Filed: 1984-12-06
Abstract: PURPOSE:To obtain a magnet having a high magnetic characteristic at a low cost by alternately disposing a plurality of high magnetic flux density magnets made of an inter-metal compound magnetic material and a plurality of low magnetic flux density magnets made of an oxide magnetic material and integrally joining them with each other. CONSTITUTION:A high magnetic flux density is obtained in the portions of high magnetic flux density magnet 1 made of an inter-metal compound magnetic material, and the magnetic flux density is low in the portions of low magnetic flux density magnet 2 made of an oxide magnetic material. Therefore, if magnetic poles are made in the high magnetic flux density magnets, and the portions of low magnetic flux density magnet are positioned between the magnetic poles, a sufficient magnetic flux density is obtained in the portions where a high magnetic flux density is required, and it is unnecessary to use an expensive magnetic material in the portions where a high magnetic flux density is not required.

Filed: 1997-09-24
Abstract: PROBLEM TO BE SOLVED: To set an optimum cleaning condition with respect to a device ambient temperature by changing an abutting angle formed by a tangent on a position where a cleaning blade abuts on an image carrier and the contact surface of the cleaning blade on the abutting position. SOLUTION: A supporting member 14 on which the cleaning blade 11 is fixed is supported by the arm 15a of an angle adjusting member 15 and an angle guide plate 16. The member 15 can rotate the member 14 by the angle of about 20 deg. centering the abutting position of the blade 11 and a photoreceptor drum 1 by the plate 16. Thus, the entering amount of the blade 11 to the rotating drum 1 is stabilized, so that abutting pressure is kept nearly constant. In this case, the abutting angle of the blade 11 can be changed through the member 15 while the abutting pressure of the blade 11 to the photoreceptor 1 is kept constant in accordance with the change of the particle size of toner.

IPC: B05B1/30
Filed: 1989-10-05
Abstract: PURPOSE: To lessen the wasteful consumption of an adhesive by providing a spray apparatus with a means for continuously discharging material and a means for depositing the material on a substrate. CONSTITUTION: The molten hot melt adhesive is delivered through a gun body 12 of the spray apparatus 10 and is released via a nozzle accessory 18.

Title: Wireless communication system
Inventor: SHIBATA OSAMU
IPC: H04B10/25
Filed: 1999-09-13
Abstract: PROBLEM TO BE SOLVED: To realize a small-size inexpensive wireless communication system by considerably simplifying the configuration of a radio base station side. SOLUTION: In the wireless communication system where a radio base station with a variable directivity array antenna and a control station communicate with each other by means of an ROF, a signal of each element of the array antenna is frequency-converted into a plurality of signals with different frequencies, a reference signal whose frequency is apart from those of a plurality of the signals by a prescribed frequency is multiplexed on a plurality of the signals and the multiplexed signal is transmitted through the same optical fiber 112. According to this method, the number of electrooptic converters and photoelectric converters can be reduced and the configuration of the radio base station can considerably be simplified, then the inexpensive and small-sized wireless communication system can be built up.  Moreover, since all the signals are transmitted by using the single optical fiber 112, relative phase fluctuation due to expansion/contraction of each optical fiber on the way of transmission can be avoided in this configuration.

Title: Shielding structure and manufacture thereof
Inventor: NAKAJIMA KINSAKU
IPC: H05K9/00
Filed: 1992-09-29
Abstract: PURPOSE:To make an accurate contact of contact members by curling one end of contact members of one shielding board and by bending an end of the other shielding board (reception board) in the shape of L. CONSTITUTION:A group of contact members 7 are not bent at right angles but are bent a little wider opened upwards (X>90 deg.). An end of the group of contact members 7 is curled. Because of this reason, when a shielding board (reception board) 6 is pushed against the contact members 7 from above, the contact members 7 are brought into contact with the L-shaped bent part of the shielding board (reception board) 6. At that time, the group of contact members 7 are brought into contact with both a flat part and the L-shaped bent part of the shielding board (reception board) 6 or with either the shielding face 6a or the cross face 6b and therefore a shielding effect can be obtained stably. Even if the contact sections are not uniform, the contact members can be accurately brought into contact with at least one of the shielding face 6a and the cross face 6b.

Title: Control device for elevator
Inventor: TSUCHIYA TETSUHISA
IPC: B66B13/14
Filed: 1994-10-25
Abstract: PURPOSE: To prevent the load of the elevator by extending the door opening time limit over the preset value when the number of calls of the call button is counted to the value exceeding the preset number of calls within the prescribed period of time. CONSTITUTION: The number of calls of an elevator is counted (S21), and a judgement is made whether the number of calls is counted to the preset value within the prescribed period of time (S22). If the counted number of calls does not exceed the preset value, the counter is set and the normal operation is continued without any change (S27). When the counted number exceeds the preset value, switching is made to the extension operation of the door opening time limit (S23). The counter is once reset, and the number of calls is again counted (S24), and a judgement is made whether the number of calls does not exceed the preset value within the prescribed period of time, and when it exceeds, the operation is returned to S23 (S25), while in the case when it does not exceed, the operation is jumped to S26, the counter is reset, and the door opening time limit is returned to the original time limit at S27 to achieve the normal operation.

IPC: G06F9/30
Filed: 1985-11-20
Abstract: PURPOSE:To reduce a program scale and also to simplify an instruction control by designating the execution and the function in different fields and therefore reducing greatly the program size. CONSTITUTION:An instruction 10 to be controlled consists of the 1st and 2nd fields 11 and 13 which are independent of each other. Then the designation of execution carried out in the field 11 is decoded by the 1st decoding means 21. While the designation of function is carried out in the field 13 against the execution designation of the field 11. This function designation is decoded by the 2nd decoding means 23. Furthermore a memory means 30 holds the output of the means 23 until the function is designated again in the field 13. Thus the program size is greatly reduced. This attains the reduction of the program scale as well as the simplified control of the instruction.

Title: Sample table
Inventor: DOI TAKAHISA
IPC: H01J37/295
Filed: 1985-11-22
Abstract: PURPOSE:To easily make a sample rotatable and at the same time enable heating the sample at any angle by equipping a part set the sample on and a heating mechanism part independently for in-plane rotation, heating the sample indirectly and enabling the sample to rotate endlessly in the plane. CONSTITUTION:After a sample 1 is set on a cassette 2, it is attached to a sample table. The sample table is composed of a receptacle 3 for the cassette, a spacer 4 and a rotary table 5 and is attached to an arm 9 through a bearing 6. The in-phase rotation of the sample is introduced through a gear 7 from the exterior, but at this time a heating device 10 does not rotate. Current to the heating device 10 is supplied through a heating wire 8. For the reason that the gear or a belt wheel is attached directly to the rotary table 5 and the sample is observed while being heated in ultrahigh vacuum, materials with excellent heat resistance and little gas emission are used for the elements 2-6 being in the neighborhood of the heat source.
