Title: Bright galvanized parts and bright galvanizing method for electric and electronic parts without generating whiskers
Inventor: SARUWATARI AKIRA
IPC: H01B1/02
Filed: 1995-06-16
Abstract: PURPOSE: To prevent the formation of zinc whiskers in a plating layer by using zinc cyanide mixed with a brightening agent and directly subjecting the surfaces of metallic parts to galvanizing at the time of forming bright galvanized films on these surfaces. CONSTITUTION: A plating bath is prepd. by incorporating 70 to 160g/L caustic soda and 50 to 110g/L sodium cyanide and adding the brightening agent thereto. Electroplating of zinc is executed by using such bath. The surfaces of the metallic members to be plated are previously subjected to plating of strike copper at a film thickness of 0.1 to 2μm and thereafter, the galvanized films of a film thickness 2 to 20μm are formed by using the zinc cyanide liquid in order to impart an electromagnetic shielding effect thereto. The plating bath consisting of the caustic soda and sodium cyanide of the high concn. sufficiently removes the smut (metal oxide) on the surfaces of the metallic members to be plated, thereby homogenizing the plating layers and completely suppressing the formation of the zinc whiskers.

Title: Recovering method for plating liquid
Inventor: SHIMODA HIROSHI
IPC: C25D21/20
Filed: 1989-07-04
Abstract: PURPOSE:To easily recover the carried-out plating liquid by introducing high- concn. fundamental liquid into a recovery device as plating liquid before recovered dilute plating liquid is introduced into the recovery device and thereafter introducing this recovered dilute plating liquid thereinto and performing concentration to recover the plating liquid. CONSTITUTION:Plating liquid 3 which is stuck on a body to be treated and carried out from a plating treatment tank 5 is mixed and diluted with the recovered washing water 10. This recovered dilute plating liquid 4 is introduced into a recovery device 19. Vapor generated in the case of performing concentration is recovered as the washing water 10. Concentrate is returned to the plating treatment tank 5 as the recovered return plating liquid 13 to recover the plating liquid. Therein high-concn. fundamental liquid 14 described hereunder is introduced into the recovery device 9 as plating liquid. Even when this fundamental liquid 14 is concentrated before the recovered dilute plating liquid 4 is introduced into the recovery device 9, the component of plating liquid is not decomposed. Thereafter the recovered dilute plating liquid 4 is introduced and concentration is performed to recover the plating liquid. Thereby the need for drainage treatment is eliminated because the diluted plating liquid is recovered and reutilized.

Title: Steering device for vehicle equipped with bevel gear
Inventor: KOMIYA KATSUYUKI
IPC: B62D1/16
Filed: 1986-07-23
Abstract: PURPOSE:To reduce vibration being transmitted to a steering wheel upon occurrence of shimmy, by controlling a drive means such that the force for pushing a friction block is increased when a resonant condition of the steering wheel is detected. CONSTITUTION:When shimmy is detected by an acceleration sensor 23 for detecting the lateral acceleration of a tierod of a rack shaft, the duty ratio of drive pulse is increased by a control unit 22 on the basis of a detected signal. Consequently, the quantity of relief oil being fed from a relief oil path 20 is reduced and the pressure of oil in an oil chamber 16 and a head side oil chamber 15 is increased to a predetermined level. As a result, a friction block 13 is pressed with a considerably large force against an endface 10a of an input shaft bevel gear 10, thereby an input shaft 4 is restricted by a frictional force functioning between the friction block 13 and the endface 10a even if a resonant vibration is transmitted from a front wheel to an output shaft 4 thus preventing transmission of vibration to a steering shaft 3.

Title: Distribution area setting method in information distribution service
Inventor: MORITA HIDEO
IPC: H04W68/08
Filed: 1998-06-19
Abstract: PROBLEM TO BE SOLVED: To properly reduce quantity of information distributed in the information distribution service. SOLUTION: Distribution information in a data server 2 is distributed to a distribution area A1 with the 1st priority. In the case that a concerned mobile set 7 in a receptible state is resident in the 1st distribution area A1, the mobile set sends a transmittal acknowledgement signal through this distribution to the data server 2. In the case that the transmittal acknowledgement signal is not returned from all mobile sets, distribution information is distributed to a distribution area A2 with 2nd priority, and the similar processing is conducted by lowering the priority untill the transmittal acknowlegement signal is confirmed from all the mobile sets.

Title: Heat exchanger utilizing assembly of tube sheets
Inventor: KASAHARA KEISUKE
IPC: F24S90/00
Filed: 1979-12-28
Abstract: PURPOSE: To provide the titled heat exchanger which is free from adhesion of dust when it is used at the roof of a green house or the like and has a high thermal efficiency by a method wherein soft plastic tubes are provided at proper intervals on the lower side of, and integrally with, a soft plastic sheet made of the same material as that of the tubes and a heat-absorbing medium is circulated in the tubes.  
     CONSTITUTION: When the assembly tube sheet 4 is applied to the roof of the green house 1 and water is circulated through the tubes 4b, the circulating water is heated by solar heat during a fine weather. In this case, since the tubes 4b are on the lower side of the sheet 4 and are covered by the sheet 4a which has a lower thermal conductivity, no heat is lost outwards from the surfaces of the tubes 4b and the circulating water is heated sufficiently by a high air temperature at the space near the ceiling of the green house. The circulating water flows through a header 7 into heat- insulating pipes 10 buried underground so as to maintain the temperature of the ground. Accordingly, since the tubes 4b are provided on the lower side of the sheet 4, the outside surface of the sheet 4 is smooth, so that the deposition of dust and the like is prevented, the absorption of natural heat by the circulating water is improved and the coefficient of heat exchange is enhanced.

Abstract: PURPOSE: To prevent the occurrence of a DC offset for no signal even if the  pulse width of PWM.DSB waves is limited, by including an auxiliary signal,  which becomes a DC offset cancelling pulse, in PWM.DSB waves for no signal.  
     CONSTITUTION: The output from a PWM full-wave rectifying part 11 and the rectangular wave signal from a clock oscillating part 12 are operated for AND, and the output is applied to a PWM.DSB control signal generating part 13. The auxiliary signal from an auxiliary signal generating part 15 is inserted to the output from the control signal generating part 13 by an auxiliary signal  superposing part 14, and the output is applied to a transformer T 11 . The output induced in the secondary side of the trabsformer T 11  is switched by synchronizing switches S 1  and S 2  and is demodulated by synthesis. Since this demodulation output has the inserted auxiliary signal for cancelling DC offset, the integral output in a capacitor C 3  is in the no-output state where no DC components remains at all.
