Abstract: PROBLEM TO BE SOLVED: To allow an angle part to easily bend following external force acting on it without impairing a lock function in a curved state of the angle part in an angling instrument having an automatic lock function. SOLUTION: Steel balls 38a and 38b engage with each other together with a taper surface of a driven rotary body 31 connected to a pulley 20, upper/lower end surfaces of a regulating member 37 for exhibiting an automatic lock function are sandwiched between an annular ring-shaped friction plate 51 arranged on a ring nut 50 threadedly inserted into an inside surface of a support drum 15 and a push-up ring 54 energized by a disc spring 52 to be installed between them so as to operate prescribed frictional force being a lock load, and when external force acts on an angle part, the regulating member 37 is rotated together by following the driven rotary body 31. That is, a driven part is arranged, and the upper end surface of the regulating member 37 is allowed to abut to the annular ring-shaped friction plate 51.

Title: Fixing method for double cam and device therefor
Inventor: KIMURA SEIICHI
IPC: F16H53/02
Filed: 1998-02-16
Abstract: PROBLEM TO BE SOLVED: To prevent loosening of a double cam from a drive shaft by vibration caused when the drive shaft is rotated and driven. SOLUTION: When a double cam 1 is fixed to a drive shaft 5, a nut 15 having a wedge portion 17 is threaded in a thread 13 formed on an outer periphery of the drive shaft 5 and the wedge portion 17 is engaged with the engaged portion 19 formed on the double cam 1 to fix the double cam 1 to the drive shaft 5. Thus, a strong tightening force acts by adding a wedge force of the wedge portion 17 to an axis force of the nut 15. It can be prevented to loose the double cam 1 from the drive shaft 5 by vibration caused when the drive shaft 5 is rotated and driven.

Title: Recording paper for thermal printing
Inventor: ITO HIROSHI
IPC: B41M5/28
Filed: 1988-02-16
Abstract: PURPOSE:To obtain a recording paper having a good shelf stability and eliminating the need for a thermal head having a heater, by using an optically isomerized polymer for a wall material of a capsule containing a heat-sensitive dye. CONSTITUTION:Ultraviolet light irradiation of a recording paper causes a change in the steric conformation of an optically isomerized polymer of a capsule wall material, thus imparting a permeability to substance to a capsule wall 3 and emitting a heat-sensitive dye 1. By being successively heated, the ultraviolet light-irradiated part forms a color by the reaction of the heat-sensitive dye 1 with a color developer 4. Furthermore, in the ultraviolet light-irradiated part the optically isomerized polymer of the capsule wall 3 returns to a former steric conformation to be unpermeable to substance. An unirradiated part has no possibility of forming a color due to heat. In this manner, the need for mounting a heater for every printing dot is eliminated, a heat roller etc., for heating all over the surface is made available, and a high shelf stability can be obtained because the heat-sensitive dye is separated from the color developer by capsules.

Filed: 1980-03-19
Abstract: PURPOSE: To obtain a ceramic transparent piezoelectric material for vibrator by setting the content ratio of La and the content ratio of Zr/Ti of a PbLaZrTiO compound within a prearranged range.  
     CONSTITUTION: A ceramic material PLZT of lead zirconate-lead titanate added with La has four phases such as strong dielectric trigonal system, pyramidal quadratic system, constant dielectric cubic system, and counter strong dielectric pseudocubic system. Of these phases, only the pseudocubic system AFE and a part of the cubic system FETet have superior photopermeability and piezoelectricity, properties, so that they have a region of composition suitable to a transparent vibrator. A part of the AFE is displaced to an FE phase along a phase through application of a voltage, becoming a region suitable to a vibrator. Also, even in the region of the FETet phase, a region exists where photopermeability and piezoelectricity properties are superior after polarization process. If the choice is made in Pb 1-x La x  (Zr y Ti x ) 1-x/4 O 3  in such manner that X equals 6∼12 atoms %, y/z equals 65/35∼ 50/50, a ceramic piezoelectric element having superior photopermeability, and piezoelectricity properties is obtained.

Abstract: PROBLEM TO BE SOLVED: To highly accurately manufacture a wood shaft having no backlash produced during use at low costs by forming, from one end of a diameter adjusted wood thin bar, an annular groove slightly larger in width and depth than a locking projection in a position more than a distance from the opening of a sheath member to the locking projection and grinding a tip to be gradually smaller. SOLUTION: A machining bar obtained by coining the outer surface of a thin bar wood raw material with a coining device is supplied to a machining device for forming an annular groove, and an annular groove is accurately formed in a specified position from the end surface of a base part by a finishing device. For this machined wood, the diameter of the base part is a place needing accuracy for inserting a wood shaft 10 into a sheath member (a) and uniformly pressing the same to be accurately contacted with its inner surface. Thus, by arranging the finishing device in the machining device for groove formation, the annular groove is re-adjusted. Then, the diameter-adjusted machined material is fed to a last tip part machining device and its tip part is machined to be small. Then, after this step, the diameter of the base part is re-adjusted by the finishing device again.

Title: Information retrieving system
Inventor: NAKAYAMA SHUICHI
IPC: G06F17/30
Filed: 1988-02-17
Abstract: PURPOSE:To shorten the application time of the subscriber line of a computer containing a data base by retrieving a table of contents requiring the transmission of detailed information between a data terminal and a switchboard. CONSTITUTION:When a request is received from a data terminal 6 for transmission of a table of contents, a switchboard 1 refers to a table-of-contents managing file 5 via a transmission means 7 to send the requested table of contents to the terminal 6. When the terminal 6 instructs the table of contents requiring the transmission of the detailed information, the switchboard 1 refers to the file 5 via an instruction connecting means 8 to instruct the transmission of the detailed information on the table of contents of a computer having a table of contents of the detailed information. At the same time, the switchboard 1 connects the computer to the terminal 6 via a subscriber line. Therefore, the subscriber line which stores the computer is not used before a table of contents requiring the transmission of the detailed information is detected. Thus the application time of said subscriber line is shortened and the effective application is ensured for the subscriber line.

Abstract: PURPOSE:To ensure that the passage of a vehicle through a point which should not be passed can be securely recognized by an observer, the driver of the vehicle or the like, by a construction wherein an alarm issuing part provided in a piston is driven by inward and outward movements of the piston. CONSTITUTION:A piston 4 is provided therein with an alarm issuing part 10 comprising a transmitting part for emitting sound or light, a driving part for the transmitting part, a power supply part and the like, and the driving part is supplied with electric power from the power supply part upon operation of a switch 9 provided on the bottom face of the piston. This system is buried underground, with the piston 4 engaged with a lock claw 3. When a mobile body such as a vehicle passes over the piston 4, the weight of the mobile body depresses the piston 4 against a spring 7, whereby the lock claw 3 is disengaged, and the piston 4 is projected outward, causing the alarm issuing part 10 to issue an alarm. The passage of the mobile body can therefore be securely recognized by an observer, the driver of the vehicle or the like.
