Title: Solid state image sensor element
Inventor: NAKAI MASAAKI
IPC: H04N5/335
Filed: 1984-05-02
Abstract: PURPOSE:To prevent the deterioration of the transfer efficiency of a horizontal charge transfer element without utilizing a narrow channel effect, by a structure wherein the channel regions of the connecting part of the vertical and horizontal charge transfer elements are controlled by two gate electrodes. CONSTITUTION:The channel regions for transferring charges from a vertical charge transfer element 2 to a horizontal charge transfer element 3 are formed by a region 51 under the first gate and a region 52 under the second gate. When the charges are transferred by the horizontal charge transfer element 3, part of the charges, which are transferred to a part under the first gate 53, flows into the region 51, too. When the charges are transferred to a part under the first gate of a next stage 54, the charges of the region 51 are attracted by an electric field formed by the region 52 under the second gate electrode. The charges flow out to the part under the first gate electrode through the region 52 at a high speed. The deterioration of the transfer efficiency due to the channel regions 51 and 52 can be prevented. Since a narrow channel effect is not required to use, a channel width Wv' of the vertical charge transfer element can be made large, and the amount of the charge that can be transferred is made large.

Abstract: PURPOSE:To prevent in advance generation of fault due to overrun or the like by regulating a head moving range by a photo sensor and regulating a head moving limit by a limit switch to move stably an optical head within a prescribed range on a disc. CONSTITUTION:A shutter 22 and a couple of pressing pieces 23A, 23B are fited to a side wall of a holding frame 10. A couple of photo sensors 24A, 24B and limit switches 25A, 25B are provided to a prescribed position of a mounting base 1 respectively corresponding to the shutter or the like. The recording/ reproducing operation is started at the innermost circumferential position of a disc 4 for an actuator 11 of an optical head 10 and ends at the outermost recording position of the disc 4. Thus the information recording region on the disc 4 is made constant and stable recording/reproduction is attained.

Title: Phase angle detection unit
Inventor: YOSHIHARA TAKAO
IPC: G01R25/00
Filed: 1978-07-19
Abstract: PURPOSE:To facilitate the measurement of the phase angle of a higher harmonic of transmission and distribution lines by using two kinds of band-pass filter which cause only the fundamental wave of an input distorted wave and the n-degree higher harmonic to pass through and a phase locked loop circuit which generates an n- degree higher harmonic synchronized with the fundamental wave. CONSTITUTION:When input terminal 1 is connected to one end oftransmission and distribution lines, the n-dgree higher harmonic of the output of bandpass filter (BPF) circuit 3 becomes the waveform shown in (B) in the figure. Then, the fundamental wave of transmission and distribution lines is applied to phase locked loop (PLL) circuit 4 through BPF circuit 2, and PLL circuit 4 receives feedback dependent upon 1/n frequency divider circuit 5 and is so operated that the phase difference between the feedback signal waveform and fundamental wave 8 may be held zero, so that the n-degree higher harmonic outputted from PLL circuit 4 always becomes output waveform 9 having a phase equal to the n-multiplied wave of fundamental wave 8. As a result, the phase difference of the n-degree higher harmonic of input signals can be measured on a basis of this signal.

If the linear thermal expansion coefficient of the insert 10 is smaller than those of both the frame 2 and the substrate 1, at the time of temperature rise and drop, the solder is compressed between the surfaces opposite to the above described. With this constitution, the sealing junction can be pressed tightly without breakage of the frame 2 and the substrate 1.

Filed: 1992-04-09
Abstract: PURPOSE:To manufacture an electron gun having a tip with a small radius of curvature and high density by controlling the shape and the density based on the heating conditions utilizing the spike phenomenon among different kinds of materials. CONSTITUTION:In the case that an A metal film 12 is formed on a semiconductor material, for example, a Si substrate 11 and the substrate 11 is heated at a set temperature for a set period to diffuse A in the Si, the metal is diffused in the semiconductor in a sharp state due to the spike phenomenon between different kinds of the materials. Then, a SiO2 film is formed on the back side of the substrate 11 and patterned to remove a part of the film and give a mask 13. Next, the substrate 11 is immersed in an etching solution to remove the part which is not covered with the SiO2 mask 13 and expose a part with a sharp shape of the A 12 and thus a sharp electron gun is obtained. In this way, electron guns with high density and having a tip with a small radius of curvature can be manufactured easily by controlling the shape and the density utilizing the spike phenomenon.
