Title: Optical system and optical module
Inventor: TSUCHIDA HIROBUMI
IPC: H04N5/225
Filed: 1998-03-17
Abstract: PROBLEM TO BE SOLVED: To constitute an optical system of one lens, to obtain a wide viewing angle >=80 deg., and to realize sufficient optical performance as a camera for monitoring by constituting the optical system of a bivonvex lens and a plane glass in order from an object side and providing a brightness diaphragm on the 1st surface of the lens or in the lens. SOLUTION: This optical system is constituted of the biconvex lens L and the plane glass base plate P in order from the object side, both surfaces of the lens L are spherical and the diaphragm S is arranged on the surface of the lens L on the object side. An image by the optical system is formed on the surface of the plate P on an opposite side to the lens L. Since the plane glass is frequently arranged on the image side of the lens system such as various kinds of filters or a protection glasses, etc., in a lens system for a video, aberration is compensated by the lens and the plane glass.  Namely since the lens system whose viewing angle is >=80 deg. is formed of one lens L, the aberration is compensated by the compensation effect of axial spherical aberration due to bending of the lens surface and the thickness of the plane glass in addition to a reduction effect that the focal distance of the entire system is shortened.

Abstract: PURPOSE:To enable a high frequency induction quenching coil without roughening of non-quenching face by constituting the coil in such a manner that currents flow in the opposite directions to each other in the respective connecting conductors which are brought into close contact with the faces to be quenched on two works. CONSTITUTION:First - fourth conductors 11-14 arranged as facing to the quenching faces in the two works, which are brought into close contact, are connected with first - fourth connecting conductors 21-24 respectively. A first current supplying body 111 is connected with one end of the first conductor and a second current supplying body 241 is connected with one end of the fourth connecting conductor 24. In the high frequency induction quenching coil having this constitution, the contact faces of two works are faced to space between the first connecting conductor 21 and the third connecting conductor 23, and the current is conducted in the coil.

Title: Read-only semiconductor memory device
Inventor: MATSUO RIYUUICHI
IPC: H01L29/78
Filed: 1984-04-25
Abstract: PURPOSE:To reduce the area of a chip, and to shorten a delivery time after acceptance of an order by forming floating gates just under a control gate and determining the connection of both gates through patterning by a mask. CONSTITUTION:In a first control gate CG3a section in a memory transistor Tr section, the thickness of a gate oxide film is the sum of thickness of a first floating gate FG13a and the thickness of Si oxide films on both sides of the first floating gate. In a second CG3b section, on the other hand, the thickness of a gate oxide film is only the thickness of an Si oxide film under a second FG13b because the CG3b and the second FG13b are connected electrically by a connecting conductor 14. That is, the threshold voltage of a first memory Tr in the CG3a section extends over approximately 1.5V and the threshold voltage of a second Tr in the CG3b section over approximately 0.5V. Consequently, a ROM having arbitrary bit informations is obtained by changing over a mask forming the conductor 14. Accordingly, the area of a chip per bit is reduced while shortening a delivery time after acceptance of an order.

Title: Method for detecting defect in semiconductor substrate and manufacture of sample as well as observation method for detect
Inventor: YANASE YOSHIO
IPC: H01L21/66
Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To obtain a detecting method in which whether a point exists on the surface of a semiconductor substrate or near its inside can be grasped precisely by a method wherein the point in which a laser-beam scattering body exists on the surface of the substrate or near its inside is detected and whether the point exists on the surface of the substrate or at its inside is detected. SOLUTION: In a first process, a laser-beam-scattering foreignbody-position detecting device is used, and the point of a particle which is stuck to the surface of a semiconductor substrate or the point of a foreign body (including a foreign body) existing near the surface down to the creeping depth of a laser beam from the surface is detected. Then, a laser-beam scattering microscope is used, and the actual existence of a laser-beam-scattering body is confirmed. In succession, in a second process, the shape of the point which is detected in the first process and in which the foreign body exists is observed by using a scanning probe microscope. At this time, the particle which is stuck to the surface of the substrate is viewed as a protruding shape, and a crystal defect is viewed as a recessed shape.  In addition, in the case of a defect which does not have any uneven shape, the defect is judged to be existing near its its inside. By combining the first process with the second process, the particle which exists on the surface of the substrate, the crystal defect or the defect which exists near the inside can be detected precisely.

Title: Transistor switch circuit
Inventor: FUKUI HIROSHI
IPC: H03K17/66
Filed: 1982-05-21
Abstract: PURPOSE:To suppress the displacement potential of a transistor and to reduce the loss of a snubber circuit, by using the 1st snubber circuit connected in parallel to the transistor and the 2nd snubber circuit connected in parallel to a diode to constitute an arm. CONSTITUTION:When an arm 2 is turned on, an arm 1 is held at power supply voltage E. At the same time, a snubber capacitor C11 of a TR1 is also charged up to the voltage E. The capacitor C11 is discharged with a capacitor C12 charged respectively when the arm 2 is turned off and an adversely parallel diode D12 of the arm 1 conducts. The voltage of the C11 is not reduced down to zero and can be freely changed by the ratio between C11 and C12. Therefore, the sudden forward voltage is applied to the TR1 when the D12 is turned off. However no displacement current is produced since said sudden forward voltage is restricted within a high voltage region. This process can reduce the capacity of the C11 and therefore reduces greatly the loss of a snubber circuit.

Abstract: PURPOSE:To enable the highly accurate measurement of a dimension by widening a measuring diameter range in matching relation to the thickness of an article to be measured, by moving a substrate having a mirror reflecting polarized scanning beam arranged thereto along a polarized beam. CONSTITUTION:The beam from a laser 13 passes through a tuning fork-shaped deflector 16 and a lens 17 to be scanned along an optical axis as deflected parallel vibration spots. The lens 17 has the reflecting position of the deflector 16 as a focus and the scanning beam passing through the lens 17 is split by a half mirror 18 and a mirror 19 while the split beams respectively reach fixed mirrors M1, M2. The beam reflected by the mirror M1 is converged onto the diameter axis S of an article B to be measured and the beam reflected by the mirror M2 scans only the vicinity of the edge of the article B to be measured. As this time, the mirrors 18, M1 and mirrors 19, M2 are made parallel. When the substrate 5 provided with the mirrors 18, 19 is moved along the optical axis as shown by an arrow a, the converging position of the beam laterally shifts along the axis S but is always present on the axis S. As mentioned above, even if a beam center-to-center distance is changed, the dimension of the article B to be measured can be measured with high accuracy.
