Title: Manufacture of mask for x-ray lithography
Inventor: GOTO TAKASHI
IPC: G03F1/68
Filed: 1989-06-29
Abstract: PURPOSE:To form an X-ray absorber pattern having a high aspect ratio by a method wherein at least a double-layer structure consisting of a first absorption layer of X-ray absorber and a second absorbing layer to be superposed thereon, is formed and after a second absorption layer has been patterned, a patterning operation is conducted on a first absorption layer using the second absorption layer as a mask. CONSTITUTION:The main surface of a silicon substrate 1 is coated with a first absorption layer 3 through the intermediary of a supporting film 2 consisting of a silicon nitride film and the like, and a resist pattern 4 is formed thereon. The first absorption layer 3 is formed with Ta, for example, and its film thickness is 500Angstrom or thereabout. The resist pattern 4 consists of an organic resist. The first absorption layer 3, including the resist pattern 4, is coated with a second absorption layer 5. This layer 5 consists of Au and has the thickness of 300Angstrom  or thereabout. The second absorption layer on the resist pattern 4 is removed by a lift-off function, and as a result, the patterned second absorption layer 5 is left. A patterning operation is conducted on the first absorption layer 3 using the second absorption layer 5 as a mask. The anisotropic etching method such as a reactive ion etching, a reactive ion beam etching and the like are used for the above-mentioned patterning.

Title: Copying machine with automatic original feeder
Inventor: TAKAMIYA YOSHIO
IPC: G03G15/00
Filed: 1985-07-31
Abstract: PURPOSE:To prevent a copying paper from being used uselessly by detecting whether an image is present or not on an original surface to be opposite contact glass and stopping a transfer process system not so as to output a white copy when the image is not provided. CONSTITUTION:When originals are sequentially fed one by one out of an original platen 3, it is assumed that the original to be fed turns inside out at some point, and there is no image on the surface of the contact glass side of the original. At this time, such a state is detected by a detector 8, and due to this detecting signal the transfer process system is automatically stopped. Thus a useless copying is not made, whereby a copying paper is not uselessly consumed.

Title: Prior inspecting method of concrete quality
Inventor: WADA SADAO
IPC: G01N33/38
Filed: 1979-12-25
Abstract: PURPOSE: To rapidly inspect the adequateness or not of concrete quality prior to placement of concrete by deciding water-cement ratios.  
     CONSTITUTION: At the unloading point from a ready-mixed concrete car, a suitable amount of ready-mixed concrete is sampled into a bucket 1. After gravel is separated with a sieve 2, mortar (a) for measuring water amount and mortar (b) for measuring cement amount are weighed. The mortar (a) of constant volume is put into an Erlenmeyer flask and the temp.-corrected underwater weight U is measured by using a balance 12 and a thermometer 8. Also, the mortar (b) is put into a constant volume measuring flask 4, and while it is repeatedly stirred and allowed to stand, the temp.-corrected specific gravity is measured with a hydrometer 7 and the thermometer 8. Cement amount C is obtained from the measured values and the specific gravity-cement amount relation data having beforehand been obtained, and further, water amount W is obtained based on the underwater weight U, the cement amount C and the specific gravity of the cement and aggregate having beforehand been obtained. From the water amount W and the cement amount C, a water- cement ratio W/C is obtained. Thereby, whether the ready-mixed concrete is of the quality at which necessary strength is obtainable after setting or not is decided prior to placement of the concrete.

IPC: F02B3/06
Filed: 1989-06-30
Abstract: PURPOSE:To prevent explosion of residual fuel by stopping the fuel supply when the glow plug temp. sinks below a specified value during starting period, and performing cranking forcedly in a certain period for scavenging. CONSTITUTION:Methanol fuel is injected into the fuel chamber of an engine E from a fuel injecting means F and ignited forcedly with a glow plug. The starting motion is sensed by a start sensing means A, and the temp. is sensed by a glow plug temp. sensing means B. Upon receiving the output therefrom a fuel stop means C stops supply of the fuel made by a fuel injecting means F if the temp. sinks below a specified value in the starting process. A forced cranking is made by a forced cranking means D for a certain period of time from the time when the temp has sunk below the specified value. This scavenges the residual combustible gas out of the fuel chamber, which prevents explosion due to temp. rise of glow plug G to lead to enhancement of the safety.
