A wire clamping device which is used to clamp bonding wire in the wire bonding of electronic components comprising: a fixed arm; a movable arm that is positioned so that the end of the fixed arm faces the and of the movable arm with a suitable gap, the movable arm being capable of bending so that the end of the movable arm approaches the end of the fixed arm; and a piezoelectric element that is attached to the movable arm which bends the movable arm by mechanical deformation of the piezoelectric device in order to clamp wire between the end of the movable arm and the end of the fixed arm. A wire clamping method for clamping bonding wire comprising bending a movable arm toward a fixed arm during wire bonding of electronic components by means of mechanical deformation of a piezoelectric element, the deformation being generated by applying a voltage to the piezoelectric element.

A parallel operation histogramming device can handle parallel-input data from a plurality of processors to generate frequency data of a histogram. The processing time for generating frequency data of the histogram is independent of the distribution of histogram values in the input data. The device can also reduce the memory area used for accumulating frequency data of the histogram. The device includes a histogram counter circuit which has a plurality of counters equal in number to the number of histogram bins. The counters count in parallel the number of pieces of data for each type of the operation results from the plurality of processors. The counted values from each counter are accumulated to form the frequencies in a histogram.

A rear-wheel drive system includes motors for generating driving force to drive a vehicle, hydraulic brakes on power transmission lines between the motors and rear wheels switching a motors side and a wheels side to a connected state or a disconnected state, an ECU controlling the motors and the brakes and a one-way clutch in parallel with the hydraulic brakes on the transmission line configured to be engaged when a forward rotational power on the motors side is inputted into the wheels side and disengaged when a backward rotational power on the motors side is inputted into the wheels side and vice versa. The ECU causes the hydraulic brakes to be applied so as to put the motors side and the wheels side in the connected state when the forward rotational power on the motors side is inputted into the wheels side.

A liquid crystal display device includes: a vertical alignment liquid crystal layer; first and second substrates facing each other with the liquid crystal layer interposed; first and second electrodes arranged on the first and second substrates to face the liquid crystal layer; and at least one alignment film in contact with the liquid crystal layer. A pixel region includes a first liquid crystal domain in which liquid crystal molecules are tilted in a first direction around the center of a plane, and approximately at the middle of the thickness, of the liquid crystal layer responsive to a voltage applied. The first liquid crystal domain is close to at least a part of an edge of the first electrode. The part includes a first edge portion in which an azimuthal direction, perpendicular to the part and pointing toward the inside of the first electrode, defines an angle greater than 90 degrees to the first direction. The first or second substrate has an opaque member including a first opaque portion for selectively shielding at least a part of the first edge portion from incoming light.

A liquid crystal display device according to the present invention includes: a vertical alignment liquid crystal layer; first and second electrodes arranged on one surface of first and second substrates to face the liquid crystal layer; and first and second alignment films arranged on the first and second electrodes, respectively, in contact with the liquid crystal layer. The first alignment film has been subjected to an optical alignment treatment by obliquely irradiating a first alignment film material, having a photosensitive wavelength within the wavelength range of 250 nm to 380 nm, with light including the photosensitive wavelength. The device further includes: a metal layer arranged between the first alignment film and the first substrate; and a first resin layer arranged between the metal layer and the first alignment film. The first resin layer has an optical property that attenuates the intensity of light, which has been incident on the first resin layer and then reflected from the metal layer, to 60% or less at the photosensitive wavelength.

An in-vehicle recording/reproduction device (121) records in a recording device a program which the user starts watching, and reads and reproduces the data when watching is permitted, such as, for example, when a vehicle is stopped. The in-vehicle recording/reproduction device (121) transmits recording information about recording, such as a program, a time, and the like, to an in-home recording/reproduction device (303). The in-home recording/reproduction device (303) records the same program as that recorded by the in-vehicle recording/reproduction device (121) based on the recording information. The in-vehicle recording/reproduction device (121) transmits to the in-home recording/reproduction device (303) reproduction information indicating which scene was last reproduced in the in-vehicle recording/reproduction device (121). The in-home recording/reproduction device (303) performs reproduction based on the reproduction information. Thereby, it is possible to watch the rest of the program which was watched in the vehicle, at home without missing a scene.

A liquid crystal display device of the present invention includes a picture element electrode in a first substrate on the liquid crystal layer side in each picture element region, and a counter electrode in a second substrate opposing the picture element electrode via the liquid crystal layer. In each picture element region, the picture element electrode includes a solid portion including multiple unit solid portions; and the liquid crystal layer is in a vertical orientation state with no voltage, and upon voltage application, forms a liquid crystal domain taking a radially-inclined orientation in positional correspondence with each unit solid portion by an oblique electric field produced near the unit solid portion. The liquid crystal display device further includes a storage capacitor connected electrically in parallel to a liquid crystal capacitor, and the storage capacitor is at least partially located in an area with no solid portion of the first substrate.
