Title: Semiconductor device
Inventor: OYA NOBUAKI
IPC: H05K3/34
Filed: 1995-04-18
Abstract: PURPOSE: To provide a semiconductor device against which whether or not bumps have been soldered in good states can be discriminated surely and easily. CONSTITUTION: Since soldering bumps 15 arranged in the state of a two-dimensional matrix on the surface of a wiring board 12 are constituted of tall bumps 15a having higher heights and short bumps 15b having lower heights and the short bumps 15b are arranged on the outermost periphery, it can be discriminated that the tall bumps 15a are sufficiently crushed and soldered parts are sufficiently stuck to the bumps 15a with prescribed large contacting areas when the low bumps 15b are sufficiently crushed and soldered parts are sufficiently stuck to the bumps 15b with prescribed contacting areas. Therefore, the soldering states of the tall bumps 15a can be estimated when the soldering states of the short bumps 15b arranged on the outside are visually confirmed.  Consequently, whether or not the parts are properly soldered to the bumps 15 can be discriminated surely and easily when the parts are mounted on the wiring board 12.

Title: Input buffer of low power supply voltage semiconductor device
Inventor: KIN TETSUSHIYU
IPC: H03K19/0175
Filed: 1996-04-15
Abstract: PROBLEM TO BE SOLVED: To prevent the malfunction of an input buffer by providing a power source transistor, a first load transistor, a second load transistor, a buffer means, and a by-pass transistor to quickly transit the output signal of the buffer. SOLUTION: When the reference voltage Vref of an input buffer is 1.4 V in a TLL-level state, the transistor M3 having a relatively low threshold voltage of the transistors M3 having a threshold voltage which is equal to the reference voltage Vref is turned on earlier than a transistor M2 and the potential at a node N2 becomes 'H' at the fall of input signals. At the rise of the input signals, the transistor M2 is turned on earlier than the transistor M3. Therefore, a second load transistor M5 constitutes a current mirror and is turned on and the potential at the node N2 gradually drops to an 'L' state. When the potential at the node N2 gradually drops, a by-pass transistor M6 quickly drops the potential at the node N2 to the 'L' state by making the charges stored in the node N2 to by-pass.

Title: Heat pump device
Inventor: NAKATANI KAZUO
IPC: F25B1/00
Filed: 1988-04-15
Abstract: PURPOSE:To reduce the amount of heat required for the separation of gas from liquid refrigerant due to the decrease in a heating rate when density reaches the desired level during the separation operation of the title device, and to shorten the separation time by increasing the heating rate when density does not reach the desired level, by providing a heater with a pipeline arranged between a compressor and a condenser CONSTITUTION:As a heater 12 is provided with a pipeline arranged between a compressor 11 and a condenser 13, the temperature of liquid refrigerant stored in a reservoir 17 is close to the outlet temperature of the condenser 13 and is relatively low in the initial period during a separation operation. On the other hand, the temperature of gas blown out of the compressor 11 and flowed into the heater 12 is high, and the temperature difference between the outlet gas and the stored liquid refrigerant becomes wide, and as a result, a beating rate becomes remarkably great. Consequently, the amount of gas generated increases to bring the gas into better contact with the liquid, thereby promoting the separation during the initial period. Further, when refrigerant with a high boiling point is accumulated within the reservoir 17 as separation proceeds, the boiling point becomes high, and accordingly, the temperature of the liquid is also raised. In accordance with this temperature rise, the temperature difference between the liquid and the gas blown out of the compressor 11 is also gradually made small to reduce a heating rate. When density reaches the desired level, the heating rate becomes substantially zero, and the separation is suspended with the density kept at the desired level.
