Title: Automatic focus device for video camera
Inventor: KAWAGUCHI NAOKI
IPC: G02B7/09
Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To reduce the power consumption. SOLUTION: The evaluation value corresponding to the high-frequency component of the intensity signal caused by a slight shift of a focus lens in one direction and another direction is received, and the shift quantity (focus shift quantity) of the focus lens for focusing is calculated (ST1-ST4). The focus shift quantity of the present field is stored in a buffer in the non-wobbling field except during a zooming action, during low-speed shuttering, and when the focus position is not located near a focal position (ST5-ST7), and the focus shift quantity is set to 0. The sum of the shift quantity of the focus lens on wobbling (wobbling quantity), the present focus shift quantity, and the focus shift quantity of the previous field stored in the buffer is used as the focus lens shift quantity to control the shift of the focus lens in the wobbling field (ST9-ST14). The moving time of the focus lens is shortened, and power consumption is suppressed.

Title: Cellulose fiber imparted with shrink resistance and its production
Inventor: FUJITANI TSURATAKE
IPC: D06M101/02
Filed: 1992-03-04
Abstract: PURPOSE:To obtain the subject fiber imparted with excellent and durable shrink resistance by heat-treating cellulose fiber and a specific ester component having plural carboxyl groups, thereby bonding the ester to the fiber through ester bond. CONSTITUTION:A polycarboxylic acid (preferably butanetetracarboxylic acid) is esterified with an aliphatic or alicyclic polyol, e.g. ethylene glycol, preferably polyethylene glycol having a molecular weight of about 200-2,000 to obtain an ester having >=2 carboxyl groups. The ester is impregnated in cellulose fibers and heat-treated to form an ester bond between the carboxyl group of the ester and the hydroxyl group of the cellulose fiber. The ester is bonded to the cellulose fiber through ester bond by this process to obtain a cellulose fiber free from formalin-generation and imparted with excellent and durable shrink resistance.

Title: Attaching structure for key cylinder for vehicle
Inventor: KOKURYO YOSHIKI
IPC: E05B77/44
Filed: 1993-03-08
Abstract: PURPOSE:To prevent water from adhering to a key cylinder, and to secure stealing preventing ability without increasing the number of part items. CONSTITUTION:Since in a state where a key cylinder 3 is fixed by a clip 14, the upper side of the key cylinder 3 is covered by a eaves 14h formed on the clip 14, water intruding into the inside of a door at the time of a rainfall or car washing is interrupted by the eaves 14h and therefore does not adhere to the key cylinder 3 not to give harmful influence. In addition, if the lower eaves 14h is formed on the lower edge of the clip 14, when the key cylinder 3 is actuated by incorrect unlocking input, the lower eaves 14h abuts on a door guard bar 15 to check the actuation of the key cylinder 3. Thus careless unlocking can be prevented without increasing the number of part items.

Abstract: PURPOSE:To achieve high-sensitivity and wide-band reproduction by providing a main and an auxiliary magnetic pole each consisting of a thin magnetic film having high magnetic permeability with windings for magnetic variation detection, and decreasing the film thickness of the main magnetic pole toward the tip surfce. CONSTITUTION:A main magnetic pole 11 has double-stage structure wherein the film thickness (t) of a part at a distance (a) from its tip surface is less than the film thickness T of a more inner part. Then, spacing between a medium and the main magnetic pole is denoted as (d), and d/T=0.25, t/T=0.5, and a/T=0.5. In this case reprodcuction characteristics are as shown by a graph 5 in the figure. In the figure, graphs 6 and 7 show recording density characteristics by a conventional main magnetic pole which has not the step structure atop and has film thicknesses T and (t). Consequently, the reproduction characteristics by the main magnetic pole having the step structure atop have high sensitivity corresponding to its overall thickness on a low-recording density side, and high density corresponding to its tip thin thickness on a high-recording-density side.

IPC: G10H7/00
Filed: 1994-03-17
Abstract: PURPOSE:To prevent an increase in memory capacity and processing capacity by storing the waveform PCM data on a pressure difference between the air flow to be blown and the reflected waves from an air column resonator and the flow rate of the air flow to be blown, reading out the data and applying the data to an acoustic section. CONSTITUTION:The characteristic PCM data on the pressure difference between the air flow to be blown in the reed of a wind instrument and the reflected waves from the air column resonator and the flow rate of the air flow to be blown are previously stored in the memory 1 in the circuit for synthesizing the vibration sounds of this reed by reading out the waveform PCM data stored in the memory 1 and applying the data to the acoustic part 2. The reed vibration sounds of the timbres corresponding to strong blow or weak blow are applied to the acoustic part 2 by changing the range of the pressure difference where the data are read out. The waveform data independent of the various intensity of the blow are stored in such a manner and the vibration sounds of the reed at the time of the strong blow and the weak blow are synthesized by one piece of the waveform PCM data, by which the increase in the memory capacity and the increase in the processing quantity are prevented.
