Abstract: PROBLEM TO BE SOLVED: To enhance cooling performance of an electronic package by a method, wherein a plurality of compressible heat conductive members which are connected thermally to an electronic device and a heat sink so as to be separable are arranged between the electronic device and the heat sink. SOLUTION: An electronic package assembly 10 comprises a circuit board 12, having a surface 16 provided with an electric conductor, and an electronic device 18 is connected electronically to the circuit board 12 by, e.g. a pin-in-hole solder connecting operation or the like. A plurality of compressible heat conductive members 26 are fixed and bonded to the surface of a heat sink 22.

Title: Panel structure of plasma display panel
Inventor: SHIBATA MASAYUKI
IPC: H01J11/36
Filed: 1997-12-15
Abstract: PROBLEM TO BE SOLVED: To expand a common region by shifting a normal operating voltage range for a selected phosphor, by differentiating a display cell structure for every color. SOLUTION: A width of an address electrode 29b for a phosphor 32b corresponding to the second color with a higher discharge starting voltage is made wider than address electrodes 29a, 29c corresponding to the first and third colors. The phosphor has a shape of a curve of the second order, a discharge starting passage can be considered to be along a line of electric force that starts from a neighborhood of the minimum value of the curve of the second order and reaches a surface of MgO film 27, and the discharge starts when its length and a potential difference between its both ends crosses a Paschen curve. When the width of the address electrode is widened, in comparison with the case where it is kept narrow, 38h for example among equal potential surfaces 38a-38i is expanded toward discharging space and a potential difference between both ends of the line of electric force is made big without changing the distance between both ends. Accordingly, an applied voltage to start discharge can be lowered.

Title: Image forming device
Inventor: TAKENOSHITA KATSUYUKI
IPC: G03G21/00
Filed: 1991-12-26
Abstract: PURPOSE:To prevent the output of an unproper copy even in the case where a document of a different size is mixed when both-side copies are taken from one-side documents by cancelling the setting of the mode only when the document of the different size is detected. CONSTITUTION:A sheet feed roller is tuned on, a pick-up roller 12b and a separation roller 12c are driven and the lowest one of documents D on a sheet feed tray 12a is taken out and sent to an exposure position. During the carrying of the document D, its size is detected by a resist sensor 12g and a size sensor 12h. The detected size of the document and the size of a sheet set first are compared in a processor. When they do not match, the both-side copy mode is cancelled. Then, a proper cassette is selected and a normal copy operation is performed by the one-side copy mode.

Title: Operationnal amplifier circuit
Inventor: KANAMARU JIRO
IPC: H03F3/45
Filed: 1996-12-25
Abstract: PROBLEM TO BE SOLVED: To increase a through rate while phase allowance is kept to be constant with a small circuit scale by providing first and second diodes between the emitters of first and third transistors and between the emitters of second and fourth transistors with prescribed polarity. SOLUTION: The diode D1 inserted between the emitters of the transistors Q1 and Q3 so that an anode is connected to the transistor Q1 and the diode D2 inserted between the emitters of the transistors Q2 and Q4 so that the anode is connected to the transistor Q2 are provided. Since the transistors Q1 and Q2 are emitter follower-connected to the input transistors Q3 and Q4 of a differential amplifier circuit 1A in an initial stage, large current is supplied to the initial stage differential amplifier circuit 1A only when the input voltage difference of a positive phase input signal S and an opposite phase input signal SB is larger than threshold voltage. Thus, the through rate can considerably be increased while stability is kept to be constant.

Title: Communication equipment
Inventor: AJISAWA HIRONAO
IPC: H04B1/40
Filed: 1997-11-30
Abstract: PROBLEM TO BE SOLVED: To attain communication available with an opposite party with a simple operation, when an incoming call is received in a vibration call reception mode. SOLUTION: When a noise level detected by a noise level detection circuit 35 decreases to a prescribed level or below in the vibration call reception mode, a system controller 50A discriminates reception and allows a vibrator 48 to vibrate to signal to the user of the arrival of an incoming call. Thereafter, when a PTT. SW46 is depressed, the vibration call reception mode is tentatively stopped and a transmission system is allowed to send a voice signal inputted from a microphone. When the PTT. SW 46 is released, the reception system is operated and the received voice is outputted from a loudspeaker. When the PTT. SW6 is not depressed or a state of no reception continues for a prescribed time, the original vibration call reception mode is automatically restored.

Title: Resin molding equipment
Inventor: UCHIYAMA NORIHIRO
IPC: B29C45/02
Filed: 1992-12-25
Abstract: PURPOSE:To obtain a resin molding equipment reduced in running cost by extending a life of a plunger which pressurizes a resin tablet inserted in a pot of a mold. CONSTITUTION:An elastic ring 11 is fitted in a groove 12 circumferentially formed on the outer peripheral surface of a plunger 10 inserted into a pot 3 of an upper mold 1. When the plunger 10 is inserted into the pot 3, the elastic ring 11 is brought into slide contact with the inner peripheral surface of the pot 3 by its elastic force. With the wear of the outer peripheral surface of the plunger 10 and the inner peripheral surface of the pot 3, the elastic ring 11 always comes into slide contact with the pot 3, thereby preventing an air entrapment from a clearance between the plunger 10 and the pot 3 and a loss of a pressurizing force of the plunger 10 on a resin tablet 9. The outer diameter of the elastic ring 11 is manually adjusted by a ring diameter adjusting means 14 incorporated in the plunger 10.
