Title: Speaker system
Inventor: SASAKI MASAAKI
IPC: H04R1/02
Filed: 1987-02-23
Abstract: PURPOSE:To reproduce a sense of rich low-pitched sound by attaching a cover, which is projected at a prescribed height from the outside surface of a rear face of a speaker cabinet and has sound release holes in the peripheral part and has a U-shaped section, to the outside surface of the rear face of the speaker cabinet so that the cover protects the speaker unit having no drivers. CONSTITUTION:A cover 9 is formed so as to have a U-shaped section, and sound release holes 9a are provided on its peripheral wall and sound release holes 9b are provided on the wall surface facing a drone cone 8. When a speaker cabinet 1 is arranged on bow window, a chest, or the like and the rear face is brought into contact with the wall surface, the wall surface provided with sound release holes 9b of the cover 9 and a speaker terminal 11 are brought into contact with the rear face wall of the bow window glass, the chest, or the like. However, a space is formed between the cover 9 and the rear face wall of the bow window glass, the chest, or the like because the cover 9 has a U-shaped section and has a prescribed projection height, and sound release holes 9a provided on the peripheral wall of the cover 9 are not closed. Consequently, sound emission from the drone cone is not intercepted and sound are emitted to the outside to reproduce a sense of rich low-pitched sound.

Patent JP-S59165484-A (JP)
Title: Semiconductor laser
Inventor: ONABE KENTAROU
IPC: H01S5/32
Filed: 1983-03-10
Abstract: PURPOSE:To enable a low temperature growth and to facilitate the control of a composition by respectively composing a substrate, the first clad layer, an active layer, and the second clad layer of InP, In1-XGaXP, In1-ZGaZAs and In1-X'GaX'P, and varying the composition ratio (x) of the first clad layer to substantially match the grating constants. CONSTITUTION:An n type or p type active layer 8 is formed of a 3-element mixed crystal In0.38Ga0.62As represented at a point B. The point B is equal in its band gap energy to the composition of a point A, but grating constant alphao is different, and alphao=5.80Angstrom . The point B does not belong to a mixed unstable region even at low temperature such as 500 deg.C. A 3-element mixed In0.84Ga0.16P represented at a point C having the same grating constant as the point B is used as a P type clad layer 9 grown next to the layer 8. A layer continuously varied in composition between InP and In0.84Ga0.16P (the point C) is used as the n type clad layer 7 adjacent to an InP substrate 1, and the gratings are substantially matched between the boundary to the substrate 1 and the boundary to the layer 8. The formation of such composition varying layer can be readily performed by a vapor phase growth method.

Title: Transponder for discrimination of moving body
Inventor: MISAIZU KIMIHIDE
IPC: G01S13/79
Filed: 1989-02-20
Abstract: PURPOSE:To make an apparatus small in size and to reduce power consumption by modulating a signal of a microwave band from an interrogating device by one diode and by breaking a power source of an unnecessary circuit outside an emission area of the signal of the microwave band. CONSTITUTION:A control element 9 of a transponder is ordinarily out of operation, and when the transponder approaches a service area of an interrogating device, a microwave transmitted from the inerrogating device and received by an antenna 1 is detected by a diode 4. When a detection output thereof exceeds a prescribed value, the control element 9 is started and put in a state of operation. The antenna 1 and a modulator 10 are in matched states at this time, the microwave is taken in efficiently from the antenna 1, and the detection sensitivity of the diode 4 can be made high. In the service area, the transponder impresses a non-bias or reverse-bias voltage on the diode 4 through a diode 7 in accordance with internal data of the control element 9. When the reverse- bias voltage is impressed, the modulator 10 is put in a state of mismatch in impedance with the antenna 1 and a microwave signal is reflected totally by the antenna 1.

Title: Fuel injection pump
Inventor: INADA YOSHINOBU
IPC: F02M59/26
Filed: 1993-03-01
Abstract: PURPOSE:To provide a fuel injection pump which can reduce errosion of a wall surface of a fuel chamber or a spill protector which protects the wall surface. CONSTITUTION:When a plunger 3 is lifted, a plunger lead 31 of the plunger 3 is communicated with a feed hole 22. Fuel inside a plunger chamber 21 showing spill flow is returned to a fuel chamber 11 through the plunger lead 31 and the feed hole 22 with high speed. A volume of a suction chamber 23 below the plunger 3 is increased by lifting the plunger 3. The pressure inside the suction chamber 23 is lowered, and a part of the fuel flowed into the feed hole 22 from the plunger lead 31 is suctioned into the suction chamber 23 through a suction hole 29. As a result, an amount and kinetic energy of the spill fuel injected to an inner wall 11a of the fuel chamber 11 from the feed hole 22 are decreased, and the errosion thereof is decreased.

Title: Photoelectric conversion device
Inventor: ITO HARUO
IPC: H01L31/04
Filed: 1987-02-25
Abstract: PURPOSE:To obtain a photoelectric conversion device, which can recognize the pattern of projected light and radiation intensity distribution, by arranging two or more kinds of photovoltaic elements having the different spectral sensitivity characteristics. CONSTITUTION:Two kinds of photovoltaic elements 10, 20, 30 and 100, 200, 300, which have different spectral sensitivity characteristics 70 and 80 and indicate almost equal J-V characteristics under the projection of white light, are connected as shown in the Figure. At this time, when the white light is projected, the electric output is very small. When the light having the spectral intensity of 50 is projected, the large output is obtained. When the light having the spectral intensity of 60 is projected, the large output in reverse polarity is obtained. Thus the intensities of a plurality of the input lights having the different radiation intensity wavelength distributions can be simply compared with each other.

Concretely, first of all, the continuous form 1 are installed so that the fold 2 is situated ahead the positioning mark by a proper distance apart. Then tractors 5 are driven so as to move the continuous form 1. And the driving of the tractors 5 is stopped when the fold 2 and the positioning mark 3 fall into line with each other. In addition, since the positioning mark 3 sets apart from a printing line 8, on which printing is performed actually, by the distance L, a printing position is corrected by a program for executing the start of printing under the condition that this distance L is stored.
