Title: Internal cutting edge and manufacture thereof
Inventor: ONO TAKATOSHI
IPC: B24D5/12
Filed: 1988-02-08
Abstract: PURPOSE:To tense a cutting edge under uniform tension upon use so as to eliminate vibration of the cutting edge and strain thereof and to enhance the machining accuracy by forming a cutting edge forming plate and a base member from materials having linear expansion coefficients which are different from each other. CONSTITUTION:Since an internal cutting edge is used at a temperature higher than that upon electroplating of a cutting edge forming plate 5, both base bed 1 and the cutting edge forming plate 5 expand during a period from the time of the electroplating to the time of use. In this arrangement, the linear expansion coefficient of the base bed 1 is set to be greater than that of the cutting edge forming plate 5. Accordingly, the base bed 1 expands in comparison with the plate 5 which is therefore drawn radially outward by the base bed 1. As a result, the internal cutting edge 3 is automatically tensed upon use thereof, and no vibration of the cutting edge 3 occurs with no strain, thereby a semiconductor substrate or the like is precisely cut or grooved by the cutting edge 3.

Abstract: PURPOSE: To enable to accurately measure the surface potential of a material by  applying a DC voltage to a measuring electrode through an element having a high  resistance, whereby an offset voltage remaining in the measuring electrode can be  erased.  
     CONSTITUTION: When a chopper vane 103 is roated to open and close a potential detection bore 107, an electric field between a material 106 to be measured and a measuring electrode 104 is varied to generate an extremely small amount of AC voltage in the electrode. The amplitude of this AC voltage is proportional to the potential of the material 106. This AC voltage is converted into a low-impedance signal by a FET110, amplified to a desired value by an AC amplifier 112 and subjected to rectifying integration in a recticfier  integrating circuit 113. As a result, an output of a DC voltage in proportion to the potential of the material 106 are obtained. In the FET110, a gate voltage is kept positive by DC bias power source 118. Accordingly, an offset potential Eo remaining in the measuring electrode 104 can be erased so that the surface potential of the material 106 can be accurately measured.

IPC: D06F58/02
Filed: 1993-02-17
Abstract: PURPOSE:To prevent a hot wet air from being discharged into a room, and save a tap water for cooling by supplying a cooling water stored in a water tank to a heat exchanger by a feed water pump to cool and dehumidify a circulating air containing moisture, sending the circulating air into a cloth drying drum after heated through a heating heater, and returning the cooling water to the water tank. CONSTITUTION:When drying operation is started, a motor 2 is rotated, a drum 1 and a blowing fan 4 are rotated, and a current is also flowed to a heater 6. When a water tank 14 contains no cooling water or little cooling water, then, a determined quantity of tap water is supplied into the water tank 14 through a solenoid feed valve 15 by the detection of a level sensor. A cloth 23 makes contact with an air (c) heated through the heater 6 to partially evaporate the moisture, and the air (c) becomes a wet air (a). The air (a) makes contact with the cooling fin 10 of a heat exchanger 7 by the air blowing of the blowing fan 4. Since a cooling water 13 is sent to a cooling pipe 9 by the feed water pump and cooled in the heat exchanger 7, the wet air (a) becomes a cooled and dehumidified dry air (b).

Title: Vacuum cleaner for copying machine
Inventor: SUGITA YASUMI
IPC: G03G21/10
Filed: 1982-02-23
Abstract: PURPOSE:To remove toner clouds and to prevent the decrease in cleaning efficiency by regulating the vacuum pressure by a blower in response to the output of a sensor which detects the density of the solid black region in the test region of a photoreceptor. CONSTITUTION:A sensor 23 for density of solid black regions is disposed adjacently to a photoreceptor 1 on the upper stream side of a cleaning housing 10. The sensor 23 detects the density of the test region provided on the photoreceptor 1 and outputs an L signal when the density is lower than a reference signal. The output of the sensor 23 is fed to a control device 24 of  a copying machine. The device 24 controls a toner distributing roll 9 of a developing device and controls the operation of a blower 15. More specifically, when the sensor 23 outputs the L signal, the rotating speed of the roll 9 increases and the supply rate of the toner increases. At the same time, the input voltage to the blower 15 increases, thereby increasing the suction force for the toners. The toner clouds generated in the edge parts of the housing 10 are thus cleaned immediately. The decrease in cleaning efficiency is prevented.

Title: Voice synthesizer
Inventor: POORU ESU BURIIDORABU
IPC: G10L19/06
Filed: 1980-03-05
Abstract: A speech synthesis circuit is provided with a variable frame length data converter and the speech synthesizer is preferably integrated on an integrated circuit chips. The variable frame length data converter reduces the amount of data required to synthesizer human speech at a given quality level. Preferably, a full frame of data includes, a pitch parameter, an energy parameter, a repeat bit and a plurality of speech coefficients. Each parameter or coefficient has a preselected length, but each frame has a variable number of parameters or coefficients associated therewith. The parameters and coefficients are encoded and a particular code of the pitch parameter indicates that the speech is to be unvoiced. An unvoiced frame includes fewer coefficients that a voiced frame and the converter detects this particular pitch parameter and automatically sets the unsent coefficients to zero. The converter also detects the state of the repeat bit for controlling the synthesizing to use the coefficients received during the previous frame as the coefficient to be used to generate speech in response to the present frame. In this embodiment, when the repeat bit comes up, new pitch and energy parameters are inputted therewith. Further, the converters preferably detects particular codes in the energy parameter for determining when a pause occurs or when the last frame of data has been sent.
