  • Patent number: 5950023
    Abstract: A camera capable of operating in a red-eye prevention mode. The camera has an electronic flash device which is activated by a drive circuit in synchronization with the exposure. The electronic flash device also serve as a pre-light-emission device capable of performing pre-light-emission for the purpose of preventing red-eye effect. When it is judged from the photographing condition that red-eye effect may occur, a controller activates the electronic flash device to effect a pre-light-emission for reducing the size of pupils of eyes of a person to be photographed, before the main flashing which is executed in synchronization with the exposure.

  • Patent number: 5916026
    Abstract: An elastic universal joint is constructed to prevent an interference between a front end surface of a shaft and a front edge of a second arm of a second yoke irrespective of an intersecting angle between two first and second yokes without increasing a size of the first yoke. For this purpose, a concave portion is formed in the front end surface of the shaft, and, in a state where the intersecting angle between the first and second yokes increases and a front edge of the second arm approaches closest to the front end surface thereof, this front edge enters the concave portion. A distance between a cross shaft and the front end surface is reduced corresponding to a depth of the concave portion, and the first yoke is downsized with a smaller weight, correspondingly.

  • Patent number: 5892572
    Abstract: A projection exposure apparatus has an exposure processing section for projecting and exposing an image of a pattern of a reticle on a photosensitive substrate, an environmental chamber for covering the exposure processing section and a fan unit for supplying a temperature-controlled gas to the environmental chamber. Exposure to the photosensitive substrate is carried out in a temperature-controlled atmosphere. The pressure of the gas in the environmental chamber is monitored by a pressure sensor. When the pressure is changed, the mixture ratio of the gas supplied to the environmental chamber is changed to keep the refractive index of the gas in the chamber constant thereby to prevent imaging characteristics of the projected image from deteriorating.

  • Patent number: 5891050
    Abstract: The invention relates to a method and a device for determining and monitoring the degree of narcosis in a subject. The determination proceeds as follows. Auditory stimuli are generated by means of a stimulus generator (1). Response signals which signalize the response of the auditory chain to said stimuli are picked up by means of electrodes (4) on the patient's head (3). The response signals are converted by a digitizer into digital response signals. For each digital response signal, an implementation is generated by selecting a portion of the digital response signal. A signal processing means (7) is arranged, by means of which a first and a second mean signal of implementations is formed and by means of which the second mean signal is adapted to the first mean signal for forming an adapted mean signal. Finally, a waveform estimate of the adapted mean signal is formed with the aid of the signal processing means.

  • Patent number: 5888160
    Abstract: A load applied to the constituent member of a toroidal type continuously variable transmission is mitigated to thereby improve the durability thereof. During low speed running, a clutch for low speed is connected and a clutch for high speed and a clutch for backward movement are disconnected. During high speed running, the clutch for high speed is connected and the clutch for low speed and the clutch for backward movement are disconnected. During the high speed running, a torque is applied to the output side disc of the toroidal type continuously variable transmission. This torque becomes smaller as the transmission ratio as a whole is displaced to the high speed side. Correspondingly thereto, the load applied to the constituent member of the toroidal type continuously variable transmission can be mitigated.

  • Patent number: 5872735
    Abstract: An electrically alterable, non-volatile memory cell has more than 2 memory states that can be programmed selectively. Programming of the cell is conducted by applying a plurality of programming signals having different characteristics to the cell. The programming signals include at least a first programming signal which programs the cell by a first increment and a subsequent programming signal which programs the cell by a second increment smaller than the first increment. As the cell is being programmed to a selected state, its programming status is verified independently of reference values bounding the memory states. For this purpose, a signal indicative of the programming status (e.g., the cell's bit line signal) is compared with a reference signal corresponding to the selected state but having a value different from the reference value or values bounding the selected state. The programming operation can thus be controlled without actually reading the memory state of the cell.
