Title: Magnetic brush developing device
Inventor: SOUMA SHINOBU
IPC: G03G15/09
Filed: 1984-12-21
Abstract: PURPOSE:To control the thickness of a developer layer smoothly and accurately by arranging the magnetic poles of a magnet body nearby a doctor blade at its downstream side, and providing the 2nd gate member of the same constitution with the 1st gate member at the downstream side so that the 2nd gate member is interlocked with the 1st gate member. CONSTITUTION:When a recording device such as a copying machine is not in operation, the 1st gate member 7 and the 2nd gate member 8 of a developing device 2 are positioned nearby a developing sleeve 3. Then, an image carrier 1 begins to rotate and a latent image forming means forms a latent image on the surface. The rotation of the developing sleeve 3, etc., is started and the 1st gate member 7 and the 2nd gate member 8 are moved back so that the developer layer is formed on the developing sleeve 3 before the latent image formation surface reaches a development area. When the latent image formation surface finishes passing through the development area, the 1st gate member 7 comes close to the developing sleeve 3 firstly and then the 2nd gate member 8 approaches the developing sleeve 3 and returns to its original position. Consequently, the wear of the image carrier and the consumption of a developer are reduced to lighten the load on a cleaning device, thereby preventing a stain from sticking inside the recording device and a no-image part on recording paper, etc.

Title: Rotary machine
Inventor: KITAMURA SHUICHI
IPC: F04C18/20
Filed: 1986-11-13
Abstract: PURPOSE:To improve thermal efficiency of the rotary machine in the caption by holding a rotating body in contact with the inside peripheral surface of a rotating hollow body and varying the conditions where a switching port is connected to a control port while rotating the rotating body. CONSTITUTION:When the pressure in a low-pressure passage 14 is reduced by a throttle valve, or the capacity of a pump is controlled by opening a relief valve 15, a rotating body 17 in a rotating hollow body 9, makes circular motions in response to the above controls to a specified position. Consequently, the start time for connecting a switching port 10 to a control port 18 is delayed a specified period of time, and the start time for connecting an actuation chamber 8 to the inside of the rotating body 17 is also delayed a specified period of time. Thus, when the pressure in the actuation chamber 8 reaches near the pressure on the high-pressure side, the fluid is discharged into the rotating body 17. As a result, even if the pressure in the low-pressure passage 14 and/or the rotating hollow body 9 is varied, lowering of the total heat insulating efficiency can be prevented since the control position of the rotating body 17 is varied.

Title: Method for measuring electron spin resonance
Inventor: MURAYAMA SEIICHI
IPC: G01R33/60
Filed: 1991-10-17
Abstract: PURPOSE:To provide an accurate resonance spectrum at a high ratio of S/N by taking a difference between photoelectric currents for light with two frequencies which are generated in a pair. CONSTITUTION:One photon emitted from a laser 1 is converted into two photons with different frequencies, nu1, nu2 (nu2>nu1), by using a wave-length converting means 2 to allow the entry of a set of photon beams to the same position of a specimen 4 to which a magnetic field is applied by a field applying means 3. The photons with frequencies nu1, nu2 which transmits the specimen 4 is guided to two different optical paths which are separated by an optical path separating means 5 and detected by detectors 6-1, 6-2 which are located on the terminal of the respective optical paths to find a difference signal of output photoelectric currents through a difference signal generating section 7. It is thus possible to suppress quantum noise and selectively detect only a change in condition that the photons has mutual action with the specimen 4.

Title: Airflow direction deflecting device of air conditioner
Inventor: MIYAHARA SHINJIRO
IPC: F24F13/08
Filed: 1984-12-21
Abstract: PURPOSE:To cause the airflow direction to oscillatory swing by automatically oscillating a pair of rotatable airflow deflecting plates by linking one of the airflow deflecting plates to the air guide with shape memory alloy and an auxiliary spring and connecting the airflow deflecting guide with each other by a connecting rod. CONSTITUTION:The hot air is caused to pass near the shape memory alloy 27 by deflecting the hot air which has passed the heat exchanger 23 toward the adhering wall 25 by the Coanda effect between the airflow deflecting plate 30 and the adhering wall 25 which is obtained by rotating the front end of the airflow deflecting plates 30, 30' toward the adhering wall 25. Then, a contracting force is generated in the shape memory 27 which causes the rear end of the deflecting plate 30 to rotate toward the rear end of the deflecting plate 30 to rotate toward the air guide 26. As the airflow direction is deflected toward the adhering wall 25', the temperature near the shape memory alloy 27 is decreased. As a result, the contracting force of an auxiliary spring 28 becomes larger than that of the shape memory alloy 27, and so, the airflow deflecting plate 30 returns to its original position. Such motion is automatically repeated.

Title: Manufacture of semiconductor device
Inventor: YAMAGUCHI TSUTOMU
IPC: H01L21/338
Filed: 1989-10-16
Abstract: PURPOSE:To shorten electrode length largely by utilizing an eave-shaped section formed at the end edge of a resist pattern under the state in which the eave- shaped section is overhung toward the outside in a process in which a dielectric layer is deposited onto the resist pattern. CONSTITUTION:A first dielectric layer 3 is shaped onto the surface of a semiconductor substrate 1 in desired thickness, and a second dielectric layer 4 is deposited onto the surface of the layer 3. Consequently, the first dielectric layer 3 formed onto the surface of a resist pattern 2 shapes an eave-shaped section 3a overhung to the outside at the end edge of the resist pattern 2. As a result, when the second dielectric layer 4 is deposited, the second dielectric layer 4 is deposited to a section except a section covered with the eave-shaped section 3a, but the layer 4 is not deposited to the section covered with the eave-shaped section 3a, thus forming a region 3b in which the first dielectric layer 3 is exposed as it is. Accordingly, when the first dielectric layer 3 is etched while using the second dielectric layer 4 as a mask, an opening 5 in which the surface of the semiconductor substrate 1 is exposed can be shaped under the eave-shaped section 3a.
