An ink jet recording head is produced by forming in a first substrate a plurality of orifices for ejecting an ink droplet and a reference object for registration; forming in a second substrate ejection energy generating elements for supplying energy for ejecting the ink placed in liquid passages communicating with the orifices; and joining the first substrate and the second substrate together on the basis of the reference object for registration.

A flashlight control apparatus having a device for emitting flashlight towards a subject and a device for receiving the light reflected from the subject through a photographing lens. An output is generated which corresponds to the received light which is time-integrated in order to calculate the amount of light received. An optimum integration level is calculated which is to be integrated. This optimum integration level corresponds to an optimum quantity of flashlight to be emitted by the emitting means, based on film speed information. A time limit is also calculated, which is shorter, by a predetermined length of time, than an optimum emission time of the emitting device. This optimum emission time is based on aperture value information and object distance information. The emitting device is controlled to stop emitting flashlight when the time limit elapses, in the case where a quantity of light received by the light receiving devices has reached an optimum quantity before the time limit elapses.

A storage battery-based DC power supply system with continuous float charging adapted to automatic continuous recharging of storage battery connected to load is disclosed. Selective recharging at the full-charge voltage and float charging voltage is performed in response to the accumulated ampere-hour value of discharge current from the storage battery, when such value reaches a predetermined threshold value set to prevent excessive recharging, which can damage storage battery.
摘要:
A light-quantity control device having a light-quantity control member which moves to change an aperture opening amount. A drive source swings the light-quantity control member in one direction and a spring having a coil part urges the light-quantity control member against the swinging direction of the drive source. A base member having an aperture fixedly supports the drive source and swingably supports the light-quantity control member. The base member has a shaft for carrying the coil part of the spring. The shaft is formed at a position outside the supporting position of the drive source on the base member relative to the center of the aperture.
摘要:
A mobile station sends a speech signal to a radio base station or, in the absence of speech signals, sends back a sync signal from the radio base station. The radio base station detects whether the signal received from the mobile station is a speech signal or the sync signal it sent. If a speech signal is received, it performs usual processing for speech signals or, if the sync signal is received, judges the line quality according to this sync signal.
摘要:
In an exhaust silencing device having inner tubes which are connected to an exhaust pipe connected to an engine and provided with a plurality of through holes, and an outer tube which covers the inner tubes. The occurrence of a whistling sound is prevented while avoiding the use of a sound absorbing material. Recesses are provided on the inner surface of the inner tube, which, together with the outer tube, form an annular expansion chamber.
