Title: Medium for floppy disk device
Inventor: TAJIMA TOMOYUKI
IPC: G11B5/41
Filed: 1989-06-30
Abstract: PURPOSE:To use the slider surface of a magnetic head always in a clean state by constituting the above device in such a manner that the stains, etc., of the slider part of the magnetic head can be wiped away in the part where the friction force of the medium surface and the magnetic head increases. CONSTITUTION:When the command control device requests a cylinder as an object, the medium is sought up to the wiping part 4 of either the outermost peripheral track side or the innermost peripheral track 2 side and is rotated several times before the magnetic head comes to a desired track (this track is the point where data is recorded or the data is to be recorded and, therefore, the track exists between the outermost peripheral track 1 and the innermost peripheral track 2). The stains are then wiped away to the wiping part 4 side and the slider surface of the magnetic head is eventually cleaned. The magnetic head is thereafter sought to the desired track. The cleaning effect of the magnetic head by the medium itself is enhanced in this way.

Title: Working method for deep groove by arc air gouging
Inventor: KOMATSU TAKASHI
IPC: B23K9/013
Filed: 1985-07-31
Abstract: PURPOSE:To obtain the required shape of a deep groove while eliminating the projecting part to remain on the base of the groove by arc air gouging by devising the arc direction of arc air gouging and the action of a gouging head to repeatedly continue the gouging. CONSTITUTION:The direction of the arc is always kept directed to the extension direction of the deep groove 1 of a work 5. The gouging head 7 is moved in an arrow D direction in the stage of starting the working of the groove. Electric current is conducted to a carbon rod electrode 6 where said electrode comes to the right end of the required deep groove 1a or compressed air is fed to start the working. The gouging head 7 is moved in an arrow C direction to form the shallow groove at the point of the time when an arc discharge arises. A turning roll 11 is rotated at a specified angle in an R direction upon completion of the working in the direction C and again the working is progressed in an arrow D direction. The working in the extension direction of the deep groove 1a is thus progressed by alternately using a parallel weaver 9 and the turning roll 11. The shallow groove of the 1st layer is completed when the work 5 makes one turn.

Title: Pen for input device
Inventor: OTANI MITSUHIRO
IPC: G06K11/06
Filed: 1984-08-11
Abstract: PURPOSE:To eliminate a feeling of the troublesome upward/downward movement of a pen and improve writing performance and operativity by operating a 1st-stage switch when pen pressure is weak and a 2nd-stage switch when strong, and detecting the pen force in two stages. CONSTITUTION:The flexion part 3a of a rubber switch 3 flexes under the push pressure from a pen shaft 2, and the contact 3c of the switch 3 is pressed against to opposite electrode parts 4b of an electrode plate 4 to cause electric conduction between the opposite electrodes, so that the 1st switch turns on. Further, when the push pressure from the pen shaft 2 increases until it exceeds the force of the spring 7 for the 2nd switch, a slide occurs between the united body of a pen shaft holder 13 and a switch housing 14 and the united body of a substrate housing 15 and a case 16 to press an electrode 6 against a contact 5, and consequently electric conduction is caused between the counter electrodes of the electrode plate 6 to turn on the 2nd-stage switch. Thus, the pen pressure is detected in two stages.

Title: Washing machine
Inventor: YAMASHITA TETSUJI
IPC: D06F33/02
Filed: 1989-06-30
Abstract: PURPOSE:To suitably realize the automatic execution of washing based on reservation by providing a atmospheric pressure detecting means to detect atmospheric pressure, weather forecasting means to forecast weather based on the transition of the detected atmospheric pressure and washing execution control means to control the execution of the washing caused by the reservation based on the forecasted weather. CONSTITUTION:When it is reserved at 6 o'clock in the afternoon to finish the washing at 6 o'clock in the next morning, a washing execution control part 7 determines time to start the washing at 5 o'clock in the morning, for example, based on the capacity of laundry in a washing tank detected by a capacity sensor 13 and starts monitoring time based on signals from a timer 9. At 10 o'clock in the evening before 8 hours to the 6 o'clock in the morning, the washing execution control part 7 forecasts the weather at 6 o'clock in the morning based on a forecasting principle that it is fine/ cloudy after 8 hours by a weather forecasting part 1 since the present atmospheric pressure is higher than a minimal value before 5 hours by 7mb and it is rainy (snowy) at that time. As a result, when it is fine, the execution of the washing is automatically started at 5 o'clock in the morning according to the reservation. In the case of rain, however, the reservation is canceled and the washing is not executed.
