Title: Standard spacer
Inventor: HIRANO YUKIO
IPC: B25H7/00
Filed: 1994-02-03
Abstract: PURPOSE:To easily and precisely perform a die fitting by fixing or connecting a number of standard blocks formed by rolling a soft nonelastic material into a bar or small ball to a sheet or cord consisting of paper, resin or cloth. CONSTITUTION:Standard blocks 1 of a soft metal such as solder, copper or aluminium having a bar form thicker than the necessary clearance of dies are adhered and fixed to a thin sheet 2. Since a standard spacer having the standard blocks 1 fixed to the sheet 2 is put between the clearance between an upper die 5 and a lower die 6 to perform the die fitting, the dies are never flawed nor dented, and the standard blocks 1 are dented to the dimension of the clearance when the dies are fitted to each other. Since holes 3 are bored in a part of the standard blocks 1, the thickness of the standard blocks 1 in this part is equal to the clearance of the dies. Since the clearance of the dies in this part can be determined by measuring this dimension of the standard, rough finishing is then carried out. Thus, the fitting between the dies 5, 6 can be easily and precisely performed.
Patent JP-H02220623-A (JP)
Title: Vacuum cleaner
Inventor: ISHII SEIJI
IPC: A47L9/28
Filed: 1989-02-23
Abstract: PURPOSE:To prevent a motor from being overheated by providing a timer means to force an output change-over switch means to change back to the first output operation mode when a given time has passed since it is changed over to the second output operation mode. CONSTITUTION:When an operator intends to catch ticks while cleaning rooms and pushes a shot power switch SW1 an example of output change-over switch means provided in an operation part 7 close to a handle 6 near at hand, an electric circuit actuates the switch to change over to the second output operation mode which generates higher power than the first output operation mode. For another example, when an operator goes on pushing the shot power switch SW1 for the wide area of catching ticks and the second output operation mode is continued to be operated, a timer circuit 10 an example of timer means provided in the operation part 7 works and forces the switch to change back to the first output operation mode when a given time has passed since it is changed over to the second output operation mode. Therefore, a motor of a vacuum cleaner is prevented from being overheated.

Title: Active noise canceler
Inventor: SAEKI TAKAFUMI
IPC: H04R3/00
Filed: 1989-02-25
Abstract: PURPOSE:To attain stable high noise eliminating performance by providing a bypass equivalent circuit in parallel with a noise eliminating speaker and a monitor microphone and using a subtraction circuit so as to subtract one of two signals being an input signal from the monitor microphone and a bypass signal from the bypass equivalent circuit from the other. CONSTITUTION:A cancel tone generating signal F outputted from a noise cancel circuit 3 is inputted to a parallel bypass equivalent circuit 4. The bypass equivalent circuit 4 gives a signal change equivalent to a signal change (phase lag and gain change) when the cancel tone generating signal reaches a preamplifier 3a from a branch point G via a noise eliminating speaker 1 and the monitor microphone 2 to form a bypass signal H. Thus, when a subtraction circuit 3b subtracts the bypass signal H from the bypass equivalent circuit 4 from the input signal D from the monitor microphone 2, since the component of the cancel tone A included in the input signal D is equivalent to the bypass tone signal H, the component is eliminated completely by the subtraction to prevent production of howling.

IPC: G06F15/02
Filed: 1984-03-10
Abstract: PURPOSE:To make chart preparing work quick, by combining a computing function device, which includes a keyboard part that inputs numerical values, operating symbols and the like and a number and symbol part having an electric display means, and a scale display part having an electric display means. CONSTITUTION:An electric scale has a computing function device, which includes a keyboard part 5 that inputs numerical values, operating symbols and the like and a number and symbol display part 6 having an electric display means, and a scale display part having an electric display means. For example, when a chart having a length of 3.33cm is prepared, the number 3.33 is inputted to the keyboard 5. Then the number 3.33 is displayed on the number and symbol displaying part 6. A segment 6 having the length of 3.33cm and a scale 8 indicating both ends of the segment are displayed on the scale display part 2. Thus the segment can be displayed on the scale display part without otherwise computing an applying the actual segment by the chart drawing person himself and the chart can be preapred quickly.

Title: Transmission type screen
Inventor: FUNAKOSHI YASUTOMO
IPC: G03B21/62
Filed: 1979-04-12
Abstract: PURPOSE: To obtain the transmission-type screen which permits sufficient observation even in a bright room by using the lenticular lens provided with a Fresnel lens and diffusion face.  
     CONSTITUTION: A Fresnel lens 2 of concentrical form of pitch 0.2mm is formed on one plane of a transparent polymethyl methacrylate of a refractive index 1.492. Also, a lenticular lens 3 of pitch 0.1mm is formed on the plane opposing to the plane of this Fresnel lens 2 and a diffusion face 4 of surface roughness 0.5μ is formed on the surface of this lenticular lens 3. Directivity is controlled by the lenticular lens 3 and condensing characteristic is controlled by the Fresnel lens 2. Since incident rays do not enter the layer having the diffusion face 4 and their reflection is less, the transmittance does not lower. Hence, the high-luminance transmission type screen having a light transmittance of 90% or more is obtained.

Title: Production of solid-lubricant-containing bushing
Inventor: KITA YOSHIAKI
IPC: B22D19/14
Filed: 1979-04-13
Abstract: PURPOSE: To produce the captioned bushing having abrasion resistance and high strength by pouring molten alloy metal containing graphite powder into a cylindrical mold which is rotating at a high speed about its axial line, letting the same solidify after the lapse of a suitable time and dispersing graphite powder more densely in the inside circumferential surface than in the outside circumferential surface.  
     CONSTITUTION: While the mold 3 is being rotated together with a rotary disc 1 which is rotated at a high speed by a variable speed motor, the molten metal 6 on the alloy containing 1W40vol% of graphite powder [e.g.; copper alloy (5Sn- 5Zn-4Pb-0.5P-rest Cu)] is poured into this mold 3. This molten metal 6 is deposited on the inside circumferential wall surface of the mold 3 to an even thickness. As a result of this, the graphite powder 5 which had evenly dispersed in the molten metal 6 is more densely dispersed in the inside circumferential surface than in the outside circumferential surface owing to a difference in specific gravity from the alloy. Next, the molten metal 6 is solidified and the resultant solid-lubricant (graphite powder)-containing bushing has abrasion resistance of its sliding surface and has the strength close to the strength of the matrix at its outside circumferential part.
