Title: Data output device
Inventor: HAYASHIDA SATOSHI
IPC: G06F3/12
Filed: 1993-06-29
Abstract: PURPOSE:To provide a data output device which outputs and displays the characters in response to each transmission code in order to easily decide the contents of data and the areas of control errors. CONSTITUTION:In a data dump mode, a printer 1 prints the character strings showing the control contents of a control code (S10) when the transmission code is a control code (S4). When the transmission code is a character code (S4), it is decided whether the character code is a KANJI (Chinese character) code or not (S11). If so, the printer 1 prints a character corresponding to the KANJI code (S12). If not, the printer 1 prints a character corresponding to an ANK code (S13) together with a character corresponding to the transmission code such as an ASCII code, etc. When the value of the parameter accompanying the control code exceeds a prescribed range (S7), a marking showing this fact is printed to the parameter character.

Title: Disk lid structure of optical disk reproduction device
Inventor: FUJIKAWA YUKINOBU
IPC: G11B33/12
Filed: 1992-06-18
Abstract: PURPOSE:To prevent sound jump due to stagnation of air vibration in a storage space without inducing deterioration of appearance and reduction in strength by laying out a hole for relieving air vibration formed by a blind lattice so that it is shaped in a specified design. CONSTITUTION:A plurality of air vibration relief holes 21 which are constituted by a blind lattice 20 are formed at both sides of a transparent panel 8 of a disk lid 7. The blind lattice 20 falls in one piece with the section being in L shape from the main body of the disk lid 7. No air vibration relief hole 21 can be seen directly when viewed from the upper part and can be seen at all from the front, which is quite natural. A plurality of air vibration relief holes 21 at the left and right indicate a design where stripes are aligned in parallel when viewed from the top, thus preventing appearance from deteriorating. Also, the blind lattice 20 is in a large structure with a sectional secondary moment, thus preventing strength from deteriorating.

Title: Lead frame for light-emitting diode
Inventor: KOTAKI MASAHIRO
IPC: H01L33/60
Filed: 1986-07-07
Abstract: PURPOSE:To suppress dispertion of light and improve the light emitting efficiency by laminating LED elements and making the LED elements have positive and negative electrodes at the same side face. CONSTITUTION:At the tip of an anode lead members 10, a leveled face 11 and a reflected part 12 are formed in a body, One of the electrode parts of an LED is placed on the leveled face 11 and the reflected part 12 has a dike-shaped frame and surrounds about half of the LED in the vicinity of the side circumference face of its LED to be put by the electrodes. Even at the tip of a cathode lead members, the leveled face 21 and the reflected part 22 are formed in a body. The other electrode part of the LED is placed on the leveled face 21 and the reflected part 22 has the dike-shaped frame composing a remained other half of the LED and together with the reflected part 12 surrounds full circumferences of the side circumference face of its LED in the vicinity of the side circumference face of the LED to be put by the electrodes. In addition, the reflected parts 12 and 22 of both lead members 10 and 20 as well as all the surface of the leveled faces 11 and 21 are processed by silver plating and plated layers 13 and 23 are formed. Thus, the above members and others are so laminated that the light emitted in a direction along laminated layer faces having both positive and negative electrodes at the same side face are not dispersed and permit them to reflect in a right angle to laminated faces. As a result, the above performance of the lead frame drastically improves the light emitting efficiency.

IPC: B32B27/08
Filed: 1991-06-03
Abstract: PURPOSE:To improve the resistance to fluorocarbon and the adhesion between expanded polyurethane and non-expanded thermoplastic polyurethane-based resin by a method wherein rigid expanded polyurethane layer is laminated to the non-expanded thermoplastic polyurethane-based resin layer side of multilayered sheet, in which polyolefin- based resin layer is laminated to other layer. CONSTITUTION:By being extruded from a T-die extruder, multilayered sheet 14, in which polyolefin-based resin layer 11, bonding resin layer 12 and plastic polyurethane- based resin layer 13 are laminated to one another in the order named, is produced. By simultaneously pouring isocyanate solution and polyol solution in a weight ratio of isocyanate solution to polyol solution of 1:1 together with fluorocarbon 123 in the cavity of a decorative copper plate frame, in which the multilayered sheet 14 is installed, multilayered structural body 16, in which rigid expanded polyurethane layer 15 is laminated to the non-expanded thermoplastic polyrurethane-based resin layer 13 side of the multilayered sheet 14, is produced. Even when the stripping of the multilayered sheet 14 from the rigid expanded polyurethane layer 17 is intended, cohesive failure occurs in interface. In addition, since the multilayered sheet 14 absorbs little fluorocarbon 123, the resistance to the fluorocarbon is also favorable.

Title: Semiconductor device
Inventor: TAKEYA TAKESHI
IPC: H03K5/00
Filed: 1979-12-10
Abstract: PURPOSE:To enable to achieve the delay of signal and the shaping of waveform, by separating the discharge section for delay and the output terminal with a FET giving a constant voltage to the gate. CONSTITUTION:An FETQ3 is connected between the connecting point H and the output terminal O of FET1, and a power supply terminal VGG is connected to the gate of FETQ3. At the section A, a precharge clock P is fed, which is at high potential, and the connection point H between FETs Q1, Q2 and the output terminal O are precharged at the high potential. In this case, a voltage fed to the power supply terminals VGG is lower than the high voltage state of the precharge clock P, and FETQ3 is nonconductive at the end of the section A. Next, at the section B, when the input signal I is at high potential, a capacity C is dischaged. But, at the initial stage, the voltage at the terminal O is not lowered, and the discharge advances and the point H is lowered than the terminal VGG in potential by the threshold voltage of FETQ3, then FETQ3 is conductive. Thus, the wave shaping is made at the same time with the delay in signal.

Filed: 1984-07-30
Abstract: PURPOSE:To photograph with correct exposure by providing a means which detects the position of a shutter blade during the opening operation of the shutter blade and turning on this detecting means when the shutter blade is in the initial position and providing a check means which checks the turn-on state. CONSTITUTION:When a release button omitted in the figure is depressed up to the first stroke, the distance to an object is measured; and when the release button is depressed to the second stroke furthermore, the camera is brought into focus. Next, power is supplied to a rotor 19 in the shutter opening direction, and the shutter blade is opened. A photosensor 32 which detects the position of the shutter blade detects that the end part of the shutter blade traverses it, and the detection signal is latched in a D-type FF65, and exposure control is performed on the basis of this signal. If the sensor 32 is faulty, the D terminal of a DFF88 is kept low-level, and an AND gate 59 to which the output of an OR gate 85 is supplied is in the low level, and power is not supplied to the rotor 19. Thus, flash auto-photographing is inhibited when the sensor 32 is faulty, and photographing with the correct exposure is performed.
