Title: Electromagnetic clutch and manufacture of the same
Inventor: KANAMARU NAONOBU
IPC: F16D27/14
Filed: 1979-05-25
Abstract: PURPOSE: To improve heat resistance of the electromagnetic clutch, by inserting between a pair of disk plates a connecting member made of non-magnetic material having a higher resistance to deformation than the disk plates and formed with grooves in its peripheral surfaces, and then pressing the disk plates with a metal die.  
     CONSTITUTION: Between inner and outer disk plates 221 and 222, there is inserted a connecting member 223 substantially in the form of a ring, which is formed with grooves 223b in its peripheral surfaces and made of non-magnetic material having a higher resistance to deformation than the disk plates 221, 222. These inner and outer disk plates 221, 222 are connected mechanically with each other by pressing end portions of disk plates 221, 222 with metal die 50 and thereby urging the same into grooves 223b of the connecting member 223 by way of plastic deformation. By employing such a manufacturing method, leakage of magnetic flux can be minimized since there is no ineffectual magnetic passage. Further, since the material having high heat resistance can be used for the connecting member, disk connecting force can be maintained if temperature of the disk portion 7 is raised due to trouble like lock of compressor.

Inventor: ANDO MICHINORI
IPC: G06T7/00
Filed: 1998-02-28
Abstract: PROBLEM TO BE SOLVED: To more accurately obtain an area image by performing the extracting processing of the area image while using only an area process even when the value of a determinant becomes zero. SOLUTION: A demultiplexer 15 sends the area image information of an image area memory 2 while switching it to an area image estimating part 16 due to a first estimating means or an area image estimating part 17 due to a second estimating means based on the signal of a determinant discriminating part 14 for a correlative matrix. When the value of the determinant is any value other than zero, the area image estimating part 16 estimates the next intermediate area image through the area process and a texture process based on the area image information in the area image memory 2, texture image and parameter obtained by a parameter estimating part 13 and transmits the area image information to a multiplexer 18.  When the value of the determinant is '0', the area image estimating part 17 estimates the next intermediate area image through the area process while estimating the parameter of the area process from the area image information in the area image memory 2 and transmits the area image information to the multiplexer 18.

Title: Brake assisting apparatus
Inventor: SAITOU NAOICHIROU
IPC: F16D65/28
Filed: 1980-05-15
Abstract: PURPOSE:To simplify constitution and improve response by connecting a brake assisting apparatus so that a main cylinder operates in the direction of brake band tightening in proportion to the generated pressure of a pilot cylinder. CONSTITUTION:When a pedal 36 is stepped on, a piston 32 shifts rightward, and  also a piston 33 shifts rightward. The piston 33 shifts rightward by the amount of  play in a band 21 and a lever 22. When the shift of piston 33 covers the play completely, a pilot pressure P1 is generated in a pilot cylinder 34, forcing the band 21 to  be tightened by the pressure P1, while the pressure P1 is transmitted to a cylinder 39. When the pressure P1 exceeds the pressing force of a spring 44, a piston 43 shifts rightward, to force a proportional pressure control valve 25 to be operated through a rod 45, and thus a secondary pressure P2 is generated. A main cylinder 23 is operated by the secondary pressure P2, and the lever 22 is turned counterclockwise, to tighten the brake band 21, and thus brake power is generated.

The surrounding frame 8 is moved vertically and horizontally for adjustment by a crane, etc., and when outputs of voltmeters 28 responding to outputs of displacement gauges 25 at eight positions become equal, fitting to a wind guide 4 is accomplished with a fitting bolt 11. Thus, centering work is carried out easily and rapidly with high precision.

A rod 23 is inserted through the rod guide hole 14 so that it is movable forward and backward in the axial direction, and one end face thereof is brought into contact with the center of the lower side of a diaphragm 32 of the power element 30.  In this case, the diametral dimension of the rod guide hole 14 is set in a range not exceeding the dimension obtained by adding 0.02 mm to the diametral dimension of the rod 23 and thereby a play between the rod guide hole 14 and the rod 23 is diminished.

Title: Calling system for branch telephone circuit
Inventor: KAJIMA KATSUICHI
IPC: H04M9/02
Filed: 1981-04-27
Abstract: PURPOSE:To call many telephone sets individually by one branch transmission line by using control frequencies which correspond to the dial numbers of the telephone sets. CONSTITUTION:A dial signal and a voice signal from a telephone set 3b are separated by the telephone-set repeater circuit of a coupler 6b. The voice signal is sent to a coupling circuit 13 via a signal line 12, and the dial signal is sent to a control circuit 15 through a signal line 14. The control circuit 15 converts the dial signal into a control signal fn in a voice frequency band, and the fn is sent out to the coupling circuit 13. The fn is combined with the voice signal by the coupling circuit 13 and the resulting signal is sent via an output terminal 8 to a branching device 2b', from which it is sent to another branching device 2n' through a telephone circuit 1. The branching device 2n' sends this signal to the input terminal 7 of a coupler 6n. The signal is sent to a separating circuit 18, which separates the input signal into the voice signal and control signal, which are sent to the telephone-set repeater circuit 11 and a control circuit 15. The control circuit 15 judges that the control signal is a signal fn for calling the  telephone set of its station, thereby calling a telephone set 3n.

In this case, it is sufficient if devices R and R' are connected directly to output terminls 5 and 6. The impulse due to switching of the relay contact 2 is absorbed by a buffer circuit 7, and currents of power lines 3 and 4 do not by-pass the buffer circuit 7. Consequently, the malfunction of return defect is not induced.

Title: Production of floor material
Inventor: HAYASHI MORIO
IPC: E04F15/04
Filed: 1990-03-15
Abstract: PURPOSE:To form recessed parts on a woody material and to impart a non-slip property thereto by applying a primer coat compounded with additives having poor compatibility with a coating material to the woody material, curing the coat and applying a top coat thereto, thereby forming a top coat film. CONSTITUTION:The primer coat compounded with the additives 2 having the poor compatibility with the coating material is applied on the woody material 1 and is cured to form the primer coat film 3. The top coat is then applied to the primer coat film 3 to form the top coat film 4, by which the floor mate rial is produced, Since the top coat film 4 is formed on the primer coat film 3 in the above-mentioned manner, so-called 'cissing' is generated in the top coat prior to curing by a difference in surface tension between the additives 2 and the top coat and the many recessed parts 5 are formed in the top coat film 4. The non-slip property is thereby imparted to the wooden material. The more adequate example of the above-mentioned additives 2 include additives of a silicone base.

Title: Original reader
IPC: H04N1/19
Filed: 1992-03-24
Abstract: PURPOSE:To reduce mutual interference between signals by applying time division to plural output signals and transferring the divided signals serially when output signals of plural A/D converters are transferred between signal processing units so as to decrease the number of cores of a cable. CONSTITUTION:Outputs from a CCD 4 are fed to A/D converters 6a-6e via five amplifiers respectively. A control signal is fed to converters 6a-6e from a digital signal processing unit 9 and outputs of the converters 6a-6e are fed to 5 gates 29a-29e. Then other control signal 28 is fed to the gates 29a-29e from the unit 9 and its output is transferred serially in time division. Thus, each output of the gates 29a-29e has 8-bits in total 40 lines and since the data are subjected to time division, the data line number of the cable 22 is 8 lines. A rearrangement circuit 25 transfers the data transferred serially to the signal processing circuit in the order corresponding to the arrangement of the CCD. Thus, the number of cable cores is reduced and mutual interference between signals is reduced.
