Filed: 1998-01-28
Abstract: PROBLEM TO BE SOLVED: To provide a camera miniaturized in the sliding direction of a slide cover. SOLUTION: A strobe light emitting part 8 is used to switch the on/off of the power source of a camera main body. When the slide cover is slid to a photographing position where a lens barrel is exposed, the part 8 is energized by a torsion spring 46 and turned to an exposing position where its light emitting surface 8a faces to a subject. In such a case, an energizing lever 45 attached to the end of a turning shaft 32 turning together with the part 8 presses the movable switch armature 48b of a power source switch 48 and brings it into contact with a fixed switch armature 48a so as to turn on the power source of the camera main body. Since a gap for actuating a power source switch between the slide cover and the lens barrel is not required, the camera is miniaturized in the sliding direction of the slide cover.

Title: Semiconductor device
Inventor: NAGAI HIROAKI
IPC: H01L29/78
Filed: 1992-01-31
Abstract: PURPOSE:To decrease a leak current, and also to reduce the variation of the threshold voltage of a MOS by a method wherein the gate length of the gate electrode on the boundary region between an active region and an inactive region is formed longer than the gate length of the gate electrode length of the active region. CONSTITUTION:In the boundary region between the end part of an interelement isolation insulating film 6, i.e., an active region and a non-active region, the gate length of a gate electrode 9 is longer than the gate length of the gate electrode 9 on the active region. Consequently, as the distance between two n-type semiconductor 10 becomes larger, the length of leak path due to crystal defect becomes long. Accordingly, the leak current applied through the leak path is decreased. Also, as the distance between the two n-type semiconductor regions becomes longer, an inverted layer is hardly formed between the n-type semiconductor regions, and the variation of the threshold voltage of a MISFETQ can be lessened. As a result, the performance characteristics of the semiconductor device can be improved.

Filed: 1999-01-26
Abstract: PROBLEM TO BE SOLVED: To eliminate window contamination and measurement errors even when a piping temperature decreases by substituting a fluid to be measured in the piping including a window with a fluid which does not contaminate the window in a non measurement state. SOLUTION: On the measurement, three-way valves MV1 and BV6 are opened while the others are closed, so that a heavy oil is sent from a sample inlet 23 to a recovery tank 24 through the valve MV1 to an analyzer body 12 to the valve BV6. In a cleaning mode after the measurement, a kerosene in a kerosene tank 20 is sent to the tank 24 through a flowmeter 15 to a three-way valve MV3, to a stop valve MV5, to the valve MV1 and to the analyzer body 12. A predetermined time later, the air is introduced from an air source 22 through the three-way valve MV4 into a piping and sent in the same route as the kerosene. As a result, the air enters the piping filled with the kerosene and bubbles, thereby removing a deposit (pollutant) adhering in the piping including a window. The kerosene and air are repeatedly introduced until the deposit is detached, thereby cleaning the piping.  Thereafter, the BV6 and MV5 are closed, thereby shutting the kerosene in the piping including the window of the analyzer body 12. The window is accordingly prevented from being polluted even when a temperature decreases in a non measurement state.
