Title: Auxiliary tool for preventing fall from ladder
Inventor: OGAWA HIROSHI
IPC: E04G21/32
Filed: 1999-09-28
Abstract: PROBLEM TO BE SOLVED: To prevent a worker from falling from a ladder. SOLUTION: An auxiliary tool 4 is comprised of an almost circular ring auxiliary tool main body 5 and a pair of attaching portions 6 formed at both ends of the auxiliary tool main body 5, for detachably attaching the main body 5 to a ladder 1. Each attaching portion 6 is supported by the ladder 1 at three portions thereof, so as not to be easily detached from the ladder 1. The operator 8 can climb up/down the ladder 1 through a space defined by the auxiliary tool 4 and the ladder 1. When the worker 8 looses his gripping or footing from the ladder 1 by mistake, since the back, hands, and/or feet of the worker 8 can be held by the auxiliary tool 4, he can be prevented from falling from the ladder 1.

Title: Manufacture of semiconductor device
Inventor: KITANO NAOKI
IPC: H01L21/306
Filed: 1988-10-31
Abstract: PURPOSE:To manufacture a semiconductor device with less damage to a semiconductor substrate by a method wherein a resist or projections of an insulating film are removed by a wet-etching process. CONSTITUTION:A resist 1 only is selectively etched i.e., the resist 1 is wet-etched using a chemical solution etching the resist 1 only without etching an insulating film 2 e.g., a solution containing acetone:water =1:2 to etch the resist 1 until the surface of projections 5 of the insulating film 2 is exposed. The surface of the projections 5 can be etched until they are exposed by controlling the etching time by previously deciding the etching rate of the resist 1 using the acetone water solution. Next, SiO2 forming the projections 5 is removed using the solution etching the insulating film 2 only. At this time, in the recessions 6, the projections 5 only are etched due to the residual resist during the process working as a mask. Consequently, the projections 5 can be etched to be flattened.

Title: Peak speed control circuit for variable rate transmission device
Inventor: FUJINO SHOJI
IPC: H04L12/70
Filed: 1988-10-31
Abstract: PURPOSE:To control the peak speed for transmission of data by performing the variable control for the data transfer speed between a 1st store means which stores temporarily the produced data and a 2nd store means which transmits the data to a transmission line. CONSTITUTION:The coding information produced by a picture coder 21 is sequentially stored in a buffer memory 22 at a fixed rate. When the quantity of data stored in the memory 22 is approximate to an overflow state, a control signal is sent to the coder 21. Thus the coder 21 omits the frames to suppress the quantity of produced information and the prevent the overflow of the memory 22. Then the data stored in the memory 22 are transferred to a buffer memory 23 at a variable rate decided by the frequency of a variable oscillator 25. The frequency of the oscillator 25 is varied by the situation of a network. Thus the generating frequency of the packet to be transferred is controlled according to the network situation. Then the peak speed is controlled for transmission of data.

Title: Sample-and-hold circuit
Inventor: NAKAHIRA MAMORU
IPC: H01L29/78
Filed: 1987-10-31
Abstract: PURPOSE:To decrease an A/D conversion error due to the generation of a noise by sufficiently enlarging the area of the P-N linking part of a diode laid between an input terminal and the power source of a circuit and/or a ground compared with the area of the P-N linking part of a source diffusion layer of a MOS electric field effect transistor (TR) consisting of an analog switch. CONSTITUTION:Between analog input terminals AN0 and AN1 and a power source VDD of a sample holding circuit and/or a ground, diodes D11-D14 are laid. For the P-N linking part of the diodes D11-D14, the area is sufficiently larger compared with the P-N linking part of the source diffusion layer of MOS electric field effect TRs T11-T14. Thus, even when the voltage higher than a supply voltage or lower than the grounding potential is impressed to one of an analog input terminal due to the generation of the noise during an A/D conversion, the generation of the A/D conversion error can be evated.
