Title: Method for measuring attachment and repellent activity of mytilus edulis galloprovincialis
Inventor: KITAJIMA FUMIO
IPC: A01K67/00
Filed: 1993-03-19
Abstract: PURPOSE:To readily measure the attachment and repellent activity of Mytilus edulis galloprovincialis under conditions close to the natural state in a laboratory by a specific method using a petri dish having holes for feeding seawater in the wall surface. CONSTITUTION:A test paper, coated with a test sample and having holes formed therein is initially fixed to a petri dish having holes for feeding seawater or its diluted liquid (seawater, etc.) in the wall surface with agar. The petri dish having the test paper fixed thereto is then placed in a water tank having an aerating means and seawater, etc., are then placed in the water tank so as to enable the feed of the seawater from the holes in the wall surface of the petri dish without sinking the whole petri dish in water. Thereby, the movement of Mytilus edulis galloprovincialis placed in the petri dish is observed. Furthermore, seawater at 80-100% concentration is usually used as the seawater, etc. The test on measurement of the attachment and repellent activity of the Mytilus edulis galloprovincialis is preferably carried out in the dark at 15-20 deg.C. After starting the test, the results can generally be judged within 10-24hr.

Title: Color picture forming device
Inventor: SUGISHIMA KIYOHISA
IPC: H04N1/46
Filed: 1990-03-12
Abstract: PURPOSE:To facilitate the color balance between different devices and between same devices by providing a correction means for comparing a reference color picture signal and a read color picture signal and correcting the color picture signal from the result. CONSTITUTION:A color patch print of a color copying machine A is placed on an original platen of the machine A to start the reading. The read picture information enters a memory 109 and is compared with picture information of a color patch of a machine B transferred to a RAM 115. Based on the difference between the density of prints, a gamma correction curve in a color correction circuit 108 is revised as shown in figure. That is, the gamma correction curve after the revision (dotted lines) is revised to have a smaller output data level when an input data level is smaller and to have a higher output data level when the input data level is higher than that of the gamma correction curve before the revision (solid lines). It is possible to match the color balance of the machine A with that of the machine B by revising the gamma correction curve in this way.

IPC: G11B5/187
Filed: 1980-05-09
Abstract: PURPOSE:To reduce the working time, by applying a turn or oscillation to a block formed by a number of head chips in a right-angled direction to a gap for a grindstone formed by arraying a prescribed oval surface in accordance with the pitch of a head chip. CONSTITUTION:An oval surface 6, which satisfies an equation (y-R)<2>+sin<2>theta. x<2>=R<2> and is decided by the curvature R of the tape travelling direction a-b and the gap azimuth theta, is formed on the surface of a grindstone 7 and in the same pitch as the pitch p of a head chip 1 provided to a block 4. Coincidence is obtained between the center of each head chip 1 and the center of the surface 6, and then a turn or oscillation is given to the block 4 with a curvature radius R and centering on e-f which is parallel to the gap. Thus grinding is given to the direction a-b to ensure an even curvature radius R. As a result, the working time can be reduced.

Title: Heat storage type refrigerator
Inventor: YAMADA KOJI
IPC: F25D17/06
Filed: 1988-03-15
Abstract: PURPOSE:To prevent a temperature rise immediately after the shifting from a heat accumulation mode operation to a normal cooling mode operation by first changing over the cooling medium passage from the evaporator side for heat accumulation to the main evaporator side, and then, after a certain time interval, starting the operation of a cold air circulation fan disposed near the main evaporator. CONSTITUTION:Upon shifting from a heat accumulation mode operation to a normal cooling mode operation, a fan 29 is started after a delay time of DELTAt. When solenoid valves 9, 15 are switched to the main evaporator side 13 under a condition where the heat accumulation is hardly taking place to the heat accumulation material 18 around the evaporator 19 for heat accumulation, the cooling medium at a higher temperature coming out of the outlet side 19b of the evaporator 19 flows into the inlet side 3a of the main evaporator 13 during the stage immediately after the switching. Since the fan 29 is not operated immediately after the switching, the air at a higher temperature is not circulated in the refrigerator. As the low temperature liquid cooling medium is supplied to the main evaporator 13 by a compressor 1 during the delay time DELTAt to delay the operation of the fan 29, the temperature of the main evaporator 13 will have been dropped by the time the fan 29 is started, and so, the temperature of air delivered by the start of the fan 29 is low.

Abstract: PROBLEM TO BE SOLVED: To prevent the crossing corners of the breaking-off grooves of a printed wiring board from damaging when performing the breaking-off of the board. SOLUTION: Connecting a main board 1a and an auxiliary board 2 by plural discrete thin connection portions constituting a breaking-off portion of a rectangle contour, breaking-off grooves 3a, 3b are provided in the breaking-off portion. In the crossing portion of the breaking-off grooves 3a, 3b, the breaking-off groove 3b present on the long side of the breaking-off portion is provided to extend it from the crossing portion to the outside. Since by this extension a bending force acts collectively on the thin connection portions of breaking-off grooves 3a present on the short side of the breaking-off portion, the breaking-off is performed easily.  Lengthening the breaking-off groove 3b present in the other crossing portion of the long side too, the bending force acts collectively on the thin connection portions to make possible the easy breaking-off of the auxiliary board 2 from the main board 1a. Also, since the load applied to the main board 1a by its bending work when performing the breaking-off is distributed to the extension portions of the breaking-off grooves 3b, the reliability of an electronic circuit integrated into the main board 1a can be improved.
