Title: Cooler for liquid crystal projector
Inventor: WATABE MITSURU
IPC: H04N5/74
Filed: 1999-02-05
Abstract: PROBLEM TO BE SOLVED: To obtain a cooler for a liquid crystal projector that supplies a uniform cool wind to optical components and has reduced sound noise by designing a fan whose number of revolutions is decreased. SOLUTION: Since a wind guide plate 9 for directing wind flow flow is provided between a fan 8a and optical components 4, a draft to the optical components is uniformized. Since an upper exhaust fan 8b is provided to an upper exhaust port 5b, reduction in a wind pressure resulting from addition of the wind guide plate 9 can be compensated. Furthermore, since the wind guide plate 9 is formed to be a honey-comb by using a heat conductive material such as a metal and a Peltier element is fixed to the wind guide plate 9 so that good heat conductivity so obtained, the wind guide plate 9 is cooled enough to cool air passing therethrouh and rectifies the cool air. Thus the optical components can uniformly and effectively be cooled.

The brush 23 is moved by the ON-OFF control of the solenoid 52, by which the spread of the coating agent is maintained always at a proper  amount. Thereby, cleaning function is enhanced and the quality of copying is improved.

Filed: 1988-02-09
Abstract: PURPOSE:To conform with the contact surface of a pulley all the time and reduce the extent of noise as well as to lower a running noise by fitting each spherical projection at both ends of a pin, in spherical cavities of friction materials, and setting up these friction materials different in each contact area with the V-pulley at random. CONSTITUTION:Spherical cavities 7, 7' are installed in each inner surface of friction materials 1, 1', while each spherical projection 4a at both ends of a pin 4 being opposed, fitting it therein shiftably free motion, and these friction materials 1, 1', where a contact area of each contact surface of the friction materials 1, 1' to contact with a V-pulley differs in plural numbers of steps, are installed at random. In consequence, at the time of belt driving, a V angle at each side of both friction materials 1, 1' is freely followed and accords with a frictional surface with the pulley all the time. In addition, a position of an incomplete contact part or the like between the V-pulley and the friction materials 1, 1' is continuously varied, whereby a period of causing a collision and friction is also continuously varied at random. With this constitution, a pitch noise is reduced and, what is more, a running noise can be sharply lowered.

Title: Mass flowmeter
Inventor: SHIODA TAKESHI
IPC: G01F1/78
Filed: 1980-03-08
Abstract: PURPOSE:To measure mass flow rate by vibrating an omega-shaped pipe in which the fluid to be measured flows in the direction perpendicular to its traveling plane and detecting the rate of torsion generated between two symmetrically curved parts of the pipe. CONSTITUTION:The straight parts 1' of an omega-shaped pipe 1 of a circular section are fixed respectively to a base 2, and their terminals are connected to a pipe line system, then the fluid F to be measured is flowed. A permanent magnet 4 is fixed to the end of the pipe 1 and an electromagnet 6 is disposed in opposition to the permanent magnet 4, so that the pipe 1 is vibrated in the direction orthogonal to the traveling palne of the fluid F. Also, a torque beam 7 is spanned and fixed between the maximum spacing position of the curved prts 1'' of the pipe 1, and strain gages 8-11 are adhered to both surfaces and both ends thereof. As the pipe 1 vibrates, the vibration torque of the torsion of which the amplitude is proportional to the mass flow rate of the fluid is generated in the pipe, thereby causing the strain gages 8-11 to distort. These distortions are detected as the unbalance voltage of a bridge circuit, whereby the mass flow rate is measured.

IPC: E04G17/00
Filed: 1996-01-23
Abstract: PROBLEM TO BE SOLVED: To provide a supporting member that does not become bulky when stacked up in a plurality of layers. SOLUTION: This supporting member 1 is constructed in a shape wherein the cross section made by cutting in the breadthwise direction of its gutter part 2 formed in a gutterlike shape is formed so that the width becomes narrower as both side edges of the gutter part 2 approach the top 4 of the gutter part. Extensions 3 extending outward are provided at both side edges of the gutter part 2, and nail holes 6 serving as fixing parts are provided at the extensions 3. The supporting member 1, constructed as mentioned above, does not become bulky when stacked up in a plurality of layers, and therefore the supporting members can be transported easily while requiring a less space for storing at a construction site.  Furthermore, when the supporting members are used for supporting forms for concrete placing, the supporting members are less liable, because of their apparentness of falling at dismantling after being used for upright forms unless being removed with hands lent for holding, to incur accidents of falling with mistakes of not holding the supporting members 1 by hands on dismantling eliminated. The supporting members do not roll when arranged on horizontal forms.

IPC: B41J2/345
Filed: 1992-02-15
Abstract: PURPOSE:To prevent the damage and corrosion of a power supply unit or the like at the time of use in usual recording and to extend the life by forming semicylindrical glaze to the end part of a base over a range sufficiently longer than a heating resistor row in parallel to the heating resistor row. CONSTITUTION:Semicylindrical glaze 6 is formed to the end part of a substrate in the feed direction of a recording medium 8 with respect to heating resistors 3 in parallel to the arrangement of the resistors 3 and a feeding body is not purposely arranged on the glaze within the range coming into contact with the medium 8. Further, the glaze 6 is formed so as to protrude as compared with other part and, since it can be formed simultaneously with a glass glaze layer 2, the cost increase due to the formation of the glaze is eliminated. As a result, the running route of an ink ribbon 9 comes into contact with a thermal head during printing by the resistors and subsequently becomes a floated state until the contact with the glaze 6 and, therefore, the contact of the thermal head with the ribbon 9 is perfectly eliminated in the floated state and, since the feeding body 4 is not arranged on the glaze 6, said body A receives no damage due to the contact with the ribbon 9.
