Title: Microwave variable delay unit
Inventor: HONMA MASAJI
IPC: H01P1/202
Filed: 1977-12-26
Abstract: PURPOSE:To obtain a small-size delay unit which can increase the delay time without lowering the transmission quality by using the microwave filter which varies the band width to vary the band width of the filter and thus performing the variable control for the delay time. CONSTITUTION:Microwave filter 1 is used to vary the band width of the microwave, and the band width is limited to cause the phase rotation. Thus, absolute delay time which is reversely proportional to the band width owing to the secondary component of the phase frequency characteristics is obtained. Filter 1 of such constitution is turned to the reflective filter, and compensator 10 comprising the 2-step filter of close connection is connected to the output side of circulator 2 combined to filter 1. Thus, the deterioration of the frequency characteristics can be compensated for the delay time which is caused when the delay time is increased.

Title: Cursor control method
Inventor: WATANABE HISAAKI
IPC: G06F3/038
Filed: 1987-06-24
Abstract: PURPOSE: To move a cursor even at the time during separating and thereafter returning a mouse from and to the surface by adding a function which aritificially calculates the extent of movement of the cursor from an output value at just before the time when the output value of the mouse is 0.  
     CONSTITUTION: When the extent of movement of the mouse is 0, in case of a moving mode, the extent of movement in the preceding stage is calculated in accordance with the moving mode, and the cursor is moved by a corresponding extent. If the moving mode is not set, the cursor is stopped. Whether the moving mode is set or not is discriminated by states of functional switches attached to the mouse. By this constitution, this method can cope even with the case of cursor stop to be desired, and by setting plural modes of constant speed movement and attenuation movement, this method can cope with plural requests to the movement pattern of the cursor, and the time required for pointing is shortened.

Filed: 1996-06-19
Abstract: PROBLEM TO BE SOLVED: To provide a photoreceptor life detecting method capable of surely detecting the photoreceptor life in all developing conditions and device environments by simplifying the constitution of a device. SOLUTION: While a photoreceptor drum 1 keeps practically usable performance, grooves 2a formed in a CT layer are clogged with the remaining toner 3, and the toner 3 remains on the photoreceptor drum 1 as a toner pattern without being scraped out with a cleaning blade 4. A user seeing this state confirms that the life of the photoreceptor drum 1 remains. When the photoreceptor drum 1 approaches its life, the CT layer of the drum 1 is scraped off and made thin, and grooves 2a disappear at last. After that, the remaining toner 3 is completely scraped out with the cleaning blade 4, and the toner pattern disappears. Since the thickness of the photosensitive body film is equal to the minimum thickness for keeping practically usable performance, the user recognizes that the life of the photoreceptor drum 1 is finished by seeing the disappearing of the grooves 2a.
