Title: Structure of can crashed to reduce volume
Inventor: TSUCHIDA MASASHI
IPC: B65D1/14
Filed: 1991-11-05
Abstract: PURPOSE:To realize an easy crashing by hand and also a prevention of too complete a breaking to be reused, by a method wherein thread folding lines and valley folding lines are provided to cross a providing direction of a recessed and protruding part in which reducing lines and reducing surfaces for reducing can volume are provided. CONSTITUTION:In a side 1 of a hollow can made of metal material such as aluminum or iron, a recessed and protruding part 4 is formed in which a given number of reducing lines 5 and reducing surfaces 6 for reducing can volume are provided. In another direction to cross the direction of the recessed and protruding part 4, other recessed and protruding parts 3 and 3' comprising thread lines 7 and valley folding lines are provided. By forming the vertical recessed and protruding parts 3 and 3' crossingly, a zigzag structure makes the can strong enough against force from a can gripping direction and also strong enough against force in the vertical direction not be to crashed. Contrarily, if the recessed and protruding part 3 such as the folding line on the can side surface 1 is pushed only by fingers, the folding line on the recessed and protruding part 3 disappears with a characteristic sound of the metal, and at once, it becomes easy to crash the can in the vertical direction and the can volume can be reduced easily.

IPC: G01B11/00
Filed: 1994-12-21
Abstract: PURPOSE: To stably hold a measurement head on a base at a narrow gap by an air cushion by producing a flowing out aperture part from a gas permeable plate having a finely porous structure. CONSTITUTION: A flowing out aperture part 6 for compressed air is produced using a gas permeable plate 14 having a finely porous structure.

Title: Method for replacing heat storage unit while maintaining temperature distribution of heat storage layer of regenerative burner and apparatus therefor
Inventor: SHIGETA EIJI
IPC: F23L15/02
Filed: 1995-12-07
Abstract: PROBLEM TO BE SOLVED: To make it possible to replace heat storage unit while maintaining the temperature distribution of the heat storage layer of a generative burner by discharging a small amount of the unit from a heat storage chamber at each time of lapse of time, introducing the small amount and replacing the unit while eliminating the collapse of the temperature distribution of the layer. SOLUTION: A heat storage unit 7 for constituting a heat storage layer 8 is discharged by each small amount from a heat storage chamber 1 at each time of lapse of time, the small amount is introduced, and the unit 7 is replaced while eliminating the collapse of the temperature distribution of the layer 8. For example, when a discharge valve 4 is opened for about 5 sec, the unit 7 is dropped for the time, and only the dropped amount is introduced from a heat storage chamber supplementing chamber 5 via a heat storage unit supply unit 6. When the valve 4 is formed in a conical shape, the discharge is smoothened. In this case, since the constitution of the storage chamber lower part 2 is formed in an inverted conical state, the entirety is lowered without irregularity, and the temperature distribution can be maintained.  The valve 4 may be switched, for example, at each 30min irrespective of the heating or cooling of the unit 7 in the case of heat storage burning.

Title: Scanning electron microscope
Inventor: YAMAMOTO YOICHI
IPC: H01J37/28
Filed: 1993-12-20
Abstract: PURPOSE:To improve efficiency of detecting a secondary electron, also to prevent the detecting efficiency from changing due to changing excitation of an objective lens, and further to prevent astigmatism from being generated of a primary electron beam. CONSTITUTION:A secondary electron guided to an upper part of an objective lens 1 flies up high in all directions relating to an axis of an electron beam EB. However, the secondary electron toward all the directions collides against an internal surface of a cylindrical member 5, to charge its surface. As a result, a negative potential is generated in each internal surface of the cylindrical member 5, and consequently the secondary electrons, guided to the upper part of the objective lens 1 to fly up high in all directions, are locked in the inside the cylindrical member 5 by this negative potential, and rise up along an electron beam optical axis, and efficiently detected by an MCP(multichannel plate) 6.

Title: Constant voltage power supply
Inventor: TOKUNAGA SATOSHI
IPC: G05F1/10
Filed: 1990-11-27
Abstract: PURPOSE:To suppress drop of AC output voltage from a constant voltage power supply upon increase of load by disposing means for detecting the average value of output current on the output of a transformer and correcting a sinusoidal reference signal based on the output from the average output current detecting means. CONSTITUTION:When a load increases, inverter current increases by an amount corresponding to the increase of load current and thereby output from an inverter current error amplifier 11 for shifted excitation control increases thus lowering the input to the error amplifier 10. On the other hand, output from an output current rectifier 16 increases in proportion to a load current and added to a voltage reference 13. Consequently, input to a sine wave reference generator 12 increases thus increasing the amplitude of output sine wave. In other words, output voltage drop of a constant voltage power supply can be suppressed by regulating the output of the output current rectifier 16 by an amount corresponding to the increase of output from the inverter current error amplifier 11 for shifted excitation control thereby maintaining a constant output level.

Title: Protecting box device for temperature and humidity measuring sensor
Inventor: FUJINO HIROSHI
IPC: G01K1/08
Filed: 1997-11-21
Abstract: PROBLEM TO BE SOLVED: To precisely measure the temperature or humidity of the outside air by housing a temperature and humidity measuring sensor within an inner box having an outside air introducing fan, and covering the inner box with an outer box having an outside air introducing port. SOLUTION: A temperature and humidity measuring sensor 7 inserted through the insert port 8 of a mounting plate 3 is housed within an inner box 4. The measuring sensor 7 is connected to a personal computer set in a room. When an intake fan 22 is driven, the outside air is carried into an outer box 5 through an outside air introducing port by the sucking force of the fan 22. This outside air is passed through an outside air inflow passage and carried into the inner box 4 having the temperature and humidity measuring sensor 7 housed therein through an outside air inflow port 20, and discharged to the outside through an outside air discharge port 37. Thus, it can be prevented that the outside air is stayed within the box, or the discharged outside air is carried again into the box, and new outside air is regularly sent to the temperature and humidity measuring sensor 7.  Therefore, the measurement by the temperature and humidity measuring sensor 7 can be regularly performed with high precision, and a highly reliable measurement result can be provided.
