Alternatively, the stainless steel may further contain not more than 0.1% of Zr. The process for producing the steel includes producing a steel having a composition as described above by a consumable electrode remelting process, and then subjecting the steel to a solution treatment at a temperature of 1000 to 1150° C. and an aging treatment at a temperature of 400 to 550° C., thereby aging the stainless steel to a hardness of not lower than 59 HRC.

Abstract: An imaging apparatus of the invention comprises: an image pickup device for picking up object light; a mirror section for switching an optical path of the object light; a retaining member for retaining at least the mirror section; and a shake detection section for detecting a shake of the image pickup device, wherein the shake detection section is provided in a member separate from but indirectly connected to the retaining member via a predetermined connection section. The shake detection section is attached to the separate member connected indirectly to the retaining member that retains the mirror section and hence receives directly a vibration at the time of driving of the mirror section, with the intervention of the connection section. This avoids that the vibration caused by the driving of the mirror section is directly transmitted to the shake detection section. That is, the vibration is bypassed and damped along a route going through the connection section.

Abstract: A strong pressure and a strong shearing force are exerted to a mixture, constituted of two kinds or more of powder materials including a drug powder, while causing the mixture to pass between a press section (26) of a press head (24) and a receiving surface (25) of a cylindrical rotator (23), thereby combining the drug powder with the other powder material. For example, at least one of a drug and a biocompatible polymer is made into a nano particle whose average particle diameter is less than 1000 nm, and the nano particle is made into a composite in accordance with a dry mechanical particle combining method, so as to form a polymer nano composite particle. Thus, it is possible to produce a composite particle, which contains a drug under a stable condition, in a short time, and it is possible to remarkably improve its handling property without losing advantages of the nano particle.

Abstract: A digital camera comprises an electronic view finder (EVF) for electronically displaying an image of a subject and a movable monitor. The movable monitor is slidable along guide grooves and movable between a first position in which the EVF is covered with the movable monitor and a second position in which the EVF is not covered. By a sensor for position detection, when it is detected that the movable monitor is in the first position, no image is displayed on the EVF but an image is displayed on the movable monitor. When it is detected that the movable monitor is in the second position, no image is displayed on the movable monitor but an image is displayed on the EVF. Consequently, power can be saved, and when the movable monitor is in the first position, adhesion of dusts and dirt onto the display face of the EVF can be decreased.

When an event regarding reproduction, specifically, attachment of a lens cap, operation of a four-way switch or the like to reproduce an image or sound, or insertion of a memory card for reproduction is detected in the image capturing mode M1, the digital camera is automatically switched to the reproduction mode MD2. On the other hand, when an event regarding image capturing, specifically, operation of a pop-up flash, detection of contact of the eye to an eye cup, various settings regarding image capturing, insertion of a memory card for image capturing, or operation of image capturing with a self-timer, focusing, zoom, aperture, shutter button, recording, or display switching is detected in the reproduction mode MD2, the digital camera is automatically switched to the image capturing mode MD1.

Abstract: In a cartridge chamber of a camera is disposed a photoreflector to read a bar code formed on a disk attached to an end of a film spool. When a cartridge is loaded, the film spool is rotated more than one round in the direction to rewind the film. The photoreflector starts to read the bar code when supply of a driving force to rotate the spool is started. The leading part and the trailing part of the output signals of the photoreflector are compared in the reverse direction to find a point where signals corresponding to the constant rotation of the disk begin. The signals preceding the point are discarded and the initial position of the disk before it is rotated is determined based on the length of the signals truly representative of the bar code while the disk is rotating at the constant speed. Use condition of the film, unexposed, fully exposed, partly exposed or already developed, is judged from the initial position of the disk.

Abstract: A camera has an AE sensor 10 and a display member 32 disposed in the vicinity of the focusing screen 4, and a field frame switcher having a light interrupting wing capable of changing a field frame. The light-interrupting wing crosses and interrupts a predetermined luminous flux path used for obtaining information necessary for photographing while the field frame is changed. The light-interrupting wing is disposed close to the predetermined luminous flux path to reduce the space needed to house the structure.

Abstract: A field-of-view frame switching device has a rectangular fixed field-of-view frame and a plurality of light-shielding members for covering portions of the rectangular fixed field-of-view frame so as to vary the size of the actual field-of-view frame. The light-shielding members are composed of a first pair of oppositely arranged light-shielding members and a second pair of oppositely arranged light-shielding members. The field-of-view frame switching device also has a coupling member for coupling the light-shielding members together in such relation that, when the first pair of light-shielding members are positioned closer to each other to narrow the actual field-of-view frame, the second pair of light-shielding members are positioned wide apart from each other and that, when the first pair of light-shielding members are positioned wide apart from each other, the second pair of light-shielding members are positioned closer to each other to narrow the actual field-of-view frame.

Abstract: An apparatus capable of using a film cartridge in a manner that a lead portion of a film contained in the cartridge is fed out therefrom by the film thrusting, wherein a controller judges that an initial loading is not executed normally when a perforation is not detected although a fed film amount on an initial loading reaches a first predetermined amount, and stops a detector from detecting a perforation until the fed film amount reaches a second predetermined amount which is less than the first. Thus, a detector does not wrongly detect a notch on a film's lead portion as a perforation, and a leading frame is fed normally with a reliable judgment on an initial loading.

While the sensor is moved in a horizontal direction perpendicular to the optical axis of the sensor light, the distance to each of a plurality of measurement points arranged horizontally at regular intervals along a line that runs on said pile of the powdery or granular material so as to face the movement path of the sensor. This step is performed every time the sensor is moved vertically a predetermined distance at a time. In each session of the step, a point is extracted that is closest to the sensor, and a function describing a straight line approximating the curve through all of the thus extracted points is determined by the least-squares method.
