摘要:
To provide an inexpensive wastewater treatment method which facilitates downsizing of tanks and requires less withdrawal of an excessive sludge, the use is made of an aeration tank 1 in which wastewater is contacted with a particulate carrier under an aerobic condition, and a total oxidization tank 3 in which the volume of a sludge generated in the aeration tank 1 is reduced under an aerobic condition, a coefficient of self-oxidization of the sludge flowing into the total oxidization tank 3 is set to 0.05 (per day), and the method includes a step of adding a coagulant to the total oxidization tank 3 for the purpose of improving the solid-liquid separating characteristic of the sludge within the total oxidization tank.

A seat belt device allowing easy connection of a lap anchor fixed to one end of a seat belt relative to a vehicle body or the like even when a seat weight sensor is installed below a vehicle seat. The seat weight sensor and the vehicle seat are fixed to a vehicle body floor. A hitch member is attached to the seat weight sensor via a mounting bracket by a bolt. A lap anchor is fixed to one end of a seat belt. By locking the lap anchor to the hitch member, the seat belt is connected to the seat weight sensor. In this manner, the seat belt can be easily connected to the vehicle body just by locking the lap anchor to the hitch member.

A seat belt device includes a seat belt for restraining and protecting an occupant sitting on a vehicle seat; a lap anchor fixed to an end of the seat; seat weight sensor installed below the vehicle seat for measuring a seat load; and a hitch member including two ends and a slide bar therebetween. The seat weight sensor and the vehicle seat are fixed to a vehicle body floor. One end of the hitch member is attached to one of the vehicle body, the vehicle seat fixed to the vehicle body, or the seat weight sensor fixed to the vehicle body. A second end of the hitch member is fixed to the vehicle body. The lap anchor is slidably attached to the slide bar.
摘要:
A liquid crystal panel in which temperature rise of the liquid crystal panel is sufficiently restrained by cooling the panel by means of a cooling liquid, and exudation of the cooling liquid toward the liquid crystal material is prevented. Disclosed are cover members attached to the liquid crystal panel that form cavities on the light entrance and exit sides of the panel. The cover members are such that a sealed portion of the liquid crystal material is not in contact with the cavities. The cover members are light transmitting. The cavities are filled with the cooling liquid.

A seat weight measuring apparatus includes a support body one end of which is fixed in position relative to a vehicle body and the other end of which is displaced corresponding to a load from a vehicle seat side. The apparatus includes a permanent magnet which is disposed at one end of the support body and a held body which has a shape retaining property and is held by the other end of the support body, and a detector which is disposed on a tip of the held body to face the permanent magnet with a space therebetween.

A self-sustained pulsating laser diode in which a region in an active layer functions as a saturable absorber has at least five and no more than ten quantum wells, p-type cladding layer flat part with a layer thickness of at least 300 nm and no greater than 500 nm, and a p-type cladding layer flat part with a carrier density of at least 1×1017 cm−3 and no greater than 5×1017 cm−3. This laser diode achieves a sufficiently small current distribution compared with the light distribution in the lateral direction, thereby enabling stable self-sustained pulsating operation up to a high temperature, which was difficult to achieve in the past.

摘要:
A seat belt retractor for retracting a seat belt is formed of a first motor for retracting a seat belt with a force not providing a pressing feeling to a passenger, a second motor having a torque greater than that of the first motor for retracting the seat belt with a force forcibly holding the passenger to a seat, and a control circuit connected to the first and second motors for controlling the same. Thus, the seat belt retractor can perform a forced retraction and a normal retraction with an economical structure.

A vehicle collision damage reduction system is provided. The system works by detecting the relative speed between the vehicle and an object, such as another vehicle. A danger level is calculated based on parameters such as speed and distance to the object; the danger level could be at an “emergency level” or at some lower level. Based on the danger level, different corrective measures and the degree of the corrective measures can be adjusted to attempt to minimize occupant injury. For example, the airbag can be adjusted to better protect the occupant, a pre-tensioner can be activated at a certain level, and the inclination of a child restraint seat may be adjusted as well.

There is provided a semiconductor device including (a) a semiconductor substrate on which an integrated circuit is formed, (b) a ground electrode formed on the semiconductor substrate, (c) a bonding wire through which the ground electrode is grounded, the bonding wire having inductance, and (d) a capacitor positioned in series with the inductance, the capacitor and the inductance cooperating with each other to form a resonance circuit at an operating frequency of the integrated circuit. For instance, the capacitor is comprised of a lower electrode formed on or above the semiconductor substrate, an insulating film covering the lower electrode therewith, and an upper electrode formed on the insulating film above the lower electrode. The provided semiconductor device reduces noises and saves power.
摘要:
In a method of manufacturing a semiconductor laser device having a double hetero structure which is structured by at least a first clad layer, an active layer and a second clad layer on a semiconductor substrate by the use of the organic metal vapor growth method, crystal is grown in first atmosphere gas containing hydrogen in a temperature rising process. Subsequently, the first atmosphere gas is switched into second atmosphere gas in a temperature dropping process after the crystal growth. The second atmosphere gas contains no hydrogen.
