Title: Camera suitable for photographing with one hand
Inventor: NOZAWA TOSHIHIDE
IPC: G03B17/02
Filed: 1994-04-01
Abstract: PURPOSE:To prevent operation mistakes such as camera shake in photographing with one hand by constituting a camera so that a line segment connecting a photographic switch and a finder optical system is almost parallel to the direction of film movement. CONSTITUTION:In the finder optical system, a variable lens constituted of four reflection planes R1-R4 and positive lense groups L1 and L2 capable of being moved on an optical axis by a motor 10 is arranged between an incident plane 3 and a light emission plane 12. On the left side of the camera 1, a recessed part 1 is formed so that a photographer can easily hook his thumb round the camera, and a shutter switch 13 is provided thereon. The line segment connecting the photographic switch 13 and a part of the finder optical system is arranged almost parallel to the direction of the movement of the film 5. Thus, at the time of photographing, the shutter switch 13 for photographing can accurately be operated by holding the camera 1 in one of photographer's hands with the back of the hand facing a subject and by abutting the back of the camera on his forehead.

IPC: B22D27/04
Filed: 1981-04-28
Abstract: PURPOSE:To cast a hollow billet of small fluctuations in inside diameter by installing a refractory core concentrically on the inner side of a water cooled mold, and controlling the temp. of the core so as to be kept constant during casting. CONSTITUTION:A core to be installed concentrically on the inner side of a water cooled mold is made into a circular truncated cone shape having a circular columnar upper part B and a tapered lower part A. The angle theta of the taper is preferably about 5-30 deg.. The set value of the ouside wall temp. of the core is stored in a temp. detection controller 26 and is compared with the actually measured value of a temp. detection end 25. If the actually measured value is higher than the permissible upper limit value of the set value, the output signal of the controller 26 is put into a flow rate controlling valve 27 for coolant to increase the flow rate of the coolant to be supplied into the inlet 23 of a coolant flow pipe 22. Conversely, when the actually measured value is lower than the permissible lower limit of the set value, it is so controlled as to decrease the flow rate of the coolant.

Title: Indoor stop valve for cold district
Inventor: KOIZUMI AKIO
IPC: E03B9/02
Filed: 1996-02-27
Abstract: PROBLEM TO BE SOLVED: To prevent breakage of a pipe due to freezing, by providing an auxiliary valve body made of a lightweight resin in the main valve body of a stop valve fitted to the branch point of an indoor pipe and removing the water in the pipe after the main valve has been closed to lessen the rest water therein. SOLUTION: A stop valve is provided at a branch point when water is supplied to the position with less use-frequency branched from a main water supply pipe for a kitchen or the like within a house. And when water is not used in a freezing season, the stop valve is closed and the water within the pipe is removed to prevent breakage of the pipe. When the rest water is removed, the handle 8 is turned and the packing 10 of the main valve body 6 is pressed on the valve seat 4 to cut off the inflow opening 2 and the outflow opening 3. When the water pressure of the inflow side is low, the light auxiliary valve body 16 is opened by the buoyancy to let water flow to the outflow side. In this state, water is discharged from the upstream side by manipulating a nonflozed water supply valve.  In this time, an air suction valve is set in the outflow side pipe to make it possible to discharge water without opening the faucet. In this way, the water in the pipe is reduced to prevent breakage of the pipe due to freezing.

Title: Position measuring method
Inventor: NONAKA MISAKO
IPC: G03F7/20
Filed: 1986-03-26
Abstract: PURPOSE:To measure the position with few errors by adding coloring material which is made of an optical absorbent with respect to measuring beams of light to a resist or selecting a wavelength of the measuring beams of light so the the resist itself is made of the absorbent. CONSTITUTION:With respect to the resist 15 formed on a silicon wafer 4 as a substrate, absorbent coloring material 14 of LED light, for example, the material containing 3% of aluminum-chloro-phthalocyanine is used. Since the incident light 13a on the inside of the resist 15 is attenuated when the measuring beams of light 13 are irradiated on the coloring material 14, the reflected light 13b reflected on the resist surface is detected with a photodetecting element without receiving the interference of the incident light 13a. Accordingly, the measuring error can be reduced. Moreover, a reflection from the resist 15 and the substrate interface can be efficiently prevented by setting the measuring beams of light to the wavelength 450-200nm without letting the coloring material enter into the resist 15 and attenuating the measuring beams of light in the resist 15.
