Title: Warm air heated toilet seat
Inventor: TOYOKICHI HIDEFUMI
IPC: A47K13/30
Filed: 1998-03-09
Abstract: PROBLEM TO BE SOLVED: To instantaneously increase the temperature of a sitting surface without decreasing the strength of a toilet seat main body. SOLUTION: In this toilet seat, the wall surface of a warm air passage 12 corresponding to the heating area of the sitting surface 10a of a toilet seat main body 10 has a recessed and projected surface 9 and the heat transmission area in contact with warm air is enlarged. Thus, heat transmission efficiency is improved by the increase in the contact heat transmission area and the sitting surface 10a of a toilet seat surface is instantaneously warmed. Also, if a member with excellent heat transmissivity is incorporated to the recessed and projected part 9, the heat transmission efficiency is further improved. The warm air passage 12 is separated into top and bottom parts, so that the warm air passage on the top side is used as the supply passage of the warm air while the warm air passage on the bottom side as the reflux passage of the warm air.  Thus, by heat transmission of the warm air at a high temperature before heat exchange, the temperature of the sitting surface 10a is instantaneously raised. Also, cold air after heat exchange is discriminated, and temperature decrease of the warm air and of the toilet seat surface 10a is prevented.

Title: Roll
Inventor: HIROHATA NOBUYUKI
IPC: B65H5/06
Filed: 1985-03-18
Abstract: PURPOSE:To protect the printing face from damage by distributing the pressure air to be fed through the path of core shaft into the gap between an annular member and a pipe through discharging section to achieve contactless condition thereby achieving the synchronous rotary speed with a carrying object instantaneously at initial rotation of pipe. CONSTITUTION:The air fed to a path 2 of respective core shaft 1 will go through a through-hole 7 toward the entire circumference of an annular groove 6 to achieve proper pressure distribution between the outercircumference of an annular member 4 and the innercircumference of pipe 3 while discharging through meshes 9 thus to maintain the annular member 4 and the pipe 3 contactless. The air directing toward the inside of annular member 4 will go through a through-hole 10 toward a through- hole 18 while the air directing toward the outside of the annular member 4 will go toward the through-hole 18 thus to limit the discharging amount of air through barrier wall members 25, 26. Furthermore, the air directing from the path 2 to another path 17 is ejected uniformly to the opposite sides of flange 14 to maintain the annular boards 15, 16 contactless while discharged through a central through-hole and the through-hole 18 to the atmosphere. Consequently, it will cause slippage between the carrying object and the roll thus to never damage the film face.

Title: Method of measuring composition of fatty acid
Inventor: MORITA AKIRA
IPC: G01N30/06
Filed: 1997-03-12
Abstract: PROBLEM TO BE SOLVED: To enable the simple, highly-accurate, and direct measurement of the composition of fatty acid by dissolving the fatty acid in a mixed solvent of a ketonic solvent and formic acid. SOLUTION: Fatty acid is dissolved in a mixed solvent of formic acid and a ketonic solvent. Acetone, methyl ethyl ketone, etc., preferably acetone is used as a ketonic solvent. The mixing ratio of formic acid and a ketonic solvent is e.g. 100/0-30/70 by capacity ratio, preferably 60/40-40/60. Fatty acid measurable in this method is fatty acid with an alkyl chain length of carbon number 3-12, preferably fatty acid with an alkyl chain length of carbon number 4-8. The concentration of fatty acid is e.g. 0.1-5, preferably 0.1-1. As there is no need for the formation of derivatives, it is possible to perform measurement in a shorter time in comparison with a conventional method of measurement by gas chromatography after methyl esterification.  In addition, as the time and effort for the formation of derivatives are saved, this method is used with case as a means of an automatic analysis and is suited for an analysis for quality control.

Title: Method for canceling adjustment in parking lot control terminal device
Inventor: KITAJIMA JIRO
IPC: G07B15/00
Filed: 1998-02-24
Abstract: PROBLEM TO BE SOLVED: To simply continue to perform readjustment that uses a parking ticket that is cancelled in the middle of adjustment by storing information that it is paid by a note by the time when adjustment is canceled on a parking ticket. SOLUTION: An MPU performs cancellation processing when it decides that cancellation is made at a prescribed time (S7). For instance, when a free pass ticket is used, information that free service is available is additionally and magnetically written as reduction information on a parking ticket and it is returned to a parking lot user (S8 and 9). The parking ticket is read by a magnetic ticket reader/writer to adjust a parking fee again by using the parking ticket that is canceled the last time (A1). The MPU calculates a parking fee from a vehicle entrance time by the current time based on preliminarily set parking fee system information (S2).  The MPU decides whether or not the preceding reduction information exists in a read parking ticket (S3), and when it exists, the parking ticket is reserved internally and the MPU performs processing in accordance with amount information that is additionally written on the parking ticket the last time from a parking fee calculated this time (S14).

Abstract: PURPOSE:To prevent heat loss by feeding concentrated absorption liquid to a storage tank and condensed water to a water tank to be stored, removing it from the tank as required, and feeding it to the absorber of a steam absorber, thereby transferring liquids of different concentrations from a heat source side to a cold generator side to transport heat. CONSTITUTION:Dilute absorption liquid is scattered to a concentrator 21 of an absorption liquid generator 2 toward heat radiation end 23 of a heat pipe, and heated to generate steam. The generated steam is introduced via a tube 107, cooled with cooling water to be discharged through a heat transfer tube 24 and a tube 108 to be condensed, fed to a water tank 5 through a tube 106 to be stored. The absorption liquid condensed by evaporation is fed through a tube 103, mostly recirculated through a tube 104, and the remainder is introduced to the lower layer of an absorption liquid storage tank 3 through a heat exchanger 6 and a tube 105. The upper layer of the tank 3 stores dilute absorption liquid, to be introduced into the exchanger 6 through a tube 101. The concentrated absorption liquid is scattered on a cooling heat transfer tube 43 mounted in an absorber 41 of a steam absorber 4 by a scattering nozzle 45. Thus, heat recovery rate can be improved.
