Patent JP-S6317428-A (JP)
Title: Bragg cell
Inventor: MISU KOICHIRO
IPC: G02F1/1339
Filed: 1986-07-08
Abstract: PURPOSE:To analyze an even high frequency with high accuracy by using a bulk wave which is propagated nearby the surface of a piezoelectric body substrate as an elastic wave to be excited by reed screen type electrodes, and arranging those reed screen type electrodes which differ in excitation frequency so that the distance to a light surface wave propagation path is varied. CONSTITUTION:Such a crystal direction that the bulk wave 6 propagated nearby the surface of the piezoelectric body substrate 1 is excited by the reed screen type electrodes 3 arranged on the substrate 1 is selected to provide an optical surface waveguide 2 on the surface of the substrate, and the light surface wave 5 is propagated therein. Two electrodes which differ in excitation frequency are arranged as the electrodes 3 so that their distances to the light surface wave 5 are different. The bulk wave 6 increases in depth-directional distribution with its propagation distance, so the distance between the electrodes 3 and the propagation path of the light surface wave 5 is so settable that the depth- directional distribution of the bulk wave 6 on the propagation path of the reed screen type electrodes 5 has necessary enough depth to diffract the light surface wave 5. Consequently, refracted light 5' is intense even at a high frequency.

Title: Circuit for separating luminance signal and chrominance signal
Inventor: ISHII SATOYUKI
IPC: H04N9/78
Filed: 1992-06-22
Abstract: PURPOSE:To attain Y/C separation of a video signal having a vertical uncorrelation component with simple configuration. CONSTITUTION:A video signal whose band is limited to a horizontal high frequency by a BPF 41 is delayed by 1H at a 1H delay circuit 42 and the delayed signal is given to a median value circuit 43. The median value circuit 43 receives an input and an output of the 1H delay circuit 42 and a reference potential and obtains a median of the three inputs and outputs the result to a nonlinear circuit 45. The nonlinear circuit 45 sets a component below a prescribed level of the median output to 0 and outputs the result to an adder 44. A vertical low frequency component of a chrominance signal band is given to the adder 44 from the nonlinear circuit 45 and the adder 44 subtracts an output of the nonlinear circuit 45 from the output of the BPF 41 to obtain a color output. An adder 11 subtracts an output of the adder 44 from the input of the BPF 41 to obtain a luminance output. The Y/C separation of the video signal having the vertical uncorrelation component is attained with a simple circuit employing one 1H delay circuit and one median value circuit.

Title: Preparation of miller wafer
Inventor: OOSAWA AKIRA
IPC: H01L21/304
Filed: 1983-09-07
Abstract: PURPOSE:To sufficiently reduce the concentration of impurities in a wafer with minimum change of conventional processes, by thermally oxidizing the surface of a silicon wafer obtained by slicing an ingot before polishing the wafer. CONSTITUTION:A silicon wafer is heat-treated at an elevated temperature under oxidizing atmosphere, whereby an oxide layer (SiO2 layer) is formed on the surface of the silicon wafer. Mechanical distortion occurs on the interface between this oxide layer and the silicon crystals, and this distortion getters impurities such as heavy metals. Subsequently, the oxide layer is removed, for example by treating with fluohydric acid (HF), whereby undesirable impurities gathered on the interface of the wafer can be removed. In such a manner, the concentration of undesirable impurities such as copper, iron, nickel, chromium, sodium or the like can be reduced, in the stage of a wafer, by one tenth or more, so that a miller wafer with high purity can be obtained.

Title: Main-frequency removal unit
Inventor: SATOU HIROKAZU
IPC: H03H17/00
Filed: 1978-12-27
Abstract: PURPOSE:To remove a noise component in a signal easily and automatically, by specifying an unneeded signal component frequency from an output signal level by continuously scanning a removed frequency component by a band-pass filter. CONSTITUTION:The moment a signal is inputted to filter circuit 1, scan change- over circuit 3 supplies scan control signal Sc from control circuit 4 to scanner circuit 2. Circuit scans continuously on circuit 1 by specified frequency information fd, so that the output of circuit 1 will vary in sequence as much as a removed frequency fd component. Comparator 6 exercises a supervision over this and every time a level lower the set value of comparison level setting circuit 7 is detected, a pulse signal is sent out to counter circuit 8. When the count value of circuit 8 is not less than two, the set value of circuit is decreased via circuit 4 to repeat the scan by specified frequency fd until the count value of circuit 8 reaches one. When the count value becomes one, the set value of circuit 7 is fixed and circuit 3 selects signal Sv from minimum-level detection circuit 5 to set it to circuit 1 as specified frequency fd, thereby minimizing the output signal level.

Next, the sintered body 2 is impregnated with an active material by a well known method by using nickel nitrate solution and cadmium nitrate solution. After the impregnation, formation is carried out so as to obtain a positive nickel plate and a negative cadmium plate.

Title: Cassette type magnetic tape unit
Inventor: FUJISAWA SHINOBU
IPC: G11B15/00
Filed: 1990-06-21
Abstract: PURPOSE:To prevent damage for reel driving shaft when inserting a cleaning cassette by stopping the rotation of a reel motor when e cleaning cassette is inserted. CONSTITUTION:A cleaning cassette 150 is not equipped with holes for inserting reel driving shafts 29 and 30 on one main face 151 and another main face 152. Since the reel driving shafts 29 and 30 does not rise up to be engaged with hubs 10 and 11 even when the cassette is inserted, the loading end signal of the cleaning cassette 150 can be obtained. A control circuit 76 transmits a low-level reel motor drive block signal to a line 162. A control driving circuit 140 is correspondent to the output of an AND gate 242 without directly responding to a drive signal from a terminal 241. Since the driving signal terminal 241 and the line 162 are connected to the AND gate 242, the drive of reel motors 27 and 28 is inhibited while applying the block signal from the line 162 to the AND gate 242. Thus, the rotation of the reel driving shafts 29 and 30 is inhibited while loading the cleaning cassette 150.

Abstract: PURPOSE:To reduce the length of a connecting line, to simplify the manufacturing process of the title instrument and to prevent thermal interference between a circuit element and heating element by providing a sensor substrate, heat radiating plate, and hybrid IC. CONSTITUTION:The heat generated from a transistor and reference resistance is absorbed by and radiated from heat radiating plates 11a and 11b.

In addition, the heat generated from a hybrid IC 18 is also transmitted to the plates 11a and 11b through a connecting pin and taking-out electrode valve and radiated from the plates. In addition, since the transistor and reference resistance are provided on the same sensor substrate 3 together with a heating element and temperature compensating resistance, connecting line among them can be made shorter and wiring can be made easier and as a result, occurrence of noises can be reduced accordingly.
