Filed: 1987-03-30
Abstract: PURPOSE:To adsorb and remove organic additives deteriorated in use and to regenerate a plating liquid by subjecting the plating liquid of Pd-Ni alloy contg. the organic additives such as a brightener and a pit preventive to oxidation treatment and thereafter treating it with activated carbon. CONSTITUTION:Plating treatment is carried out by using the plating liquid pred. by adding an organic additive of both sulfonate used as a brightener of a plated film of Pd-Ni alloy and phosphoric ester used as a pit preventive to the plating liquid of Pd-Ni alloy which contains Pd ion and Ni ion and is regulated to 8-9 pH. This organic additive is liable to be deteriorated during plating treatment and therefore the quality of the film surface of the plated film of Pd-Ni alloy is deteriorated. In this case, after subjecting the plating liquid to oxidation treatment by adding an oxidizing agent such as hydrogen peroxide, perchloric acid and potassium permanganate or O2 thereinto, the organic additive contg. deteriorated materials is adsorbed with activated carbon. After filtering and removing activated carbon, the plating liquid of Pd-Ni alloy is regenerated by newly adding the brightener and the pit preventive.

Title: Mobile object detector
Inventor: TABUSE EITOKU
IPC: G08B25/04
Filed: 1995-03-31
Abstract: PURPOSE: To provide the mobile object detector whose power consumption is economized. CONSTITUTION: When a person gets close to a mobile object detector 2, this is detected by an approach detection sensor 6, and a detecting signal is outputted. While receiving this detecting signal, a switching means 8 closes switches SW1 and SW2 and supplies a power source to a reception part 10 and a transmission part 12 as a processing part. Thus, the reception part 10 is operated and an ID code from a transmitter 4 provided on the side of person is received. The reception part 10 sends this ID code to a warning means 14. The warning means 14 issues an alarm. Besides, the reception part 10 sends the received ID code to the transmission part 12 as well. The transmission part 12 transmits this ID code to a main controller 20. At the main controller 20, it is displayed based on the received ID code who approaches a door.  No power is supplied to the reception part 10 and the transmission part 12 until the approach detection sensor 6 detects any person. Therefore, power consumption at the mobile object detector 2 can be suppressed and even when this device is driven by a battery, it can be operated for a long time.

Title: Semiconductor device
Inventor: IIDA NORIHIKO
IPC: H03L7/08
Filed: 1990-03-22
Abstract: PURPOSE:To eliminate a problem of the level conversion by using a power supply different from those of other circuits to a phase comparator of a PLL circuit formed on a semiconductor substrate. CONSTITUTION:The component parts including a charge pump 8 are formed on a single chip, and the voltage is supplied to a phase comparator 5 and the pump 8 via power terminal 21. Meanwhile the voltage is supplied to a reference divider 1 and a programmable counter 2 via a power terminal 20. Thus at least the divider 1 and the counter 2 are actuated with the voltage of a low level in a PLL circuit formed on a semiconductor substrate. As a result, the current consumption is reduced and furthermore a problem of the level conversion can be eliminated since the different power source supplies power to the comparator 5 and the subsequent component parts.

IPC: B23K1/00
Filed: 1988-03-29
Abstract: PURPOSE:To perform resistance diffusion joining without deteriorating strength of a joining part by inserting low melting point metal between materials to be joined and pressing it between electrodes in opposition and applying a current between both electrodes to melt and join. CONSTITUTION:The set pressure is applied to the electrode 1a by a pressure device 4 and brazing filler metal 3 such as Ni amorphous inserted between the materials 2a and 2b to be joined is pressed. The current is then applied via the brazing filler metal 3 between the electrodes 1a and 1b to melt the brazing filler metal 3 and the materials 2a and 2b to be joined are subjected to diffusion welding. At this time, as the displacement of the electrode 1a increases, the displacement of a reference plate 10 also increases but the pressure device 4 can be operated by the set pressure by controlling an inflection point where the displacement increases by a displacement gage 11 by a controller 9. By this method, the resistance diffusion with the little quantity of a deformation can be performed without deteriorating the strength of the joining part.

Abstract: PURPOSE:To avoid deterioration in demodulation even when line fluctuation exists by providing plural sets each comprising a correlation computing element, a known signal ROM and an impulse response calculator to acquire plural impulse response signals with a time difference even when the length of a known signal to be inserted in a transmission data is short. CONSTITUTION:Correlation computing elements 20-2M-1 are used to take correlation between known signal ROM data 72-7P-6 (P=M+7) and a reception signal 1. The data 72-7P-5 differ from the correlation computing elements 20-2M-1 by a deviation of a symbol each, then the data are processed as shown in the following. Let the autocorrelation of a known signal in general be Rs(X) (Where X is an integer), the correlation with respect to a reception signal (known signal) be Rbs(X), and an impulse response of a line be h(X), then since (X=0-(N-1)), they are expressed in equation, and it is possible to obtain the h(X) by solving the equation. Thus, impulse response sets deviated to each other are acquired by using known signal ROM data at a shift by one symbol each for the calculation.
