The printed circuit board comprises a substrate 1 including a part loading portion 3 into which an electronic part 5 can be loaded, a plurality of contact terminals 2 which are respectively formed on one surface of the substrate 1 and the surfaces of which are exposed to the outside to provide external contacts, and openings 4 respectively formed in the other surface of the substrate 1 for insertion of bonding wires 6 which are used to connect the electronic part 5, which are to be loaded into the part loading portion 3 of the substrate 1, to its associated contact terminals 2. In the printed circuit board, each of the contact terminals 2 is formed of a metal foil 9 directly and closely attached to the substrate 1. This can prevent the lowered heat resistance of a printed circuit board which occurs when the metal foil, which is used to form the contact terminals 2, is bonded to the substrate 1 using an adhesive.

The wiper blade according to the present invention consists of a blade lever and a wiping string held as extended tight on one side of the blade lever. The height of the wiper blade is a maximum of a sum of a thickness of plate-like blade lever, outside diameter of the wiping string and the spacing between the blade lever and wiping string. The width of the wiper blade is that of the blade lever. Therefore, the wiper blade can be designed small as a whole. The mirror holder has formed thereon a wiper blade guide consisting of as ascending slope to lift away from the mirror surface the wiper blade having been moved to near its reverse position and a vertical wall to land the wiper blade, having been thus lifted and reversed, from the lifted position above the mirror surface onto the mirror surface to a predetermined position where the wiper blade starts being moved back. Thus, the wiper blade can jump over a rainwater it has gathered by its forward movement and wipes it again along with new raindrops by its reverse movement with no trailing, during the reverse movement, of the rainwater having been gathered downward once by the forward movement, thereby permitting to effectively wipe away raindrops on the mirror surface.

A simulator for simulating operations of a logical circuit has as its object the provision of a simulator capable of detailed timing error checking without impairing the simulation executing speed. A timing check primitive adding circuit, based on circuit information indicating electronic devices and loop circuits selected for timing error checking, outputs circuit information with simulation control data for controlling the simulation of only the selected devices or selected loop circuits. A timing error detection circuit and a timing error cause analyzing circuit grasp changes in test pattern input and output signals of a selected device and perform detailed timing error checking.

A semiconductor memory device is highly integrated by a combination of planer cell structure with the trench etching technique. Trenches are formed on a substrate in parallel with each other, and diffused layers are on sidewalls of the trenches to provide bit lines. Gates oxide layers are formed on the bottoms of trenches and on surfaces of the substrate between adjacent two trenches, and silicon oxide layers thicker than the gate oxide layers are on the bit lines. Word lines are formed in band in parallel with each other in a direction to cross the trenches perpendicularly thereto. Channel regions are defined in portions of word lines on the bottoms of trenches and on the surfaces of substrate crossed thereby. Ion implantation is conducted into each memory transistor according to data to determine a ROM code, to set a threshold value therein.

The cosmetic composition of this is an ultraviolet ray-absorbing cosmetic composition containing particles of cyclic imino ester which is excellent in ultraviolet ray absorbability, stable against water, sparingly soluble in organic solvents, fats and oils, sebum, etc., and further has only a low skin-irritating property. When this cosmetic composition is applied onto the skin, erythema is not formed on/in the skin even if it is exposed to sunlight for a long period, and further aging of the skin can be prevented.

The etch rate of phosphosilicate glass becomes lowered as boron ions are implanted therein. In accordance with the principle of the present invention, boron ions are implanted into a phosphosilicate glass film selectively in location or concentration and the thus boron-implanted phosphosilicate glass film is etched by an etchant, for example buffered hydrofluoric acid solution, to etch an intended portion of the phosphosilcate glass film preferentially thereby defining a hole, such as a contact hole, or substantially flat surface.

A suede-like raised woven fabric which comprises: warp yarns; weft yarns, each being a single twist filament yarn or a loopy textured filament yarn consisting of a bundle of fine fibers; and an elastic polymer applied to the fabric. The bundle of fine fibers consists of a raised portion having an average monofilament denier of from 0.05 to 0.4 and an unraised portion having an average monofilament denier of above 0.4 but not exceeding 0.8. The raised woven fabric is prepared by weaving a fabric using as weft yarn a single twist filament yarn or a loopy textured filament yarn comprising hollow composite fibers, each composed of at least four alternately arranged components of fiber-forming polyester and fiber-forming polyamide which are mutually adhered side-by-side encompassing a hollow space and extend along the longitudinal axis of the fiber to form a tubular body, and dividing the hollow composite fibers into fine fibers to form a bundle of fine fibers consisting of raised and unraised portions by a raising operation. The raised woven fabric has a high density and excellent uniformity of the raised fine fibers, and has excellent suppleness, surface abrasion and pilling resistances.

A hermetic electric compressor includes a motor unit having a stator coil and a compressor unit driven by the motor unit for compressing refrigerant gas. A temperature sensor is provided at the stator coil for monitoring a temperature of the stator coil. A control unit is further provided to control a rotational frequency or speed of the motor unit via the stator coil depending on the monitored temperature of the stator coil. The temperature sensor and the control unit are connected via a shielded cable or a twisted pair. The shielded cable or the twisted pair may be grounded via a capacitor. Further, a thermostat may also be provided at the stator coil and connected in series to the temperature sensor.

A first heat exchanger implements heat exchange between refrigerant and atmosphere. A second heat exchanger implements heat exchange between the refrigerant and air directed to an interior of the vehicle. A third heat exchanger downstream of the second heat exchanger implements heat exchange between the refrigerant and the air directed to the interior of the vehicle. A four-way valve connected among a refrigerant flow restricting device, the first heat exchanger, the second heat exchanger, and the third heat exchanger for changing a flow path of the refrigerant. A bypass device allows the refrigerant to selectively flow through the second heat exchanger and bypass the second heat exchanger. During a first mode of operation, the refrigerant is circulated sequentially through a compressor, the third heat exchanger, the four-way valve, the first heat exchanger, the refrigerant flow restricting device, the four-way valve, the second heat exchanger, and the compressor. During a second mode of operation, the refrigerant is circulated sequentially through the compressor, the third heat exchanger, the four-way valve, the refrigerant flow restricting device, the first heat exchanger, the four-way valve, the second heat exchanger, and the compressor. During a third mode of operation, the refrigerant is circulated sequentially through the compressor, the third heat exchanger, the four-way valve, the refrigerant flow restricting device, the first heat exchanger, the four-way valve, and the compressor while being allowed by the bypass device to bypass the second heat exchanger.
