Title: Method for detecting image signal
Inventor: HOFER GREGORY
IPC: H04N5/3728
Filed: 1999-10-12
Abstract: PROBLEM TO BE SOLVED: To reduce time needed to photograph an image with an electronic single frame camera, a digital camera, etc., by transforming camera electronics and selectively reading a subarea for an image sensor to be used to decide an image acquisition parameter, such as focussing and an exposure level. SOLUTION: The detection area 105 of an image sensor 100 is conceptually divided into a 1st row area 132, a 2nd row area 134 and a 3rd row area 136 in a vertical direction. It is also conceptually divided into 1st, 2nd and 3rd column areas 142, 144 and 146 in a horizontal direction. Ideally, only an image signal 115 from a detection subarea 150 is used for focusing and exposure arrangement. The detection subarea 150 consists of detection elements existing in the 2nd row area 134 and the 2nd column area 144. Thus, it is possible to reduce time needed to perform automatic focussing and exposure level decision.

Title: Indomethacin-containing agent composition for external use
Inventor: KIMURA NORITOSHI
IPC: A61P29/00
Filed: 1996-10-31
Abstract: PROBLEM TO BE SOLVED: To obtain a composition for a preparation for an external use capable of reducing irritation of indomethacin by including the indomethacin and guaiazulene. SOLUTION: This composition includes 0.2-2 pts.wt. indomethacin and 0.005-0.5 pts.wt. guaizulene based on 1 pts.wt. indomethacin. If necessary, other lower alcohols, antioxidants, dissolving assistants, emulsion stabilizers, surfactants, flavors, dyes, etc., are also formulated therewith. The indomethacin has strong antiinflammatory activities but irritates the skin as a side effect in the case of local administration compared with the case of the administration acting on the whole body such as oral administration. The formulation of the guaiazulene in combination with the indomethacin can reduce the irritation even in a high level of transdermal absorption.

IPC: H01L21/027
Filed: 1993-11-19
Abstract: PURPOSE:To improve line width stability of a resist pattern by enhancing controllability of a temperature and a processing time in a resist coating/ developing apparatus. CONSTITUTION:A wafer is conveyed between a cooling/temperature regulating unit (C) 5 for cooling or temperature-regulating a board, and a heating unit (HP) 8 for conducting hydrophobizing, prebaking, PEG (post exposure baking), postbaking, etc., by using a special purposed conveying system 6 independent from a main conveying system 2 of an apparatus. Thus, even when the wafer is conveyed between steps or units in which processing temperatures are largely different, unnecessary heat conduction via a conveying arm can be prevented, and a thickness of a resist coating film, a developing speed can be made uniform. The processing time in the units coupled by the special purpose conveying system can be controlled without depending upon an occupied state of the main conveying system. An accurate pattern formation with chemically amplifying resist which is easily affected by a wafer environment can be performed.

Title: Distance relay
Inventor: SAITO HIROSHI
IPC: H02H3/40
Filed: 1997-10-23
Abstract: PROBLEM TO BE SOLVED: To provide a distance relay which is capable of operating at a high speed when an accident happens by inhibiting the operation of the relay having a possibility of causing a malfunction by an exciting inrush current, by comparing the summed value of the absolute value of the differences between resistance components and inductance components obtained from a formula for finding the absolute values from an impedance range finding value with a constant. SOLUTION: An impedance change is discriminated from a summed value of R and L components. First and second calculating means 11 and 12 respectively find |ΔR|=|Rm-Rn| and |ΔL|=|Lm-Ln| as the absolute values of the variation of the R and L values found at different times (m) and (n). The transition of the variation of the summed value |ΔZ|=|>=R|+|ΔL| with time is found continuously, and |ΔZ| always varies at a level higher than certain sensitivity with positive values. The discriminated result of whether or not the operating amount |ΔZ| in one period is higher than a prescribed value does not become intermittent operations but is stabilized by continuous operations.  The value of a T1 timer can be realized with a time cooperative timer, which is shortened from the normal time by setting an appropriate value from the fastest operating time of a relay and the maximum time of the transient response period of the relay when an accident happens.

Title: Substrate for optical memory element
Inventor: BAN KAZUO
IPC: G11B7/24079
Filed: 1987-11-18
Abstract: PURPOSE:To obtain a good-quality reproduction signal of a large amplitude from pits by forming no guide grooves on both sides of the pits or forming the guide grooves narrower than the guide grooves at the points where there are no pits to said sides. CONSTITUTION:The guide grooves 11... are formed in pit format parts. Track number information and sector address information, etc., are formed in the form of pits 13... in the parts sandwiched by the adjacent guide grooves 11, 11, i.e., the parts 12 which function as guide tracks. Then, the influence by the guide grooves 11... is considerably decreased and, therefore, the diffraction of the light beam irradiated on the respective pits 13 is more efficiently induced than with the conventional type having the guide grooves on both sides of the pits as well. As a result, the good-quality reproduction signal of the large amplitude is obtd. In another embodiment, the narrow groove parts 11a, 11a are respectively formed to both side parts of the pits 13 in the guide grooves 11, 11. Although the amplitude of the reproduction signal from the pits is slightly reduced in this case, the amplitude of the reproduction signal from the pits is sufficiently increased and the possibility that the spot of the light beam deviates from the prescribed guide tracks 12 is eliminated.

Filed: 1990-10-29
Abstract: PURPOSE:To present the stock to form a tube body or a gutter like on the site by making the coil of metallic strip given the residual stress with the treatment of bending and bending back uniformly to the lateral direction. CONSTITUTION:The residual stress is given uniformly to the lateral direction by treating the predeforming part 30 with bending and bending back after uncoiling the metallic strip 10 from the uncoiler 20. On coiling, if the tension applying to the metallic strip 11 is the usual 2-3kgf/mm<2> grade, it is not operated to the direction to eliminate the applied residual stress. So, if the coil is coiled tightly as same as the usual coil, the applied residual stress is kept. On the time to form this metallic strip to the tube like or the gutter shape, it is made to curl to the lateral direction by utilizing the residual stress, so the products after forming is to have the same curvature rate. On the case that the tube is manufactured, the tube with excellent roundness is obtained.

Abstract: PURPOSE:To suppress heat loss of a semiconductor switching element, to realize miniaturization and to suppress electromagnetic noise at the start by a constitution wherein a voltage modifying means modifies the supply voltage to a driving circuit such that the semiconductor switching element does not enter into an activated region at the start of a motor. CONSTITUTION:At the start of a brushless motor 1, a microcomputor 18 detects collector-emitter voltages of power transistors 12, 13, 14 at the input ports I3, I4, I5 thereof. When thus detected voltages exceed an upper limit, for example, output of a base signal from an output port Q7 is interrupted and a transistor 25 in a voltage modifying circuit 24 is turned OFF thus connecting a resistor 27 between the positive terminal of a DC power supply 17 and the DC input terminal 15P of a driving circuit 8. DC supply voltage to the driving circuit 8 is lowered by an amount being born by the resistor 27 and starting current of a brushless motor 1 is suppressed thus lowering the collector-emitter voltages of the power transistors 12-14.
