Title: Path setting type router
Inventor: SAITO SHUICHI
IPC: H04L12/46
Filed: 1992-08-31
Abstract: PURPOSE:To select a proper communication path when plural communication paths are in existence between 1st and 2nd information processing units in a network comprising plural LAN equipments. CONSTITUTION:Addresses of destinations corresponding respectively to plural communication paths in existence between 1st and 2nd information processing units are stored in an address table 7. When a transmission reception control device 5 receives a transmission reception frame from the 1st information processing unit to the 2nd information processing unit, the path setting device 2 references the address table 7 to acquire an address of the destination corresponding to the communication path in existence between the information processing units. A path selection device 3 selects an address whose relevant communication path is normal and whose traffic is lowest among those acquired by the path setting device 2 and sends a path setting type transmission reception frame including the received transmission reception frame whose setting destination address is the selected address to a LAN equipment via an address control device 4 and a transmission reception control device 6.

Title: Magneto-optical recording/reproducing device
Inventor: KANEKO SHINJI
IPC: G11B7/005
Filed: 1994-10-21
Abstract: PURPOSE: To precisely demodulate a light intensity signal even when a current flowing through a photodiode being a photodetector is large by performing clamping operation so as to incorporate a data recording part and a part of an address part. CONSTITUTION: When a clamp output is demodulated by a comparator 83, its input is limited by a gate pulse GP, and only the data of the address part ADD are outputted from the comparator 83 as a gate output. Although only the data equivalent to the address part ADD are compared and demodulated in the comparator 83, since the regenerative DC level of the address part ADD is not changed so much at this time, the data are demodulated precisely from the initial address data ADD 2.

Title: Mobile communication equipment, fixed communication equipment, communication system and communication method
Inventor: SUGITA TAKEHIRO
IPC: H04W72/04
Filed: 1995-09-08
Abstract: PROBLEM TO BE SOLVED: To attain using the mobil communication equipment of a wide area communication system in an internal closed area communication system even at the time of a code division duplexing system by reducing a spread rate in a spectrum spread and transmitting a code division duplexing signal in terms of burst. SOLUTION: The speed of a timing signal given to an interleaver circuit 14 is made to be high so that the data speed of voice data S3 is made to be high and outputted in terms of burst. The voice data S3 is inputted to a spectrum spread circuit 15 and the spectrum spread is executed. At this time, the spread rate is reduced and the spectrum spread is executed. Thus, a chip rate is reduced so that a transmission signal S5 can be transmitted by the prescribed timing in terms of burst. A burst randomizer circuit 17 receives a timing signal from a timing generator 29 and fixes the burst position of the transmission signal S5 at the prescribed timing. Thus, the transmission signal S5 of time division, that is, a TDMA system is generated.

Filed: 1988-10-13
Abstract: PURPOSE:To reduce quantization distortion and to improve total characteristics by expressing a picture element vector having a large variance value by an index consisting of the small number of bits and expressing a picture element vector having a small variance value by an index consisting of the large number of bits. CONSTITUTION:The tree searching quantization of an inputted two-dimensional signal vector (x) is executed up to the 3rd herarchies to obtain an output vector ym expressed by an index im consisting of 3 bits and a deciding circuit 102 compares the variance value bm of the output vector ym with a prescribed value (s) and outputs a decision signal (h). When bm>s is formed at the time of receiving the decision signal (h), a quantizer 100 sends the 3-bit index im of the output vector ym as it is, and in the case of bm<=s, executes the searching quantization of the input signal vector (x) up to the 5-th herarchies and sends a 5-bit index in expressing an output vector yn. Consequently, the number of bits corresponding to the quantization of the picture element vector can be varied, the quantization distortion of using frequency can be reduced and the total characteristics can be improved.

Title: Earth contact
Inventor: MASUDA TAKAHIRO
IPC: H05K9/00
Filed: 1988-10-13
Abstract: PURPOSE:To absorb the vibration of a flat spring by friction of a contact part and to prevent a screaming sound caused by vibration by providing a slit extending lengthwise of the flat spring holding a contact tip coming into contact with a rotary body and bringing division into contact with each other. CONSTITUTION:A slit of a flat spring 2 is so formed in the shaped of a fine width having almost no gap that division are brought into contact with each other. A contact tip 1 is pushed against a shaft 3 by elasticity of the flat spring 2. When the shaft 3 rotates, the flat spring 2 vibrates complicatedly by friction generated between the contact tip 1 and the shaft 3. So long as parts divided by the slit 12 of the flat spring 2 don't vibrate with the same frequency and shape with each other, relative motion occurs between each of them. For that reason, vibration is damped by mutual frictional force, so that a screaming sound of the flat spring 2 can be prevented.

IPC: H01H13/04
Filed: 1994-10-24
Abstract: PURPOSE: To provide a push-button switch connector which prevents application of excessive forces to terminals and makes the surfaces of the terminals resistant to corrosion. CONSTITUTION: Two support legs 5a, 5b are provided integrally at the front wall part 13a of the mounting frame 13 of a push-button switch 3. The ends of the support legs 5a, 5b are held in place on the mount 1a of a conveying tape 1 by use of adhesive paper 1b.
