Patent JP-2000323565-A (JP)
Title: Manufacture of semiconductor device and semiconductor device
Inventor: MORINO YASUNORI
IPC: H01L21/762
Filed: 1999-05-13
Abstract: PROBLEM TO BE SOLVED: To prevent the formation of a recess at an edge of a buries oxide film by forming the buried oxide film for filling a groove formed in a silicon substrate so as to be wider than the opening of the recess on the surface of the silicon. SOLUTION: An underlying oxide film 2 and a silicon nitride film 3 are laminated on a silicon substrate 1. A recess 13 is formed by etching. The width of the opening of the film 3 is made larger than the opening of the substrate 1 by anisotropic etching. After depositing a buried oxide film 11 over the entire surface, a portion of the film 11 which is on the film 3 is removed. Thus, the silicon nitride film which is extended over the film 2 is formed. The film 2 is then removed by wet etching. This prevents the formation of recesses at edges of the film 11, and hence can suppress the reverse narrow channel effect of a transistor.

Title: Electrode foil inserting position detector for capacitor-type bushing
Inventor: OGAWA TAKESHI
IPC: G01D5/12
Filed: 1978-10-30
Abstract: PURPOSE:To eliminate the misworking and thus to increase the working performance by stopping the driving mechanism which turns the central conductor when the coincidence is obtained between the number of the pulse signals sent from the winding frequency detection part and the set winding frequency. CONSTITUTION:When central conductor 4 is turned by the driving device, the thin leaf insulating component 2 is wound round conductor 4. And at the same time, casing 5 is turned, and accordingly dog pins 6 attached to casing 5 in the 10-equal distribution way operate limit switch 7 with every 1/10 turns. Thus the signals of 10 pulses per turn are supplied to preset counter 8. Counter 8 sends the stop signals to the driving mechanism which turns conductor 4 when the input pulse number reaches the set winding frequency to secure an automatic stop of the turn for conductor 4. Thus electrode foil 3 is inserted at that moment to ensure a simple detection for the insertion position. In such way, the working mistake can be eliminated to secure a high-efficiency working.

Title: Air conditioner
Inventor: NAMIKATA RUMI
IPC: F24F1/00
Filed: 1988-06-01
Abstract: PURPOSE:To allow the cold/hot air outlet of air conditioner to be used as a pleasant interior design object by disguising same as interior design objects such as a tree or flower box, etc., by forming the cold/hot air passage to the outlet with several pipes. CONSTITUTION:Under the cooling mode operation, the room air is taken in by a fan 2 to exchange heat with refrigerant in a heat exchanger 3, and the cooled and dehumidified air is delivered from the unit 1. A pot 4 for an artificial tree 6 is attached to the air outlet. The cold air passes through the pipe disposed in the center of the pot 4, and the cold air 92 is delivered from holes drilled in the pipe 5 to cool the room. In this case, a cold/hot air reversing valve 10 is open. Under the heating mode operation, on the other hand, the valve 10 is fully closed or half closed. Therefore, the hot air 93 delivered from the unit 1 is inhibited to flow upwardly, but is blown near to the floor out of holes in the pot ahead of the valve 10. By operating the valve 10, cold air can be delivered from above, and hot air from under.

IPC: B23K9/29
Filed: 1999-05-13
Abstract: PROBLEM TO BE SOLVED: To obtain an electric torch of a wire bonder, wherein melting-cutting position of a wire can be stabilized by specifying an electric discharging point of the torch. SOLUTION: An electric torch 1 for melting and cutting a wire 6 fed from the top of a capillary 7 by the electric discharge energy is composed of a circular columnar Pt conductor 2, a tubular zirconium oxide nonconductor 3 which houses and covers the conductor 2, and a circular discharge position control hole 4 having an opening area of 0.05-0.2 mm2, formed at the top end of the nonconductor 3. The entire side surface of the conductor 2 is covered with the heat-resistant nonconductor 3, at the top end of which the discharge position control hole 4 is formed to regulate the discharging direction, so that this results in no discharge occuring anywhere on the electric torch 1 surface. Thus the melting-cutting position of the wire 6 is stabilized to suppress and prevent variation.

Title: Control word protecting circuit
Inventor: KOBAYASHI MASAHARU
IPC: G11B20/10
Filed: 1980-09-26
Abstract: PURPOSE:To prevent a control signal from being outputted as a data, by detecting a program searching signal, etc. in a control signal block, and applying it to a prescribed error detection word detecting output, so that the control signal block is not inputted to a data block. CONSTITUTION:A data 74 is inputted to a program searching signal detecting circuit 75, and whether it is a control signal block or a data block is decided. A counter 77 starts counting from the timing of a vertical synchronizing signal, and generates a gate signal 82 through a decoder 84. By a 2 input AND circuit 83, a detecting circuit output 76 coincides with the gate signal 82. A coincidence output 84 takes the sum with an error detection word detecting result 85 by a 2 input OR circuit 86. A sum output 87 becomes an error signal. In case when the error detection word detecting result 85 is an error, all become an error signal, but even if it is not an error, when a program searching signal has been detected during the period of H, the gate signal 82 becomes an error signal. By such a constitution, it is prevented that a control signal is outputted as a data.

Abstract: PURPOSE:To quickly obtain well-focussed high-quality synthetic-aperture radar images, by finding real Doppler changing ratios on the basis of the distance between effective center frequencies, positional deviating quantity between look image data, and initial Doppler changing ratio. CONSTITUTION:A two-look image correlation counting means 15 counts the correlation between two partial images by shifting the positions of two images one picture element by one picture element and outputs a positionally deviating quantity and correlation value to a maximum correlation position searching means 16, and thus, the positionally deviated quantity (d) which gives the maximum correlation value is found. Moreover, the output of a range coverture correcting means 7 is sent to a power spectrum calculating means 20 and the intensity distribution in the frequency area is calculated. A look effective center frequency calculating means 21 finds the effective center frequency of each look from the intensity distribution and calculates the distance lE between the effective center frequencies. A Doppler changing ratio correcting means 17 finds a real Doppler changing ratio Ka from the positionally deviating quantity (d), distance lE between the two look effective center frequencies, and initial Doppler changing ratio K'a and performs azimuth-compressing processes on all image data by using this value Ka.
