Title: Stroboscopic device
Inventor: NAKAJIMA YUKIO
IPC: H04N5/232
Filed: 1996-04-04
Abstract: PROBLEM TO BE SOLVED: To eliminate the need of a dedicated control circuit including a light receiving element controlling emitted light quantity, to prevent preliminary light emission from flickering and to accurately control the emitted light quantity. SOLUTION: This device is applied to an electronic camera. The preliminary light emission is received by an image pickup element 1 in order to set the light quantity of main light emission. Based on a signal from the element 1, the light quantity of the main light emission is set and a timewise interval between the preliminary light emission and the main light emission is set so that the fluctuation in luminance cannot be recognized by a photographer and the like. When the temporal interval is over the set time, the flicker of the light emission being the sense of incongruity is prevented from being given to the photographer by executing light emission unrelated to the set of the light quantity of the main light emission once or more between the preliminary light emission and the main light emission.

Title: Production of artificial graphite
Inventor: ADACHI MASAKAZU
IPC: C04B35/52
Filed: 1983-05-11
Abstract: PURPOSE:To reduce the electrical resistance across contact surfaces and reduce remarkably power consumption, by inserting graphite sheets between contact surfaces of electrodes for electric conduction and primary calcined materials and/or contact surfaces between mutual primary calcined materials, and passing an electric current therethrough. CONSTITUTION:Natural graphite grains (preferably scaly graphite having large particle size as much as possible) are dipped in a strongly oxidizing solution, preferably at (1/3)-(1/10) molar ratio between an oxidizing agent and an acid, e.g. a mixed solution of concentrated sulfuric acid and concentrated nitric acid, washed with water and heated at about 900 deg.C to give swellable graphite powder, which is then formed into graphite sheets 5. The resultant graphite sheets 5 are then inserted between contact surfaces of electrodes 4 for electric conduction and primary calcined materials 2 and/or contact surfaces of the mutual primary calcined materials 2 and 2, and an electric current is passed through the electrodes 4. Thus, the electrical resistance between the contact surfaces is reduced to pass the electric current stably and reduce remarkably the power consumption. There is no fear of damaging the primary calcined materials 2 due to the partial intense heat generated between the contact surfaces.

Title: Charger and charging method
Inventor: KOIKE YASUHIRO
IPC: H02J7/10
Filed: 1994-04-22
Abstract: PURPOSE:To fully charge a battery positively by charging based on the states of the battery when the charging procedure is stopped before and when the charging procedure is started this time. CONSTITUTION:In the case of a two stage constant current charging system, an EEPROM 15 stores information representing charging with a constant current I1, or I2 and information representing the time for charging with the constant current I2, as a data relating to the charging state, while updating every minute. When the charging operation is resumed, a CPU 12 reads out the data from the EEPROM 15 and compares the battery voltage with a reference voltage upon elapse of a predetermined time. When the battery voltage is higher than the reference voltage, a decision is made that the battery 20 has not changed the state when the charging procedure is interrupted and the battery is charged with the constant current otherwise a decision is made that the battery 20 has changed the state and the battery is charged with the constant current I1. This method fully charges the battery positively.
