Title: Antenna unit
Inventor: TOKORO HIROYUKI
IPC: H01Q21/22
Filed: 1978-02-23
Abstract: PURPOSE:To remove easily multipath disturbing waves from both horizontal- surface and vertical-surface directions by equipping at least two antenna elements which are arranged on different horizontal surfaces fixed-distance away from a cross point and in the mutual-cross direction. CONSTITUTION:Two antenna elements A and B are arranged on the same horizontal surface at a distance of 2S, and antenna element C is between element A and B and perpendicularly to the straight line between A and B distances-S away from the cross point. After passing through switches 11 and 12, outputs of elements A and B are supplied to receiver 10 by way of phase shifter 14 and mixer 15. The output of element C is supplied to switch 12 from phase inverter 13. Under the stack effect caused by horizontal and vertical distance S between elements B and C, horizontal-surface reflected wave E1 and vertical-surface reflected wave E2 are led to a feeder. In inverter 13, the output of element C becomes out of phase and then mixes with the output of element B and, in consequence, a null angle is found which can be satisfied horizontally and vertically in terms of directional pattern, so that disturbing wavas can be removed definitely by facing the multipath disturbing waves to this direction.

Title: Tactile sensor
Inventor: KURIYAMA TOSHIHIDE
IPC: B25J19/02
Filed: 1984-02-07
Abstract: PURPOSE:To produce a robot hand sensor accurately measuring fluctuation of pressures at low frequency or constant pressures as well as their distribution upon contact surface by a method wherein a piezo-electric body and an insulating gate type field effect transistor are fixed on a base oscillating in the direction perpendicular to their surfaces. CONSTITUTION:A tactile sensor is composed of an oscillating base 1, a p type silicon substrate 2, a high concentration n type silicon source region 3, a high concentration n type silicon drain region 4, insulators 5, a source electrode 6, a gate electrode 7, a drain electrode 8 etc. while a gate electrode 9 is electrically insulated from all elements other than a piezo-electric body 10. When a conventional supersonic wave sensor made of a piezo-electric body and an insulating gate type field effect transistor is fixed on a robot hand as a tactile sensor, the response characteristics to an object is that output is rapidly decreased by time lapse entirely out of proportion to the pressure. On the other hand, this tactile sensor oscillating itself can alternately fluctuate the pressure per object. The alternate amplitude of drain current of the insulating gate type FET may be made accurately proportional to the pressure by means of setting up the oscillating cycle of this sensor sufficiently shorter than the polarization attenuation time of piezo-electric body.

Filed: 1998-01-14
Abstract: PROBLEM TO BE SOLVED: To provide the communication system where a reception station can surely recognize as to what files are sent by multiple-address communication and a satellite channel is effectively utilized. SOLUTION: A Web server 21 of a transmission station 20 sends a file list denoting files which are to be sent by multiple-address communication to a reception state via a general public telephone network 60 (or satellite channel) before a file is sent to a plurality of reception stations 31, 32,..., 3n by multiple- address communication via a satellite 10. The transmission station 20 confirms that the corresponding reception state receives the file list, and then it sends the file by multiple-address communication via a satellite channel. Each of the reception stations 31, 32,..., 3n compares the received file with the file list to surely recognize whether or not the reception of the file is finished. When the reception is not finished, each reception station makes a request to the transmission state 20 for re-transmission of the file via the general public telephone network 60.

Title: Comb for resin sealed semiconductor device
Inventor: SUIZU SATOSHI
IPC: H01L23/50
Filed: 1982-02-10
Abstract: PURPOSE:To remove instability in case of the assembly process of rectilinear both ends of a hanger, and to obtain the stability of horseshoe-shaped both ends of the hanger while reducing stress applied to a resin material by the difference  of the thermal expansion of the resin material and a comb material by forming  the comb shapes of the end sections of the hanger to wedge shapes. CONSTITUTION:The difference of the thermal expansion of the resin material and the comb material is generated through solder dipping, and force F is applied to the resin material 4. However, force applied to the wedge shapes 22 is Fsintheta (where theta is the angle of an opening of a wedge) because the comb form of the hanger 2 takes the wedge shapes 22. Consequently, said force is sintheta times as large as force F applied in case of a horseshoe rubber. Accordingly, the acceleration of an MTTF in the case when the whole is dipped into a solder tank at 260 deg.C for ten sec can be limited up to six times when the angle of the opening of the wedge is 30 deg. and up to approximately two times when the angle of the opening is 10 deg..

Title: Semiconductor device having wiring layer
Inventor: MINOWA MASAYUKI
IPC: H01L21/3205
Filed: 1988-01-29
Abstract: PURPOSE:To flatten an interlayer insulating film and to prevent a short circuit between wiring layers due to a stress of a resin even under an environment of an extreme temperature change by arranging an unconnected part in a vacant region where an interval of the wiring layers arranged on a semiconductor substrate is wider than a minimum wiring interval decided by a production process. CONSTITUTION:Because a dummy wiring layer 10 is arranged in a vacant region in this semiconductor device, a wiring interval of lower-layer wiring layers 2 can be set to be equal to a minimum wiring interval decided by a process in a whole region where an upper-layer wiring layer 4 is spread. Accordingly, an interlayer insulating film 3 is flattened in the whole region where the upper-layer wiring-layer 4 exists; a large stepped part does not exists in the upper-layer wiring layer 4. As a result, a disconnection of the upper-layer wiring layer 4 can be prevented. Even when a resin 7 is slipped due to a stress of the resin 7 and the upper-layer wiring layer 4 is moved in the direction of an arrow, the lower-layer wiring layers 2 and the interlayer insulating film 3 are not moved; accordingly, it is possible to avoid the situation that a crack is produced in the interlayer insulating film and that a short circuit is caused between the wiring layers 2, 4.
