IPC: B62D11/08
Filed: 1998-11-20
Abstract: PROBLEM TO BE SOLVED: To prevent mud from sticking to a first transmission belt mechanism by placing an upper end portion of a chain case at a level higher than an upper crawler mechanism that moves circularly either forward or backward and installing the first transmission belt mechanism between a transmission input shaft provided on the upper end portion of the chain and a drive shaft of a prime mover. SOLUTION: A traveling mechanism 1 is equipped with a pair of front and rear driven wheels 11, 13, a drive wheel 15 operatively connected to a transmission 5, and a wound crawler 16. A lower end of a chain case 78 installed inside the crawler 16 is operatively connected to an input shaft of the transmission 5 that is located at a level lower than an upper mechanism that moves circularly either forward or backward. An upper end of this chain case 78 is placed at a level higher than the upper mechanism that moves circularly either forward or backward of the crawler 16 and a first transmission belt mechanism 125 is installed between a transmission input shaft 78b on the upper end of the chain case 78 and a drive shaft 76a of a prime mover 4. This allows the whole body of a first transmission belt mechanism 125 to be placed on the upper side of, and in isolation from, the upper crawler mechanism moving circularly either forward or backward, preventing mud from sticking to it.

Filed: 1990-11-30
Abstract: PURPOSE:To obtain an orchestral video (karaoke) image where places to be sung are easily found even if timing with accompaniment deviates by mixing and recording background video information, sound information on the accompaniment of an object song, and character information on the text, and character information whose song characters are colored as the sound information advances, and recording them on a video recording medium. CONSTITUTION:A mixer 2 mixes the video information, character information, and character information whose song characters to be sung are colored by a hue changing device as the advance of the voice character and then they are mixed with the sound information as an accompaniment generated by a sound information supply device 5 to generate a mixed song 6, which is recorded by a recording and reproducing device 7 such as a video tape recorder. When the recording and reproducing device 7 is placed in playback mode, the video information A and character information B are displayed on a display device 9, and the accompaniment is reproduced by a sound generator 1. In this case, the character information B turns red from white in order as the advance of the accompaniment, so the user sings the song by following characters which turn red over a look at the display device 9 to time himself or herself with the accompaniment.

Title: Airtight terminal
Inventor: ANDO KENICHI
IPC: C03C8/24
Filed: 1994-12-08
Abstract: PURPOSE: To provide an airtight terminal having an aluminum-or aluminum- alloy-made metallic base and capable of sealing an iron-nickel-alloy-made terminal at appropriate sealing strength without using a metallic ring. CONSTITUTION: In this airtight terminal, a lead terminal insertion hole 2 is provided on an aluminum-or aluminum-alloy-made metallic base 1, and an iron- nickel-alloy-made lead terminal 3 is inserted into the lead terminal insertion hole; and this airtight terminal is sealed by high and low melting point glasses 41 and 42 (hereinafter referred to as glasses 41 and 42). Glasses 41 and 42 are laminated lamination glasses, and a glass layer for sealing the lead terminal 3 is the nonleaded high melting point glass 41 and a glass layer for sealing the metallic base is the high-lead low-melting-point glass 42.  Consequently, since a conventional low-melting-point glass is used on the aluminum-or aluminum-alloy-made metallic base side while a nonleaded high-melting-point glass is used on the lead terminal side, the lead terminal can be well sealed to the metallic base without detracting mechanical strength.

IPC: A61B5/055
Filed: 1989-12-22
Abstract: PURPOSE:To obtain the same image as that which is obtained at the time when an observer observes a reagent in the same posture and changing only an eye angle by determining rotation/inversion information of all images, based on some eye direction as a reference. CONSTITUTION:First of all, a positioning image 20 is reconstituted of three- dimensional image data 10. Subsequently, in order to reconstitute a rotary image, the number of rotation axis cross section pieces of a cross section, and the angle designation are set by using a slice information setting device 60 and a position information setting device 70. Next, each cross section is determined by a rotation and an inversion of the image. For instance, in the case of reconstitute an image by changing an eye a little with respect to a sagittal cross section image, it will suffice that the eye direction is set to the eye direction of the sagittal cross section, and a rotation and an inversion in that case are applied to all images. Thereafter, the image corresponding to the cross section defined by an angle alphai is reconstituted. The image of one piece each is calculated in accordance with a prescribed rule for giving a picture element value from three-dimensional image data, with regard to each picture element point, and executed by a calculating unit 50.

Title: Multiprocessor system
Inventor: KUROSAWA KENICHI
IPC: G06F9/52
Filed: 1990-11-28
Abstract: PURPOSE:To synchronize plural processors by using a small number of instructions by enabling synchronizing facilities to control the synchronism of their processor element while grasping the state of other synchronizing facilities through a bus arbitrating circuit. CONSTITUTION:A synchronism control means that the synchronizing facilities have grasp the execution state of a register transfer instruction on other synchronizing facilities A4 through the bus arbitrating circuit A5 and during the execution of the register transfer instruction, register transfer is carried out through a communication bus if transfer-destination synchronizing facilities are executing a corresponding register transfer instruction. When the opposite synchronizing facilities are not executing the corresponding register transfer instruction, this processor element A1 is stopped temporarily until the opposite synchronizing facilities execute the corresponding register transfer instruction to obtain synchronism with the transfer-destination processor element. Consequently, the processor elements can be synchronized by using a small number of instructions.
