Title: Optical device for laser beam machining
Inventor: MURAKAMI SHINGO
IPC: B23K26/12
Filed: 1988-10-28
Abstract: PURPOSE:To use an objective lens having high magnification and good resolution by placing the objective lens in an enclosed chamber, and placing a laser light lead-in window for leading a laser light into the enclosed chamber on the incident side of the objective lens. CONSTITUTION:From the upper part of an enclosed chamber 2, a laser light 6 is led in parallel into the enclosed chamber 2 through a laser light lead-in window 3. The laser light which is led into the enclosed chamber 2 is made incident on an objective lens 1, and focused or brought to image formation on a sample 4. Focusing of the objective lens 1 is executed by adjusting positions of X, Y and Z of an object placing table 5. In such a way, the title device is constituted so that the objective lens is placed in the enclosed chamber, and the laser light lead-in window is placed on the incident side of the objective lens. Since the laser light can be condensed directly onto the sample from the objective lens, the generation of an aberration at the time of passing through the laser light lead-in window is prevented, and since a distance between the objective lens and the sample is shortened, the objective lens having high magnification and good resolution can be used.

Title: Planar display device
Inventor: TSUTSUMI KUNIHIRO
IPC: G09G3/36
Filed: 1992-09-16
Abstract: PURPOSE:To realize a scroll function in a planar display device with a simple circuit constitution. CONSTITUTION:The coincidence between a horizontal address C and a scroll address D is detected and a timing pulse B is outputted. Thus, since the latch timing of a display data driver 30, etc., is changed, the read timing of display data A may be fixed timing, and the horizontal address C is used directly as an address to a display data RAM 26. Thus, a complex circuit generating a memory address for reading the display data corresponding to scroll is eliminated.

Title: Semiconductor package and its manufacturing method
Inventor: ISHIHAMA KAZUHARU
IPC: H01L21/56
Filed: 1995-10-20
Abstract: PROBLEM TO BE SOLVED: To accurately control the amount of liquid of a sealing agent which is injected into a cavity for sealing a semiconductor element and to automate the control of the amount of liquid in an airtight sealing type semiconductor package. SOLUTION: A taper part 15 as a gauge is provided at the corner in a cavity 4a for incorporating a semiconductor element 1. A sealing capacity which is obtained by subtracting the capacity of the semiconductor element 1 from the inner capacity of the cavity 4a and the sealing agent of the amount of discharge considering the discharge accuracy of a sealing agent 6 from a nozzle are subjected to primary injection into the cavity 4a, thus coating the semiconductor element 1. Then, the additional amount of the sealing agent into the cavity 4a is calculated by the taper part 15 and the remaining sealing agent 6 is subjected to secondary injection into the cavity 4a.  Since the taper part 15 which is plated causes color tone contrast by injecting the sealing agent 6, the position of a liquid surface 6a of the sealing agent 6 can be easily recognized by capturing an image by a camera with the taper part 15.

Title: Lubricating device in automatic transmission gear
Inventor: TAKASE ISAO
IPC: F16D25/0638
Filed: 1988-10-28
Abstract: PURPOSE:To prevent the abrasion of a clutch plate and the like by interposing a sealing member between a flange member positioned at the farthest outer part of a wet multiple disc clutch and the inner peripheral surface of a drum member, thereby providing the multiple disc clutch with appropriate oil bath lubrication. CONSTITUTION:Oil scattered around a sun gear S1 on the basis of the rotation of an input shaft 5 at the driving time of an automatic transmission gear passes through an oil pore 20 and the like and is received at the inner peripheral side of a clutch drum 12. In this case, because the part between the inner peripheral surface of the clutch drum 12 and the outer peripheral surface of a flange member 9 is closed by means of a sealing member 11, the oil does not flow out in the axial direction but its appropriate quantity is collected in a first clutch C1 part. Accordingly, the first clutch C1 is effectively oil bathed and lubricated with the appropriate quantity of oil. A clutch plate 8 and the like are thus prevented from excessive abrasion owing to the appropriate oil-bath lubrication with the appropirate quantity of oil.

Filed: 1986-11-18
Abstract: PURPOSE:To evade the abrasion of a contact and to prolong the service life of the contact, by moving a tilting lever provided with the contact with a sliding block by inserting an IC card, and abutting the contact with the storage cell of the card through the lever. CONSTITUTION:When the IC card 12 is inserted, the tip of the card 12 is abutted with the abutting plane of the sliding block 17, thereby, the block 17 is pushed to a position where data is processed. And the tip part of the card 12 moves a roller 18 upward, and the contact 26 is moved downward by tilting and inverting the tilting lever 23. Therefore, the contact 26 is pressed and brought into contact with the storage cell 13 on the card 12, then, the read and the write of the data can be performed. After the read the write of the data being completed, the card 12 is drawn out, and the roller 18 is moved downward, and the contact 26 is moved upward, then it is separated from a card plane. Thus, since the contact is brought into contact only with the contact point of the card, and is not brought into contact with other planes, the abrasion of the contact can be evaded, and also, the service life of the contact can be prolonged.
