Title: Method for mounting semiconductor chip
Inventor: NAKAJIMA SATOSHI
IPC: H01L21/60
Filed: 1995-10-24
Abstract: PROBLEM TO BE SOLVED: To realize a method for mounting a semiconductor chip by which sealing resin can be filled in a short time without leaving any bubble in the clearance between a circuit board and a semiconductor chip by improving the method for filling the sealing resin in the clearance therebetween. SOLUTION: When the clearance G1A between a circuit board 20A and a semiconductor chip 10A is filled with sealing resin 40A, the resin 40A is applied to an area corresponding to a long side 101A. In addition, the area to be coated with the resin 40A is limited inside both ends of the side 101A (shown by an arrow mark A1). Then, the board 20A is directly heated from its rear side by a heat block BL, and the chip 10A is heated in non-contact by a light beam L (light energy) emitted to the rear side. As a result, the resin 40A is heated through both boards 20A and chip 10A and flows into the inside of the clearance G1A and it is cured thereafter.

Filed: 1995-09-29
Abstract: PROBLEM TO BE SOLVED: To enable the presentation of an accurate target even on a near distance examination by providing a target plate having a plurality of examination targets thereon, lighting the target plate from the backside and regulating a means for adjusting the transmittance according to a signal from a selecting means. SOLUTION: Putting on an electric switch, a regulating circuit actuates a back light 24 of a target presenting unit to light, to turn on all of liquid crystal devices 23a of a liquid crystal panel 23 to cut off so as not to transmit the back light. As a result, the presenting face of the target is looked as a deep-black state because the transmitted light is screened by a region (the surrounding region 22d) where the liquid crystal device 23a is not formed on the liquid crystal panel 23 and is printed black. At this state, by operating a target selection switch to cut off the electricity for the liquid crystal device 23a at the position corresponding to a selected target, and thereby transmitting the lighting light at this position to present only the examination target, the visual acuity of the subject can be determined according to the response of the subject.

Title: Speaker
Inventor: KOURA TETSUJI
IPC: H04R9/04
Filed: 1994-11-10
Abstract: PURPOSE: To reduce the rise of temperature of a voice coil to obtain a speaker having a high resistance to input and less distortion by cutting inside and outside peripheral faces of a magnetic gap to provide air holes where the magnetic gap is partially expanded and forming an air path. CONSTITUTION: The outside peripheral face of a center pole 15 is partially cut to form a first air hole 29 between this outside peripheral face and the inside peripheral face of a voice coil bobbin 21. The inside peripheral face of an upper plate 18 is partially cut to form a second air hole 30 between this inside peripheral face and the outside peripheral face of the voice coil bobbin 21. When the speaker is operated, the air current passing the air hole 29 cools the inside peripheral face of the voice coil bobbin 21 and the center pole 15 adjacent to the voice coil bobbin 21. The air current passing the air hole 30 directly cools the outside peripheral face of a voice coil 20 and cools the upper plate 18, thus reducing the rise of temperature of the voice coil 20.

Title: Method for recording optical disk
Inventor: KARUBE HIROO
IPC: G11B7/125
Filed: 1991-10-24
Abstract: PURPOSE:To perform the light modulation overwriting with a low error ratio at the recording and reproduction by making the laser deletion power to be applied in the case of a short recording pit interval shorter than that in case of a long recording pit interval. CONSTITUTION:An optical disk capable of light modulation overwriting is irradiated with the higher laser power in the case of forming a recording pit and with the lower laser power than the recording time in the case of deletion. In short, the recording pit is recorded at the temperature higher than T1, and deleted within the temperature range from lower than T1 and up to T2. When a recording bit is short, the location which is originally under the T2 is fluctuated by the thermal interference between recording bits, increasing an error ratio. This tendency is remarkable in the optical disk capable of light modulation overwriting since the optical disk is irradiated with laser for deletion during recordings. An error ratio is reduced if the laser power at the deletion is controlled so as to prevent the excess temperature rise of the deletion section of a recording film.
