Title: Field effect transistor
Inventor: MANNO TOSHIKAZU
IPC: H01L29/78
Filed: 1990-10-24
Abstract: PURPOSE:To lower a contact resistance between a back gate region and a source electrode to obtain a field effect transistor having excellent frequency characteristic by providing a groove in the back gate region and forming the source along the wall surface of the groove. CONSTITUTION:A groove 9 having the V-shaped cross-sectional view is formed in a back gate region 1 between a couple of source regions 3 and a source electrode 2 is formed extendingly on an interlayer insulating film 5 in the vicinity of a gate electrode 4 from the slanted surfaces of the groove 9. Thereby, a contact area between the source electrode 2 and back gate region 1 increases and a contact resistance thereof can also be reduced. Moreover, groove 9 is also formed deeper than the peak value of impurity concentration in the depth direction of the back gate region 1. Therefore, since the back base region 1 and source electrode 2 are connected in the area providing the highest concentration of impurity among the back gate region 1, the contact resistance of thereof can further be lowered.

Title: Electronic endoscope capable of digital output
Inventor: AMANO MINAMI
IPC: A61B1/04
Filed: 1998-10-08
Abstract: PROBLEM TO BE SOLVED: To suppress a data quantity that is otherwise decreasing in the endoscope conducting interpolation processing corresponding to high image quality processing. SOLUTION: In the endscope where an electronic scope 1 with a CCD 3 having a high pixel number such as 800,000 pixels having a color filter is provided with an interpolation circuit 10 that applies interpolation arithmetic operation to an image signal, and a processor connecting to the electronic scope 1 is provided with a digital output section to output a digital image signal externally, whether or not an operation of the interpolation circuit 10 is to be executed is switched. Thus, an image signal in an object to be observed with high image quality is outputted as a digital signal from the digital output section. When the interpolation circuit 10 is switched to a non-operation, digital image data not receiving interpolation processing are outputted to an external device such as a personal computer and a memory capacity of the external device is saved.

Title: Pressure reducing valve
Inventor: YUMOTO HIDEAKI
IPC: G05D16/16
Filed: 1987-11-12
Abstract: PURPOSE:To avoid the increase of the flowing speed of a liquid at a section between a 2nd valve seat part and a main valve body in case the distance between a 1st valve seat part and the main valve body is decreased by forming a stepped 2nd main valve body part in a body with the main valve body part at the upper part of this valve body after defining the plane part of the main valve body set at the inlet side as a 1st main valve body and then setting the 1st and 2nd valve seat parts in the places of the valve seat members opposite to both main valve bodies. CONSTITUTION:The plane part of a main valve body 118 of a flat plate type set at the inlet side of a valve port 114 of a pressure reducing valve is defined as the 1st main valve body part 1. Then the stepped 2nd main valve body part 2 is provided in a body with the part 1 at the upper part of the part 1. Then the 2nd and 1st valve seat parts 4 and 6 are formed in the places of valve seat members 3 and 5 opposite to both parts 1 and 2. The part 6 is energized toward the part 1 by means of a countersunk spring 7 serving as an elastic member so that the distance L between the parts 6 and 1 is reduced less than the distance H between the parts 4 and 2 by the degree of displacement of the spring 7. Thus it is possible to avoid such a case where the fluid is reduced with only the degree of displacement of the spring 7 kept as it is in case the distance L is decreased.

Filed: 1985-12-20
Abstract: PURPOSE:To easily detect a dropout based upon the disturbance of a waveform by controlling the change of the ratio of a side band wave signal component to the carrier signal component of a reproduced RF signal to emphasis the disturbance of the waveform. CONSTITUTION:A boosting circuit 15 in a video signal reproducing device changes the relative signal level of a side band wave signal component to a carrier signal component in the spectrum signal component of a reproduced RF signal SRF and outputs a comparing signal SBO increasing the disturbance of the waveform. The waveform of the signal SBO is compared with a dropout detecting reference signal VDO by a comparing means 16, a frequency converting signal SCOM to be changed when the waveform of the signal SBO crosses the signal VDO is sent from the means 16 and a dropout detecting signal SDET based upon the frequency change of the signal SCOM is sent from a frequency detecting circuit 18. When the dropout is generated and the disturbance of the reproduced RF signal is increased, the dropout based upon the disturbance can be easily detected.

Title: Optical transmission equipment
Inventor: NAKADA HIROAKI
IPC: H04B10/54
Filed: 1993-11-17
Abstract: PURPOSE:To provide an optical transmission equipment which can compensate the dispersion of a wavelength due to the difference of a transmission distance over a wide range and which is superior in economy by serially connecting plural DCF (the wavelength dispersion compensation fiber of a high dispersion fiber) to the optical transmission equipment of a CATV center. CONSTITUTION:A signal mode fiber (SMF) has the wavelength dispersion coefficient of about 17ps/km/nm in a wavelength 1.5mum band. The high dispersion fibers 41-43 have the negative wavelength dispersion coefficients of -70ps/nm. Light passing the high dispersion fiber 41 of -70ps/nm, i.e,. signal light transmitted from an output terminal 53 can be compensated with wavelength dispersion of SMF having a length of about 4km. The wavelength dispersion of about 8km from an output terminal 52 and that of about 12km an output terminal 51 can similarly be compensated. Thus, optimum signal light may be selected from among the output terminals 51-54 for the purpose of transmission to a place different in a transmission distance. The minimum high dispersion fibers can deal with any distance from a short distance to a remote distance for the fibers 41-43 of serial connection.

This discharge plasma sintering makes it possible to sinter at a low temp. by rapid heating. In this sintering, excess growth of the particles of the alumina powder does not occur, thereby a high density alumina ceramic is formed without adding other components such as zirconia.
