IPC: G03B13/06
Filed: 1999-07-15
Abstract: PROBLEM TO BE SOLVED: To obtain an inexpensive compact finder device without increasing the number of component lenses by giving a function as a protection cover glass to a lens nearest to an object side and a lens nearest to an eye side in a finder optical system in order to protect an optical surface from damage and dust. SOLUTION: This camera is separately equipped with a photographing optical system and the finder optical system 3. The optical system 3 is provided with an objective optical system and an ocular optical system in order from an object side, and the lens (plano-concave lens) 11 on the object side of the objective optical system and the lens (plano-convex lens) 32 of the ocular optical system nearest to the eye side are fixed to be nearly the same plane as the outside case 4 of the camera, and function as a protection cover protecting an optical device inside the optical system 3. Since the object-side lens surface of the lens 11 and the eye-side lens surface of the lens 32 are always put in environment where they are easily damaged as the protection cover glass, it is desirable to apply surface treatment such as protective coating to them for the purpose of the prevention of damage.

Title: Regulator device for battery
Inventor: TAKEUCHI KIYOSHI
IPC: F02B37/00
Filed: 1990-07-30
Abstract: PURPOSE:To enable execution of charging by a boosting control even when the voltage of an output from a power generating mechanism such as a rotary electric machine is low and a battery can not be charged generally, by boosting the output voltage from the power generating mechanism obtaining a power from collected exhaust energy, by using an induction regulator. CONSTITUTION:When exhaust energy is small and a turbo-charger 1 rotates at a low speed, the speed of rotation of a rotary electric machine 2 turns low and a voltage outputted therefrom turns low, e.g. 12V or below. In this case, a controller 6 gives a boosting instruction to an induction regulator 3 so as to boost an output voltage to (12+alpha)V to be obtained by adding a prescribed voltage alphaV thereto. Therefore, a small but boosted generated power is supplied to a battery 5 through a regulator 4, so as to charge the battery. When the output of the rotary electric machine 2 is large due to a high-speed rotation, in other words, it is lowered to a voltage being appropriate for charging the battery 5, and when a generated voltage is low due to a low-speed rotation, the output is boosted.

Title: Light-receiving position detection circuit
Inventor: YOSHITOMI TETSUYA
IPC: G01C3/06
Filed: 1997-07-28
Abstract: PROBLEM TO BE SOLVED: To detect a light-receiving position stably with high precision. SOLUTION: A light-receiving position detection circuit has a light-receiving unit 10 consisting of (n) PDs(photodiodes) which are arranged in parallel with each other and detects a light-receiving position in the light-receiving unit 10, by comparing the magnitudes of the photocurrent detection outouts of the adjacent two PDs with each other. A 1st amplifier 16 amplifies the output of PDn-1 baged on a 1st reference voltage Vref1. A 2nd amplifier 18 amplifies the output of PDn based on a 2nd reference voltage Vref2. A comparator 22 compares the output of the 1st amplifier and the output of the 2nd amplifier with each other.  By setting the reference voltages to satisfy a relation Vref1>Vref2, if the light-receiving levels of PDn-1 and PDn are identical to each other or lower than a predetermined level, the comparator 22 outputs a comparison result such that the light-receiving level of the PDn side is larger. Furthermore, by providing a limiting resistor 20 on the output side of the 2nd amplifier 18 to limit an output level, when the light-receiving level is excessive, the comparator 22 outputs a comparison result such that the light-receiving level of the PDn-1 side is larger. With this constitution, a stable discriminating result can be obtained corresponding to the light-receiving level.

Title: Plate type heat pipe and cooling structure using the same
Inventor: IKEDA MASASHI
IPC: F28D15/02
Filed: 1998-07-17
Abstract: PROBLEM TO BE SOLVED: To maintain performance of certain degree in a top heat mode by extending a wick member partly brought into contact with a heat radiating side main surface wall along a heat transfer block to a heat absorbing side main surface wall, and forming an end of the member brought into contact with the heat absorbing side main surface wall in a substantially flatly aligned state. SOLUTION: In the case that the plate type heat pipe 10 is inverted or largely inclined a circulation of a condensed working fluid by its gravity operation cannot be expected. In such a case, a wick member 30 is extended to a heat absorbing side main surface wall 1000 along the block 20, and the condensed fluid is circulated by a capillarity of the member 30. Further, since an end of the member 30 is brought into contact with the wall 1000 in the state that it is substantially flatly aligned, the fluid moved by the capillarity is more effectively arrived at the wall 1000.

IPC: G10H1/18
Filed: 1981-12-15
Abstract: PURPOSE:To provide a prescribed effect to a time division multiplexed signal without performing complicated circuit switching, by storing temorarily the time division multiplexed signal and then reading out said multiplexed signal by exchanging the order of time division multiplexing. CONSTITUTION:The time division multiplexed signal is applied to a terminal DI of a storage device 1. This signal is written when the R/W signal applied to a terminal R/W is written and then read out when the R/W signal is read out. While a clock signal CL is applied to an address generator 3 to produce the 1st address code AD1. This code AD1 is applied to a selector 2 as well as to an address converter 4. The converter 4 converts the code AD1 into the 2nd address code AD2 in response to the selection signal. The code AD2 is applied to the selector 2. Then the time division multiplexing order is exchanged with the address AD selected at the selector 2, and the signal written into the device 1 is read out to a modulator 5. The selection signals applied to the converter 4 are switched in accordance with the selection of the effect of an electronic musical instrument.

Title: Square root(f) automatic gain control equalizer
Inventor: TANIGUCHI KIYOSHI
IPC: H04B3/06
Filed: 1985-09-13
Abstract: PURPOSE:To prevent the generation of noise even when a capacitor giving gradient is switched by giving a potential to the capacitor giving the gradient even not in use while being switched by the switch of a gradient gain circuit. CONSTITUTION:Switches SW3, SW4 are provided and a switch SW2 is turned on by, e.g., a control signal, then the switch SW4 is turned off via a NOT circuit 2 and when the switch SW1 is turned off, the switch SW3 is turned on via a NOT circuit 2. Thus, since a voltage between a reference voltage Vref and a potential at a point A is applied to a capacitor, e.g., C1 not in use via the switch SW3, even when the capacitor C1 is used by turning on the switch SW1, the capacitor C1 is not charged, thereby no impedance change is caused nor noise is generated.
