Filed: 1988-10-13
Abstract: PURPOSE:To make it possible to measure the amplitude and phase of each element in any position by integrating pickup antennas in a phased array antenna consisting of plural element antennas and phase shifters connected to respective element antennas. CONSTITUTION:The same antennas as element antennas are arranged as pickup antennas 9 in the phased array antenna consisting of plural element antennas and phase shifters connected to respective element antennas and connected with each other.

Abstract: PURPOSE:To relieve stress, and to obtain excellent characteristics and reliability by forming the surface in two layer structure of a plasma CVD-SiNx film and a CVD-SiO2 film and making total film thickness of said films satisfy the conditions of non- reflection to signal beams. CONSTITUTION:A buffer layer 7, an optical absorption layer 6 and a window layer 5 are formed onto a substrate 8 in succession, an SiO2 film 2 is attached onto the surface and a window is shaped, and a P type impurity is diffused to form a P<+> diffusion region 4. The SiO2 film is removed, an SiNx film 1 is shaped through a plasma CVD method, and an SiO2 film is laminated through a CVD method, thus obtaining protective films having double layer structure. Since films applying exact opposite stress are superposed in the surface protective films formed in this manner, tensile stress and compressive stress mutually deny, and stress applied to InP/InGaAs is made smaller than conventional devices by approximately one figure up to approximately 10<8>dyne/cm<2>. The titled device has an effect even in the aspect of preventing pin holes because of double layer structure, stress applied to a semiconductor is relieved largely, and the surface protective films having no pin hole are acquired, thus also improving reliability. The conditions of non-reflection are obtained at a wavelength of 1.55mum.

Title: Optical scanning device
Inventor: TAKADA TAMA
IPC: G02B13/00
Filed: 1992-09-28
Abstract: PURPOSE:To suppress image plane distortion in a subscanning direction and to obtain the optical scanning device which has high resolution and a wide field angle by equipping an image formation optical system with an ftheta lens and satisfying a prescribed condition. CONSTITUTION:The laser beam emitted by a semiconductor laser 1 is collimated by a collimator lens 2 into a parallel beam. The parallel beam is converged only in the subscanning direction through a cylindrical lens 3 which has power in the subscanning direction to form a thin and long line image which is parallel to a deflecting surface on a reflecting surface of a rotary polygon mirror 4. The reflected beam is deflected in scanning as the rotary polygon mirror 4 rotates to form image on a scanning line 7 by passing through the ftheta lens 5 and a cylindrical lens 6. In this case, the cylindrical lens 6 is also a lens having power only in the subscanning direction. Then e/f >0.60 is satisfied, where (f) is the focal length of the whole ftheta lens system and (e) is the distance between the deflection point and the image-side principal point of the whole ftheta lens system.

Title: Variable resistor
Inventor: OSHIMA KAZUHIRO
IPC: H01C1/12
Filed: 1995-10-05
Abstract: PROBLEM TO BE SOLVED: To provide a variable resistor whose resistance value can be changed stably and repeatedly within a specified range according to its operation. SOLUTION: The end part of a conductive layer 34a to be connected to the connecting part 33d of a resistance layer 33 of a variable resistor is formed in a manner to be θm in angle against the tangential line of the outer circumference side of the arcuate resistance layer 33 in such a way that a distance Lm between the sliding part of a sliding element as shown by a dotted line A and the end of the conductive layer 34a may be longer successively. The sliding element is turned to slide the sliding part from a position P11 of the end of a projected part 33a to a position 13 of the end of the connecting part 33d of the layer 33, so that the distance Lm becomes longer successively, resulting in increased resistance value between the sliding part and conductive layer 34a.  Even if the sliding part is close to the end of the layer 33 connected with the layer 34a, the resistance value can be changed according to the operation of the variable resistor.

Title: Sense amplifier
Inventor: YAMAZAKI TAKASHI
IPC: G11C11/34
Filed: 1984-12-05
Abstract: PURPOSE:To make a sense amplifier durable even to high-speed operations, by providing a means which drops the initial state of the output level of an integrated circuit to an intermediate level and another means which abruptly changes the output level by catching the level variation of input signals or signals synchronizing with the input signals by means of a latch circuit. CONSTITUTION:The input of an output inverter 10 is taken not from an RAM output line 4, but from the node 14 of a sense amplifier 14. When a timing signal 3 starts to become ''H'', an (n) channel transistor 18 starts to be turned on and the electric potential at nodes 14 and 15 once drops to an intermediate level toward ''L''. When the electric potential drops, (p) channel transistors 19 and 20 are instantaneously turned on, but ''L'' and ''H'' are immediately loaded onto RAM output lines 4 and 5, respectively. When the node 14 starts to drop to ''L'', the transistor 19 starts to be turned on and to pull up the electric potential at the node 15 to ''H''. As a result, the transistor 20 starts to be turned off and the electric potential of the node 14 is further dropped. Therefore, operations act multiplicationally and output data are determined faster than conventional ones.

Title: Solid image pickup device
Inventor: HORI MIKIKO
IPC: H04N5/341
Filed: 1998-09-11
Abstract: PROBLEM TO BE SOLVED: To enable the charge in a photodiode layer at low voltage to be read out even if a surface shield structure is adopted in a CMOS image sensor. SOLUTION: For example, a surface shield layer 17 is formed separate from the end of a read out gate 14 on the surface of a photodiode layer 16. Next, an impurity region 21 in higher concentration than that of the photodiode layer 16 is formed between this surface shield layer 17 and the read out gate 14. Through these procedures, the formation of potential barrier by the surface shield layer 17 is suppressed for facilitating reading of the charge accumulated in the photodiode layer 16, thereby enabling the read out voltage to be lowered.
