Title: Removal of protrusion on semiconductor substrate
Inventor: HIGUCHI TOYOSHIGE
IPC: H01L21/304
Filed: 1989-11-15
Abstract: PURPOSE:To prevent a flaw from being produced on the surface of a substrate by pressure-destroyed wastes produced in a removal process and to reduce a defect rate of products by a method wherein a semiconductor substrate is immersed in an oxidizing solution, an oxide film of 100Angstrom  or lower is formed on its surface and an abnormally grown protrusion is pressure-destroy by using a press and is removed. CONSTITUTION:When an abnormally grown protrusion 1a generated on a vapor- grown semiconductor substrate 1 is pressure-destroyed by using a press 6 and is removed, the semiconductor substrate 1 is immersed in an oxidizing solution and an oxide film of 100Angstrom  or lower is formed on the surface of the semiconductor substrate; after that, the protrusion is removed. Thereby, the oxide film formed on the surface of the semiconductor substrate acts as a protective film; it is possible to prevent a flaw from being produced in a removal operation by which the protrusion is pressure-destroyed by using the press and is removed; it is possible to prevent a strain from being generated on the surface of the semiconductor substrate; it is not required to remove the oxide film after a treatment and the operation efficiency is enhanced.

Title: Meter driving apparatus
Inventor: FUKUDA KAZUYUKI
IPC: G01D13/22
Filed: 1988-11-24
Abstract: PURPOSE:To make it possible to swing a pointer smoothly by operating the digital quantity which is proportional to an input quantity at every count-up of a time counter, computing the difference value between the digital quantity at this time and the digital quantity at the previous time, and judging a processing method. CONSTITUTION:Pulse signals and clock signals corresponding to the rotations of a wheel are inputted into an operating part. Then, a time counter 22 in the operating part counts up the time for every specified elapsed time. The counted value is stored in a memory 26. A frequency operating part 27 operates the frequency. In a subtracting part 28, the frequency at the previous time is subtracted from the frequency at this time, and the difference value is computed. In a judging part 30, whether the difference value is positive or negative is judged. In a judging part 31, whether the absolute value of the difference value is larger than a specified value or not is judged. When the difference value is positive, the processing is finished, and the increase in apparent frequency is prevented. When the absolute value of the difference value is larger than the specified value, the specified value between the digital value at this time and the digital value at the previous time is determined as the digital value at this time. When the absolute value is smaller than the specified value, the digital value at this time is determined as the output digital value. Therefore, the smooth swinging of a pointer can be obtained.

Title: Card for radio data communication
Inventor: YAMADA AKIRA
IPC: H04W92/08
Filed: 1996-11-08
Abstract: PROBLEM TO BE SOLVED: To prevent unauthorized call connection to cause communication abnormality due to the reception level drop of radio waves from a base station by receiving reception level information from a portable telephone set and limiting the operation of call origination to the portable telephone set corresponding to a call originating request from a computer when that level is lower than a prescribed value. SOLUTION: When the call originating request from a PC 2 is received by a PC side reception/analysis part 7, the reception level information stored in a reception level information storage part 5 is confirmed by a reception level information judge part 8 and it is judged whether that level is lower than the prescribed value or not. When the level is lower than the prescribed value, the call originating request from the PC 2 is made invalid by a call origination limit part 9 and afterwards, it is judged whether the setting of communication necessity setting part 11 is 'necessary' or not. When the setting is 'necessary', a message showing the limitation of call origination is prepared by a call origination limit report preparation part 12 and reported through a PC side transmission part 10 to the PC 2.  When the reception level is not lower than the prescribed value, the call originating request is reported through an up serial signal preparation/transmission part 6 to a portable telephone set 3.

IPC: F24F7/007
Filed: 1993-11-26
Abstract: PURPOSE:To obtain a ventilator which is simple for users to understand how to use it and easy and comfortable to use, by a method wherein a sound generating device is provided to generate signal sounds in response to operating signals instructing the ventilator main body to proceed to operation and the signal transmitting frequency is adjustable. CONSTITUTION:When a switch on an operating panel 20 of a main body or a tact switch on a remote control transmitter 9 is pressed, an operating signal is supplied to a sound generating device 18 and a transmitter generates a sound having a preset signal transmitting frequency for a specified period of time. As the signal transmitting frequency is adjustable, for example, within a range of 500Hz-2KHz, by a regulator, the sound generator 18 can generate a sound with a compass where the aged can catch it easily. Therefore, as the sound is in a compass where both youths and aged can catch it easily even if the sound level is relatively low, the response to manipulation of the switch can be easily confirmed. In the case walls 4 are made up of relatively hard materials such as reinforced concrete, etc., the frequency is previously lowered a little as the sound turns into high tinkling sound, causing users to feel it uncomfortable.

Title: Signature input method
Inventor: NAGAI TOSHIAKI
IPC: G06F3/048
Filed: 1988-11-25
Abstract: PURPOSE:To exactly decide the completion of signature by always supervising the floating time of a pen from pen pressure data, and comparing the floating time with prescribed reference floating time, and deciding it to be the completion of the input of the signature when the floating time exceeds the reference floating time, and fetching the pen pressure and coordinate data up to a final contact point as signature data. CONSTITUTION:The signature is signed on a signature board 10 by the input of a pen 20, and the pen pressure data and the coordinate data are taken in as the data at that time. These data are taken in continuously whether during a period in which the pen is in contact with the signature board 10 or during a floating period in which it is separated form the signature board 10, and are stored in a general memory. Then, when the floating time of the pen exceeds the prescribed reference floating time determined beforehand, it is decided that the input of the signature is already completed, and the pen pressure data and the coordinate data up to the final contact point before that are taken in as the signature data. Thus, only the correct signature data can be received electrically regardless of signing time.
