    Abstract: A micro-displacement measuring apparatus using a semiconductor laser, comprises a compound resonator system containing the semiconductor laser, and a light detector receiving the light from the semiconductor laser, and with the compound resonator system being constructed such that light from said laser irradiates an object to be measured and the reflected light therefrom returns to the semiconductor laser. The light detector detects and measures the number of fluctuations and the level of the optical output of the laser to determine the displacement of the object and of the direction of the displacement of the object, respectively.

    Abstract: An electric can opener comprises a can opener body, a can opening attachment and a juice squeezing attachment. The can opener body is provided with a drive shaft, a motor for rotating said drive shaft, a vertically holding portion and a horizontally holding portion. When the vertically holding portion is utilized to set the can opener body, the drive shaft assumes a horizontal condition. A horizontal rotating shaft provided on the can opening attachment can be brought into engagement with the drive shaft in the horizontal condition. Accordingly, the can opening attachment is utilized to cut out a lid of a can. On the other hand, when the horizontal holding portion is utilized to set the can opener body, the drive shaft assumes a vertical condition. A vertical rotating shaft provided on the juice squeezing attachment can be brought into engagement with the drive shaft in the vertical condition. Accordingly, the juice squeezing attachment can be utilized to squeeze fruit juice of citrus fruits.

    Abstract: A method of thermoluminescent dosimetry employing infrared radiation heating of a dosimeter. An incandescent lamp is used for the source of infrared radiation. The dosimeter is provided with a infrared radiation absorbing layer connected thermally to a thermoluminescent material layer. The infrared radiation absorbing layer is irradiated with infrared radiation, so that thermoluminescent material is not directly irradiated. The lamp is initially powered whereby the dosimeter is heated by infrared radiation of such high intensity as to tend to cause a heat equilibrium in the dosimeter above the temperature where thermal radiation is generated from the dosimeter. Then the power supplied to the lamp is cut or decreased, so that the dosimeter is heated by the afterglow of the lamp. Therefore the rate of temperature rise of the dosimeter becomes quite slow in the latter half of heating process, whereby the temperature of dosimeter easily falls into the required range.

    Abstract: Wireless noise is detected within a time period specifically held after a data packet is wirelessly communicated, where no data is purposefully wirelessly communicated during this time period. The time period may be an inter-frame space (IFS) period within which no data is to be wirelessly communicated, and that is a period waited for prior to accessing a wireless medium over which data is wirelessly communicated. One or more actions are performed to counteract the noise. The frequency at which a liquid crystal display is being driven may be decreased so that harmonics caused thereby that caused the noise are no longer within the wireless communication frequency range. An opposite-in-phase version of the noise may also or alternatively be combined with a signal when data is subsequently wirelessly received. The signal includes a data component and a noise component, the opposite-in-phase version of the noise canceling out the noise component.
