Title: Coffee pack
Inventor: KIKUCHI KEIICHI
IPC: A47J31/06
Filed: 1990-11-23
Abstract: PURPOSE:To smoothly extract the coffee liquid, and also, to quickly draining the hot water in a pack by sucking/discharging hot water into/from the pack through a filter by increasing/reducing atmospheric pressure in the pack and extracting coffee contained in the pack. CONSTITUTION:A coffee pack is placed into a cup 12 while holding its entry 3 side of hot water downward, thereafter, hot water is poured into the cup 12, and while positioning the entry 3 in hot water, a pushing part 2 of a tank 1 is pushed strongly from the front and the rear of the tank 1 with a hand and air in the tank 1 is extruded through a filter 4. Thereafter, the shape of the tank 1 is restored by the elasticity of the tank 1 by loosening a hand and by an action at this time, hot water in the cup 12 is sucked into the tank 1 through the filter 4. Thereafter, by pushing more strongly the tank 1, hot water in the tank is poured into the cup 12 through the filter 4, and also, by loosening a hand, hot water is sucked into the tank 1. By repeating it, coffee is extracted and after the extraction, the same operation is repeated over the cup 12, and the draining hot water from the tank 1 is carried out. In such a manner, the extraction of coffee and the draining hot water can be performed smoothly.

Title: Picture processing method
Inventor: ANDO KAZUHISA
IPC: H04N1/40
Filed: 1991-11-08
Abstract: PURPOSE:To decode a digital picture with fidelity to an original picture by selecting the coefficient of a spatial filter to be a specific value and maximizing the absolute value of the coefficient of a center part. CONSTITUTION:When the spatial filter is used for a multi-gradation picture signal read by a linear image sensor 11 to implement a filtering processing, the coefficient of the spatial filter is selected to be symmetrical to the center line as to the main scanning direction of the image sensor 11 and asymmetrical vertically as to the subscanning direction of the image sensor 11 to maximize the absolute value of the coefficient in the center. That is, the spatial filter symmetrical to the center line is used in the main scanning direction and the spatial filter asymmetrical vertically is used in a subscanning direction. Thus, edge-emphasis adapted to the difference from the resolution characteristic is implemented in the main scanning direction and the subscanning direction due to after-image or the like to obtain a digital picture with fidelity in the picture density of an original picture.

Title: Still tracking device
Inventor: ISHIBASHI HIROMICHI
IPC: G11B7/085
Filed: 1992-11-30
Abstract: PURPOSE:To continuously scan the information of an adjacent track having a half track pitch interval and to perform continuous still operation by arranging tracking marks whose polarities are different from each other in zigzag on an optical disk medium. CONSTITUTION:The polarities for detecting tracking errors of wobbling mark pairs 10a, 10b and 10c, 10d are opposed to each other and the pairs are alternately arranged. The total number of the mark pairs is odd number per track. When a laser beam scans the mark pairs 10a, 10b on a track A, a tracking error detection circuit 2 detects a tracking error signal. Then, when the mark pairs 10c, 10d are scanned, a tracking error signal whose polarity is opposed to the former is detected. However, since a FF 3 and a polarity inversion circuit 4 alternately inverse the polarity with the detection timing of the mark pairs, consequently, a tracking error signal having the same polarity is generated. The error signal is fedback to a tracking actuator of an optical head 11 through a control circuit 9 and the control in following up a track is executed.

Title: Ofdm-cdma system communication equipment
Inventor: SUDO HIROAKI
IPC: H04J13/16
Filed: 1999-11-11
Abstract: PROBLEM TO BE SOLVED: To prevent the error rate characteristic of a demodulation signal from deteriorating without lowering transmission efficiency. SOLUTION: An adding part multiplexes a signal 1 to a signal n diffused by each diffusing part and a 1st known signal. An IFFT part performs frequency division multiplexing frequency by allocating a multiple signal converted into a signal of a plurality of series by an S/P converter to a subcarrier 1 to a subcarrier k and allocating a 2nd known signal to a pilot carrier. A residual phase error detecting part detects a residual phase error from the 2nd known signal transmitted by the pilot carrier. The residual phase error detecting part detects a residual phase error from the 1st known signal transmitted by each subcarrier. An averaging part equalizes the residual phase error detected by each residual phase error detecting part. Each phase compensating part applies phase compensation processing to a demodulation signal by using the averaged residual phase error.
