Title: Solid-state image pickup device
Inventor: OZAKI TOSHIBUMI
IPC: H04N5/335
Filed: 1985-07-24
Abstract: PURPOSE:To extend a dynamic range, and to enhance an optical utilization factor by making the thickness of a gate oxide film for a buried CCD constituting a vertical CCD shift register thinner than that of a gate oxide film for a buried CCD organizing a horizontal CCD shift register. CONSTITUTION:The titled device has a region 4 in which a vertical CCD shift register is integrated, a region 5 in which a horizontal CCD shift register is integrated, a first conduction type semiconductor substrate 6 and a low concentration diffusion layer 7 for a buried channel, and the thickness of a gate oxide film for a buried channel CCD forming the vertical CCD shift register is set at a value thinner than the thickness of a gate oxide film for a buried channel CCD shaping the horizontal CCD shift register. Accordingly, the signal storage tolerance of the vertical CCD shift register giving the quantity of charges stored an upper limit can be expanded, thus extending a dynamic range to the amount of incident beams, then improving an optical utilization.

Title: Signal generating apparatus
Inventor: FUKAYA TAKESHI
IPC: G01B7/30
Filed: 1989-06-23
Abstract: PURPOSE:To prevent mutual interference of magnetic circuits thereby to reduce noises by arranging a pair of permanent magnets so that the sides of said permanent magnets confronting each other are of the same polarity. CONSTITUTION:A signal rotor 11 of a cam pulley 10 has a protrusion 11a. Similarly, a signal rotor 12 has a protrusion (not shown). Electromagnetic pickups 21, 22 have permanent magnets 25, 26, respectively, so that the magnetic flux leaks from the N pole through cores 23, 24 to the S pole. Because of the protrusions formed in the signal rotors 11, 12, the gap between the cores 23, 24 is changed subsequent to the rotation of the cam pulley 10. In consequence to this, the magnetic flux passing through the cores 23, 24 is changed. The change of the magnetic flux is detected by coils 27, 28 to obtain an electromagnetic pickup signal. Since the permanent magnets 25, 26 confront each other at the sides thereof having the same polarity, there is caused no interference between the magnetic fluxes formed in the permanent magnets, and accordingly reducing the noises.

Filed: 1991-07-03
Abstract: PURPOSE:To enable electric field intensity to be increased by specifying a channel length so that a linearity of drain current-gate voltage characteristics can be achieved at a high drain voltage. CONSTITUTION:A silicon substrate 11 of an N-type semiconductor device 10 contains impurities and a specific resistance is set to approximately 10-20OMEGAcm. Ion-implantation conditions at the channel portion are B+(40KeV, 7X10<11>cm<-2>) and further B+(120KeV, 5X10<11>cm<-2>). A channel length is set to 1.0mum and a channel width is set to 50mum. Ion-implantation conditions of a source diffusion layer 12 and a drain diffusion layer 13 are As+(100KeV, 5X10<15>cm<-2>). A depth of the source diffusion layer 12 and the drain diffusion layer 13 is 0.3mum. With this configuration, drain current changes linearly for gate voltage. Therefore, by setting the channel length to be equal to or less than approximately 1mum, electronic field intensity can be increased to a sufficiently high value. Then, S/N can be improved since the drain voltage can be increased.

Abstract: PROBLEM TO BE SOLVED: To enable accurate judgement of the end point of treatment of a specimen, by installing a second magnetic field-generating source in the vicinity of a natural lighting part of which source is difference from a magnetic field- generating source for forming an electron cycrotron ECR surface, and forming a second ECR surface different from the above ECR surface, in the vicinity of the natural lighting part. SOLUTION: A second magnetic field-generating source 14 is installed in the vicinity of a natural lighting part, and a second ECR surface 15 is formed in a treatment chamber in the vicinity of the natural lighting part. The plasma density is low in the vicinity of the wall of a discharge tube. Microwaves travel along the outside of the discharge tube or in the wall of the discharge tube or in the treatment chamber and enter the second ECR surface. On account of the plasma formed by the microwaves, the plasma density in the vicinity of the natural lighting part is increased. By the etching effect of the plasma, a film of reaction subproduct becomes hard to stick on the natural lighting part. Thereby accurate end point judgment of treatment of a specimen can be prevented form being disturbed.
