Title: Bulge working device
Inventor: YOSHITOMI YUUJI
IPC: B21D26/041
Filed: 1981-06-12
Abstract: PURPOSE:To bulge-mold a bulging part of a desired shape on a part of a pipe with high dimension accuracy, by detecting a pressurized liquid added into a material pipe, and controlling the liquid pressure and an axial load added onto the material pipe end by use of a cam and a pressure controlling valve. CONSTITUTION:In a bulge-working device of a pipe material, which uses a split metallic mold, at first, a direction changeover valve 60 is energized, a pressurized liquid is fed into a material pipe 1 through a high pressurized liquid  leading-in hole 7, and bulge-molding is started. At the same time, the pressurized liquid is fed to a pressure chamber 54 of a cylinder 53, and a piston rod  49 and a cam rod 47 are moved in the direction (c). As a result, a cam 46 is moved, and in accordance with its inclined surface 46a, a guide bar 42 of a pressure control valve 39 is moved in the direction (e), and a pressure control valve  40 is pressed against a pressurized oil hole 39a. Accordingly, the pressurized oil  which has been flowing to an oil pressure tank 45 is reduced, oil pressure added  to the cylinder 53 is raised, and an axial load added to the material pipe 1 is  increased. The bulge-working is performed by continuously excecuting this  operation and controlling the axial load and the liquid pressure.

Title: Rice cooker
Inventor: ISHII NORIO
IPC: A47J27/00
Filed: 1993-04-16
Abstract: PURPOSE:To make the speed of heat conduction steady, to advance the time to end boiling and to reduce uneven cooking result and scorching by forming the inner pot in the approximate hemispheric shape with a concaved flat face provided at the center of its bottom. CONSTITUTION:The bottom of the inner pot 10 forms at its center a circular concaved flat face 10a caving inwards slightly. Here, the corner part of the inner pot 10 forms an approximate hemisphere of the curved surface in long radius, and accordingly, even when the quantity of rice to be cooked is small, the thickness of layer Dn of rice (ri) is maintained high. As a result, the difference of distances from the bottom of pot being small, the transmission of heat to the central part is made fast. The heat is given from the outside of inner pot 10 and transmitted to the central part. Here, the temperature sensor 16 touches the concaved flat face 10a at the center of the inner pot 10 closely under pressure of spring of the sensor spring 17 and detects the exact cooking temperature, preventing the lowering of cooking accuracy. Further, the height of coil (nn) becomes high, leading to the ideal cooking temperature characteristics.

Title: Photosensitive sheet, lenticular screen using same and its production
Inventor: AIZAWA HIROTAKA
IPC: G03B21/62
Filed: 1998-04-02
Abstract: PROBLEM TO BE SOLVED: To obtain a high-contrast clear lenticular screen for a transmission type screen free from drop-out and chipping by using a black or white temporary support. SOLUTION: The base material of a temporary support 22 is colored black with a pigment such as carbon black or iron black, or white with a colorant such as titanium dioxide or talc. When a lenticular screen is produced, the setting part 21(b) of a photosetting photosensitive layer 21 supported by the temporary support 22 is set and the support 22 is peeled. A transfer sheet 30 with a black colored layer 31 formed on the base material 32 is then put on the entire surface of the photosetting photosensitive layer 21 so that the layers 31 and 21 confront each other. The black colored layer 31 is stuck only to the unset part 21(a) and the layer 31 on the set part 21(b) is peeled to form a black light shielding layer. Since the temporary support 22 is colored black, the transmission of radiation to the surface of the support 22 is blocked and scattering and reflection are prevented.

Abstract: PURPOSE: To dispense with an extra working step for switching a chucking pawl by switching a chucking pawl changeover device simultaneously with a printing unit replacement device by combining these two devices. CONSTITUTION: A chucking pawl is provided in a dent 2 which is opened outwardly in a turning-over cylinder 1 and extends in parallel with a shaft. The operation of the chucking pawl is controlled by a cam roller 16 through a control lever and a bridge 15 and the pawl comes into contact with a drive cam 17 fixed on a machine base 4, resulting in the movement of the bridge 15. The cam roller 16 changes its position from the drive cam 17 to a drive cam 18. To move the bridge 15 in an axial direction, an eccentric body 19 is pivotally supported on the turning-over cylinder shaft 1 and is insetted in a bearing for the bridge 15.  The rotation of the eccentric body 19 is performed by a changeover shaft 21 through a miter gear, and the eccentric body 19 is pivotally supported, in a freely rotatable manner, in the turning-over cylinder 1, the free end part of the eccentric body 19 being set through a fixed gear 6 and a clamping member 12. The free end part of the changeover shaft 21 connected to a replacement gear 10 with speed change gears, and the rotary angle of the replacement gear 10 is changed to a fixed gear 6. Thus a chucking pawl control device is switched by the changeover shaft 21 simultaneously with a printing unit when it is replaced.

Title: Displaying light display
Inventor: GODBILLON VINCENT
IPC: F21V5/00
Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To present even lighting to an observer by forming the structure that the transferring striation changes the direction of the light to be emitted from two similar light sources related to a second element to the general light emitting direction. SOLUTION: A transferring striation S can change direction of the light beam arriving a transference zone R to a direction Y. For this purpose, the striation S is projected sufficiently far toward the inside of a displaying light display in relation to a surface SO3 in the direction Y, and crosses a light beam directed to a zone 450. The light beam arriving the surface SO3 at the angle α of incidence is reflected by the surface SO3, and reflected by a surface SO4 so as to pass through the zone R. Angle of inclination of the surfaces SO3, SO4 is set at a value capable of separating the light beam from a plate 50 in a direction nearly in parallel with the direction Y. Similarly, direction of the light beam arriving the surface SO4 at the angle β of incidence is changed to the direction Y. Consequently, nearly constant lighting light passes through the display in the direction Y.
