  • Electric tool power switch assembly providing convenient reversing operation and provided with sealed switch lever structure
    Patent number: 4847451
    Abstract: An electric power tool includes an electric motor. A switch assembly for this power tool includes a device for controlling the on/off operation of the motor, actuated to and fro along a first actuation line, and a device for controlling the forward/reverse operation of the motor, actuated to and fro along a second actuation line. The first and the second actuation line do not intersect one another. This confers good operability upon the switch and upon the power tool as a whole. More particularly, the first actuation line should be skew to the second actuation line, even more particularly substantially skew perpendicular to it; or, alternatively, the first actuation line may be substantially parallel to the second actuation line and somewhat displaced therefrom.

  • Plunger type fluid pressure switch
    Patent number: 4845322
    Abstract: A pressure receiving member which has a diaphragm held in a pressure receiving case is manufactured independently of a main sensor body member, which has a switch accommodated in a switch case. The pressure receiving member and the main sensor body member are then assembled to provide a pressure sensor.According to the present invention, since the pressure receiving portion and the main sensor body are manufactured individually, a diaphragm inversion movement test can be carried out individually of the testing of switch turning on and off, and hence only satisfactory pressure receiving portion and main sensor body which passed the respective tests will be utilized in the operation of assembling pressure sensors.

  • Electronic blood pressure meter
    Patent number: 4844084
    Abstract: In an electronic blood pressure meter for measuring blood pressure from a finger, there is provided a photoelectric sensor for detecting presence of a finger in the cuff. Thereby, it is made possible to positively avoid inflating the cuff without placing a finger therein and to prevent rupture and other damages to the cuff. In particular, since either a light emitting element or a light receiving element of the photoelectric sensor for detecting a finger is common to that of a photoelectric pulse wave detecting device incorporated in the cuff, the structure of the cuff is simplified and the manufacturing cost is reduced.

  • Method of manufacturing a stripe-shaped heterojunction laser with unique current confinement
    Patent number: 4839307
    Abstract: A semiconductor laser having an internal current restriction includes a (100) face-oriented p-type GaAs substrate treated to have a groove or difference in level having an (n11) A face (n=1-5) as an inclined surface. An AlGaAs: Si layer, an AlGaAs:Be cladding layer, an AlGaAs active layer, and an AlGaAs:Sn cladding layer are grown on the substrate in the order mentioned. Since the Si acts as an n-type material on the (100) face and as a p-type material on the (n11) face, the AlGaAs:Si layer becomes a p-type layer solely in the groove, and it is in this portion that a current path is formed. The laser can be fabricated by molecular-beam epitaxy applied in a single step.

  • Electronic cash register which records the time when the quantity of an item in stock falls to a predetermined number
    Patent number: 4833608
    Abstract: An electronic cash register (ECR) comprises a memory for storing the stocked quantity of a commodity item, the transaction time, and the sale amount with respect to each commodity item; a clock for producing a present time; and a keyboard for instructing the output of a report in connection with an end-of-day sales processing. The transaction time stored in the memory is updated every time a transaction is performed with respect to each commodity item. The ECR determines when the stocked quantity of each commodity item is reduced to a predetermined number, e.g., zero. The transaction time finally stored in the memory is printed out together with data representing an associated commodity item in response to instruction by the keyboard for each commodity item whose stocked quantity is detected as having been reduced to said predetermined number.

  • Credit transaction processing system
    Patent number: RE32985
    Abstract: A credit transaction processing system processes data related to a commodity entered into by using a card (17) owned by a customer and a recording card (16) owned by a store. First, merchant transaction data necessary for a credit sale stored in the recording medium (16), such as account number data for the store, data specifying a credit company, and data representing an upper limit of an amount to to be sold through a credit sale, are read by a card reader (5), and then, customer transaction data stored in the customer's recording card, such as account number data of the customer, data specifying a credit company and an identification number or code is read. If and when the customer enters his identification number by a ten-key (7), a central processing unit (12) determines whether the entered identification number coincides with the identification number read out of the customer's card.
