摘要:
A constant-current battery charger includes a power supply for supplying a charge current to a secondary cell, and a current monitor for monitoring a charge current being supplied to the cell. A controller is included for varying the charge current in accordance with the monitored charge current. The controller calculates a current difference between a predetermined target current and the instant charge current, and generates a demand of varying the charge current at a first charge rate when the current difference is out of a predetermined range, and varying the charge current at a second charge rate when the current difference is within the predetermined range. The controller generates the demand repeatedly at regular or varying intervals for varying the charge current. The first charge rate is set to be higher than the second charge rate in order to make a rapid charging until it comes close to the target current. Since the current difference between the instant charge current and the target current is relied upon to switch the charge rate between the first and second charge rates, the switching can be made at an exact timing truly indicative of the condition of the battery, which enables a rapid charging, yet assuring to complete the charging successfully.

A power tool system with enhanced antitheft capability has a hand-held power tool and a wearable piece worn by the user. The wearable piece incorporates a certification unit which stores an identification code specifying the power tool and transmits the identification code to an authenticator incorporated in the power tool. The authenticator reads the identification code from the certification unit and to provide an authentication signal when the identification code is authenticated to be eligible for a privileged use of the power tool. The power tool is enabled only in response to the authentication signal, and otherwise disabled for avoiding unauthorized use. A communication is established between the certification unit and the authenticator for transmission of the identification code, while the user holds the power tool with the wearable piece carried on.

A substrate processing system which sprays exposure process gas onto a substrate disposed within a chamber. The substrate processing system is used, for example, for performing an exposure process of an organic film formed on a substrate in a gas atmosphere obtained by vaporizing an organic solvent solution for dissolving and reflowing an organic film. The substrate processing system comprises: the chamber having at least one gas inlet and at least one gas outlets; a gas introducing means which introduces the exposure process gas into the chamber via the gas inlet; and a gas distributing means. The gas distributing means separates an inner space of the chamber into a first space into which the exposure process gas is introduced via the gas inlet and a second space in which the substrate is disposed. The gas distributing means has a plurality of openings via which the first space and the second space communicate with each other and introduces the exposure process gas introduced into the first space into the second space via the openings.

A high-speed current switch circuit of this invention has an n-type MOS transistor Q11 which switches and outputs a current, and a control circuit 11 which performs switching control of the MOS transistor Q11. In the control circuit 11, a source follower is formed by an N-type MOS transistor Q12 and a constant current source I2 which is a load on this transistor. A switch SW11 is connected to the MOS transistor Q12 to perform switching control of a current flowing through the MOS transistor Q12. The control circuit 11 includes a switch SW12 capable of grounding the gate of the MOS transistor 11. The source of the MOS transistor Q12 is connected to the gate of the MOS transistor Q11. Thus, even if a large current is caused to flow through the output transistor, the output transistor can be made to operate for switching at a high speed.

Disclosed is a method of forming an electrically conductive circuit comprising the steps of: preparing a transferring paper in which an assembly of electrically conductive foil carrying a predetermined pattern and an insulating layer containing glass frit and an overcoat layer consisting of a resin film having good burning property are provided on a transferring paper covered with a paste layer; removing an integral structure of the conductive foil, the insulating layer, and the overcoat layer from the transferring paper; transferring the removed integral structure onto a substrate; and burning the substrate with the integral structure set thereon at a temperature where the glass is soften. According to this method, it is possible to eliminate transformation or damage of a conductive foil where a conductive foil is singly disposed on a substrate.

摘要:
A toy has a body in the shape of a characterized animal. At least one of the extremities, preferably the head, is attached to a movable member which moves between a retracted position wherein the majority of the member is located inside the body to an extended position wherein the greatest portion of the member is located external of the body. The toy includes a mechanism which will move the member from its extended position to its retracted position upon activation of a mechanism at least a portion of which is exposed outside the body for manipulation by the operator. The member in going from its extended position to its retracted position reaches its retracted position and then automatically reverses itself until it is once again extended.
