Abstract: PURPOSE:To improve containability of the cleaner, and also, to improve strength of a handle by forming a turning part of the cleaner main body and the handle part like a ring and using it as a grip at the time of bending the handle part. CONSTITUTION:Ring-like pivotally supporting parts 15, 16 are formed in the upper parts of the right case 2 and the left case 3, respectively.

Title: Color picture forming method
Inventor: NOMURA HIDEAKI
IPC: G03C7/407
Filed: 1997-08-11
Abstract: PROBLEM TO BE SOLVED: To improve overall picture quality by bettering both graininess and sharpness without damaging other picture quality factors, by conducting color development under the existence of competitive compounds. SOLUTION: A picture obtained by development under the existence of competitive compounds is processed. As competitive couplers among competitive compounds, there are a non-coloration coupler, which is harmless if it remains in a developed photographic material after a coupling reaction with an oxidant of a color developing agent, and a water-soluble pigment producing coupler, which is highly water-soluble and does not remain in a photographic material, and either of them can be used. Among competitive compounds, the competitive couplers are especially effective among which a competitive coupler, a compound expressed by an expression is effective. In the expression, R and R', which can be substituted for one or more of a second to sixth position of a benzene ring, denote alkyl radicals or the like the number of whose carbon atoms is 1 to 5.  A competitive developer is required to have a moderately weak developing action for controlling moderately a developing reaction of the color developing agent, and a preferable competitive developer is a hydroquinone derivative or its salt.

Title: Evaluation of semiconductor device
Inventor: YANAGA MASATAKA
IPC: H01L21/66
Filed: 1990-08-17
Abstract: PURPOSE:To enable package crack to be evaluated easily and without any individual difference by performing relaxation pressure cracker test after measuring weight of a semiconductor device and then measuring weight of the semiconductor device after the relaxation pressure cracker test is completed for obtaining a difference with the previous weight. CONSTITUTION:Weight of a sample semiconductor device is measured before test. Then, relaxation pressure cracker test of this semiconductor device is performed and then weight after the relaxation pressure cracker test is completed is measured. Then, presence or absence of crack of the semiconductor device is determined according to the difference in weight before and after the test. The relaxation pressure cracker test may cause dew to be formed at an outer periphery of the semiconductor device depending on the test. This dew-forming results when temperature of the semiconductor device or that of a test bath is reduced as compared with steam temperature. When there is a crack in the semiconductor device, dew-forming results even within the crack and weight is increased by the weight of water of dew-forming within the crack as compared with a case when there are no cracks, thus enabling presence or absence of package crack of the semiconductor device to be evaluated by measuring weight of the semiconductor device before and after the relaxation pressure crack test.

Abstract: PROBLEM TO BE SOLVED: To provide a limited multi-address cipher communication method suitable in the case of making a transmitter arbitrarily multi-address transmit chargeable data, making a receiver select required data from them and performing charging for the selected data. SOLUTION: For the purpose of making key delivery data multi-address transmitted by a broadcasting station side equipment 100 small, the secret information of the receiver is prepared corresponding to the partial set of a certain finite set.

Abstract: PURPOSE:To effectively perform a screw loosening work by detecting the meshing of a bit and screw by loosening a screw. CONSTITUTION:In case of a bit getting into contact with a screw and biting with the head thereof, the rotation of the bit is stopped. Meanwhile, the output of an encoder E1 is monitored by a computer CP and the current value, the number of rotations and rotating direction equivalent to the screw loosening torque for the motor M1 for screw tightening are commanded with the elimination of the output by the rotation stoppage of the bit as timing. Accordingly, current is fed through a 1st controller C1 and the bit is going to rotate in the direction loosening the screw. The output of the encoder E1 is then monitored by the computer CP in advance and at the time when specified rotations are obtained in the reverse direction to the previous time the screw is decided to be loosened and a command is rendered so as to stop the operation of the motor M1 for tightening screw and the cylinder CL1 for pressing the bit.

Abstract: PURPOSE:To increase frequency response, by a method wherein a current command is corrected in accordance with a deviation between an acceleration signal, obtained by differentiating a motor speed; and another accelerating signal, estimated from the current command by using a model standard. CONSTITUTION:A current command T (S) is obtained as the sum of a value, obtained by integrating a deviation signal between a speed command V (S) and a motor speed W (S) by an integration term, and another value, obtained by the feedback value of the motor speed W (S) through a proportional term,. On the other hand, and acceleration signal is obtained by differentiating the motor speed W (S) by a differentiating term. Another accelerating signal is estimated from a current command by employing the standard model of a speed control system. A deviation signal A (S) between the acceleration signal and the estimated acceleration signal is given to a motor adding it to the current command T (S). According to this method, the stability of the control system of the servomotor may be improved.
