Title: Automatic cutting system
Inventor: TAKAGI MIKIO
IPC: G03F1/00
Filed: 1988-08-19
Abstract: PURPOSE:To extract the contour of an objective picture in a fully automated state by considering that cutting lines exist in a block, the degree of separation of one plate of which exceeds a set value, and binarizing the block. CONSTITUTION:The picture data of a picture 11 to be processed are divided into fixed blocks of, for example, F1-F30 and a discriminating and analyzing method is applied to each plate (C, M, and Y plates) of each block. When the degree of separation of the method exceeds a set value on at least one of the plates, the block is binarized by considering that cutting lines exists in the block. The binarizing process of the discriminating and analyzing method is a method which finds the variance in and between each class and uses the density value at which the inter-class degree of separation becomes the maximum as the slice level (k) of the binarization by considering that a picture can be divided into two classes. Therefore, the contour of an objective picture can be extracted in a fully automated state.

Abstract: PROBLEM TO BE SOLVED: To suppress a frequency change at an environmental temperature outside the usual operating temperature by generating a temperature correction signal based on the environmental temperature and supplying a current based on the signal to a coil on a cavity resonator. SOLUTION: An output of a voltage controlled crystal oscillator VCXO 20 is subjected to phase modulation at a frequency synthesis circuit 21 based on a low frequency f1 from a servo circuit 22 and generates a phase modulation wave signal. The phase modulation wave signal is fed to a diode 23, from which a microwave output is generated and a microwave excites a cavity resonator 14. A C magnetic field coil 18 to generate a magnetic field is wound on a gas cell 15 of the resonator 14 and a C magnetic field current circuit 31 supplies a current to the coil 18. Then a temperature detection circuit 34 in the circuit 31 provides an output of a detection signal of a voltage Vr in response to the environmental temperature detected by a temperature sensor 32 and gives the signal to comparators 35, 36 and a correction circuit 37.  Then the comparator 35 provides an output of a low level signal when the environmental temperature is less than the operating lower limit temperature at in excess of the operating upper limit temperature.

Title: Phase comparator
Inventor: YATSUYAMA HIRONORI
IPC: H03K5/26
Filed: 1992-08-03
Abstract: PURPOSE:To prevent production of a through-current of an output section of the phase comparator without need for detailed calculation of a delay time for a logic circuit section by forming a flip-flop circuit with two NAND circuits generating an input signal to each gate section of P-channel and N-channel TRs connected in series. CONSTITUTION:A level of an input to and a level of an output from a NAND circuit E3 go respectively to an L and an H with a leading of an input waveform D inputted to an inverter E1 in a timing T1. An output of a delay circuit E12 goes to an H, an input to and an output from a NAND circuit E9 go respectively to H and L. Thus, a gate of a P-channel TR E14 is conductive and an output of an output section E16 of the phase comparator goes to H. An output of the NAND circuit E3 goes to H in a timing T2 and outputs of NAND circuit E9, E11 are unchanged and the output section E16 keeps the state in the timing T1. On the other hand, the circuit E3 goes to L before the circuit E4 goes to L in a timing T3 a circuit E10 goes to H and even when an output of a delay circuit E13 is inputted to the circuit E11 before the circuit E10 goes to L, since an output of the circuit E9 is inputted to the circuit E11, so long as an output of the circuit E9 is at an L, the output of the circuit E11 does not go to L. The operation when the input waveform C rises earlier than a waveform D is similar to above.

Title: Manufacture of semiconductor element for forming oxide film pattern having gentle inclination
Inventor: KIN SOKI
IPC: H01L21/302
Filed: 1998-07-22
Abstract: PROBLEM TO BE SOLVED: To enable formation of an oxide film pattern the lateral side of which has a gentle degree of inclination, by selectively etching a multilayered oxide layer, and thus forming an oxide film pattern with an inclined sidewall. SOLUTION: After a first oxide film 302a is evaporated on a semiconductor substrate 301, heat treatment is carried out at a temperature of 200-1400 deg.C, and a second oxide film 302b is evaporated on the first oxide film 302a. In this case, the evaporation temperature of the second oxide film 302b is lower than the evaporation temperature of the first oxide film 302a. The lateral inclination of first and second oxide film patterns to be formed after etching is very moderate. This form is made because the second oxide film 302b is etched faster than the first oxide film 302a. That is, the first oxide film 302a and the second oxide film 302b of heterojunction are different in structure and physical characteristics.  When these oxide films are etched by using the same etchant, the sidewalls of these oxide films have a very gentle inclination because the etching ratios differ from each other.
