cam 18-2 for the shutter. To the contrary, when the drying shelf 19 is removed from the feed opening 3 of clothes, the shutter 18 is closed. In this way, when the drying shelf 19 is set at the opening, the shutter is automatically opened and when it is removed from the opening, the shutter is automatically closed to execute a partly exhausting type drying.

Title: Solder paste and electronic circuit device formed by using the same
Inventor: HARADA MASAHIDE
IPC: B23K35/363
Filed: 1996-04-15
Abstract: PROBLEM TO BE SOLVED: To suppress the residual voids in the solder paste connecting parts of electronic parts and a circuit board by setting the temp. at which the solvent contained in the solder paste gasfies at a prescribed temp. range with respect to the m.p. of the solder powder included in the solder paste. SOLUTION: The printed wiring board 1 is first printed with solder paste 3. Next, pins 4 for solder connection of the electronic parts are inserted to the circuit board. Next, heating is executed. The temp. at which the solvent contained in the solder paste 3 to be used gasfies is set at the prescribed temp. range with respect to the m.p. of the solder powder contained in the solder paste 3 and, therefore, air bubbles are less generated at the temp. at which the solder melts or below. Next, the solder melts when the temp. attains 183 deg.C. The flux and solvent, etc., are low in sp.gr., and, therefore, float to the upper part of the solder. The solvent foams thereafter. Even if the solvent foams at the point of this time, the foaming occurs in the upper part of the solder and, therefore, the stagnation of the bubbles as voids in the solder does not arise.
