Title: Electronically-controlled perfuming apparatus
Inventor: WADA YUJI
IPC: A61L9/12
Filed: 1990-05-18
Abstract: PURPOSE:To enable the maintaining of flagrance almost constantly by compensating for a perfuming capacity of a scent agent dwindling with passage of time by a rise in the number of revolutions of a motor utilizing a secular drop in a battery voltage. CONSTITUTION:An oscillation circuit 2 and a drive circuit 3 are activated with a battery 1 to rotate a motor 4 and a fan 5 mounted on the motor 4 blows air to a scent agent 6 to disperse flagrance forcibly. As a voltage of the battery 1 lowers with passage of time, a charging time of a capacitor C1 is prolonged until it reaches a detection level of an integrated circuit IC 1 to cause a change in duty ratio in a direction of raising the number of revolutions of the motor 4. This enables the keeping a perfuming capacity of the scent agent 6 while allowing efficient utilization of the battery 1.

Title: Tape recorder
Inventor: IWAKI TOORU
IPC: G11B15/675
Filed: 1981-08-19
Abstract: PURPOSE:To allow the loading of a cassette when a mechanism structure is completely drawn out and at the same time to prevent the pushing operation of a recording button, by providing a misrecord preventing lever which works in response to an action to draw the mechanism structure out of the main body of  a device. CONSTITUTION:When a mechanism structure is drawn out, an interruption bar 50c of a misrecord preventing lever 50 is set opposite the right stepped part R of the 1st control hole 53b of a record lever 53. While the bar 50c is opposite to the left stepped part L when the mechanism structure is pushed into a device and the absence of a miserasion preventing pawl is detected for a cassette. The bar 50c is set opposite to a guide hold M between the stage parts L and R when the presence of the miserasion preventing pawl is detected. Therefore the lever 53 is prevented from being pushed by a record button when the mechanism  structure is completely drawn out. In case the lever 53 is kept pushed further,  the mechanism structure is pushed into the device main body while the pushing  of the lever 53 is prevented by the misrecord preventing lever 50.

Title: Etching
Inventor: TOOMASU ABURAHAMU
IPC: H01L21/3213
Filed: 1988-05-27
Abstract: PURPOSE: To form a tapered side of a conductive material by expanding the cut-off surface of the side section of a resist by performing etching for which a chlorine gas mixture is supplied at a prefixed flow rate with a low pressure and another etching for which the gas mixture of the same composition is supplied at a lower flow rate with the same pressure. CONSTITUTION: An photoresist pattern 10 is provided on an aluminum layer 12 formed on an SiO1 , layer 14 coating an Si substrate 16. Then the photoresist is sphered by partially melting the photoresist by heating the wafer to an appropriate temperature on, for example, a hot plate. Then the wafer is transferred to a plasma etcher and the aluminum is etched by using BCl3 , Cl2 , and CF4 until the aluminum is completely removed from the photoresist area under the same condition as that used in the preceding etching process while the flow rate of the Cl2 , gas is reduced to 3sccm from 12sccm. During this etching process, the cut-off surface of the photoresist is expanded in the lateral direction while aluminum side walls 18 are tapered.

Title: Signal ciphering system
Inventor: OOTA MINAKO
IPC: H04K1/02
Filed: 1994-06-13
Abstract: PURPOSE:To perform signal ciphering undecipherable for a third person without damaging original signals by directly ciphering input signals. CONSTITUTION:A cipher code 1100 is directly mixed into the input signal 1000 and a secret signal 1200 is obtained. To the input signal 1000, the secret signal 1200 is maintained as it is when the cipher code 1100 is '1' and is inverted when the cipher code 1100 is '-1.' That is, the secret signal 1200 is inverted in sections B1400 and D1600 and as a result, for the ciphered signals, a frequency band is widened and a noise proofing property is improved. The cipher code 1100 is calculated with the code of a certain series (code value: 1, -1) as the cipher code and infinite combinations are present for the code depending on a calculation method. Thus, since the pattern of a code string used for the cipher code 1100 can be inifinitely generated, the signals undecipherable for the third person are generated. On a reception side, when the same cipher code is mixed in again, the original signals are deciphered and the improved signals are obtained.

Filed: 1988-05-30
Abstract: PURPOSE:To initialize a magneto-optical disk uniformly in a short time by placing the magneto-optical disk in a magnetic field generated from a magnetic field generating means, and arranging the magnetizing direction of the disk. CONSTITUTION:Two coils 22 and 24 which generate the magnetic field are arranged oppositely keeping prescribed distance, and the magneto-optical disk 20 is placed between the coils 22 and 24, and the strength of the magnetic field generated in the coils 22 and 24 are set at the one required for the initialization of the disk 20. In other words, a current is permitted to flow on the coils 22 and 24 so as to generate the magnetic field larger than the coercive force of the recording medium of the disk 20 at a room temperature. And when the magneto-optical disk 20 is initialized, the magnetization of the disk 20 can be arranged in a moment along the magnetic field by generating the magnetic field by permitting the current in the same direction to flow on the coils 22 and 24. In such a way, it is possible to initialize the magneto-optical disk uniformly in an extremely short time.
