IPC: H01Q3/26
Filed: 1989-04-11
Abstract: PURPOSE:To attain low power consumption and miniaturization and light weight by simplifying the constitution of a reception signal converter by employing a system by which an output signal from the reception signal converter is transmitted in analog fashion as an intermediate frequency signal is. CONSTITUTION:Signals in which a transmission signal and a local oscillation signal become time division signals inputted from an external device to an input terminal 12 are inputted to respective reception signal converter 4 by a distributor 5. The transmission signal outputted from the reception signal converter 4-1 is inputted to a feed circuit 3-1, and the transmission signal is divided, then, divided signals are inputted to plural small transmitter/receivers 2-1a to 2-1m connected to the feed circuit 3-1. The transmission phase of the transmission signal is controlled by a phase shifter 13, and the signal is amplified by an amplifier 15, and after that, it is radiated to a space via element antennas 1-1a to 1-1m. Thus, the circuit configuration of the reception signal converter 4 can be simplified, and the transmission system of the reception signal converter 4 with a signal processor or the external device can be improved. In such a way, it is possible to attain the miniaturization, the light weight, and the low power consumption as a whole.

Title: Manipulated variable detecting system
Inventor: NISHIMURA KUNIO
IPC: F02D45/00
Filed: 1998-04-03
Abstract: PROBLEM TO BE SOLVED: To prevent an improper learning value from being maintained by detecting erroneous learning unrenewable by learning when compensating for an installation error in an accelerator opening sensor of an automobile by learning. SOLUTION: A judgment can be made that an idle position learning value egpdl is erroneously learnt by capturing a situation where accelerator opening epdl hardly moves over a long period ('YES' in S220, S240) still in an idle OFF state ('YES' in S230). The idle position learning value egpdl obtained by idle ON position learning processing can be set to a proper initial value by this judgment (S250). Hereafter, learning processing can be started in idle ON position learning control, and since a proper idle position learning value egpdl can be obtained, accelerator opening can be accurately detected, so that drivability can be excellently maintained.

IPC: H01L21/76
Filed: 1994-04-28
Abstract: PURPOSE:To flatten an integrated circuit even when the polishing rate and the film thickness are changed by a method wherein a polishing stop film, a buried film and a low-polishing-rate film which are specific are deposited sequentially on the entire surface of a substrate and they are polished and removed until the polishing stop film in a recessed part is exposed. CONSTITUTION:A polishing stop film 2, a buried film 3 and a low-polishing-rate film 4 are deposited sequentially on the entire surface of a substrate 1 having recessed parts and protruding parts. In this case, the buried film 3 is formed in a film thickness in which the surface position of the buried film 3 in the recessed parts becomes lower than the surface position of the polishing stop film 2 in the protruding parts, and the low-polishing-rate film 4 is deposited up to a film thickness in which the surface position of the polishing stop film 2 in the protruding parts becomes a height nearly equal to the surface position of the low- polishing-rate film 4 in the recessed part. In addition, as the polishing stop film 2, a film whose polishing rate is low as compared with that of the buried film 3 is selected, or a film whose polishing factor is different as compared with that of the buried film 3 so that the buried film 3 is removed after a later polishing operation and that a polishing operation is stopped when the polishing stop film 2 is exposed. Then, the protruding parts in the low- polishing-rate film and the buried film are polished and removed until the polishing stop film is exposed.

Title: Grinding device and element
Inventor: ANDO NORIO
IPC: H01L21/304
Filed: 1986-04-23
Abstract: PURPOSE:To enable accurate and sure grinding in a short time by furnishing a grinding wheel for wafers with a coarse grinding part, a medium grinding part and a finish grinding part, and thereby performing coarse, medium and finish grindings by a single grinding action continuously. CONSTITUTION:As a coarse grinding part 9 of a grinding wheel 6 has a grinding surface consisting of an inclined surface with angle, the amount of grinding is set large and it becomes overlapped grinding. Because the finish grinding part 7 has a grinding surface with the least angle of inclination, the amount of grinding is less, but the ground surface is fine to yield a mirror surface. As the undersurface of this finish grinding part 7 is flat, the ground surface of wafer 1 becomes a surface without micro-cracks. The medium grinding part 8 provides a greater amount of grinding than the finish grinding part 7 but less than the coarse grinding part 9, and performs medium grinding. By the use of this type of grinding wheel 6, wafer 1 is coarse, medium and finish ground by a single grinding action.

IPC: H04L1/06
Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To attain miniaturization and low power consumption while reducing the effect of fading. SOLUTION: Either of two systems of demodulation means 10a, 10b is used for a reference demodulation means, and when a reception electric field strength level RSSI reaches a zero level for a prescribed time due to abnormality in the demodulation means, a zero level detection section LZF 38 outputs a detection signal to switch a switch section SW 40 so as to switch signals Ib, Qb from a phase correction section 28a received by a zero cross detection section PRZ 42 into those from a phase correction section 28b, a time difference between the real sample point of an A/D converter section 18a and an ideal sample point is calculated on the basis of the detection signal from the PRZ 42, the calculated signal is given to DTFs 24ai, 24aq, 24bi, 24bq as a tap coefficient selection signal so as to correct sampling timing, thus the effect of fading can be reduced.  Since a sampling frequency Fsp of A/D converter sections 18a, 18b is set to a multiple of 4/m of the frequency Fif of an IF signal ((m) is an odd number being 5 or over), a conventional DSP 50 is enough for the purpose.

Title: Blade cleaning device
Inventor: NISHIKAWA MASAHARU
IPC: G03G21/00
Filed: 1983-05-27
Abstract: PURPOSE:To attain high cleaning capacity while preventing the bending deformation of a blade and the damage of an electric charge holding member by using a plane plate-shaped blade where a hollow part is formed near the tip part and pressing this blade at a specific angle. CONSTITUTION:Since a hollow part 9 is formed in a blade 6, the blade 6 is easy to deform in the direction where the hollow part 9 is crushed, and not only an edge part 10 but also the whole of a blade tip part 7 is bent toward a blade holder. If the blade 6 is pressed to an electric charge holding member 1 at an angle beta<90 deg. when the angle, which is formed between a tangent Z to the lower side face in the edge part 10 and a tangent X when the blade tip part 7 is bent, is denoted as alpha1, the angle alpha1 approximates 90 deg.. Since the blade tip part 7 is easy to bend because of the existence of the hollow part 9, the stiffness of the whole of the blade is enhanced, and the angle alphaa is a large value, and thus, a good cleaning effect is attained.
