Title: Semiconductor device
Inventor: NAKAGOME YOSHINOBU
IPC: H01L27/108
Filed: 1998-12-25
Abstract: PROBLEM TO BE SOLVED: To deal with various kinds of power supply voltages by providing an LSI block which has low power consumption mode suitable for battery backup to operate even with a low power supply voltage, a power supply voltage converting circuit for providing the internal power source just suitable for operation mode to LSI and an input/output circuit for converting signal amplitude. SOLUTION: In circuit blocks 60 and 61 operating with power supply voltages Vc11 and Vc12, the block 60 does not require operation at the time of holding information under the condition of Vc11=0 V and the block 61 requires the operation for holding information where Vc12 is constant independent of the type of the operation. Moreover, substrate bias voltages of N-channel and P- channel MOSFET-T32, T34 and T33, T35 of the circuit block 61 are VBN1 and VBP1. In order to operate the circuit until the power supply voltage Vc12 becomes almost 0.5 V, the substrate voltage is controlled and thereby the threshold voltage of the FET-T32 to T35 is changed in the direction to make more difficult to become conductive than that for the standard operation. Thereby, operation can be realized at a low voltage, low power consumption and high speed.

Title: Waterproof camera
Inventor: NANBU KOJI
IPC: G03B17/08
Filed: 1998-12-25
Abstract: PROBLEM TO BE SOLVED: To inexpensively provide a waterproof camera excellent in versatility and capable of anti-fogging it with a simple structure. SOLUTION: A waterproof film unit 2 with a lens is composed of a film unit 3 with a lens and a waterproof case 4 housing the unit 3. The front surface of the case 4 is provided with exposing parts for exposing a photographing lens and a finder. Then, thin parts 32a and 32b being thinner than the exposing part are formed at both side surfaces of the case 4. Because of that, when the unit 2 is carried underwater and the peripheral temperature of the case 4 is suddenly lowered, the temperature of the inside walls of the thin parts 32a and 32b are lowered earlier than that of the other part. Thus, moisture in air in the case 4 is concentrated at the thin parts 32a and 32b and it becomes dewdrops there. As the result, the moisture is reduced and the dewdrops are hard to be formed at the exposing part.
