Inventor: FUJIWARA SHIGEKI
IPC: B65G61/00
Filed: 1997-11-25
Abstract: PROBLEM TO BE SOLVED: To easily go up and down a narrow stairway without trouble even in a state of having a tall and heavy load. SOLUTION: A load mounting part 6 with a variable tilt angle to a body 1 is installed in the body 1 equipped with a stairway lifting travel part 2.

Title: Head driver for ink jet printer
Inventor: YAMASHITA AKIHIRO
IPC: B41J29/38
Filed: 1996-12-04
Abstract: PROBLEM TO BE SOLVED: To provide a head driver for an ink jet printer in which the cost and the size of a print head can be reduced while prolonging the service life. SOLUTION: Service life of a head is prolonged by charging and discharging capacitive elements C1-C5 with an AC current conducting a conductive ink thereby preventing electrolysis of the electrode. Charge/discharge of the capacitive elements C1-C5 is controlled selectively by charge/discharge control means CC1-CC5 provided for respective nozzles so that printing can be carried out through an arbitrary nozzle and the nozzles in a multi-nozzle head can be driven individually. Furthermore, a driver for a multi-nozzle head can be realized at low cost through a simple structure where the charge/discharge control means CC1-CC5 comprises a rectifier element arranged to pass only a discharging current and a switching means for controlling passage and interruption of a charging current.

Title: Microwave absorbing heating body
Inventor: INUKAI TAKAO
IPC: H05B6/74
Filed: 1989-12-15
Abstract: PURPOSE:To easily manufacture a heating body and make it difficult to crack by making a composite material of a structure such as ceramic fiber or the like and a silicon carbide matrix. CONSTITUTION:Silicon carbide is deposited by CVD method around fiber or the like of an assembly composed of ceramic fiber or whiskers to make the ceramic fiber or the like rigid. Since the silicon carbide can be highly pure by raising purity of gas in an Si source and a C source at this time, a body with specific electrical resistance of 10<4>OMEGA-cm or higher can be obtained. Thus even if microwaves with frequency and power for domestic use are radiated, the heating body absorbs the microwaves without discharge, is self-heated to at least 100 deg.C or higher, has sufficient resistance against a thermal impact caused by splash contact of water, etc., and is not easy to crack in usual dealing.

Title: Water cooling fuel cell
Inventor: MAKABE TERUO
IPC: H01M8/04
Filed: 1989-12-15
Abstract: PURPOSE:To restrict corrosion and choking of a water cooling system by regulating the density of dissolved oxygen in cooling water to be a desired density of dissolved oxygen which is suitable to the material of a battery cooling body and piping members composing the water cooling system for cooling a fuel cell main body. CONSTITUTION:Cooling water coming from a cooling water passage in a cooling body 1 passes a piping member 2 to be supplied to a steam separator 3. Here separated cooling water is branched at a piping member 4 by a branch piping member 18, sampling water is detected by a dissolved oxygen density gauge 17, and the density is regulated to a desired value by a dissolved oxygen density regulator 15. Cooling water after this regulation of the dissolved oxygen density is supplied by a cooling pump 6 through a piping member 7, a filter 8, and a piping member 9 to a cooling water passage of the cooling body 1. For example, by regulating the dissolved oxygen density to be more than 50ppb and less then 200ppb, the corrosion quantity of the piping member 2, steam separator 3, piping member 4 and piping member 7 consisting of material of carbon steel becomes the minimum. Corrosion and choking of a water cooling system can thus be restricted.

Title: Manufacture of pc product by instant demolding
Inventor: MORI HAJIME
IPC: E04G9/10
Filed: 1993-12-22
Abstract: PURPOSE:To prevent concrete surface from becoming coarse after demolding, and to make surface processing after demolding unnecessary. CONSTITUTION:Concrete 14 is cast into the space formed of molds 10 and a bed 9. As the concrete is hardened sufficiently, demolding is made by lifting the molds 10. A two-layer sheet 2 composed of a mold-releasing sheet 4 and a water-absorbing sheet 6 is arranged to the inside of the molds 10 before casting of concrete 14 with its water-absorbing sheet 6 facing the sides of the molds 10. Thereby, the surface of a PC product is kept covered with the two- layer sheet 2 attached when the demolding is made. The water-absorbing sheet 6 absorbs surplus moisture of the cast concrete 14 through the water permeable mold-releasing sheet 4. With the moisture A absorbed, a water screen layer is formed over the surface of the water-absorbing sheet 6 and left interposed between the two-layer sheet 2 and the molds 10.

Title: Vehicular occupant dialoging device
Inventor: SAKAGAMI YOSHIAKI
IPC: B60K28/06
Filed: 1998-10-09
Abstract: PROBLEM TO BE SOLVED: To improve the awakening effect of an occupant by detecting a dozing state of the occupant according to a state of voice detected by collecting/ analyzing a car inside sound, and outputting this as voice by generating a dialogic sentence on the basis of voice information on the occupent according to the dozing state. SOLUTION: A car inside sound is collected by the car inside sound collecting part 1 to detect whether or not voice is contained by analyzing information on a car inside sound collected by the voice analyzing part 2, and language is extracted so that this is recorded in the language recording part 3. An occupent state is detected by the occupent state detecting part 4 on the basis of a voice detecting signal. A prescribed dialogic sentence is successively generated by the dialogic sentence generating part 6 by using the language recorded in the language recording part 3 according to the occupent state so that this dialogic sentence is outputted from the voice output part 7.  According to this constitution since a dialogue with an occupent is repeatedly taken while successively changing the dialogic sentence according to a degree of a dozing state of the occupent, the occupant does not get used to the voice so that an awakening effect can be sufficiently exhibited.

Title: Wavelength conversion method and wavelength conversion element
Inventor: KOUDA HIKARI
IPC: G02F1/37
Filed: 1997-11-26
Abstract: PROBLEM TO BE SOLVED: To obtain short wavelength and high output wavelength conversion light in an ultraviolet region and to improve reliability in a conversion light output by cooling a wavelength conversion element to <=a specified temp. and performing wavelength conversion. SOLUTION: Relating to the wavelength within the range of about 100 nm from an absorption end 1 to a long wavelength side provided in the wavelength conversion element, since a refractive index is increased, surface reflection is large, and further, since the light is absorbed in material, when a transmissivity is measured, the transmissivity is reduced as it approaches the absorption end like a curve 2. However, relating to the material shifting to the short wavelength side as shown by the absorption end 5 of the wavelength conversion element by cooling the temp. of the wavelength conversion element to <=0 deg.C, an absorption spectrum is changed like the curve 6 compared with the case of not cooling, and the transmissivity 7 of the conversion light is improved.  Thus, the effect of the absorption is reduced, and dielectric destruction and generation of heat are suppressed, and the stable conversion light output is obtained.
