Patent JP-S6490961-A (JP)
Title: Refrigeration circuit
Inventor: MASUDA KIYOSHI
IPC: F25B1/00
Filed: 1987-09-30
Abstract: PURPOSE: To prevent deterioration of lubricant oil or seizure of a compressor by a method wherein an opening or closing valve in a bypass line is opened when a temperature of discharged gas of the compressor is increased or when a load is increased and the like and then refrigerant is supplied to an intermediate suction port of the compressor. CONSTITUTION: When a temperature of discharged gas of a compressor 21 is increased upon its energization due to a delay in a thermo-sensitive section 29 of a discharged gas temperature adjusting valve 26, this increased temperature is detected by a thermo-sensitive section 32, an electro-magnetic opening or closing valve 33 is opened through a driver 34, a part of refrigerant of low temperature flowed from a condenser 22 is returned back to an intermediate suction port 21a of the compressor 21 through the discharged gas temperature adjusting valve 26 and a bypass line 30 bypassing an intermediate cooling device 23 so as to perform a cooling operation.  In addition, when a temperature of the discharged gaseous refrigerant is increased by a variation in load caused by a compressor load signal 35, or a variation in load of a main cooling device 25 during operation and a starting or finishing of pump-down state of the main cooling device 25, the opening or closing valve 33 is opened. In this way, it is possible to prevent deterioration of lubricant oil for the compressor as well as its seizure and further to restrict hunting of temperature of liquid refrigerant at the inlet port of the expansion valve.

Title: Decorative plate holding clip
Inventor: SATO SEIICHI
IPC: F16B21/08
Filed: 1989-09-25
Abstract: PURPOSE:To increase holding force of a clip, and to reduce drop of the holding force due to repetition of use by projecting a pair of elastic feet having a circular cross section at a body of the clip, and also by forming a pointed end for inserting it into a hole through combining the tips of the feet together, and in addition, by forming the outer surface of the said elastic feet so as to be a tapered pointed shape. CONSTITUTION:On the outside of an inner cavity 16 in a body 12 of a decorative plate holding clip 10, a pair of elastic feet 14 is attached vertically to the bottom surface of a head 11. The elastic feet 14 have a circular cross section. A central pillar 13 and a pair of elastic feet 14 are combined as one body at their lower ends, and produce a pointed tip 15 for insertion. Furthermore, outer surfaces 14a and 14b of the elastic feet 14 are formed so as to be a tapered pointed shape. When the elastic feet 14 are inserted into a mounting hole, the whole surface of the elastic feet 14 bears an inserting resistance uniformly. Therefore, load applied to the elastic feet 14 during mounting and dismounting the clip changes gradually. Consequently, it is possible to increase the holding force of the clip, and in addition, to reduce the drop of the holding force due to repetition of use.

Inventor: UONO TOSHIAKI
IPC: A47B97/00
Filed: 1997-09-12
Abstract: PROBLEM TO BE SOLVED: To prevent a person taking shelter under a desk from being thrown out by attaching a holding bar horizontally to the underside of a top board of a furniture by means of a mounting means of holding bar. SOLUTION: Each of mounting means 4 is fixedly attached to the underside of a top board 5a of a furniture 5 such as a table or desk by means of fixing screws 6 or bolts to mount a holding bar 1 along the board 5a in parallel with a mount surface. If an earthquake takes place, a person gets into under the furniture 5 such as a table and holds on the bar 1, whereby the person is prevented from being thrown out of the furniture 5. And even if another furniture, ceiling or beam falls down onto the furniture 5, the body of the person can be protected from the falling matters. The holding bar 1 is most desirably attached to the central portion of the underside of the board 5a so that the board 5a covers a person taking shelter under a table or desk due to the vibration of earthquake even if there is a displacement between the person and the table or desk.  Thus the person can be prevented from being thrown out to ensure the safety of his body.

As for red light, cyanogen toner image is transferred and superposed on the yellow and magenta toner images. Thus, the excellent color copied image can be easily formed and the burdens of an operator in operation can be decreased.

Title: Edge detection device
Inventor: TAKACHI NOBUO
IPC: G06V10/147
Filed: 1994-09-19
Abstract: PURPOSE: To enable edge detection with high precision by reading in image signals of a just-focus image and a soft-focus image of an object and performing difference arithmetic between the signal of the just-focus image and the signal of the soft-focus image. CONSTITUTION: This device is equipped with a linear moving mechanism D which moves constituent elements and a photographic screen S of an image formation optical system L linearly along the optical axis. This mechanism D suppresses a shift in the position of a principal point P as the intersection of the optical axis O and screen S of the optical system L while kept perpendicular to the screen S. Even when the focus is adjusted by moving the photographing lens etc. of the optical system L, the mechanism D suppresses the fluctuation in the position of the principal point P, the intersection of the optical axis O and screen S, while kept perpendicular to the screen S. Thus, the optical system L never has fluctuations in the principal point P and obtains life-size magnification which does not vary even when the focus position is varied.  Besides, an image signal can be processed through one optical system and image signal processing, so that the just-focus image and soft-focus image can be photographed under the same conditions.

Title: Spindle motor
Inventor: OBARA RIKURO
IPC: H02K21/22
Filed: 1999-09-03
Abstract: PROBLEM TO BE SOLVED: To further reduce the size of a spindle motor, while securing rotational accuracy and rigidity secured. SOLUTION: This spindle motor involves two bearings 5, disposed between a rotating shaft 1a and a frame 4, each of which has an inner ring 5b with a width smaller than that of an outer ring 5a and the end surfaces of the outer rings 5a are made abut against each other. Generally, high dimensional accuracy is ensured in the outer ring and the inner ring of a bearing, therefore, assembling accuracy between two bearings 5 is achieved by making both the end surfaces of the outer rings abut against each other. The space formed between the inner rings 5b enables minute movements of the inner rings 5b caused by pressurizing the end surfaces of the inner rings 5b, when a spindle motor is assembled and absorbs minute shakings which is unavoidable in a bearing, thereby improving the rotational accuracy of the spindle motor after its completion.
