Abstract: PURPOSE:To obtain a printed board in which a surface mounting type component can be mounted with high reliability by connecting a reflow pad to a rear wiring pattern by a connecting conductor connected to the pad and an inner wiring pattern, and a lead conductor connected to the rear pattern and the inner wiring pattern. CONSTITUTION:A printed board 10 is formed by thinly covering the inner surface of a blind hole 14 opened on the way in a direction of a rear surface with a region of a reflow pad 11 of a copper foil. The pad 11 is electrically connected to a rear wiring pattern 12 by a cuplike connecting conductor 15 electrically connected to the pad 11 and an inner wiring pattern 13 of a copper foil formed previously in the layer of a board 18, and a pipelike lead conductor 17 formed by thinly covering the inner surface of a lead hole 16 punched out of the region of the pad 11 to be opened in a direction of the front surface with the region of the pattern 12 to be connected to the pattern 12 and the pattern 13.

Title: Cooling device for projector
Inventor: ABE SHUNICHI
IPC: G03B21/16
Filed: 1987-10-29
Abstract: PURPOSE:To fully cool a projection part without generating noises offensive to the ear while continuously reading images by making the rotation of a fan for cooling the projection part of the projector at low speed after keeping it at high speed for a certain time and stopping it after a certain time passes in case of making the rotation of the fan off. CONSTITUTION:The lamp cooling fans 13 and 14 are controlled so that they are rotated at high speed while lighting a lamp and until a certain time passes from a moment when the lamp is turned off and stopped after they are rotated at low speed for a certain time thereafter. A certain time when they are rotated at high speed after turning off the lamp is set longer than the time when the lamp is off in case of continuously reading the images. Even if the lamp is temporarily turned off while continuously reading the images, high speed can be kept since the high speed rotation of the fan is continued until next lighting. The high speed rotation of the fan is continued for a certain time after completing reading and thereafter, the fan is stopped after the low speed rotation of it is performed for a certain time. Thus, the projection part can be fully cooled and noises offensive to the ear are not caused.

Title: Comb-line filter
Inventor: SUGITA KEIZO
IPC: H03H17/06
Filed: 1985-12-04
Abstract: PURPOSE:To lower a noise level generated at a change in a frequency characteristic by generating a designation signal designating a signal delay time changed at a prescribed time interval with a smaller value depending on the difference of the designation time just before and just after the designation time represented by a characteristic control signal changes. CONSTITUTION:An output data of a delay transition time setting circuit 11 is fed to a counter 16, to which a count pulse from a pulse generator is fed at each prescribed time Ts. The counter 16 is constituted in a way that its count changes from 1 until it is equal to a numeral represented by an output data of the delay transition time setting circuit 11 sequentially synchronously with an input signal Si by the count pulse. Noise is generated at an interval of one sample time over the delay transition time DELTAT and the delay time of a variable delay circuit 2 is changed gradually at each 1 sample time. Thus, a correlation always exists between adjacent samples outputted from the variable delay circuit 2 to reduce the noise level.

Title: Phase difference plate and its production
Inventor: KAMINOMACHI KIYOMI
IPC: B29C55/02
Filed: 1996-10-16
Abstract: PROBLEM TO BE SOLVED: To enable the uniform and high-grade display in the entire area of a display region by using a thermoplastic resin film formed in such a manner that the front surface layer having the relatively high glass transition point as compared with the central part in the thickness direction attains a uniform thickness. SOLUTION: This phase difference plate is so formed that the front surface layer having the relatively high glass transition point Tg attains the uniform thickness. In this case, the retardation value depends on the retardation value of the front surface layer having the high Tg and, thereafter, the retardation value is made uniform. An arbitrary low-mol.wt. compd. which has the high compatibility with the thermoplastic resin to be used and has the b. p. in a range of T-50 deg.C to 5+100 deg.C when the extrusion temp. is defined as T deg.C is used as a plasticizer. An example of the plasticizer that can be used includes phthalate plasticizers, etc. Further, the plasticizer is compounded at a ratio of 1 to 10 pts.wt. per 100 pts.wt. thermoplastic resin.  If the ratio thereof is below 1 pt.wt., the retardation value is not uniform and the resistance to heat is insufficient if the ratio is >=10 pts.wt.

Title: Rice seedling transplanter

Title: Device for locating fault in power transmission
Inventor: HASHIMOTO MAKOTO
IPC: G01R31/08
Filed: 1989-10-23
Abstract: PURPOSE:To simplify a circuitry by arranging two surge detection sensors to detect a surge attributed to a fault in a power transmission line and a judging device to determine the direction in which the fault is caused. CONSTITUTION:As part of a surge current at a fault shunts to the ground through a steel tower T when passing through the steel tower T, a fault current surge lowers in level. Hence, after the passage of the surge through the steel tower, a waveform of the surge becomes larger by a portion corresponding to a lowering of the level with a room available. As a result, even when an interval of optical CTs 10a and 10b is short, it becomes relatively easy to judge which of the optical CTs detects a surge current ahead in case of a fault. A judging device 20 receives an optical signal from the optical CTs 10a and 10b. When the optical signal from the optical CT 10a is received initially and the optical signal from the optical CT10 is received later, a fault is determined to be caused on a load side viewed from the steel tower T. This simplifies the construction as the judging device 20 is required only to judge the sequence of reception.

Title: Semiconductor device
Inventor: KATSUEDA MINEO
IPC: H01L27/06
Filed: 1991-10-22
Abstract: PURPOSE:To provide a semiconductor device which can suppress an excessive voltage applied across a transistor to be protected to a level lower than the breakdown voltage of the transistor to be protected. CONSTITUTION:A voltage dividing element 71 is connected to a terminal 11 to be protected and the gate terminal of a protective transistor 2 and applies a voltage decided by the voltage dividing ratio between voltage dividing elements 71 and 72 across the gate of the transistor 2. When the voltage applied to the terminal 11 reaches a prescribed protective voltage, the gate voltage of the transistor 2 is conducted. Therefore, the transistor 2 can absorb an excessive voltage by its original amplifying action only. In addition, since the transistor 2 and the elements 71 and 72 can be simultaneously formed on the same semiconductor substrate as that of a transistor to be protected, a semiconductor device which has a small size and does not require any external protective element can be obtained.

Title: Edge emission type led
Inventor: NANBA HARUMI
IPC: H01L33/10
Filed: 1987-10-29
Abstract: PURPOSE:To inhibit oscillation positively by forming structure in which one end face of a striped light-emitting region has an angle inclined to the striped light-emitting region in the main surface of an edge emission type LED. CONSTITUTION:A main surface 12 takes a shape that a rear-section end face 11 forms an angle to a striped light-emitting region 10. An inclined face in the oblique vertical direction to the main surface is shaped by etching the rear section end face 11 side. Since an inclination to the striped light-emitting region 10 in the face of the main face 12 is determined by photoengraving and an inclination is formed positively in the rear-section end face 11 of an oxide-film striped edge emission type LED, the light of the striped light-emitting region 10 is reflected in the direction of a side surface at all times on the rear section end face 11 as shown in the arrow, and is not reflected into the striped light- emitting region 10, thus inhibiting oscillation, then projecting only natural emitted light.
