Title: Microwave oven with electromagnetic cooking utensil
Inventor: NOGUCHI HIROYUKI
IPC: H05B11/00
Filed: 1988-03-25
Abstract: PURPOSE:To prevent the danger of a burn and secure safety by providing a cover selectively covering the upper face of a top plate and preventing a pot or the like from being mounted on the top plate. CONSTITUTION:When no induction-heated cooking is performed, a cover 14 is extracted to cover the upper face of a top plate 3 at a gap 15. Under this condition, when a pot or the like is mounted, it is mounted on the cover 14 and not directly on the upper face of the plate 3. Even if the induction-heated cooking state is attained by an erroneous operation or a failure such as the contact deposition of a relay, a weight sensor detects that no pot or the like is mounted on the plate 3. A controller judges that no pot or the like is mounted on the plate 3 based on it and prohibits the execution of induction heating, thereby the pot or the like is prevented from being heated to an abnormally high temperature, and safety can be secured.

Title: Toner
Inventor: NAGAI TAKAFUMI
IPC: G03G9/087
Filed: 1998-03-20
Abstract: PROBLEM TO BE SOLVED: To prevent increase in charges without losing the insulating property of a toner. SOLUTION: Hydrophobic inorg. fine particles having 10<10> to 10<12> Ω.cm volume rersistivity and <=0.1 μm average particle size are added and fixed to the surfaces of color particles comprising at least a binder resin and a coloring agent and having 5 to 20 μm average particle size. The inorg. fine particles are added by 0.5 to 2 pts.wt. to 100 pts.wt. of the color particles. The obtd. toner has such a structure that the hydrophobic inorg. fine particles having the optimum volume resistivity are fixed to the surfaces of color particles, so that increase in the toner charges due to accumulation of charges or broadening of the charge distribution are hardly caused even when the toner is used for a long time, and the toner has excellent electric insulating property in a high humidity environment.  Therefore, the obtd. toner shows little dependence on the environment and excellent stability of an image density and transfer efficiency.

Title: Ccd camera and its illuminance correction method
Inventor: YAMATO YOICHI
IPC: H04N5/222
Filed: 1995-03-07
Abstract: PURPOSE: To make the camera light and small by providing a reference picture element area for monitoring uneven illuminance to one end of the main scanning line of an image sensor and applying illuminance correction to object image data based on a difference between the reference area illuminance detection value and an optimum value. CONSTITUTION: An illuminance lamp driven by a commercial AC power supply generates uneven illuminance. A few picture elements at a head end and a tail end of a CCD line image sensor in a main scanning direction are selected for reference areas A, C, and picture elements between the reference areas are used for an image forming area B of an original image. Data in the area A (or C) are given to a correction value arithmetic section 72 via a selector 62, a data latch section 64 (or 66) and a selector 70, in which a difference ΔV between the data and an output VOP inputted in advance at an optimum illuminance is obtained. Picture element data on the image forming area B are given to a correction arithmetic section 74 via the selector 62, in which the difference ΔV is added to the data.  Thus, read data at a point of time when fluctuated illuminance is in existence are corrected by read data at an optimum illuminance. Thus, a highly accurate DC or high frequency power supply for driving a lamp is not required.

Title: Shower device
Inventor: HIRAISHI KAZUO
IPC: A47K3/28
Filed: 1990-03-20
Abstract: PURPOSE:To enhance usability by memorizing the value of a flow rate, the setting of which is changed at the time when water discharge is suspended, for respective shower units, in a control section for a definite period of time, and thereby starting discharge water at the flow rate whose setting has been previously changed (final flow rate value) when the shower units are used again within a definite time. CONSTITUTION:A separate shower B is selected so that water discharge is started with a shower A suspended. After it has been used for the specified period of time while the setting of a flow rate is changed to a value lower than the pre-set value halfway, the shower A previously used is selected again so as to be used with the shower B suspended. In this case, a timer means 39 has started counting at the time when the shower A was suspended. If the shower B is selected so as to be reused within the definite period T of time after counting has been started, it is directed by a read-out means 40 that the value of a final flow rate, that is, the flow rate value whose setting has been changed, is outputted to a comparison means 38 out of a memory means 37. This permits the flow rate of the shower A at the time of reuse to be equivalent to one which has been used, thereby starting water discharge with a flow rate adjusting section 15 or 16 controlled.

Title: Capstan winch
Inventor: OGAWA TERUO
IPC: B66D1/74
Filed: 1989-03-25
Abstract: PURPOSE:To enhance the extent of safety in performing tailing manual operation mechanically by installing a function for synchronously rotating a capstan and an acute deep groove sheave at time of winding rotation and another function for adding frictional force to this sheave by a slip clutch and giving it back tension at time of capstan delivery rotation, respectively. CONSTITUTION:At time of normal rotation in a load state with load added to a wire or the like, there is added a larger tension than a tension spring, so that an interval between a sheave 44 and a capstan 1 comes to tenseness at all times, and thereby the wire or the like will not entangled in the capstan due to wrong winding. Next, at time of delivery operation (reversing time) in an unloaded condition, if the capstan is rotated to the delivery side, a first one-way clutch built in the capstan comes free, and an acute deep groove sheave 3 is connected to an inner shaft and a slipping clutch 34. Consequently, in the wire or the like, friction works on the acute deep groove sheave with this clutch 34, thus back tension is produced there all the time.
