  • Publication number: 20230384816
    Abstract: An input device includes an operation shaft extending in a first direction, linearly movable in the first direction, and having a tip portion; a force sensation generator configured to apply a force to the operation shaft; a sensor configured to detect an amount of movement of the operation shaft; a range-of-motion adjuster configured to change a maximum push-in position of the operation shaft; and a range-of-motion adjustment motor configured to operate the range-of-motion adjuster. The range-of-motion adjuster has a contact portion with which the tip portion of the operation shaft comes into contact. The range-of-motion adjuster changes the maximum push-in position of the operation shaft by being operated to change a contact position of the tip portion with respect to the contact portion in the first direction.

  • Publication number: 20230339928
    Abstract: The present disclosure relates to novel processes for the preparation of compounds of Formula I. Some of these compounds are useful as stimulators of soluble guanylate cyclase (sGC). Others are useful intermediates towards the preparation of said stimulators. These processes are amenable to large scale preparation and produce stable 3-(2-pyrimidinyl)pyrazoles of Formula I in high purity and yields. The present invention has the additional advantage of facile reaction conditions, amenable to scale up for large scale manufacturing. The disclosure also provides novel intermediates useful in the preparation of said compounds.
