Title: Image pickup device
Inventor: SUZUKI MASAHARU
IPC: H04N5/357
Filed: 1989-07-06
Abstract: PURPOSE:To prevent moire stripes from being generated while suppressing degradation in the contrast of an photographed picture by controlling the space frequency characteristic of an optical low-pass filter to a proper value by a control value to be outputted by a control value output means based on a component in an image pickup signal. CONSTITUTION:An image pickup element 3 inputs the light of an object through an optical low-pass filter 2, which changes the space frequency characteristic, executes photoelectric conversion and outputs the image pickup signal. A control value output means A outputs the control value based on the component in the image pickup signal and the space frequency characteristic of the optical low-pass filter 2 is controlled to the desired characteristic by the control value. When a high frequency component is inputted from the image pickup signal through a control value output means AH high-pass filter 7 and the control value is outputted based on the quantity of this high frequency component, the space frequency characteristic of the optical low-pass filter 2 is controlled to the desired characteristic by this control value. Thus, while suppressing the reduction of the contrast in the photographed picture, the image pickup signal is acquired not to include high frequency waves to be the cause of the moire stripes.

Title: Feeder circuit
Inventor: TAKADA SHINJI
IPC: H02J3/00
Filed: 1988-07-11
Abstract: PURPOSE:To prevent spread of the abnormality of a load by switching to a second system having commercial frequency upon trouble of a first system for feeding variable frequency power to the load and disabling switching upon occurrence of abnormality in the load. CONSTITUTION:Power is fed from a commercial power source 1 through switches 4, 5, a system abnormality detector 9 and a variable frequency power source 2 to a load 3. Currents detected through CT10a and CT10b arranged at the input and output sides of the variable frequency power source 2 are coupled differentially and fed to an overcurrent detector 11. When the difference between the detected currents exceeds over a predetermined level, a power source abnormality detector 12 judges that the variable frequency power source 2 is abnormal and opens the switches 4, 5 while closes a switch 6 thus feeding power from the commercial power source 1 to the load 3. When the level of current detected through a CT7 exceeds over the threshold of an overcurrent detector 8, the system abnormality detector 9 judges that the load 3 is abnormal and opens the switches 4, 5 while disables closure of the switch 6. By such arrangement, the abnormality of load 3 is prevented from spreading.

IPC: H01L21/52
Filed: 1991-07-15
Abstract: PURPOSE:To provide a semiconductor pellet having an index which can prevent an erroneous reading in the case of attaching pellets and rapidly read it. CONSTITUTION:An index 4 for designating a directivity is so formed on a surface of a semiconductor pellet 1 as to be recognized with bare eyes. The state of the index itself and the forming position of the index are so devised as to designate the directivity at the index. Accordingly, since the direction of the pellet can be easily confirmed, its operability is enhanced. Since the reading of the index can be simply performed, an erroneous reading is eliminated, and improper attaching of the pellet can be prevented. If an index confirming software is added to a semiconductor pellet attaching machine, the confirmation of the direction of the pellet can be automatically performed, and improper pellet attaching can be reduced to 0%.

Title: Multiplication type d/a converter
Inventor: AKAGIRI KENZO
IPC: H03G3/00
Filed: 1984-08-22
Abstract: PURPOSE:To attain D/A conversion of a nonlinear PCM signal and to prevent the generation of noises by using a switch controlled in relation to an input digital signal to control the time width and polarity of the current applied to an integration device. CONSTITUTION:A couple of variable current sources 29, 30 controlled by a common current control signal 33 and applying currents with different polarity but proportional amplitue to integration devices 21, 22 are provided, and switches 31, 32 controlled with an input digital signal are provided respectively between variable current sources 29, 30 and the integration devices 21, 22.

Title: Method for forming contact hole
Inventor: MIZUMURA AKIRA
IPC: H01L21/768
Filed: 1997-06-30
Abstract: PROBLEM TO BE SOLVED: To provide a method for forming a contact hole by which good quality properties regarding a contact part can be ensured and the process for manufacture can be simplified. SOLUTION: A photoresist film 18 is formed in advance at a position for forming a contact hole in a shape, matching the contact hole. An interlayer insulating film 14 is formed on the other region. The photoresist film 18 is removed to form a contact hole. Since the etching process of the interlayer insulating film 14 for forming the contact hole is not necessary, the process of manufacture becomes simple. Even when the contact hole extends over lower wrings 10a and 10b because of the deviation of the photoresist film 18 from the designed position or size, the part of the insulating layers (insulating layer 11a, sidewall insulating layer 12b and so on) covering the lower wiring 10a or so does not become thinner because of over-etching, since the contact hole itself is not etched for forming.  Accordingly, withstand voltage between the lower wirings 10a and 10b and the contact hole is not reduced.

Filed: 1984-08-22
Abstract: PURPOSE:To contrive simplification of total processes and improvement of yield by simultaneously forming an impurity region which has two or more conductivities on one main surface of a semiconductor substrate with one ion implantation process through a resist pattern. CONSTITUTION:One main surface of a semiconductor substrate A is covered with the first insulation film 1, a desired resist pattern 3 is formed thinner than usual, ions are implanted on all the surface and an impurity region 5 which has a different conductivity from a conventional impurity region 4 is formed directly under the resist pattern 3. The control of the conductivity of the impurity region 5 can also be made by increasing the thickness of the desired resist pattern 3' and the impurity region 5 is made a new impurity region 5'. If the first insulation film 1 is removed by a etching technique before the ion implantation process with the desired resist pattern 3 and then ions are implanted, a region which has equal conductivity to the impurity region 5 and a new impurity region 4' which has a different conductivity are formed. Thus, by controlling the thickness of a resist film for forming a desired pattern, a number of impurity regions which have a desired conductivity can be formed.
