Patent JP-H03178153-A (JP)
Title: Semiconductor device
Inventor: ODA YOSHINORI
IPC: H01L23/50
Filed: 1989-12-07
Abstract: PURPOSE:To prevent the generation of cracks caused by vaporization expansion of water content existing on the interface between a die pad part and sealing resin, by cosituting a die pad by using at least two rectangular parts wherein the ratio of a short side and a long side is large. CONSTITUTION:A die pad 13 is constituted by using at least two parts wherein the ratio of the short side dimension and the long side dimension is large. In the vaporization expansion phenomenon of water content existing after exfoliation on the interface between the die pad part 13 and sealing resin, constant pressure is applied on the whole surface of the planar body whose periphery is fixed. In this state, stress becomes maximum at the central part in the long side direction of the planar body. The maximum stress can be reduced by decreasing the short side dimension of the planar body. Hence the stress generated by vaporization expansion of water content existing on the interface between sealing resin 15 and the die pad can be reduced, and the generation of cracks can be restrained.

Abstract: PURPOSE:To suppress high voltage leak from a fluorescent screen to prevent circuit breakage and stably apply high voltage to the fluorescent screen by providing an escape groove at a contact between a fixing means and an insulating means of an electron beam control means. CONSTITUTION:As a means for insulating and fixing an electron beam control means 2, an insulating bush 1 and an insulating spacer 3 made of ceramic are used and fixed by a flat countersunk head screw 4 and a nut 5. With a groove 6 provided on a slope of the insulating bush 1, metal of a lower part of the head of the screw 4 is rubbed against the slope under the groove 6 of the insulating bush 1 when the screw 4 and the nut 5 are fastened, and the metal is attached only to the slope under the groove 6 of the insulating bush 1 so that the attached metal does not protrude from the head of the screw 4 nor come out as a protruding metal piece. Thus leak and emission of high voltage is suppressed when high voltage is applied to a fluorescent screen so that high voltage can be stably applied.

Abstract: PURPOSE:To form the interphone with a monitor function by adopting the structure for the interphone to which an existing telephone set is fitted and fitting the telephone set to the interphone master set with a monitor. CONSTITUTION:In the interphone with a monitor having a doorphone slave set with a camera and an interphone master set 2 with a monitor 23, the master set 2 is provided with an interface circuit receiving a signal from the slave set and a signal from a trunk line, and the interface circuit and a telephone set 3 able to be used singly are connected by using a connector 27. The telephone set 3 is structured to be fitted to a recessed part 29 of the master set 2. In this case, since the interphone master set 2 with the monitor 23 has no multi-function telephone circuit, the cordless multi-function telephone set 3 is connected to the master set 2 through an exclusive modular connector 27 for speech line connection and a power supply pin jack 28. Thus, the interphone is used as the interphone having a monitor function.

Filed: 1995-12-07
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption by detecting the presence/absence of voice input from a microphone and stopping the operation of transmission circuit part when there is no voice. SOLUTION: A voice processing circuit 12 performs signal processing such as the code compression of voice inputted from a microphone and decomposition into frames. A modulation circuit 13 modulates the encoded voice to a signal suitable for radio transmission such as digital modulation and frequency conversion and transmits that signal through an amplifier circuit 14 and an antenna 15. A transmission control circuit 16 controls the modulation circuit 13 and the amplifier circuit 14 and each time a slot corresponding to a reception slot among the slots dividing a frame comes, transmission is intermittently performed.  In this case, a voice presence/absence detection circuit 17 detects whether any voice is inputted from the microphone 11 or not and when no voice is inputted, the operations of modulation circuit 13 and amplifier circuit 14 are stopped through the transmission control circuit 16.

Title: Gas leak detection method and device used therefor
Inventor: MACHINO AKIRA
IPC: G01M3/00
Filed: 1995-12-07
Abstract: PROBLEM TO BE SOLVED: To early and accurately detect gases leaking in soil by preparing a uniform mixed gas out of fuel gas and helium gas, and feeding the mixed gas to a main branch pipe for detecting the helium gas after the leak and diffusion thereof. SOLUTION: A flow rate ratio control circuit 11 calculates and outputs a helium gas flow rate ratio corresponding to the flow rate of LP gas, in response to a signal outputted from a gas meter 7. Also, an automatic flow rate adjuster 10 makes the adjustment of the flow rate of helium gas, so as to keep a constant flow rate ratio of LP gas to helium gas, depending on a signal outputted from the circuit 11. Thus, the flow rate ratio of LP gas to helium gas is controlled at a constant value, and both of the gases are evenly mixed with a stationary mixer 8. Furthermore, a gas mixing device mixes both gases to a constant value on the basis of the constant flow rate ratio, and a mixture of the gases is supplied to an LP gas main branch pipe 3. When the mixed gas leaks at a leak position on the main branch pipe 3 in soil, helium gas having a high diffusion rate is quickly diffused. As a result, the leak position can be early and accurately identified with a detection means on the ground.

Title: Electromotive solid breaking device
Inventor: KATAOKA AKIHISA
IPC: B60M3/00
Filed: 1992-11-30
Abstract: PURPOSE:To enlarge a capacity of the backward current without adding an expensive circuit element to the conventional circuit. CONSTITUTION:An electromotive solid breaking device lets the forward current flow through a semi-conductor breaking element as a forward element, and lets the recovery current flow through a diode 22 as a backward element and a switch 23 provided in series to the diode 22. During the time when the forward current flows, a current direction detector works an opening/closing operating means to open the switch 23 and block the flow of the forward current to the diode 22 side, and breaks the circuit at need with the semi-conductor element as a forward element 21. The forward current breaking characteristic is thereby maintained, and the forward current is maintained at a large value with the semi-conductor element as the forward element 21, and a current capacity of the backward current is made large by the diode 22 as a backward element.

Title: Hot air heater with function to deodorize
Inventor: SAKAI HIROAKI
IPC: F24F1/00
Filed: 1987-12-17
Abstract: PURPOSE:To enable a deodorant to be reused by a method wherein either a changing- over switch or a main switch is controlled by an air blowing port gas sensing device when the changing-over switch is at its normal rotating side and in turn by an air suction port gas sensing device when the changing-over switch is at its opposed rotating side. CONSTITUTION:When the main body of an equipment is operated, air passes from an air suction port 3 through a deodorant 7 and a heater 6 under a rotation of a fan 4. Hot air from which door is removed is blown from an air blowing port 2. After use, a main switch 8 is opened and even if an operation is stopped, a deodoring function is acted while the odor constitutes remain and a concentration of odor is detected by a gas sensing device 11 at an air blowing port 2. When its concentration is decreased lower than a predetermined value, an operation is automatically stopped. In this case,when a deodoring life of the deodorant is completed, a changing-over switch 9 is changed over to cause an air flow to be reversed and then air sucked from the air blowing port 2 is heated by a heater 6, then a deodoring and reproducing function for blowing air into the deodorant 7 is carried out. Then, the air blown from the air suction port 3 is detected by the gas sensing device 12 and when the concentration of the odor is less than a predetermined value, the operation is automatically stopped.
