IPC: H04L12/851
Filed: 1993-10-04
Abstract: PURPOSE:To effectively utilize resources by reducing a delay by managing and controlling the resources in a transmission line, at the time of conducting packet switching between plural nodes. CONSTITUTION:When a control part 94 receives a resources request packet through a storage part 92 of a packet switching equipment 91, the control part 94 acquires resources by referring to a mapping table part 96, and thereafter, registers it in a resources information table part 95. Thereafter, when a packet with an ID is received, packet switching is conducted, based on the corresponding resources information of the control part 94. Also, when a packet without an ID is received the mapping table part 96 is referred to an when utilizable switch resources exist, switching is conducted. Moreover, when the packet is received, a monitoring part 97 monitors whether the packet received by the packet switching equipment 91 goes along information of the resources information table part 95 or not, and informs it to the control part 94.

Abstract: PURPOSE:To absorb an irregularity in capacity during a manufacturing process by a method wherein a structure where a dielectric film on a semiconductor substrate is sandwiched between electrode films and a P-N junction structure are connected in series to form a capacitor, and a reverse bias voltage for capacity control use is applied to the P-N junction. CONSTITUTION:A capacity formation part is formed of a structure where a first capacitor of a MIS(Metal Insulator Semiconductor) structure in which a nitride film 4 has been sandwiched between a P-type semiconductor region 3 and polysilicon 5 as electrode materials is connected in series with a second capacitor composed of a junction capacitor by a P-N junction structure of an N-well region 2 and the P-type semiconductor region 3. A composite capacity of a whole double structure of this semiconductor device, i.e., a capacity between the polysilicon 5 and the N-well region 2, is controlled by applying a voltage for capacity control use to an aluminum wiring part 6 and an aluminum wiring part 7 and by changing a junction capacity in such a way that a P-N junction between the N-well region 2 and the P-type semiconductor region 3 is reverse- biased. Thereby, it is possible to adjust a capacity value even after a manufacturing process.

Title: Focal point detection device
Inventor: NAKADA MASAHIRO
IPC: G03B13/36
Filed: 1998-09-03
Abstract: PROBLEM TO BE SOLVED: To improve accuracy of focal point detection by a simple circuit configuration. SOLUTION: A pixel signal outputted from a focal point detection sensor is A/D converted with an accuracy of 10 bits. A re-integration flag is 0 at the beginning. Therefore, the pixel signal is converted from 10 bits into 8 bits (step S316). The maximum value and the minimum value of the pixel signal are obtained (step S317) and the pixel signal is stored in a memory (step S321). Contrast is calculated together with calculation of defocusing (step S325). The re-integration flag is determined as 1 when the contrast is low, and the amount of the shift is obtained (steps S327, S329). Next, an integral action of the focal point detection sensor is performed again, to obtain the pixel signal.  After the pixel signal is A/D converted with an accuracy of 10 bits, it is converted into 9 bits (step S312), a shift amount is subtracted from it to be converted into a data length of 8 bits (step S313).
