Filed: 1996-09-09
Abstract: PROBLEM TO BE SOLVED: To avoid easy disconnection of the neck part of a bonding wire even under violent oscillation and forced heat cycles by a method wherein sidewall parts suppressing the movement of gelatinous resin in a bonding pad part are provided near the bonding pad. SOLUTION: Sidewall parts 30 are provided near on both sides of a bonding pad 27.

Title: Electronic musical instrument
Inventor: MATSUMOTO MITSUHIRO
IPC: G10H1/053
Filed: 1998-08-25
Abstract: PROBLEM TO BE SOLVED: To reduce the burden for instruction operation required on a performer, in musical performance where a musical sound generating instruction for generating a musical sound, and a control instruction for an effect for the generated musical sound are conducted at the same time in an electronic musical instrument. SOLUTION: A musical sound generation instruction means 3 instructs a musical sound generating means 1 for musical sound generation. An operation position detecting means 4 is operated by a performer to detect an operation position. An operation detecting means 5 detects operation start and finish of the means 4. A control means 6 controls the degree of sound change to be imparted to the musical sound generated by a musical sound changing means 2 based on operation-positional change between the operation position detected by the operation position detecting means 4 when the operation start is detected by the operation detecting means 5, and the present operation position detected by the means 4. Requirement for accuracy is reduced thereby as to the operation start position of means 4 for the performer.

Title: Production of liquid crystal display panel
Inventor: HANAOKA KAZUTAKA
IPC: G02F1/1339
Filed: 1988-09-22
Abstract: PURPOSE:To form a uniform space for packing liquid crystals with high precision between a TFT substrate and a confronting substrate by preventing spacers from contact with the TFT substrate face by means of a groove formed on the confronting substrate. CONSTITUTION:The confronting substrate 21 is arranged to face oppositely to a TFT substrate 1 on which plural display electrodes 3, thin film transistors (TFT) 4, scan path line, data path line 6 and an orientation film 13 are successively formed, so as to face and TFT 4, scan path line, and data path line 6 oppositely to a groove 24 interposing spacers 7 having, for example, 5mum diameter, which are scattered on the TFT substrate 1, and the periphery of the substrates is sealed air-tightly in pressurized condition. Thus, the spacers 7 distributed spotly on the TFT 4, scan path line and data path line 6 are prevented from contacting with the substrate 21 surface by the groove 24 formed on the confronting substrate 21. By this method, a space 27 for packing liquid crystals is formed uniformly between substrates 1, 21 with improved precision of the space without causing crumbling of TFT 4, data path line 6, etc., by the spacers 7.

Title: Network load controlling system
Inventor: MORIYAMA ATSUSHI
IPC: H04M7/06
Filed: 1986-10-06
Abstract: PURPOSE:To limit a new load and to reduce a load by sending out a line closing signal to a termination system trunk to the opposite office through a common signal line when an overload is generated. CONSTITUTION:When an exchange EX2 is overloaded, a central processor CC2 sends the line closing signal to exchanges EX1 and EX3 of opposite offices through the common signal line. The central processors CC1 and CC3 of the EX1 and EX3 set corresponding origination system trunks in origination closed state in main storage devices MM1 and MM3 and send a line closure completion signal back to the EX2 through the common signal line. The central processor CC2 having received it sets the origination closure states of the corresponding trunks by the opposite offices in a main storage device HM2. Consequently, the EX1 and EX3 do not select the closed trunk for origination, so the traffic intensity of the EX2 decreases and the load can be lightened.

Title: Fine adjusting method for microscopic observation
Inventor: INABA FUMIO
IPC: G02B21/32
Filed: 1992-09-07
Abstract: PURPOSE:To provide a micromanipulator for finely adjusting a minute specimen with non-contact. CONSTITUTION:A laser beam 12 having non-point-symmetrical intensity distribution (an elliptical pattern) is focused on a specimen 16 having non-point- symmetrical refractive index distribution by means of an objective lens 14. In this case, the specimen 16 is caught in the condition of conforming the major axis direction of the laser beam 12 to the major axis direction of the specimen 16. This is derived from that the catching condition is dynamically stable against the specimen 16 having non-point-symmetrical refractive index distribution, because non-point-symmetrical catching force is generated due to non-point- symmetrical intensity distribution of a laser beam. Consequently, when the major axis direction of intensity distribution of the laser beam 12 is rotated, the caught specimen 16 is also rotated accompanying it, and hence the specimen can be finely adjusted.

Title: Spiral handle for umbrella
Inventor: MAKITA MITSUNORI
IPC: A45B9/02
Filed: 1993-08-18
Abstract: PURPOSE:To cancel many faults at the time of storage by spirally constituting the handle of an umbrella and freely bending or extending it. CONSTITUTION:A handle 2 attached to the head of a supporter shaft 1 of an umbrella 3 is spirally formed and can freely be bent or extended. Since the shape of this spiral handle 2 is formed in a semicircular hook, when wind strongly blows in the case of use at rainfall time, the umbrella can surely be grasped, force is effectively applied, and the sense of stability can be kept. Even for carrying it, the umbrella can be not only grasped by a hand but also hung on the arm, both of hands are made free, and it is convenient for acting. Further, when using the umbrella for both tall and short persons, by extending the spiral handle 2, the supporter shaft 1 of the umbrella is extended, and convenience is improved. At the time of storage, by extending the spiral handle 2, the supporter shaft 1 of the umbrella is made straight, and the umbrella can easily be dealt with and arranged without requiring any wide space.

IPC: F23N5/18
Filed: 1993-09-01
Abstract: PURPOSE:To obviate a failure due to breakage of a main part by providing a degradation judging element which judges degree of aged degradation of each part of a hot-eater supply apparatus by comparing a present value with a normal data and degradation data. CONSTITUTION:As an example of comparison judgement at a degradation judging element 83, thermal efficiency (n) is used, where n=Qw(Th-Tw)/QgK, and Qw: water flow rate, Th: hot water temperature, Tw: water temperature, Qg: gas flow rate, K: heating value of gas per unit volume. And (n) shows what percentage of calories emitted from combustion gas is transferred to water. A normal data of (n) is about 80%. When this value is less than 75%, it is judged that 'degradation' has occurred, which is displayed on a display device 85. And at the same time, a signal to the effect that durable limit has been reached also is sent to a degradation control element 86, whereupon the element 86 sends a signal to a gas flow regulating valve 41 to lower an upper limit of gas flow rate.

Abstract: PURPOSE:To improve efficiency of a casting cycle without any loss time in molten metal supplemental time by arranging a gate valve in a passage connecting a molten metal holding furnace for holding under pressurizing the molten metal filling up into cavity in a die with a molten metal supplemental furance. CONSTITUTION:After transferring the necessary prescribed quantity of the molten metal M into a molten metal holding chamber 20, the pressure in the molten metal supplemental furnace 16 is reduced and also the gate valve 62 is closed to shut off communicating state between the molten metal holding furnace 12 and the molten metal supplemental furnace 16. By again introducing inert gas into the molten metal holding furnace 12, the molten metal M is filled up into the cavity 50 in the die 14. As the supplement of the molten metal is executed at the time of opening the dies 14, sequential casting operation is executed to this low pressure casting apparatus 10 without any stopping the operation. Further, as the molten metal M is not brought into contact with the outer air during flowing, the development of oxide in the molten metal M is prevented as much as possible.
