A semiconductor layer 1 is made of a metal, an intrinsic semiconductor are an n-type semiconductor, a p-type semiconductor, an intrinsic semiconductor and an n-type semiconductor or the like on the film 2. An electrode 4 is fitted on the layer 1. An electromotive force caused by irraidating light 5 upon the exposed face of the substrate 3 is picked out through the layer 2 and the electrode 4. A photoelectric converter is thus manufactured. Minute recesses and projections are previously provided on the semiconductor layer coated face of the substrate. A flexible substrate made of polyimide resin may be used as necessary. The semiconductor layer is made of non-single crystal. This results in making the photoelectric converter appropriate in manufacturing a timepiece or the like.

Title: Developing device
Inventor: OKADA YUJI
IPC: G03G15/08
Filed: 1993-02-10
Abstract: PURPOSE:To supply toner which has already been electrified and is hardly flocculated and hardly incorporated with impurities, to develop an electrostatic latent image holding member and to obtain a sharp image without fogging, under-and over-development by providing a toner filter for allowing the toner to pass. CONSTITUTION:The toner housed in a casing 2 is supplied onto the toner filter 3 and passes therethrough by the action of gravity, but a thing caught on a layer regulating member 6 out of the impurities mixed with the toner stored in the casing 2 and exerting adverse influence on the formation of a toner layer is removed from the toner without passing the toner filter 3. For making the passage of the toner on the toner filter 3 more smooth, a rotary body 4 is abutted on the toner accumulated on the toner filter 3 and rotated. Pressure is imparted to the toner by the rotation of the rotary body 4, so that a sufficient quantity of the toner for developing the electrostatic latent image holding member 5 passes the toner filter 3 and the sharp image without the scattering of the toner and the underdevelopment can be obtained.

Title: Chain type power transmitting belt
Inventor: TAKANO HIROSHI
IPC: F16G5/18
Filed: 1989-01-30
Abstract: PURPOSE:To reduce a noise generated by a colliding sound and by friction of a chip unit with a V-pulley wall surface, when a belt is in running, by forming the chip unit having a cone-shaped or truncated cone-shaped end face and the chip unit providing two or more grooves to be engraved in said end face. CONSTITUTION:A pin 30 is protruded from an outer wall 12 of an outer link plate outside a belt 1, and the pin 30 fits to its both end parts a chip unit 40 engaging with a wall surface of a V-pulley bringing into contact with its wall surface an end face providing two or more grooves 41. As the result, the groove 41 serves as a passage of oil, and the oil in the groove 41 is always supplied to the end face coming into contact with the pulley wall surface, suitably holding an oil amount between the chip unit 40 and the pulley wall surface, maintaining a coefficient of friction in a boundary surface to a high level and impeding a slip sound of the belt 1. While the chip unit 40 comes into contact with the pulley wall surface in a ridge line further generates irregularity, by adding rotation, in a collision condition or pitch with the pulley wall surface, thus with a colliding sound easily generating its interference, and a noise is reduced.

Filed: 1982-02-15
Abstract: PURPOSE:To produce steel plates of excellent shapes having target crowns in a rolling mill provided with an automatic control device of a gage meter system for thickness and a roll bender by separating the mutual interference of the thickness control and the shape control. CONSTITUTION:The rolling reaction in the stage of rolling a steel plate 1 with work rolls 2 is detected with a detector 6 for rolling down force, and the manipulated variable corresponding to the difference between said reaction and the reference rolling reaction for the purpose of making the thickness on the outlet side of the plate 1 constant is calculated with an arithmetic device 10 and is outputted to a servocontrol valve 9a.

Filed: 1981-02-20
Abstract: PURPOSE:To achieve high-precision and high-fidelity reproduction without spoiling the characteristics of PCM by installing a coil assembly in a magnetic gap, and powering up a corresponding number of coils in a specified direction by operating switching elements on the basis of a PCM signal. CONSTITUTION:In the magnetic gap G of a magnetic circuit, a coil assembly 5 provided to a bobbin 4 is installed, and the bobbin 4 has many unit integrated elements each consisting of a unit coil 5' and transistors (TR) Q1 and Q4. Those TRs Q1-Q4 operate as switching elements; when a signal appears on a signal line 21a, the TRs Q1 and Q3 turn on and when on a signal line 21b, the TRs Q2 and Q4 turn on. Therefore, the feeding direction of the coil 5' is determined by the signals on the signal lines 21a and 21b. A microporcessor 9 decodes a PCM signal to generate a signal to be applied to the switching elements of the unit elements whose number corresponds to the signal, thereby powering up the coil 5' in a direction which correspond to the polarity. Therefore, the coil 5' operates in the gap G to radiate a sound from a diaphragm 6.

IPC: F16D65/092
Filed: 1998-02-04
Abstract: PROBLEM TO BE SOLVED: To easily change the vibration characteristic of a back plate by laminating a plurality of plates, and integrally fixing them at a plurality of parts. SOLUTION: In a stainless steel back plate 36 integrally fixed to the back side of friction material 34, four plates 38, 40, 42, 44 with specified thickness are laminated in a direction of plate thickness and partially fixed to each other by positioning press-in rugged parts 46 in four places and rivets 47 in two places, and the plates 38, 40, 42, 44 are respectively vibrated at parts not integrally fixed to each other by the positioning press-in rugged parts 46 or rivets 47, thus improving vibration damping performance at the time of braking. A vibration characteristic such as resonance frequency and a vibration mode can be easily changed by changing the number of positions of the parts integrally fixed to each other by the positioning press-in rugged parts 46.  Resonance and the like can therefore be effectively reduced on the basis of the vibration characteristic or the like at the time of braking.

Title: Rotary type compressor
Inventor: KOYAMA TAKASHI
IPC: F04B39/12
Filed: 1984-02-09
Abstract: PURPOSE:To prevent the vibration of a discharge cover due to the pulsation of the discharged coolant by installing a discharge cover through a partitioning plate having a small hole formed onto the counter-cylinder surface of a bearing and forming a nearly conical projection at the part opposed to the small hole on the discharge cover. CONSTITUTION:The coolant compressed in a cylinder 7 is discharged into a valve chamber from a valve hole and further jetted into an expansion chamber 12a from a small passage and discharged into a discharge chamber 16a from a small hole 15. The coolant discharged from the small hole 15 transforms its form from a straight-line flow to an eddy current flow, since a projection 17 is formed onto a discharge cover 16, and the coolant collides with the discharge cover 16 at an acute angle. Therefore, even if the discharged coolant possesses a pulsation component, the discharge cover 16 is prevented from vibration.

The shaft 43 whose resistance with respect to bending is large is started to be bent from the more tip end side and the bending start position of the sleeve 42 whose resistance with respect to the bending is small and which is more flexibly bent is set at a more base end side. Besides, the shaft 43 is previously bent to a certain extent at the position where the sleeve 42 is started to be bent.
