Title: Magnetic recording device and magnetic reproducing device
Inventor: HOSHI TERUO
IPC: G11B20/00
Filed: 1989-01-19
Abstract: PURPOSE:To record a sound signal and a sub-carrier signal on the single track of a magnetic tape without fail by setting the gap length of a recording head almost to (n+0.5)lambda when a recording wavelength, which is determined by a frequency (f) and a traveling velocity V of the magnetic tape, is assumed as lambda. CONSTITUTION:The sub-carrier signal of a prescribed frequency (f) is prepared. When the recording wavelength, which is determined by the frequency (f) and the traveling velocity V of the magnetic tape, is assumed as lambda and the gap length of the recording head is defined as an integer number (n), the condition of the (n+0.5)lambda is established and the sub-carrier signal is superimposed on the sound signal and recorded on the magnetic tape by using the recording head. When the wavelength lambda of the signal to be recorded on the magnetic tape is enough longer than a gap length (g), an output to be inverse proportional to the wavelength is obtained. When the wavelength lambdais equal with the gap length (g) and g/lambda is almost 1, there is no magnetization force between gaps and the output is made zero. Further, when the g/lambda is the (n+0.5)lambda, sensitivity can be obtained and the output is generated. Thus, the sound signal and sub-carrier signal can be superimposed and recorded on the single track of the magnetic tape.

Abstract: PURPOSE:To read even copied drawings efficiently and accurately in a plane orthogonal coordinate system, by providing a counter which computes absolute coordinate values from reference reading points and a counter which computes the amount of movement from a floating reference point. CONSTITUTION:The drawing 2 is fixed to a reading table 2. A cursor 3 which is moved on rails in the longitudinal direction of the reading table 1, and cursor 3' which is moved on the cursor 3 in the orthogonal direction are provided. The coordinates are read out by an industrial camera 4 which is arranged on a the cursor 3' under the control of a microcomputer 7 operated by an operating console 6. The intersection of straight lines 1X and 1Y of a mesh having an interval of 100mm. square, which is applied on the drawing 2 in advance, is used as the original point of the coordinate. Then the absolute coordinates (200.00, 0.00) of a point A is displayed on a counter LA. With the point A as the floating reference point, the coordinates (20.50, 5.60) of a point P1 are displayed on a subcounter LB. The coordinates of the point P1 are obtained as a sum. The same procedure is applied to other points. Thus even copied drawing can be read efficiently and precisely.

Title: Circuit for electronic time piece
Inventor: KITANO MASUO
IPC: G04G3/02
Filed: 1983-01-25
Abstract: PURPOSE:To realize a small high precise electronic time piece at low cost, by setting the final frequency dividing ratio of a frequency dividing circuit by logically changing the phase of the signal inputted to the initial stage of the frequency dividing circuit. CONSTITUTION:The numeral 29 is a 1/2 frequency dividing circuit with a setting function due to a falling trigger. When a logical speed setting switch is turned OFF, a set signal S26 becomes low and the output signal S29 of the 1/2 frequency dividing circuit changes at the falling time of S15 and the signal S29 is inputted to an exclusive OR circuit 30. The circuit 30 transmits the signal of S7 while reversing the same when the signal S29 is high. Therefore, the signals of S7 and S8 become equal. On the contrary, when the signal S29 is low, S3 and S4 come to reversed signals. By utilizing the feature of this circuit, a pulse signal is inputted to the circuit 29 at a constant cycle to cyclically repeat the high and low of the signal S29 and the logical change of speed can be performed. Because the signal S29 is low in a section (a), S7 and S8 are reversed signals. At the point of time when S15 becomes low, a signal enters a section (b). When S15 becomes low, S29 becomes high and the signal of S8 is reversed while the signals of S7 and S8 are the same.

Title: Two-wavelength energy measuring apparatus
Inventor: YAMAMOTO JUN
IPC: G21B1/03
Filed: 1987-01-19
Abstract: PURPOSE:To simultaneously measure the energy of the laser beam converted by a wavelength converting element and that of laser beam not converted by said element, by separating the laser beam having two wavelengths passing through the wavelength converting element into two directions using a dichroic mirror. CONSTITUTION:When laser beam having a certain wavelength is incident on a wavelength converting element 1, laser beam converted in its wavelength and the incident laser beam are together emitted. These laser beams having two wavelengths are simultaneously condensed by a condensing lens 2 and allowed to be incident on a dichroic mirror 4 while the intensities thereof are weakened by an optical filter 3. Since the dichroic mirror 4 reflects only laser beam having a certain wavelength and transmits laser beam having other wavelength, the energy of the laser beam converted by the wavelength converting element 1 and that of the laser beam not converted by said element 1 can be simultaneously measured by energy measuring sensors 5, 6 each using a biplanar photoelectric tube measuring the energies of respective wavelengths.

Title: Etching method for insulating protection film of semiconductor substrate
Inventor: NAKAMICHI TADAHIRO
IPC: H01L21/3065
Filed: 1982-01-26
Abstract: PURPOSE:To remove stains from an insulating protection film and to improve the  shape of a stage, by making a window in the film by a dry-etching processing, and then  subjecting the same to immersion processing with an HF water solution. CONSTITUTION:The result of analysis of a semiconductor substrate just after a window  is opened in an insulating protection film by a dry-etching processing is indicated by a broken line 1, while the result of analysis of the surface of the semiconductor substrate which is subjected to an immersion processing for a short time thereafter with an HF  water solution is indicated by a broken line 2. The comparison between these broken  lines 1 and 2 shows that C, F, Mg, Na, K, etc. are reduced more in the substrate subjected to the additional immersion processing than in the substrate not subjected thereto, and that the additional immersion processing with the HF water solution is effective  for removing stains on the surface. In practice the substrate subjected to the immersion processing with the HF water solution is excellent in the bonding property with an  Al film or an Al alloy film, the corners of a staged part are chamfered, and the  coating property of the Al film or the Al alloy film is also excellent.

Title: Silver peroxide battery
Inventor: YOKOYAMA TAKEISA
IPC: H01M4/08
Filed: 1982-01-25
Abstract: PURPOSE:To prevent a denatured layer from being broken during the assembly of a silver peroxide battery by heating a silver peroxide pellet having almost the same diameter as the inner diameter of a positive can in the positive can so as to provide said pellet with the denatured layer, and pressing thus treated pellet so as to make a positive active material. CONSTITUTION:A silver peroxide pellet 4'-1 having almost the same diameter as the inner diameter of the bottom surface of a positive can 1, is formed by pressing silver peroxide powder. Next, the pellet 4'-1 is inserted into the positive can 1, the top diameter of which is slightly larger than its bottom diameter, and subjected to heat treatment so as to produce a denatured layer 4'-2 by converting about 10% of silver peroxide located at the surface of the pellet 4'-1 into silver oxide. Next, after the packed density of the pellet 4'-1 is increased by pressing, a porous conductive layer 6 is placed on the pellet 4'-1. After that, a silver peroxide battery is constituted by the combination of a separator 5, a negative active material 7 and the like. As a result, since the battery can be assembled without breaking the denatured layer 4'-2 formed only at the surface of the pellet 4'-1, a battery which causes no two-step electric discharge and has stable characteristics can be obtained.
