Title: Spindle motor
Inventor: MOCHIZUKI MASANOBU
IPC: H02K1/32
Filed: 1984-07-30
Abstract: PURPOSE:To reduce the size of a spindle motor by opening cooling holes at the bottom of a rotor of the motor. CONSTITUTION:Cooling holes 7 are opened as cooling means instead of a fan at the bottom of a rotor 3 of a spindle motor 2. Thus, the holes 7 are opened at the bottom of the rotor 3 to eliminate the increase in the entire volume due to the projection of the conventional fin, to reduce the size and to provide cooling capacity equivalent to that of the conventional one.

Inventor: OTSUKA YASUMASA
IPC: G03G15/20
Filed: 1998-06-08
Abstract: PROBLEM TO BE SOLVED: To prevent such a failure as sticking of recording material around a pressure roller caused by accumulation of the toner dirt, or soiling recording material by the toner dirt accumulated on the pressure roller simultaneously parting therefrom, by means of restraining the accumulation of the toner dirt with respect to a fixing rotary body. SOLUTION: This fixing device is allowed to detect the temp. of a fixing nip part N by a thermistor 21 attached to a ceramic heater 20, after allowing a section heated in the fixing nip part N between the pressure roller 26 and the fixing film 25 to be shifted from the fixing nip part N. Since the respective section on the pressure roller 26 and the fixing film 25 being unheated is adopted, measuring is made possible to be correctly performed.  By performing the temp. control (first temp. control) setting the post rotation temp. control at 165 deg.C, the post temp. control at 200 deg.C for 5 sec the fixing nip section temp. when performing the subsequent printing below 100 deg.C (first temp. control value), it is made possible to reduce the toner quantity stuck on the pressure roller 26 below a half, therefore the generation of soiling by the toner can be restrained even in the case of the intermittent durability test even for 4000 sheets.

Title: Device and method for generating three-dimensional data
Inventor: BAN SHINICHI
IPC: G06T17/00
Filed: 1999-06-07
Abstract: PROBLEM TO BE SOLVED: To generate appropriate distance image data from two-dimensional image data. SOLUTION: An area dividing part F11 divides the image of a human head regulated by two-dimensional color image data DC1 into a background film area, a two-dimensional skin area and the other area that primally becomes a hair area. Then, while a switching part F13 switching converting methods, a partial distance image generating part F12 converts each area into a partial distance image. The background film area is converted into a partial distance image where height from a reference plane is zero, and the two-dimensional skin area and the other area are converted into partial distance images by converting luminance into height from the reference plane by a prescribed operation method. Thus, each area is converted into an appropriate partial distance image, and appropriate distance image data are generated.

Abstract: PURPOSE:To measure the air-fuel ratio quickly and highly accurately in a wide measuring range from rich to lean, by using an oxide semiconductor sensor only on the rich side and switching to a threshold current type oxygen sensor on the lean side. CONSTITUTION:An output of a thermocouple of a TiO2 sensor 1 is introduced into a temperature regulator 23 through an automatic cold junction compensator 19, a measuring amplifier 20, an attenuator 21 and an automatic cold junction compensator 22. A characteristic of resistance of TiO2 to the air-fuel ratio is changed suddenly in about 10<4> times at a boundary of rich and lean. Accordingly, its middle value is set at the standard resistance in a standard resistance setting device 29 and on the other hand, dimensions of the resistance of the sensor are extracted by a temperature compensator 25 and then, both dimensions are compared by a rich and lean decision device 30. When the sensor resistance is small, it is decided as rich and when said resistance is large, it is decided as lean. A threshold current type oxygen sensor 6 is connected to a threshold current voltage and current detection part. The voltage is applied only in case of deciding as lean by the device 30.
