Title: Channel selection device in tuner
Inventor: TAKEGAWA TOMOHIRO
IPC: H03J5/02
Filed: 1988-06-03
Abstract: PURPOSE:To simplify and speed up a channel selecting operation by automatically channel-selecting a frequency until it is tuned in accordance with an offset value. CONSTITUTION:If the listener of a travelling vehicle inputs a part of the frequency by a lead 14 and operates a channel selecting start lead when he does not know an accurate broadcasting frequency, a control circuit 13 judges zero in the offset value, calls frequency-dividing number corresponding to the set frequency from a ROM memory 16, and outputs it to a programmable frequency divider 8. When there is an inputted broadcasting station by the inputted frequency-dividing number, a tuned signal is outputted from a detection circuit 5, and the control circuit 13 receives the tuned broadcasting station if the tuned signal is present. When the tuned signal is not outputted on the other hand, tuning and a reception action are executed by shifting the offset value one by one until the tuned signal is outputted from the detection circuit 5.

Title: Method of solder bump plating
Inventor: OGAWA KENICHI
IPC: H05K3/34
Filed: 1988-06-02
Abstract: PURPOSE:To obtain a solder bump having a uniform composition by controlling a plating current density in a thick film resist hole. CONSTITUTION:A plating current density in a thick film resist hole is set at a value higher than a designed current density when the plating is started and the current is controlled so as to be gradually reduced and reach the designed current value when plating metal is deposited from the surface of the resist surface. Therefore, a phenomenon wherein an effective current density is declined when the plating flows are hardly exchanged in the thick film resist hole and the shortage of metal salt is produced and a part of the plating current does not contribute to the plating deposition and is used only for producing hydrogen can be avoided by increasing the current value. With this constitution, a solder bump having a uniform composition can be obtained.

Title: Vibration-proof device for laser printer optical system
Inventor: OKAMOTO TOYOO
IPC: G03G15/043
Filed: 1987-05-31
Abstract: PURPOSE:To isolate the vibration of an optical system without increasing the thickness of a frame body nor putting ribs in by fitting respective optical components of a laser printer optical system to the frame body and supporting this frame body on the laser printer main body through a vibration-proof material. CONSTITUTION:An optical component is fitted to the one frame body 12, which is supported on a printer main body frame 14 by using vibration-proof rubber, springs, or other vibration-proof materials (damper) 13. This support structure makes it hard to transmit various vibrations of the laser printer to the frame body, and even if vibrations are applied, an optical system is united, so the vibrations never affect the performance of the optical system greatly. Further, the frame body need not be reinforced by thick ribs, so the lightweight, inexpensive optical system for the laser printer is realized.

Title: Active filter
Inventor: TAKANO MUTSUMI
IPC: H02J3/01
Filed: 1998-05-19
Abstract: PROBLEM TO BE SOLVED: To provide an active filter(AF) which can easily cope with different ratios of current transformation for feeder current transformers of a power receiving facility. SOLUTION: A secondary-side common bus of a power receiving facility is connected to an active filter(AF) via a transformer. The AF combines feeder currents I1 -In from auxiliary current transformers AuxCT21 -CT2n installed at the secondary side of current transformers for detecting feeder currents and then extracts higher harmonic components of the combined current I to suppress higher harmonic waves. In this AF, the combination of the feeder currents is performed by by a multiplier circuits 221 -22n for multiplying the feeder currents I1 -In from the AuxCT21 -CT2n by the ratios K1 -Kn of current transformation of respective current transformers and thereby correcting the feeder currents and an adder circuit for adding up all the corrected feeder currents I1 -In .  Since ratios K1 -Kn of current transformation are set by setting devices 211 -21n , the AF can readily cope with different ratios of current transformation for the feeder current transformers.

Filed: 1998-05-19
Abstract: PROBLEM TO BE SOLVED: To provide a mobile radio communication system and a control method therefor with which the improved convenience of communication services can be provided while attaining simplification of the configuration. SOLUTION: A cordless telephone system compares information from a hand set peculiar information storage part 12c with an output from a hand set for outputting a supplied communication request through a comparative discrimination part 12d and discriminates whether the hand set is the original component of the system or not. Based on this discriminated result, the destination of connection is selected by a connection destination selecting part 12a and in the case of coincidence as a result of comparison, a connection control part 12b controls a connection and connects each part with any one of connected analog transmission lines 20, 22 and 24. Since only the hand set stored in the system is connected even when any hand set originates a call through an outside wire, illegal communication is prevented.  Further, since the analog transmission lines 20, 22 and 24 are exactly acquired by communication control due to an exchange station 12 and/or base station 14, the occupancy of lines in the connection is prevented.
