Title: Drafting apparatus
Inventor: HANSU YOAHIMU SHIYUROTSUTO
IPC: G01D5/245
Filed: 1989-10-13
Abstract: PURPOSE: To execute accurate drawing by a simple constitution by providing at least two magnetic field sensors which are juxtaposed in the longitudinal direction of a strip-shaped body constituted of a magnetized material and forming a length scale, and are fixed as scanning devices at the same height from a support surface of a drawing rail. CONSTITUTION: Magnetic field sensors are buried in a drawing rail 10 so that they pass sequentially a specified N pole of a strip-shaped body 7 and then an S pole adjacent thereto on the occasion when the rail is slid along a guide rib 3 of a drawing board. When the drawing rail 10 including a chip or module 20 is moved along the guide rib 3 of the drawing board 1, starting from a prescribed space between the N pole and the adjacent S pole in this strip-shaped body 7, an output voltage transition corresponding to the figure is obtained in an output of a bridge circuit. In this case, shifts of both curves U1 and U2 are given by a spatial distance between the magnetic field sensors 21 and 22 of the module or chip 20. The periods of the curves are at prescribed intervals and the curves have substantially-linear parts as shown by thick lines in the figure.  Accordingly, the position of contact of the drawing rail 11 can be determined very accurately within the range of the prescribed space on the basis of these linear parts.

Title: Production of high-purity pyromellitic anhydride
Inventor: HARA TADANORI
IPC: C07D493/04
Filed: 1991-09-18
Abstract: PURPOSE:To obtain the subject compound useful as a raw material, etc., for polymers in high purity and yield by oxidizing a tetraalkylbenzene in the vapor phase, then cooling the resultant reactional product gas, and further washing and recrystallizing the cooled deposited pyromellitic anhydride with a solvent. CONSTITUTION:A tetraalkylbenzene is oxidized with an oxygen-containing gas in the vapor phase in the presence of a catalyst such as vanadium at 300-450 deg.C to provide pyromellitic anhydride. The resultant oxidation reactional product gas is subsequently cooled to deposit the pyromellitic anhydride, which is then collected. The taken out pyromellitic anhydride is heated at >=50 deg.C and washed with a medium solvent (e.g. 1,4-dioxane). Furthermore, the washed pyromellitic anhydride is heated at 130-180 deg.C and recrystallized with a good solvent (e.g. gamma-butyrolactone) so as to provide higher purity, improve color tone and regulate properties of crystals. Thereby, the objective substance is obtained.

Title: Humidifier
Inventor: KIZAWA TOSHIHIRO
IPC: F24F6/06
Filed: 1999-09-20
Abstract: PROBLEM TO BE SOLVED: To provide a humidifier having a high humidifying efficiency by reducing air between a humidifying channel and a moisture-absorption channel. SOLUTION: A moisture-absorption-side fan motor 14 and a humidifying-side fan motor 17 are provided downstream of a humidifying rotor 12 to produce a negative pressure in both of a humidifying channel 13 and a moisture- absorption channel 15 in the vicinity of the end surfaces of the humidifying rotor 12. As a result, the difference in pressure between air in the humidifying channel 15 and air in the moisture-absorption channel 13 is small in the vicinity of the end surfaces of the humidifying rotor 12 and consequently leakage of air is reduced so that the humidifying efficiency is improved. Both of the moisture-absorption-side fan motor 14 and the humidifying-side fan motor 17 are arranged at the same lower side of the humidifying rotor 12 to miniaturize the humidifier.

Title: Prom writer
Inventor: NAKAMURA NAOTO
IPC: G11C17/00
Filed: 1987-10-20
Abstract: PURPOSE:To generate a PROM without a special program and a general interface by reading out a PROM write data by a DMA from a memory of an address designated by a lower limit address setting switch and an upper limit address setting switch and writing it in the PROM. CONSTITUTION:When a write start switch 9 of a PROM writer 1 is turned on, a DMA (direct memory access) circuit 5 reads out a PROM-converted data by a direct memory access from a memory 4 of an execution CPU 2 which is set by a lower limit address setting switch 8. The PROM-converted data which is read out is written in a PROM by a PROm writing circuit 6. When a transfer of once is ended, the DMA circuit 5 brings an internal memory address counter to increment, and the next memory address data is outputted from the DMA circuit 5. Also, the write operation is executed repeatedly to an address which is set by an upper limit address setting switch 7. In such a way, the PROM can be generated easily.

Title: One-chip processor
Inventor: SATO TADASHI
IPC: G06F1/00
Filed: 1986-11-10
Abstract: PURPOSE:To reduce the power consumption of a 1-chip processor by controlling only a RAM module of small capacity necessary for execution of instructions under an accessable state. CONSTITUTION:A CS 2-1 consisting of plural RAM modules 2 is set to a CSDR 3-3 by an address in an address register 3-1. The contents of the CSDR 3-3 are decoded by an instruction decoder 3-4 for control of the inside of a 1-chip processor 1. A module address comparator 3-31 sets a dummy FF 3-32 in the case of different RAM addresses. Under such conditions, a CS control circuit 3-33 performs control to apply an executing cycle to the access 2 of the RAM module. This RAM module consumes minute power consumption and the FF 3-32 is set when said RAM module is switched to the access of another RAM module. Thus the access is prolonged against the RAM module.
